sqlcmd utility lets you enter Transact-SQL statements, system procedures, and script files at the command prompt, in Query Editor in SQLCMD mode, in a Windows script file or in an operating system (Cmd.exe) job step of a SQL Server Agent job. This utility uses ODBC to execute Transact-SQL batches.
sqlcmd does not require a space between the command line option and the value. However, in a future release, a space may be required between the command line option and the value.
sqlcmd -a packet_size -A (dedicated administrator connection) -b (terminate batch job if there is an error) -cbatch_terminator-C (trust the server certificate) -ddb_name-e (echo input) -E (use trusted connection) -fcodepage | i:codepage[,o:codepage] | o:codepage[,i:codepage] -hrows_per_header-Hworkstation_name-iinput_file-I (enable quoted identifiers) -k[1 | 2] (remove or replace control characters) -Kapplication_intent-llogin_timeout-L[c] (list servers, optional clean output) -merror_level-Mmultisubnet_failover-N (encrypt connection) -ooutput_file-p (print statistics, optional colon format) -Ppassword-q "cmdline query"-Q "cmdline query" (and exit) -r[0 | 1] (msgs to stderr) -R (use client regional settings) -scol_separator-S [protocol:]server[\instance_name][,port] -tquery_timeout-u (unicode output file) -Ulogin_id-vvar = "value"-Verror_severity_level-wcolumn_width-W (remove trailing spaces) -x (disable variable substitution) -X (disable commands, startup script, environment variables and optional exit) -yvariable_length_type_display_width-Yfixed_length_type_display_width-znew_password -Znew_password (and exit) -? (usage)
Logs in to SQL Server with a Dedicated Administrator Connection (DAC). This kind of connection is used to troubleshoot a server. This will only work with server computers that support DAC. If DAC is not available,
sqlcmd generates an error message and then exits. For more information about DAC, see Diagnostic Connection for Database Administrators.
This switch is used by the client to configure it to implicitly trust the server certificate without validation. This option is equivalent to the ADO.NET option
TRUSTSERVERCERTIFICATE = true.
USE db_name statement when you start
sqlcmd. This option sets the
sqlcmd scripting variable SQLCMDDBNAME. This specifies the initial database. The default is your login's default-database property. If the database does not exist, an error message is generated and
Specifies the number of seconds before a
sqlcmd login to the ODBC driver times out when you try to connect to a server. This option sets the
sqlcmd scripting variable SQLCMDLOGINTIMEOUT. The default time-out for login to
sqlcmd is eight seconds. The login time-out must be a number between 0 and 65534. If the value supplied is not numeric or does not fall into that range,
sqlcmd generates an error message. A value of 0 specifies time-out to be infinite.
Uses a trusted connection instead of using a user name and password to log on to SQL Server. By default, without -E specified,
sqlcmd uses the trusted connection option.
The -E option ignores possible user name and password environment variable settings such as SQLCMDPASSWORD. If the -E option is used together with the -U option or the -P option, an error message is generated.
A workstation name. This option sets the
sqlcmd scripting variable SQLCMDWORKSTATION. The workstation name is listed in the hostname column of the sys.processes catalog view and can be returned using the stored procedure sp_who. If this option is not specified, the default is the current computer name. This name can be used to identify different
Declares the application workload type when connecting to a server. The only currently supported value is ReadOnly. If -K is not specified, the sqlcmd utility will not support connectivity to a secondary replica in an AlwaysOn availability group. For more information, see Active Secondaries: Readable Secondary Replicas.
-M when connecting to the availability group listener of a SQL Server availability group or a SQL Server Failover Cluster Instance.
-M provides for faster detection of and connection to the (currently) active server. If
–M is not specified,
-M is off. For more information about Always On Availability Groups, see Availability Group Listeners, Client Connectivity, and Application Failover (SQL Server), Creation and Configuration of Availability Groups (SQL Server), Failover Clustering and AlwaysOn Availability Groups (SQL Server), and Active Secondaries: Readable Secondary Replicas .
This switch is used by the client to request an encrypted connection.
Is a user-specified password. Passwords are case sensitive. If the -U option is used and the -P option is not used, and the SQLCMDPASSWORD environment variable has not been set,
sqlcmd prompts the user for a password. If the -P option is used at the end of the command prompt without a password
sqlcmd uses the default password (NULL).
The password prompt is displayed by printing the password prompt to the console, as follows:
User input is hidden. This means that nothing is displayed and the cursor stays in position.
The SQLCMDPASSWORD environment variable lets you set a default password for the current session. Therefore, passwords do not have to be hard-coded into batch files.
The following example first sets the SQLCMDPASSWORD variable at the command prompt and then accesses the
sqlcmd utility. At the command prompt, type:
SET SQLCMDPASSWORD= p@a$$w0rd
At the following command prompt, type:
If the user name and password combination is incorrect, an error message is generated.
If the -P option is used with the -E option, an error message is generated.
If the -P option is followed by more than one argument, an error message is generated and the program exits.
Specifies the instance of SQL Server to which to connect. It sets the
sqlcmd scripting variable SQLCMDSERVER.
Specify server_name to connect to the default instance of SQL Server on that server computer. Specify server_name [ \instance_name ] to connect to a named instance of SQL Server on that server computer. If no server computer is specified,
sqlcmd connects to the default instance of SQL Server on the local computer. This option is required when you execute
sqlcmd from a remote computer on the network.
protocol can be
lpc (shared memory), or
np (named pipes).
If you do not specify a server_name [ \instance_name ] when you start
sqlcmd, SQL Server checks for and uses the SQLCMDSERVER environment variable.
Is the user login ID.
If neither the -U option nor the -P option is specified,
sqlcmd tries to connect by using Microsoft Windows Authentication mode. Authentication is based on the Windows account of the user who is running
If the -U option is used with the -E option (described later in this topic), an error message is generated. If the –U option is followed by more than one argument, an error message is generated and the program exits.
sqlcmd -U someuser -P s0mep@ssword -z a_new_p@a$$w0rd
Change password and exit:
sqlcmd -U someuser -P s0mep@ssword -Z a_new_p@a$$w0rd
-f codepage | i:codepage[,o:codepage] | o:codepage[,i:codepage]
Specifies the input and output code pages. The codepage number is a numeric value that specifies an installed Windows code page.
Code-page conversion rules:
If no code pages are specified,
sqlcmdwill use the current code page for both input and output files, unless the input file is a Unicode file, in which case no conversion is required.
sqlcmdautomatically recognizes both big-endian and little-endian Unicode input files. If the -u option has been specified, the output will always be little-endian Unicode.
If no output file is specified, the output code page will be the console code page. This enables the output to be displayed correctly on the console.
Multiple input files are assumed to be of the same code page. Unicode and non-Unicode input files can be mixed.
chcp at the command prompt to verify the code page of Cmd.exe.
Identifies the file that contains a batch of SQL statements or stored procedures. Multiple files may be specified that will be read and processed in order. Do not use any spaces between file names.
sqlcmd will first check to see whether all the specified files exist. If one or more files do not exist,
sqlcmd will exit. The -i and the -Q/-q options are mutually exclusive.
-i "C:\Some Folder\<file name>"
File paths that contain spaces must be enclosed in quotation marks.
This option may be used more than once: -iinput_file -II input_file.
Identifies the file that receives output from
If -u is specified, the output_file is stored in Unicode format. If the file name is not valid, an error message is generated, and
sqlcmd does not support concurrent writing of multiple
sqlcmd processes to the same file. The file output will be corrupted or incorrect. See the -f switch for more information about file formats. This file will be created if it does not exist. A file of the same name from a prior
sqlcmd session will be overwritten. The file specified here is not the stdout file. If a stdout file is specified this file will not be used.
-o C:\< filename>
-o "C:\Some Folder\<file name>"
File paths that contain spaces must be enclosed in quotation marks.
-r[0 | 1]
Redirects the error message output to the screen (stderr). If you do not specify a parameter or if you specify 0, only error messages that have a severity level of 11 or higher are redirected. If you specify 1, all error message output including PRINT is redirected. Has no effect if you use -o. By default, messages are sent to stdout.
sqlcmd to localize numeric, currency, date, and time columns retrieved from SQL Server based on the client’s locale. By default, these columns are displayed using the server’s regional settings.
Specifies that output_file is stored in Unicode format, regardless of the format of input_file.
Query Execution Options
Writes input scripts to the standard output device (stdout).
Sets the SET QUOTED_IDENTIFIER connection option to ON. By default, it is set to OFF. For more information, see SET QUOTED_IDENTIFIER (Transact-SQL).
-q" cmdline query "
Executes a query when
sqlcmd starts, but does not exit
sqlcmd when the query has finished running. Multiple-semicolon-delimited queries can be executed. Use quotation marks around the query, as shown in the following example.
At the command prompt, type:
sqlcmd -d AdventureWorks2012 -q "SELECT FirstName, LastName FROM Person.Person WHERE LastName LIKE 'Whi%';"
sqlcmd -d AdventureWorks2012 -q "SELECT TOP 5 FirstName FROM Person.Person;SELECT TOP 5 LastName FROM Person.Person;"
-b is specified together with this option,
sqlcmd exits on error.
-b is described later in this topic.
-Q" cmdline query "
Executes a query when
sqlcmd starts and then immediately exits
sqlcmd. Multiple-semicolon-delimited queries can be executed.
Use quotation marks around the query, as shown in the following example.
At the command prompt, type:
sqlcmd -d AdventureWorks2012 -Q "SELECT FirstName, LastName FROM Person.Person WHERE LastName LIKE 'Whi%';"
sqlcmd -d AdventureWorks2012 -Q "SELECT TOP 5 FirstName FROM Person.Person;SELECT TOP 5 LastName FROM Person.Person;"
-b is specified together with this option,
sqlcmd exits on error.
-b is described later in this topic.
Specifies the number of seconds before a command (or SQL statement) times out. This option sets the
sqlcmd scripting variable SQLCMDSTATTIMEOUT. If a time_out value is not specified, the command does not time out. The querytime_out must be a number between 1 and 65534. If the value supplied is not numeric or does not fall into that range,
sqlcmd generates an error message.
-vvar = value[ var = value...]
sqlcmdscripting variable that can be used in a
sqlcmd script. Enclose the value in quotation marks if the value contains spaces. You can specify multiple var="
values"** values. If there are errors in any of the values specified,
sqlcmd generates an error message and then exits.
sqlcmd -v MyVar1=something MyVar2="some thing"
sqlcmd -v MyVar1=something -v MyVar2="some thing"
sqlcmd to ignore scripting variables. This is useful when a script contains many INSERT statements that may contain strings that have the same format as regular variables, such as $(variable_name).
Specifies the number of rows to print between the column headings. The default is to print headings one time for each set of query results. This option sets the
sqlcmd scripting variable SQLCMDHEADERS. Use -1 to specify that headers must not be printed. Any value that is not valid causes
sqlcmd to generate an error message and then exit.
-k [1 | 2]
Removes all control characters, such as tabs and new line characters from the output. This preserves column formatting when data is returned. If 1 is specified, the control characters are replaced by a single space. If 2 is specified, consecutive control characters are replaced by a single space. -k is the same as -k1.
Specifies the column-separator character. The default is a blank space. This option sets the
sqlcmd scripting variable SQLCMDCOLSEP. To use characters that have special meaning to the operating system such as the ampersand (&), or semicolon (;), enclose the character in quotation marks ("). The column separator can be any 8-bit character.
Specifies the screen width for output. This option sets the
sqlcmd scripting variable SQLCMDCOLWIDTH. The column width must be a number greater than 8 and less than 65536. If the specified column width does not fall into that range,
sqlcmd generates and error message. The default width is 80 characters. When an output line exceeds the specified column width, it wraps on to the next line.
This option removes trailing spaces from a column. Use this option together with the -s option when preparing data that is to be exported to another application. Cannot be used with the -y or -Y options.
sqlcmd scripting variable SQLCMDMAXVARTYPEWIDTH. The default is 256. It limits the number of characters that are returned for the large variable length data types:
UDT (user-defined data types)
sqlcmd scripting variable SQLCMDMAXFIXEDTYPEWIDTH. The default is 0 (unlimited). Limits the number of characters that are returned for the following data types:
), where 1<=n<=8000
), where 1<=n<=4000
), where 1<=n<=8000
), where 1<=n<=4000
), where 1<=n<=4000
Error Reporting Options
sqlcmd exits and returns a DOS ERRORLEVEL value when an error occurs. The value that is returned to the DOS ERRORLEVEL variable is 1 when the SQL Server error message has a severity level greater than 10; otherwise, the value returned is 0. If the
-V option has been set in addition to
sqlcmd will not report an error if the severity level is lower than the values set using
-V. Command prompt batch files can test the value of ERRORLEVEL and handle the error appropriately.
sqlcmd does not report errors for severity level 10 (informational messages).
sqlcmd script contains an incorrect comment, syntax error, or is missing a scripting variable, ERRORLEVEL returned is 1.
Controls which error messages are sent to stdout. Messages that have a severity level greater than or equal to this level are sent. When this value is set to -1, all messages including informational messages, are sent. Spaces are not allowed between the -m and -1. For example, -m-1 is valid, and -m-1 is not.
This option also sets the
sqlcmd scripting variable SQLCMDERRORLEVEL. This variable has a default of 0.
Controls the severity level that is used to set the ERRORLEVEL variable. Error messages that have severity levels greater than or equal to this value set ERRORLEVEL. Values that are less than 0 are reported as 0. Batch and CMD files can be used to test the value of the ERRORLEVEL variable.
Requests a packet of a different size. This option sets the
sqlcmd scripting variable SQLCMDPACKETSIZE. packet_size must be a value between 512 and 32767. The default = 4096. A larger packet size can enhance performance for execution of scripts that have lots of SQL statements between GO commands. You can request a larger packet size. However, if the request is denied,
sqlcmd uses the server default for packet size.
Specifies the batch terminator. By default, commands are terminated and sent to SQL Server by typing the word "GO" on a line by itself. When you reset the batch terminator, do not use Transact-SQL reserved keywords or characters that have special meaning to the operating system, even if they are preceded by a backslash.
Lists the locally configured server computers, and the names of the server computers that are broadcasting on the network. This parameter cannot be used in combination with other parameters. The maximum number of server computers that can be listed is 3000. If the server list is truncated because of the size of the buffer a warning message is displayed.
If the optional parameter c is specified, the output appears without the Servers: header line and each server line is listed without leading spaces. This is referred to as clean output. Clean output improves the processing performance of scripting languages.
Prints performance statistics for every result set. The following is an example of the format for performance statistics:
Network packet size (bytes): n
Clock Time (ms.): total t1 avg t2 (t3 xacts per sec.)
x = Number of transactions that are processed by SQL Server.
t1 = Total time for all transactions.
t2 = Average time for a single transaction.
t3 = Average number of transactions per second.
All times are in milliseconds.
If the optional parameter 1 is specified, the output format of the statistics is in colon-separated format that can be imported easily into a spreadsheet or processed by a script.
If the optional parameter is any value other than 1, an error is generated and
Disables commands that might compromise system security when
sqlcmd is executed from a batch file. The disabled commands are still recognized;
sqlcmd issues a warning message and continues. If the optional parameter 1 is specified,
sqlcmd generates an error message and then exits. The following commands are disabled when the
-X option is used:
-X option is specified, it prevents environment variables from being passed on to
sqlcmd. It also prevents the startup script specified by using the SQLCMDINI scripting variable from being executed. For more information about
sqlcmd scripting variables, see Use sqlcmd with Scripting Variables.
Displays the syntax summary of
Options do not have to be used in the order shown in the syntax section.
When multiple results are returned,
sqlcmd prints a blank line between each result set in a batch. In addition, the "<x> rows affected" message does not appear when it does not apply to the statement executed.
sqlcmd interactively, type
sqlcmd at the command prompt with any one or more of the options described earlier in this topic. For more information, see Use the sqlcmd Utility

R indicates the value can only be set one time during program initialization.
R/W indicates that the value can be modified by using the setvar command and subsequent commands will be influenced by the new value.
In addition to Transact-SQL statements within
sqlcmd, the following commands are also available:
|[:] EXIT||:On Error|
|:ServerList||:XML [ON | OFF]|
Be aware of the following when you use
sqlcmdcommands, except GO, must be prefixed by a colon (:).
To maintain backward compatibility with existing osql scripts, some of the commands will be recognized without the colon. This is indicated by the [:].
sqlcmdcommands are recognized only if they appear at the start of a line.
sqlcmdcommands are case insensitive.
Each command must be on a separate line. A command cannot be followed by a Transact-SQL statement or another command.
Commands are executed immediately. They are not put in the execution buffer as Transact-SQL statements are.
Starts the text editor. This editor can be used to edit the current Transact-SQL batch, or the last executed batch. To edit the last executed batch, the ED command must be typed immediately after the last batch has completed execution.
The text editor is defined by the SQLCMDEDITOR environment variable. The default editor is 'Edit'. To change the editor, set the SQLCMDEDITOR environment variable. For example, to set the editor to Microsoft Notepad, at the command prompt, type:
Clears the statement cache.
Prints the content of the statement cache.
:Setvar <var> [ "
sqlcmd scripting variables. Scripting variables have the following format:
Variable names are case insensitive.
Scripting variables can be set in the following ways:
Implicitly using a command-line option. For example, the -l option sets the SQLCMDLOGINTIMEOUT
Explicitly by using the :Setvar command.
By defining an environment variable before you run
If a variable defined by using :Setvar and an environment variable have the same name, the variable defined by using :Setvar takes precedence.
Variable names must not contain blank space characters.
Variable names cannot have the same form as a variable expression, such as $(var).
If the string value of the scripting variable contains blank spaces, enclose the value in quotation marks. If a value for a scripting variable is not specified, the scripting variable is dropped.
Displays a list of the scripting variables that are currently set.
< filename >| STDERR|STDOUT
Redirect all error output to the file specified by file name, to stderr or to stdout. The Error command can appear multiple times in a script. By default, error output is sent to stderr.
Creates and opens a file that will receive the output. If the file already exists, it will be truncated to zero bytes. If the file is not available because of permissions or other reasons, the output will not be switched and will be sent to the last specified or default destination.
Switches error output to the stderr stream. If this has been redirected, the target to which the stream has been redirected will receive the error output.
Switches error output to the stdout stream. If this has been redirected, the target to which the stream has been redirected will receive the error output.
:Out < filename >| STDERR| STDOUT
Creates and redirects all query results to the file specified by file name, to stderr or to stdout. By default, output is sent to stdout. If the file already exists, it will be truncated to zero bytes. The Out command can appear multiple times in a script.
:Perftrace < filename >| STDERR| STDOUT
Creates and redirects all performance trace information to the file specified by file name, to stderr or to stdout. By default performance trace output is sent to stdout. If the file already exists, it will be truncated to zero bytes. The Perftrace command can appear multiple times in a script.
Execution Control Commands
Sets the action to be performed when an error occurs during script or batch execution.
exit option is used,
sqlcmd exits with the appropriate error value.
ignore option is used,
sqlcmd ignores the error and continues executing the batch or script. By default, an error message will be printed.
sqlcmd to exit.
[:] EXIT[ (
Lets you use the result of a SELECT statement as the return value from
sqlcmd. If numeric, the first column of the last result row is converted to a 4-byte integer (long). MS-DOS passes the low byte to the parent process or operating system error level. Windows 200x passes the whole 4-byte integer. The syntax is:
You can also include the EXIT parameter as part of a batch file. For example, at the command prompt, type:
sqlcmd -Q "EXIT(SELECT COUNT(*) FROM '%1')"
sqlcmd utility sends everything between the parentheses () to the server. If a system stored procedure selects a set and returns a value, only the selection is returned. The EXIT() statement with nothing between the parentheses executes everything before it in the batch and then exits without a return value.
When an incorrect query is specified,
sqlcmd will exit without a return value.
Here is a list of EXIT formats:
Does not execute the batch, and then quits immediately and returns no value.
- :EXIT( )
Executes the batch, and then quits and returns no value.
Executes the batch that includes the query, and then quits after it returns the results of the query.
If RAISERROR is used within a
sqlcmd script and a state of 127 is raised,
sqlcmd will quit and return the message ID back to the client. For example:
RAISERROR(50001, 10, 127)
This error will cause the
sqlcmd script to end and return the message ID 50001 to the client.
The return values -1 to -99 are reserved by SQL Server;
sqlcmd defines the following additional return values:
|-100||Error encountered prior to selecting return value.|
|-101||No rows found when selecting return value.|
|-102||Conversion error occurred when selecting return value.|
GO signals both the end of a batch and the execution of any cached Transact-SQL statements. When specifying a value for count, the cached statements will be executed count times, as a single batch.
:r < filename >
Parses additional Transact-SQL statements and
sqlcmd commands from the file specified by <
filename>**into the statement cache.
If the file contains Transact-SQL statements that are not followed by GO, you must enter GO on the line that follows :r.
The file will be read and executed after a batch terminator is encountered. You can issue multiple :r commands. The file may include any
sqlcmd command. This includes the batch terminator GO.
Lists the locally configured servers and the names of the servers broadcasting on the network.
:Connect server_name[\instance_name] [-l timeout] [-U user_name [-P password]]
Connects to an instance of SQL Server. Also closes the current connection.
|n>0||wait for n seconds|
The SQLCMDSERVER scripting variable will reflect the current active connection.
If timeout is not specified, the value of the SQLCMDLOGINTIMEOUT variable is the default.
If only user_name is specified (either as an option, or as an environment variable), the user will be prompted to enter a password. This is not true if the SQLCMDUSER or SQLCMDPASSWORD environment variables have been set. If neither options nor environment variables are provided, Windows Authentication mode is used to login. For example to connect to an instance,
instance1, of SQL Server,
myserver, by using integrated security you would use the following:
To connect to the default instance of
myserver using scripting variables, you would use the following:
:setvar myusername test
:setvar myservername myserver
:connect $(myservername) $(myusername)
[:] !!< command>
Executes operating system commands. To execute an operating system command, start a line with two exclamation marks (!!) followed by the operating system command. For example:
:XML [ON | OFF]
For more information, see "XML Output Format," later in this topic
sqlcmd commands together with a short description of each command.
sqlcmd input files can be specified with the -i option or the :r command. Output files can be specified with the -o option or the :Error, :Out and :Perftrace commands. The following are some guidelines for working with these files:
:Error, :Out and :Perftrace should use separate <
filename>. If the same <
filename> is used, inputs from the commands may be intermixed.
If an input file that is located on a remote server is called from
sqlcmdon a local computer and the file contains a drive file path such as :out c:\OutputFile.txt. The output file will be created on the local computer and not on the remote server.
Valid file paths include: C:\<
filename>** and "C:\Some Folder\<
file name>**". If there is a space in the path, use quotation marks.
sqlcmdsession will overwrite existing files that have the same names.
sqlcmd prints any informational message that are sent by the server. In the following example, after the Transact-SQL statements are executed, an informational message is printed.
At the command prompt, type the following:
At the sqlcmd prompt type:
When you press ENTER, the following informational message is printed: "Changed database context to 'AdventureWorks2012'."
sqlcmd first prints a column header that contains the column names specified in the select list. The column names are separated by using the SQLCMDCOLSEP character. By default, this is a space. If the column name is shorter than the column width, the output is padded with spaces up to the next column.
This line will be followed by a separator line that is a series of dash characters. The following output shows an example.
sqlcmd. At the
sqlcmd command prompt, type the following:
SELECT TOP (2) BusinessEntityID, FirstName, LastName
When you press ENTER, the following result set is retuned.
BusinessEntityID FirstName LastName
---------------- ------------ ----------
285 Syed Abbas
293 Catherine Abel
(2 row(s) affected)
BusinessEntityID column is only 4 characters wide, it has been expanded to accommodate the longer column name. By default, output is terminated at 80 characters. This can be changed by using the -w option, or by setting the SQLCMDCOLWIDTH scripting variable.
XML output that is the result of a FOR XML clause is output, unformatted, in a continuous stream.
When you expect XML output, use the following command:
To set the XML mode off, use the following command:
The GO command should not appear before the XML OFF command is issued because the XML OFF command switches
sqlcmd back to row-oriented output.
XML (streamed) data and rowset data cannot be mixed. If the XML ON command has not been issued before a Transact-SQL statement that outputs XML streams is executed, the output will be garbled. If the XML ON command has been issued, you cannot execute Transact-SQL statements that output regular row sets.
Use the following practices to help maximize security and efficiency.
Use integrated security.
-Xin automated environments.
Secure input and output files by using appropriate NTFS file system permissions.
To increase performance, do as much in one
sqlcmdsession as you can, instead of in a series of sessions.
Set time-out values for batch or query execution higher than you expect it will take to execute the batch or query.
