Creates a removable media database. Creates three or more files (one for the system catalog tables, one for the transaction log, and one or more for the data tables) and places the database on those files.
|Applies to: SQL Server (SQL Server 2008 through current version).|
sp_create_removable [ @dbname = ] 'dbname', [ @syslogical= ] 'syslogical', [ @sysphysical = ] 'sysphysical', [ @syssize = ] syssize, [ @loglogical = ] 'loglogical', [ @logphysical = ] 'logphysical', [ @logsize = ] logsize, [ @datalogical1 = ] 'datalogical1', [ @dataphysical1 = ] 'dataphysical1', [ @datasize1 = ] datasize1 , [ @datalogical16 = ] 'datalogical16', [ @dataphysical16 = ] 'dataphysical16', [ @datasize16 = ] datasize16 ]
[ @dbname= ] 'dbname'
Is the name of the database to create for use on removable media. dbname is sysname.
[ @syslogical= ] 'syslogical'
Is the logical name of the file that contains the system catalog tables. syslogical is sysname.
[ @sysphysical= ] 'sysphysical'
Is the physical name. This includes a fully qualified path, of the file that holds the system catalog tables. sysphysical is nvarchar(260).
[ @syssize= ] syssize
Is the size, in megabytes, of the file that holds the system catalog tables. syssize is int. The minimum syssize is 1.
[ @loglogical= ] 'loglogical'
Is the logical name of the file that contains the transaction log. loglogical is sysname.
[ @logphysical= ] 'logphysical'
Is the physical name. This includes a fully qualified path, of the file that contains the transaction log. logphysical is nvarchar(260).
[ @logsize= ] logsize
Is the size, in megabytes, of the file that contains the transaction log. logsize is int. The minimum logsize is 1.
[ @datalogical1= ] 'datalogical'
Is the logical name of a file that contains the data tables. datalogical is sysname.
There must be from 1 through 16 data files. Typically, more than one data file is created when the database is expected to be large and must be distributed on multiple disks.
[ @dataphysical1= ] 'dataphysical'
Is the physical name. This includes a fully qualified path, of a file that contains data tables. dataphysical is nvarchar(260).
[ @datasize1= ] 'datasize'
Is the size, in megabytes, of a file that contains data tables. datasize is int. The minimum datasize is 1.
0 (success) or 1 (failure)
If you want to make a copy of your database on removable media, such as a compact disc, and distribute the database to other users, use this stored procedure.
Requires CREATE DATABASE, CREATE ANY DATABASE, or ALTER ANY DATABASE permission.
To maintain control over disk use on an instance of SQL Server, permission to create databases is typically limited to a few login accounts.
Whenever certain operations are performed on a database, corresponding permissions are set on its data and log files. The permissions prevent the files from being accidentally tampered with if they reside in a directory that has open permissions.
|Operation on Database||Permissions Set on Files|
|Modified to add a new file||Created|
The following example creates the database
inventory as a removable database.
EXEC sp_create_removable 'inventory', 'invsys', 'C:\Program Files\Microsoft SQL Server\MSSQL13.MSSQLSERVER\MSSQL\Data\invsys.mdf' , 2, 'invlog', 'C:\Program Files\Microsoft SQL Server\MSSQL13.MSSQLSERVER\MSSQL\Data\invlog.ldf', 4, 'invdata', 'C:\Program Files\Microsoft SQL Server\MSSQL13.MSSQLSERVER\MSSQL\Data\invdata.ndf', 10;
