Transact-SQL syntax conventions

Syntax

sp_altermessage
    [ @message_id = ] message_id
    , [ @parameter = ] N'parameter'
    , [ @parameter_value = ] 'parameter_value'
[ ; ]

Arguments

[ @message_id = ] message_id

The error number of the message to alter from sys.messages. @message_id is int, with no default.

[ @parameter = ] N'parameter'

Used with @parameter_value to indicate that the message is to be written to the Microsoft Windows application log. @parameter is sysname, with no default.

@parameter must be set to WITH_LOG or NULL. If @parameter is set to WITH_LOG or NULL, and the value for @parameter_value is true, the message is written to the Windows application log. If @parameter is set to WITH_LOG or NULL and the value for @parameter_value is false, the message isn't always written to the Windows application log, but might be written depending upon how the error was raised.

If a message is written to the Windows application log, it is also written to the Database Engine error log file.

If @parameter is specified, @parameter_value must also be specified.

[ @parameter_value = ] 'parameter_value'

Used with @parameter to indicate that the error is to be written to the Microsoft Windows application log. @parameter_value is varchar(5), with no default.

  • If true, the error is always written to the Windows application log.
  • If false, the error isn't always written to the Windows application log, but might be written depending upon how the error was raised.

If @parameter_value is specified, @parameter must also be specified.

Return code values

0 (success) or 1 (failure).

Result set

None.

Remarks

The effect of sp_altermessage with the WITH_LOG option is similar to that of the RAISERROR WITH LOG parameter, except that sp_altermessage changes the logging behavior of an existing message. If a message is altered to be WITH_LOG, it is always written to the Windows application log, regardless of how a user invokes the error. Even if RAISERROR is executed without the WITH_LOG option, the error is written to the Windows application log.

System messages can be modified by using sp_altermessage.

Permissions

Requires membership in the serveradmin fixed server role.

Examples

The following example writes the existing message 55001 to the Windows application log.

EXEC sp_altermessage 55001, 'WITH_LOG', 'true';
GO
