[ ; ]
Arguments
Important
Arguments for extended stored procedures must be entered in the specific order as described in the Syntax section. If the parameters are entered out of order, an error message occurs.
[ @user_defined_event_id = ] user_defined_event_id
A parameter defined by the user and recorded in the user_defined_event_id column of the audit log. @user_defined_event_id is smallint.
[ @succeeded = ] succeeded
A parameter passed by user to indicate whether the event was successful or not. This value appears in the succeeded column of the audit log. @succeeded is bit.
[ @user_defined_information = ] N'user_defined_information'
The text defined by the user and recorded in the new user_defined_event_id column of the audit log. @user_defined_information is nvarchar(4000).
Return code values
0 (success) or 1 (failure).
Failures are caused by incorrect input parameters, or failure to write to the target audit log.
Remarks
When the USER_DEFINED_AUDIT_GROUP is added to either a server audit specification or a database audit specification, the event triggered by sp_audit_write is included in the audit log.
Permissions
Requires membership in the public database role.
