srv_message_handler (Extended Stored Procedure API)

중요:
Microsoft SQL Server의 이후 버전에서는 이 기능이 제거됩니다. 새 개발 작업에서는 이 기능을 사용하지 말고, 현재 이 기능을 사용하는 응용 프로그램은 가능한 한 빨리 수정하십시오. Use CLR integration instead.

Calls the installed Extended Stored Procedure API message handler. This function is usually used to call Microsoft SQL Server from an extended stored procedure to log an error (defined by the extended stored procedure) in the SQL Server error log file or the Microsoft Windows application log.

Arguments

• srvproc
  Is a pointer to the SRV_PROC structure that is the handle for a particular client connection. The srvproc parameter contains information that is used to manage communication and data between the application and the client.

• errornum
  Is an error number defined by the extended stored procedure. This number must be from 50,001 through 2,147,483,647.

• severity
  Is a standard SQL Server severity value for the error. This number must be from 0 through 24.

• state
  Is a SQL Server state value for the error.

• oserrnum
  Is the operating-system error number. This argument is ignored.

• errtext
  Is the description of the extended stored procedure error errornum.

• errtextlen
  Is the length of the extended stored procedure error string errtext.

• oserrtext
  Is the description of the operating-system error oserrnum. This argument is ignored.

• oserrtextlen
  Is the length of the operating-system error string oserrtext.

Returns

SUCCEED or FAIL.

주의

The srv_message_handler function enables an extended stored procedure to integrate with the centralized error logging and reporting features of SQL Server. SQL Server alerts can be established for events from extended stored procedures, and SQL Server Agent will monitor for these alert conditions.

If the error message is longer, it is truncated to 412 bytes.

보안 정보:
You should thoroughly review the source code of extended stored procedures, and you should test the compiled DLLs before you install them on a production server. For information about security review and testing, see this Microsoft Web site.
