srv_rpcdb (Extended Stored Procedure API)

重要提示：
后续版本的 Microsoft SQL Server 将删除该功能。请不要在新的开发工作中使用该功能，并尽快修改当前还在使用该功能的应用程序。 Use CLR integration instead.

Returns the database name component for the current remote stored procedure.

语法

DBCHAR * srv_rpcdb (
SRV_PROC * srvproc,int *len );

Arguments

• srvproc
  Is a pointer to the SRV_PROC structure that is the handle for a particular client connection. The structure contains information the Extended Stored Procedure API library uses to manage communication and data between the application and the client.

• len
  Is a pointer to an int variable that receives the length of the database name. If len is NULL, the length of the database name is not returned.

Returns

A DBCHAR pointer to the null-terminated string for the database name part of the current remote stored procedure. If there is no current remote stored procedure, NULL is returned and the len parameter is set to - 1.

备注

This function returns only the database component of the remote stored procedure object name. It does not include the optional specifiers for owner, remote stored procedure name, and remote stored procedure number.

安全说明：
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.
