srv_paramtype (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 data type of a remote stored procedure call parameter.

语法

int srv_paramtype (
SRV_PROC *
srvproc
,
int
n 
);

Arguments

• srvproc
  Is a pointer to the SRV_PROC structure that is the handle for a particular client connection (in this case, the handle that received the remote stored procedure call). The structure contains information the Extended Stored Procedure API library uses to manage communication and data between the application and the client.

• n
  Indicates the number of the parameter. The first parameter is 1.

Returns

A token value for the data type of the parameter. For information about data types, see Data Types (Extended Stored Procedure API). If there is no nth parameter or if there is no remote stored procedure, it returns - 1.

This function returns the following values, if the parameter is one of the Microsoft SQL Server 2005 data types.

备注

When a remote stored procedure call is made with parameters, the parameters can be passed either by name or by position (unnamed). If the remote stored procedure call is made with some parameters passed by name and some passed by position, an error occurs. The SRV_RPC handler is still called, but it appears as if there were no parameters and srv_rpcparams returns 0.

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.
