srv_paramtype

Returns the data type of a remote stored procedure call parameter.

Important This Open Data Services function or macro is only supported in Microsoft® SQL Server™ version 7.0 for backward compatibility. It has been superseded by the srv_paraminfo function.

For more information about Open Data Services functions or macros supported for backward compatibility, see Open Data Services (Level 3).

Syntax

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 ODS Library uses to manage communication and data between the Open Data Services server 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. You can get a readable description for the value by using srv_symbol. For information about a list of data types, see Data Types. If there is no nth parameter or if there is no remote stored procedure, returns - 1.

This function returns the following values, if the parameter is one of the new SQL Server 7.0 data types.

Remarks

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.
