FIX: SQL Server ODBC Driver Generates Error When Executing a Stored Procedure on SQL Server 2000

View products that this article applies to.

This article was previously published under Q286359

SYMPTOMS

An application that uses the Open Database Connectivity (ODBC) application programming interface (API) to call a SQL Server 2000 stored procedure that has a return value with the SQLExecDirect() API function and open a cursor on the resulting table may return the following errors:

szSqlState = "42000", *pfNativeError = 170, *pcbErrorMsg = 81 MessageText = "[Microsoft][ODBC SQL Server Driver][SQL Server]Line 1: Incorrect syntax near '?'."

szSqlState = "42000", *pfNativeError = 16945, *pcbErrorMsg = 75 MessageText = "[Microsoft][ODBC SQL Server Driver][SQL Server]The cursor was not declared."

CAUSE

Before the SQL Server ODBC driver sends the command to the SQL Server, it restructures the ODBC call syntax to the SQL Server sp_opencursor command syntax. In the process of restructuring the command, the driver does not put a space after the name of the stored procedure. For example, calling this stored procedure causes the SQL Server ODBC driver to generate the following sp_cursoropen call.

Table Schema and Stored Procedure

create table testtable
(f1 integer)
go
create proc testproc
@p1 integer
as
select * from testtable where f1 = @p1
return 2

ODBC Call Syntax

{? = call testproc(?)}

Resulting Call to SQL Server 2000

exec sp_cursoropen @P1 output, N' EXEC @P1=testproc@P2? ', @P2 output, @P3 output, @P4 output, N'@P1 int OUTPUT,@P2 int', @P5 output, 1

Note that the second parameter and the name of the stored procedure do not have a space between them; this causes the syntax error.
