FIX: Sp_cursoropen Error With More Than One Parameter Marker

ID: Q154966

The information in this article applies to:

Microsoft SQL Server version 6.5

SYMPTOMS

When you use server side cursors, SQL Server Driver invokes the extended stored procedure Sp_cursoropen with incorrect parameters when the following conditions are met:

The number of parameter markers in the WHERE clause of a SELECT statement are more than one.

The parameter markers correspond to CHAR or VARCHAR datatypes.

The network packet size is set to 512 bytes in the server configuration/options.

In addition, SQL Server Driver generates the following error message:

szSqlState = "37000", *pfNativeError = 16903,
szErrorMsg="[Microsoft][ODBC SQL Server Driver][SQL Server]
sp_cursoropen procedure called with incorrect number of parameters".

The following error message appears if any further activity occurs on the client side:

Communication link failure.

WORKAROUND

Set the Network Packet Size greater than 512 bytes in Server Configuration/Options using Sp_configure.

STATUS
