FIX: Cannot Insert BLOB Data Larger Than 128k w/ SQLSetParam

• Microsoft Open Data Base Connectivity, version 2.5
• Microsoft SQL Server, versions 4.21a

SYMPTOMS

When you connect to SQL Server version 4.21a and use the SQLSetParam function to insert image or text data where the total size (such as the cbcoldef argument for SQLSetParam) is larger than 128K, you will receive the following error message from the SQL Server driver:

   [Microsoft][ODBC SQL Server Driver][SQL Server] Memory request failed
   because more than 64 pages are required to run the query in its
   present form. The query should be broken up into shorter queries if
   possible[#703].

CAUSE

This problem only occurs when the SQLSetParam function is used.

WORKAROUND

Use the ODBC version 2.0 function SQLBindParameter instead of SQLSetParam.

STATUS

Microsoft has confirmed this to be a problem in the SQL Server Driver version 2.50.121. This problem was corrected in Service Pack 1 for SQL Server version 6.0. For more information, contact your primary support provider.

MORE INFORMATION

Before you connect a SQL Server Driver version 2.50.121 or later to SQL Server version 4.21a, make sure that the INSTCAT.SQL file that ships with the driver has been executed on the server. The INSTCAT.SQL script upgrades the catalog stored procedures used by the driver.
