SYMPTOMS
SQLDescribeCol always returns pcbColDef = 255 for a scalar function projected column of SQL_VARCHAR data type of defined length.

This problem occurs with all 16- and 32-bit Access drivers. This does not happen with SQL Server drivers.

Microsoft has confirmed this to be a problem in the Access Driver versions 2.00.2317 and 3.00.2106. We are researching this problem and will post new information here in the Microsoft Knowledge Base as it becomes available.

To reproduce this problem:


 * The 'name' field is of type SQL_VARCHAR of defined length.

SQLDescribeCol for column 2 returns pcbColDef = 255. also


 * Select name, {fn UCASE(name)} from oof

SQLDescribeCol for column 2 returns pcbColDef = 255.
