Description:
Driver returns SQL_TRUE for SQL_API_SQLPROCEDURECOLUMNS for SQLGetFunctions

    SQLUSMALLINT nSupported = SQL_FALSE;
    SQLRETURN rc = SQLGetFunctions( m_hdbc, nFunctionID, &nSupported );

indicating that is supports SQLProcedureColumns but you you call this api you get an error saying that driver does not support this yet
SQLProcedureColumns ]Driver doesn't support this yet

How to repeat:
1 Call SQLGetFunctions with SQLPROCEDURECOLUMNS 
2 you get SQL_TRUE indicating driver supports calling SQLProcedureColumns
3 call SQLProcedureColumns, you get an error saying driver does not support this yet

Suggested fix:
Return SQL_FALSE for SQLGetFunctions with SQLPROCEDURECOLUMNS

Yes, we shouldn't claim to support SQLProcedureColumns(). It's unlikely we'll support it in 3.51 due to the difficulty of getting this information from the server. It will probably be added to 5.0 or a later release.

The fix was committed to the source repository, and will be in the next release (3.51.15).

Thanks for the bug report.

A note has been added to the 3.51.15 changelog.

This behavior is changing again in 3.51.24 because it causes problems for ADO applications. See Bug #33298.

SQLProcedureColumns() now returns an empty result set and SQL_SUCCESS_WITH_INFO, with an explanation of why there is no data.
