Re: Access violation (0xC0000005) in PSQLODBC35W.DLL when calling SQLDescribeColW

Hi Hiroshi

this build has another problem

::SQLTables no longer returns the table name at all (empty string).

So I can't test any further, since I require this for all my startup
code, type retrieval etc (for a column of a table def).

Regards

Adrien
