Re: Datatype misrepresentation DTS with SQL Server

Thanks, Tom. That looks promising, but unfortunately I don't have the
tools to recompile. I guess there's no magic configuration file that
would allow me to override this built-in type-mapping, eh?

Any chance someone else has run into this problem found a workaround
that doesn't involve customizing the code? I'd be satisfied with
something kludgy, as long as it could be reliably automated. <g>

You could try hacking the source code of the PG ODBC driver.  I note
this in pgtypes.c:

            /* Change this to SQL_BIGINT for ODBC v3 bjm 2001-01-23 */
        case PG_TYPE_INT8:
            return SQL_CHAR;

Don't know whether DTS will actually recognize SQL_BIGINT, but it's
worth a try.  SQL_NUMERIC could be worth trying too, if BIGINT fails.
