Problem with Request. SQL Column Errors

'where pageId='.quote(pageId)in order for the full Hashed Id to be queried properly.
If you code or use an installed Macro, be aware of this distinction. If you find an error like that in the main code, do check and submit a bug report exactly what module and error message.
This is just one of the reasons that you shouldn't try to mix and match 5.x and 6.x macros and wobjects.
