Re: MS Access & foreign encoding bug - Mailing list pgsql-odbc

I have some more informations that may help you: the problem in the driver since version 209 only appears in Access
whenusing a "pass-through query", a query sent directly to the database, just as we would type it in PGAdmin. The same
query,but through "linked tables", is ok. 

I was not able to find out what in the record makes Access pass-through query fail, but it appears to be linked to text
fieldsin the database. I have a specific record, filled with some multiline text, that cannot be retreived with a
pass-throughquery. If I change some characters in the text, it works sometimes, but sometimes it still fails. If I copy
andpast the text twice in the text field, it suddenly works too... There is apprently no specific characters string or
stringlength that bugs, weird!

Objet : [ODBC] MS Access & foreign encoding bug

Hi,

I have just tested PSQLODBC-libpq version 8.01.00.02 with MS Access, and until now, I have not noticed anything special
comparedto the non-libpq version. Thanks to all who support the driver. 

A bug has appeared with version 209 of the driver, and has not been corrected since then. It is apparently linked to
foreignencodings. 
Version 208 of the driver does not suffer from that at all. That's the one I use for production at the moment.

The libpq version has the same problem. When opening certain records, MS Access fails with error '2467': the expression
referencesan object that was closed or deleted. Or sometimes: "You tried to affect the NULL value to a variable that is
notof type Variant." 

Here is some log output. Tell me if there is any specific test I can do for you, in order to track down the bug.

Regards,

Philippe
