Обсуждение: Should/does SQLForeignKeys work (8.03.02)?

Hi,

I am trying to retrieve the foreign keys of/to a PostgreSQL table
(PostgreSQL ODBC 8.03.02, PostgreSQL 8.3.3, unixodbc 2.2.11) using ODBC.
But whatever I try I do not get any results.

I assume that if I do

SQLForeignKeys(hstmt,
         NULL, 0,            /* Primary catalog */
         NULL, 0,            /* Primary schema */
         szTable, SQL_NTS,   /* Primary table */
         NULL, 0,            /* Foreign catalog */
         NULL, 0,            /* Foreign schema */
         NULL, 0);           /* Foreign table */

I should get all the foreign keys TO this table FROM another table.

Otherwise, doing

SQLForeignKeys(hstmt,
         NULL, 0,             /* Primary catalog */
         NULL, 0,             /* Primary schema */
         NULL, 0,             /* Primary table */
         NULL, 0,             /* Foreign catalog */
         NULL, 0,             /* Foreign schema */
         szTable, SQL_NTS);   /* Foreign table */

should get me all the foreign keys FROM this table TO another table.

BTW: I have tried it with non-null catalogs and schemas also.

Is that correct, and should it work?

TIA

Seems the server side implementation of foreign keys was changed in 8.3
  and 8.3.02 ODBC drivers didn't know it.
I beleive the bug was fixed in 8.3.0201.

So ... when will that be released?

I would talk with Hiroshi Saito about the next release.
Anyway I have not been able to commit changes to psqlodbc
for some days because the server responds with the message
 "waiting for anonymous's lock in /cvsroot/psqlodbc/psqlodbc".

Thanks.
