I would like to use PostgreSQL through ODBC with Delphi 5. According to the Postgre documentation the IN operator exists, however I get the "Capability not supported!" error message after issuing the following SQL command:
SELECT CsoportAzonKod FROM Felhaszn_Csoport
WHERE FelhAzonKod=1 AND CsoportAzonKod IN
(SELECT CsoportAzonKod FROM Menu_Csoport
WHERE MenuAzonKod=1)
(ODBC version 6.40.00.07 - written by Insight Distribution Systems.)
Why?
Thank you
