Hello, I use WinZEOS Delphi components. I want to create a user using ExecSQL method of TZPgSqlQuery component. When I call this method, the exception is raised: 'CREATE USER: may not be called in a transaction block'. The component seems to begin an implicit BEGIN / END block when ExecSQL method is called. So the question is: 1. Is there any way to avoid calling of BEGIN / END in these components, or 2. Is there any way to create a user inside a transaction block? Direct writes to pg_shadow don't work too, I have tried. Thanks, Alex Bolenok.
