Have you read the documentation as I suggested? No, not really. That's why my answers don't help.
probably there is not so much doc and probably there are not enought examples and the last book is 8 years old and doesn't cover what I need.
The documentation for the SQL module is on the Wiki and in the doc/ directory. It documents *exactly* how the module works, include the "!=" and ":=" operator. I'm sorry you feel like I'm not helping you. But this *is* documented, and it is *not* rude to ask you to read the documentation. *All* of your questions and confusion would be addressed by reading the documentation. Please read it. If you have any questions about it, ask. Alan DeKok.
