MySQL result resource problems

[Buschi]

I have got a problem with my local server. My scripts work without any problems on my internet server but if I try to test them offline I get errors wherever I try to get information from my SQL database. I allways get a warning message like this:

Warning: mysql_fetch_row(): supplied argument is not a valid MySQL result resource in <filename> on line <linenumber>

There is no problem using the database by comandline and all the other PHP commands work fine. Does anybody know how to fix this?

do you have the same username and pwd on the local machine that you have on the net server? db names are the same? How about host name?

Can you run the queries from the monitor command line ok?

No, I have a different username and pwd but I have also different versions of the scripts for offline an online where the database connection code is diffrent. And the queries I run in the scripts work in the command line like they should.
