[TYPO3] MySQL LAST_INSERT_ID() returns 0, different connection???

[Andreas Förthner]

Hi list,

I just tried to fill a table and its mm-table with the right ids. I 
insert the values in the main table and then I try to insert the 
mm-relation, for that reason I need the id of the inserted record. I 
tried that with the LAST_INSERT_ID() function in mysl, but it seems to 
return always 0. As far as I know it only will return the id if the two 
  insert-statements are in the same database connection... Is it 
possible that TYPO3 opens an new connection for each query?

Does anybody know a solution for that problem? How do you fill mm-tables 
usually?

Thank you for your help...

Regards

Andreas
