Hi Tino, Yes, I know it's not very standard and certainly not in the spirit of relational db's > If you want to have a given ordering, why not just specify your > column names in that order in your statements?

The frondend functions are made so they accept any query ("select *") and find out or themselves how to handle things. > I dont think the overhead in implementing such a rarely needed > feature isnt worth it. We need a lot more other things ;-) I agree. Only I think this wouldn't require new functionality, I have a gut feeling that this is possible as it is. Now only find out how :) I'll have a look at the system tables (that's where the answer must be) but maybe someone who has done this can save me the time...
