Hi Dore,

I'm not sure, that I understand your advice, could you please elaborate a little more? This table (I mean the target shell) has lots of compound indexes.

TIA

Then we need to place this records into Database with predefined structure, indexes, etc. So, firstly it prepares a shell Database and a table and then uses Append from command (runs DeNull program in between). This operation takes already ~15 min. and it's not finished yet. What can you suggest to optimize it?

If it's not broken, fix it until it is.
