Re: match columns on insert sub select

Looks like the only way is to write a script reading all_tab_columns for both tables and execute dynamic sql with the matching results from that. Not sure if it's worth it. Thanks for the responses. -Dan

I agree with you that it would be very useful.

I don't understand Erik's objection about adding a column in source table.
If that column is not in dest table, it's simply not copied.

The objection should be instead on dropping a column in source table. But in this case simply NULL may be inserted.

So, for me it would be just very useful. I don't see any counter-indication in such an instruction.
