Re: Adding a New Column Specifically In a Table

I think it's incorrect to expect a query to return column in any specific order if you do something like "select * from...". You may see columns returned in the order you created them, but I don't believe it's guaranteed. If you want a specific order, then.... "select col1, col3, col5, col2, ...".

Ah sadly I just found this after I pressed 'send' and realized
PostgreSQL doesn't support it...that sucks :(
