Re: Auto Increment Column
Hi Raj! What is a condition of rows numbering? Enumerating - it is kind of ordering. Does table has some order? Well defined problem is a half solution.

Re: Change table column's data type
Hi, Jim.
I'm afraid is not the end .
You didn't investigate a case with prejoin-projections Its a long story and bad idea (imho) modify column data type on production system (there are may be segments, buddy/prejoin-projections).

Re: Change table column's data type
Hi, Beck.
If each Monday you need to change data type for some column so try to define data type "wide" as much it possible, i.e. instead INTEGER or FLOAT define NUMERIC type or VARCHAR, while in queries do casing. IMHO its a better solution than modifying column data type.
