Subj:   Re: Reduce the likelihood of a Full Table Scan
 
From:   Gregg, William

Hi Sugesh -- some things to consider when U review the answers the Forum community offers:

1) Teradata is built to do tables scans; FTS are done quickly;

2) The Optimizer often ignores secondary indices in favor of table scans;

3) Teradata is all about parallel processing.


Good Luck.

Bill Gregg, Teradata
