But!...

Please remember that "getting rid of table scans" is not necessarily a smart goal. Oracle only provides a few ways to join tables:

Each is suitable in its place. If you eliminate all full-table scans, then the only one of these that you have left is nested loops. In certain circumstances, a nested loops execution plan can motivate run times of hundreds of hours.

Hi List,

While reading statpack book, came across a script which is using stats$sysstat to estimate FTS. The statistic# used is 140 which is 'transaction lock foreground requests' (Ver.8.1.7.4)

The value for this statistic# in v$sysstat is zero. Is there a way to find
out FTS from v$sysstat ? If yes, what is the statistic# name ?

Thanks,
~Dilip
