what I understand, if your have short table then index is not in use
(full table scan) but if you have large table then that index will be
used which has less no. of records like if in table if we have 1000
entries where deptno=10 and 1500 entries where sal>1000 then deptno
index will be in use.
Is it correct.............................Received on Wed May 31 2006 - 12:21:00 CDT
