Hi Team,

I have 3 tables one with 84k records , one with 20 records and another one with 1000 records and am fetching few columns from all these tables with some conditions . It’s taking forever and in explain plan it is having nested loop and cost is high. I have created index also for these tables but still it’s taking sequential scan.

Any suggestions

Thanks & regards

Firthouse

It's impossible to help with that few details.  See

include.
