Subject: SQL - select data available in index
Posted: Mon Jun 26, 2017 1:30 am (GMT 5.5)
I read somewhere in my email trail with local
DBAs that if selected colums in a query are available
in indexed columns, the query is faster.
Any idea how much faster it makes a select query if all selected colums are available in indexed compinent vs some could not available in indexed components
Thanks
