Subj:   Re: Why a Query with Huge IN List Fails
From:   sughesh iyyani


Try to use BETWEEN...AND... It will run much faster than IN.

Teradata should take the column value of each record and check whether it matches with value mentioned in the In clause list.

This is the reason IN is working slower.
