As long as you stick to either (a) or (b) you will be okay ... if you
mix-n-match that will make Oracle do more work.

Subject: Does the case of an Oracle query statement affect query performance?Hi,Pardon me for such a naive question, coz I am a novice when it comes to Oracle. This is basically got to do with how Oracle parses a query.Consider the following queries:a) SELECT column1, column2 FROM table WHERE column0 = 5;b) SELECT COLUMN1, COLUMN2 FROM TABLE WHERE COLUMN0 =5;Scenario 1: I use the naming convention a) for ALL my queriesScenario 2: I use the naming convention b) for ALL my queriesWill there be any difference in the execution time of the same queries in Scenario 1 vs 2?Thanx in advance,Shantanu.--------------
