Hello.
I would like to know if Oracle distinguishes SQL statements based on case.
For eg. will the following statements compiled separately within Oracle?
SELECT * FROM USER
and
select * from user
What will be the performance impact?
Thanks,
Kris

Both the statements get diffent parse-codes.
so
if you execute statement1 and let the parsecode is xxa1.
if u execute the same statement again, oracle will NOT parase the statement.
but when you execute the statement2 there will a full parse and another parse-code is generated.
