Yeah I saw that after I sent the email but it's still dumb IMHO. We can either blame achaudhr or his/her boss. :-)

It's because the definition of the column in the dba_tables view does an lpad on the column to 5 characters... Look for ******* in the definition below...

This does not work:
select owner,table_name,cache from dba_tables where cache='Y';

This does:
select owner,table_name,cache from dba_tables where cache=' Y';

The datatype for the column from desc dba_tables is VARCHAR2(5).

So why would Oracle have leading spaces stored in a VARCHAR2 column?
