Øystein Grøvlen Sir, hope will expect answer from your end.
Distinct clause issue having only in MySQL database or some other database as well?. I have worked on Oracle, Db2, MS Sql SERVER i have't faced issue in these databases. Strange issue in MySQL databases, wasn't expected.
I can write subselect query instead of left joins , will try to modify my queries. Is Cardinality length causes issues for performance?.
