For the query with 2 a's in each name cant we just give e_name like '%a%a%' ?

[sachinpujari]

Thank You Sir. Your Explanatio is superb....

[unnatijaswani]

For query no 20, it did not ask u to add 10 or 20 to no, it said if n_id is 0, then n_id=10, elseif n_id=1, then n_id=20. Pls chk it once again.
