How to remove duplicates from table using SQL query

Question

uuuu       eee          m    s
iiii       iii          f    s

Answer 1

I know this is old post, but recently I tested a solution and want to share if any one can find my solution helpful -

CREATE TABLE tmpTable LIKE yourTable; insert into tmpTable (col1, col2 ... colN) SELECT distinct col1, col2 ... colN FROM yourTable WHERE 1; drop table yourTable; RENAME TABLE tmpTable TO yourTable;

Please note, insert into statement may execute without primary key.

Thanks.
