You can exclude a certain row from sql query using '<>' or '!=' clause.
For example, if you want to exclude the row in the result with user_id => 1 from the table 'poll', following query will give you the desired result.
SELECT * FROM `poll` WHERE user_id <> 1
If the data type of
idis String you must use
SELECT * FROM `poll ` WHERE user_id <> '1'
Note: In MySQL, you can also use != rather than <> but <> is ANSI and more portable.
