NOT LIKE

Description

The NOT LIKE operator is used in a WHERE clause to search for a specified pattern in a column.

There are two wildcards often used in conjunction with the NOT LIKE operator:

  • The percent sign (%) represents zero, one, or multiple characters.
  • The underscore sign (_) represents one, single character.

Syntax

> SELECT column1, column2, ...
FROM table_name
WHERE columnN NOT LIKE pattern;

Examples

> create table t1 (a char(10));
> insert into t1 values('abcdef');
> insert into t1 values('_bcdef');
> insert into t1 values('a_cdef');
> insert into t1 values('ab_def');
> insert into t1 values('abc_ef');
> insert into t1 values('abcd_f');
> insert into t1 values('abcde_');
> select * from t1 where a not like 'a%';
+--------+
| a      |
+--------+
| _bcdef |
+--------+
> select * from t1 where a not like "%d_\_";
+--------+
| a      |
+--------+
| abc_ef |
