MySQL NOT LIKE operator
NOT LIKE operator
MySQL NOT LIKE is used to exclude those rows which are matching the criterion followed by LIKE operator.
Syntax:
expr NOT LIKE pat [ESCAPE 'escape_char']
- Pattern matching using SQL simple regular expression comparison. Returns 1 (TRUE) or 0 (FALSE). If either expr or pat is NULL, the result is NULL.
- The pattern need not be a literal string. For example, it can be specified as a string expression or table column.
- Per the SQL standard, LIKE performs matching on a per-character basis, thus it can produce results different from the = comparison operator.
- LIKE operator uses WILDCARDS (i.e. %, _) to match the pattern. This is very useful to check whether a particular character or string is present in the records.
% is used to match any number of characters, even zero characters.
_ is used to match exactly one character.
To test for literal instances of a wildcard character, precede it by the escape character. If you do not specify the ESCAPE character, “\” is assumed.
\% is used to match one "%" character.
\_ Matches one "_" character
MySQL Version: 5.6
Example: MySQL NOT LIKE operator with (%) percent
The following MySQL statement excludes those rows from the table author, having the 1st character of aut_name ‘W’.
Code:
SELECT aut_name, country
FROM author
WHERE aut_name NOT LIKE 'W%';

Example : MySQL NOT LIKE operator with ( _ ) underscore
The following MySQL statement excludes those rows from the table author having the country name like the above pattern as specified with LIKE operator.
Code:
SELECT aut_name, country,home_city
FROM author
WHERE country NOT LIKE 'U_A' and country NOT LIKE 'C__a_a';
