It can contain special pattern-matching characters: * `%` matches zero or more characters. * `_` matches exactly one character. * **esc_char** Specifies the escape character. The default escape character is `\`. * **regex_pattern** Specifies a regular expression search pattern to be searched by the `RLIKE` or `REGEXP` clause. ### Examples ```sql CREATE TABLE person (id INT, name STRING, age INT); INSERT INTO person VALUES (100, 'John', 30), (200, 'Mary', NULL), (300, 'Mike', 80), (400, 'Dan', 50), (500, 'Evan_w', 16); SELECT * FROM person WHERE name LIKE 'M%'; +---+----+----+ | id|name| age| +---+----+----+ |300|Mike| 80| |200|Mary|null| +---+----+----+ SELECT * FROM person WHERE name LIKE 'M_ry'; +---+----+----+ | id|name| age| +---+----+----+ |200|Mary|null| +---+----+----+ SELECT * FROM person WHERE name NOT LIKE 'M_ry'; +---+------+---+ | id| name|age| +---+------+---+ |500|Evan_W| 16| |300| Mike| 80| |100| John| 30| |400| Dan| 50| +---+------+---+ SELECT * FROM person WHERE name RLIKE 'M+'; +---+----+----+ | id|name| age| +---+----+----+ |300|Mike| 80| |200|Mary|null| +---+----+----+ SELECT * FROM person WHERE name REGEXP 'M+'; +---+----+----+ | id|name| age| +---+----+----+ |300|Mike| 80| |200|Mary|null| +---+----+----+ SELECT * FROM person WHERE name LIKE '%\_%'; +---+------+---+ | id| name|age| +---+------+---+ |500|Evan_W| 16| +---+------+---+ SELECT * FROM person WHERE name LIKE '%$_%' ESCAPE '$'; +---+------+---+ | id| name|age| +---+------+---+ |500|Evan_W| 16| +---+------+---+ ``` ### Related Statements * [SELECT](sql-ref-syntax-qry-select.html) * [WHERE Clause](sql-ref-syntax-qry-select-where.html)
