This predicate also supports multiple patterns with quantifiers include `ANY`, `SOME` and `ALL`. ```sql [ NOT ] { LIKE searchpattern [ ESCAPE escchar ] | [ RLIKE | REGEXP ] regex_pattern } [ NOT ] { LIKE quantifiers ( search_pattern [ , ... ]) } ``` search_pattern* Specifies a string pattern to be searched by the `LIKE` clause. 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. quantifiers* Specifies the predicate quantifiers include `ANY`, `SOME` and `ALL`. `ANY` or `SOME` means if one of the patterns matches the input, then return true; `ALL` means if all the patterns matches the input, then return true. ```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| ++++ SELECT * FROM person WHERE name LIKE ALL ('%an%', '%an'); ++-+-+ | id|name| age| ++-+-+ |400| Dan| 50| ++-+-+ SELECT * FROM person WHERE name LIKE ANY ('%an%', '%an'); ++++ | id| name|age| ++++ |400| Dan| 50| |500|Evan_W| 16| ++++ SELECT * FROM person WHERE name LIKE SOME ('%an%', '%an'); ++++ | id| name|age| ++++ |400| Dan| 50| |500|Evan_W| 16| ++++ SELECT * FROM person WHERE name NOT LIKE ALL ('%an%', '%an'); ++-+-+ | id|name| age| ++-+-+ |100|John| 30| |200|Mary|null| |300|Mike| 80| ++-+-+ SELECT * FROM person WHERE name NOT LIKE ANY ('%an%', '%an'); +++-+ | id| name| age| +++-+ |100| John| 30| |200| Mary|null| |300| Mike| 80| |500|Evan_W| 16| +++-+ SELECT * FROM person WHERE name NOT LIKE SOME ('%an%', '%an'); +++-+ | id| name| age| +++-+ |100| John| 30| |200| Mary|null| |300| Mike| 80| |500|Evan_W| 16| +++-+ ```
