LIKE

Tests whether an expression matches one or more patterns. Comparisons are case-sensitive.

Syntax

expression [ NOT ] LIKE pattern → boolean

• expression: The expression to compare.

• NOT: A keyword that inverts the return value.

• pattern: The pattern that is compared to the expression.

Examples

LIKE example

SELECT 'pancake' LIKE '%cake'
-- True

LIKE example

SELECT 'pancake' NOT LIKE '%cake'
-- False

expression [ NOT ] LIKE pattern ESCAPE escape_character → boolean

• expression: The expression to compare.

• NOT: A keyword that inverts the return value.

• pattern: The pattern that is compared to the expression.

• escape_character: Putting escape_character before a wildcard in pattern makes LIKE treat the wildcard as a regular character when it appears in expression.

Examples

LIKE example

SELECT '50%_Off' LIKE '%50!%%' ESCAPE '!'
-- True

LIKE example

SELECT '%SalesData%/Users/Jane' NOT LIKE '/%SalesData/%//Users/%' ESCAPE '/'
-- False

expression [ NOT ] LIKE { ANY | SOME | ALL } ( [ pattern [, …] ] ) → boolean

• expression: A STRING expression.

• NOT: A keyword that inverts the return value.

• ANY or SOME or ALL: Keywords indicating whether the expression must match at least one pattern or must match all patterns.

• pattern: One or more STRING expressions.
