    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.

    SELECT 'Spark' LIKE ALL ('_park', '%ark')
    -- True
