REGEXP_CONTAINS

Returns true if a piece of text is a partial match for the regular expression.

Sample usage

REGEXP_CONTAINS(Page, 'home')

Syntax

REGEXP_CONTAINS(X, regular_expression)

Parameters

  • X - a field or expression to evaluate.
  • regular_expression - a regular expression.

Returns

The REGEXP_CONTAINS function returns boolean values.

Examples

Example formula Input Output
REGEXP_CONTAINS(Field, 'A') ABC123 true
REGEXP_CONTAINS(Field, 'A.*') ABC123 true
REGEXP_CONTAINS(Field, 'AC') ABC123 false

Notes

REGEXP_CONTAINS differs from the similar REGEXP_MATCH function, which will only match the entire value by default. Thus, REGEXP_CONTAINS(field,"pattern") is functionally equivalent to REGEXP_MATCH(field,".*pattern.*).

Looker Studio uses the RE2 expression syntax. For more details, see Regular Expressions in Looker Studio.

Note that patterns containing escape characters such as \ may require additional escaping in Looker Studio, which can be avoided with the use of raw string literals.
