Syntax

MATCHES(<string>,<string with regular expression>)

Description

Returns a boolean value (true or false) depending on whether a string matches a regular expression. Datameer tries to match entire record without automatically adding or $ to the regular expression. But if the record has multiple lines, then this must be accounted for with (?s) or line terminatorsThe each cell must have a value and can't contain a <null> value. Update columns containing <null> values using functions like DENULLIFY or ISNULL.
