I encountered a problem while using mysql_query_rules

I encountered a problem while using mysql_query_rules:
My rule is to match whether the SQL contains a 'where' query condition, and the corresponding SQL is: INSERT INTO mysql_query_rules ( rule_id, active, username, match_pattern, error_msg, apply, flagOUT )
VALUES
( 103, 1, 'root', '^UPDATE\s+[^\s]+\s+SET\s+(?!\sWHERE\s+).$', 'The Update statement must contain a valid WHERE condition.', 1, 14 );
Executing SQL: update sys_user SET user_name='test 'can match, but in reality, the executed SQL has line breaks. How should we handle line breaks? For example:
update sys_user
SET
user_name='test'
