> ah, regexp_like() is good. Thanks [@Omega359](https://github.com/Omega359) But it makes me confused why some functions works in both select and where (regexp_like) and some not (regexp_match, probably others). and not something that I have seen in documentation. regexp_like returns booleans, the others do not. Where requires it's clauses to evaluate to boolean. ```sql select * from t where regexp_match(a, 'a') is not null; ``` may also work ... untested though. -- This is an automated message from the Apache Git Service.
