REGEXP_CONTAINS not recognized

Happy new years, stackoverflow!

I am trying to use some regex functions in bigquery but some of them return error as if I have the name wrong.

SELECT REGEXP_CONTAINS(path, r'^abc$') FROM [tablename]

Query Failed
Error: 2.24 - 2.26: Unrecognized function regexp_contains

Where as if I do a similar regex function, the function text in the editor changes color and the query works.

SELECT REGEXP_EXTRACT(path, r'^abc$') FROM [tablename]

It should work since it's documented in this link.

Does anyone know how to fix this?

BigQuery Legacy SQL and Standard SQL support different set of regular expression functions Legacy SQL Regular Expression Functions:
REGEXP_MATCH, REGEXP_EXTRACT and REGEXP_REPLACE

Standard SQL Regular Expression Functions:
REGEXP_CONTAINS, REGEXP_EXTRACT, REGEXP_EXTRACT_ALL and REGEXP_REPLACE

So, in your case just make sure you use proper BigQuery SQL dialect 

#standardSQL
SELECT REGEXP_CONTAINS(path, r'^abc$') FROM [tablename]
