JSONB列查询

Question

There is a JSONB column ( some_strings ) that has value like string array

---------------------
["string1","string2","string3"]
["string5"]
["string6","string7"]

-------etc-----------

Is there a way to make a query to get row where (some_strings) contain "string2" ?

Answer 1

This query will return records where string2 appears anywhere in the JSONB array:

SELECT *
FROM yourTable
WHERE some_strings ?& array['string2']
