i have stuck :)
does anyone know how query postgresql in jsonb i have table USER
- INT id,
- Varchar name,
- jsonb categoryId
the example data in categoryId field like this = [1,2,3,4,5]
I have tried this query which works:
select *
from user where categoryId @> '2'::jsonb ;
but how to query with multiple params like
select *
from user
where categoryId @> '1,3,4'::jsonb
and i will implement this to hibernate jpa/jpql-predicate, but i want to know native query first
Thankyou so much
In SQL you can use the ?| operator for this
select *
from "user"
where categoryid ?| array['1','3','4'];
That will return rows where at least one of the values is contained in the JSON array. If you want to find those that contain all values, use the ?& operator instead.
To use the @> operator you would need to use a JSON array on the right hand side:
select *
from "user"
where categoryid @> '[1,3,4]'::jsonb
Note that user is a reserved keyword. You will have to enclose it in double quotes every time you want to refer to the table. I would highly recommend to find a different table name.
