jsonb - Postgresql json like query

Question

I have the following table called module_data. Currently it has three rows of entries:

                id                               data
0ab5203b-9157-4934-8aba-1512afb0abd0 {"title":"Board of Supervisors Meeting","id":"1i3Ytw1mw98"}
7ee33a18-63da-4432-8967-bde5a44347a0 {"title":"Board of Supervisors Meeting","id":"4-dNAg2mn6o"}
8d71ca35-74eb-4751-b635-114bf04843f1 {"title":"COPD 101", "id":"l9O0jCR-sxg"}

Column data's datatype is jsonb. I'm trying to query it using like operator. Something like the following:

SELECT * FROM module_data WHERE title LIKE '%Board%';

I've been looking at the jsonb support and there doesn't seem to be a like operator. If anyone has any advice.

Answer 1

If the data column is text type, then use ->> on cast:

select * from module_data where data::json->>'title' like '%Board%'

If it's already json:

select * from module_data where data->>'title' like '%Board%'
