I have a column with json type but I'm wondering how to select filter it i.e.
select * from fooTable where myjson like "orld";
How would I query for a substring match like the above. Say searching for "orld" under "bar" keys?
{ "foo": "hello", "bar": "world"}
I took a look at this documentation but it is quite confusing.
https://www.postgresql.org/docs/current/static/datatype-json.html
Use the ->> operator to get json attributes as text, example
with my_table(id, my_json) as (
values
(1, '{ "foo": "hello", "bar": "world"}'::json),
(2, '{ "foo": "hello", "bar": "moon"}'::json)
)
select t.*
from my_table t
where my_json->>'bar' like '%orld'
id | my_json
----+-----------------------------------
1 | { "foo": "hello", "bar": "world"}
(1 row)
Note that you need a placeholder % in the pattern.
