Search a JSON array for an object containing a value matching a pattern

Question

I have a DB with a jsonb column where each row essentially holds an array of name value pairs. Example for a single jsonb value:

[
         


        

Answer 1

You can use the function jsonb_array_elements() in a lateral join and use its result value in the WHERE clause:

select distinct t.* 
from my_table t
cross join jsonb_array_elements(jsoncol)
where value->>'value' like '%ba%'

Please, read How to query jsonb arrays with IN operator for notes about distinct and performance.
