json - How can I perform a LIKE query for a jsonb key? -


i have following jsonb structure:

{'this': '1', 'this_that': '0', 'this_and_that': '5'}

how select rows contain operator?

select * myjson j ? 'this_%'

returns 0 rows...was hoping match 'this_that' , 'this_and_that'. (note: characters following '_' potentially vary , therefore not able exact match).

your example should not work because there not implicit cast between jsonb , text types. can enforce casting:

select '{"this": 1, "this_that": 0, "this_and_that": 5}'::jsonb::text              '%"this%';

it not clean solution. better unpacking json, , filtering on unpacked data lateral join

postgres=# select key  myjson, lateral jsonb_each_text(j)               key 'this\_%'; ┌───────────────┐ │      key      │ ╞═══════════════╡ │ this_that     │ │ this_and_that │ └───────────────┘ (2 rows)
