Re: JSON query help

I think I'm pretty close:

SELECT
cost_details->'Accounting'->jsonb_object_keys(cost_details->'Accounting')->'BalanceUUID'
AS BalanceUUID,
cost_details->'Accounting'->jsonb_object_keys(cost_details->'Accounting')->'Units'
AS Cost
FROM cdrs
WHERE cost > 0
AND cost_details->'AccountSummary'->'BalanceSummaries' @>
'[{"ID":"B_MONETARY_POSTPAID"}]'
AND cost_details->'AccountSummary'->'BalanceSummaries' @>
jsonb_build_object('UUID'::text,
cost_details->'Accounting'->jsonb_object_keys(cost_details->'Accounting')->'BalanceUUID')::jsonb
LIMIT 1;

ERROR:  function jsonb_build_object(text, jsonb) does not exist
