Loop Through Key Value Pairs Of A Jsonb Object In Postgresql Function

Postgresql Jsonb Insert Function Use jsonb each(jsonb) or jsonb each text(jsonb) in a for loop like: returns jsonb. language plpgsql as language declaration required . declare . key text; value text; begin for key, value in select * from jsonb each text($1) loop. do some math operation on its corresponding value . raise notice '%: %', key, value; end loop;. This plpgsql script selects the keys from a set of jsonb object key:value pairs, but how to select the value for each pair? do $body$ declare js jsonb := ' {"a": "1", "b": "2", "c": "3"}';.

Issue With Inserting Json With Multiple Key Value Pairs In Postgresql Sql json functions json exists(), json query(), and json value() described in table 9.52 can be used to query json documents. each of these functions apply a path expression (an sql json path query) to a context item (the document). The jsonb each function expands the outermost jsonb object into a set of key value pairs. it allows you to decompose a jsonb object into individual rows, each representing each row represents one key value pair. Loop through key value pairs of a jsonb object in postgresql function roel van de paar 185k subscribers 1. The jsonb object stores a massive amount of textual data in the form of key value pairs same as the json objects do. we can get all the keys from the given jsonb object using the jsonb object keys () function in postgres.

I am trying to create a function in postgres that can loop through each key value pair in a given jsonb object. The postgresql jsonb each text () function expands a specified top level member of a jsonb object into a collection of key value pairs (both keys and values are of type text). Where exists (select * from jsonb array elements(d.rawjson) as r(jdoc) where (jdoc >> 'a')::int < 2 and (jdoc >> 'b')::int < 8); if your columns is not a jsonb (which it should be), use json each() instead. online example. I want to loop through each key value pair in the object. as you can tell from my comment, i used to write backend code with more general purpose programming languages like c, java, etc.
