Now you can use these indexes to place the new "TV" element to the right place with jsonb_set().

#POSTGRESQL REPLACE VALUE IN ARRAY SERIES#

If you really want to use jsonb_set (which make no sense here, I believe) you could do something like: SELECT I have built a series of views in a PostgreSQL database that includes a couple of array columns. I have 2 text columns where I need to replace (on update) chars from array 1 ('q','x','y','z') to their index-equivalent value in array 2 ('a','b','c','d'). Jsonb_array_elements_text(mydata) as elem An example from documentation: CREATE FUNCTION sum (int ) RETURNS int8 AS DECLARE s int8 : 0 x int BEGIN FOREACH x IN ARRAY 1 LOOP s : s + x END LOOP RETURN s END LANGUAGE plpgsql For you, mu's answer is better, but most users who find this. Jsonb_agg(CASE WHEN elem = 'Tv' THEN 'TV' ELSE elem END) as new_array Solution to replace NULLs in an integer array in PostgreSQL: Postgres 9.3 or later has arrayreplace (anyarray, NULL, anyelement) for any array. Since PostgreSQL 9.1 you can use FOREACH LOOP to iterate over an array. In any other ways ( if you want to keep the order!) you need to expand the array elements into separate rows (either for retrieving the index of the old "Tv" to set the new "TV" to the same position using jsonb_set or for string search/replace) and reaggregate all.

#POSTGRESQL REPLACE VALUE IN ARRAY UPDATE#

Let me know other alternatives and best practices as I have 5M records to do update that and I want to use something like jsonb_set on myĬase also. I want to know other alternatives to update that element on jsonb column. Combine both and you get this: alvherre select unnest (stringtoarray ('the quick lazy fox', ' ')) unnest - the quick lazy fox (4 filas) Since 8.2 does not have. Except where noted, these functions and operators are declared to accept and return type text. You can split an array to a resultset by using the unnest function, and you can turn a string literal into an array by using the stringtoarray function. update asset set eventsconnected jsonbset ( eventsconnected, array elemindex::text, 'events', nested. The sub query that finds the matching params seem to work.

#POSTGRESQL REPLACE VALUE IN ARRAY CODE#

Strings in this context include values of the types character, character varying, and text. EDIT: I've played around with this code which almost works, but it updates all rows with the new object instead of simply inserting/updating the event id and keys that matches. SET amenity_categories = replace(amenity_categories::TEXT,'"Tv"','"TV"')::jsonb This section describes functions and operators for examining and manipulating string values. What is working: UPDATE test_jsonb_update Postgres provides the following string replacement function: with fruits as (select unnest (fruits) AS fruitname from arrayexample ) select replace (fruitname,’ap’,’AP’) from fruits Fruitname. I am using postgresql 12.4 with 5M rows on that table.

#POSTGRESQL REPLACE VALUE IN ARRAY TV#

Sub."elem_index" IS NOT NULL AND sub.I want to update a jsonb column to replace an element of array inside it e.g Tv to TV. Jsonb_array_elements(elem->'events') with ordinality arr2(elem2, pos2) When working in older versions, a common trick is to place a regexpmatches() call in a sub-select, for example: SELECT col1, (SELECT regexpmatches(col2, '(bar)(beque)')) FROM tab This produces a text array if there's a match, or NULL if not, the same as regexpmatch() would. Jsonb_array_elements(events_connected) with ordinality arr(elem, pos), However, regexpmatch() only exists in PostgreSQL version 10 and up. SELECT jsonstripnulls ( jsonbuildobject ( 'Name', shortname, 'IDS', CASE SIGN (position ('ACCEPTED' IN status) ) WHEN 1 THEN jsonbbuild. Edit: But as you require non-null values to show as an array, move the jsonbbuildarray () function into the case statement. I've tried this command UPDATE asset SET detail = jsonb_set(detail, ''::jsonb, Note that jsonstripnulls () doesn't remove null values from JSON arrays. I have some nested JSONB object/arrays that I want to update/insert into array completely when a given set of values match.
