postgresqlHow can I use jsonb_set to update a PostgreSQL database?

JSONB_SET is a PostgreSQL function used to update fields in a JSONB column. It allows for the insertion of new values, as well as the replacement of existing values.

Example

UPDATE my_table
SET my_jsonb_column = jsonb_set(my_jsonb_column, '{name}', '"John"')
WHERE id = 1;

The above example will update the my_jsonb_column in my_table with the id of 1 and set the name field in the JSONB column to John.

Code explanation

1. UPDATE my_table - This is used to indicate which table we are updating.
2. SET my_jsonb_column = jsonb_set(my_jsonb_column, '{name}', '"John"') - This is used to set the my_jsonb_column to the return value of jsonb_set with the name field and the value John.
3. WHERE id = 1 - This is used to indicate which record we are updating.
