Oracle_error.sql

CREATE TABLE JSON_TEST(
	ID NUMBER(19, 0) NOT NULL,
	JSON_COLUMN VARCHAR2(4000 CHAR) NOT NULL
);

ALTER TABLE JSON_TEST ADD CONSTRAINT CHECK_JSON CHECK (JSON_COLUMN IS JSON);

INSERT INTO JSON_TEST (ID, JSON_COLUMN) VALUES (1, '{"languages": [{"id": "1", "name": "java"}, 
					   											   {"id": "2", "name": "clojure"},
																   {"id": "3", "name": "sql"}]}');
WITH json as

    select * 
    from JSON_TEST j,  
		 json_table(j.JSON_COLUMN, '$' columns (
