    Description

      This script correctly rejects an invalid value being inserted into a JSON column:

      CREATE OR REPLACE TABLE t1 (a JSON);
      INSERT INTO t1 VALUES ('Foobar');
      ERROR 4025 (23000): CONSTRAINT `t1.a` failed for `test`.`t1`
      

      Assigning the same invalid value to a JSON SP variable works without errors:

      DELIMITER $$
      CREATE OR REPLACE PROCEDURE p1()
      BEGIN
        DECLARE v1 JSON;
        SET v1 = 'Foobar';
        SELECT v1;
      END;
      $$
      DELIMITER ;
      CALL p1();
      

      +--------+
      | v1     |
      +--------+
      | Foobar |
      +--------+
      

      The assignment should probably fail as well.
