Enforce check constraint on JSON type

Details

    • Task
    • Status: Closed (View Workflow)
    • Major
    • Resolution: Fixed
    • 10.4.3
    • JSON
    • None

    Description

      Since there's no context where someone will want a JSON type without the constraint, and excluding it causes compatibility problems with MySQL, why not map

      CREATE TABLE t (j JSON);

      to

      CREATE TABLE t (
      		 
        j JSON 
        CHECK (JSON_VALID(j))
      		 
      );
