Create table that mirrors the test_data table Copy the data over INSERT INTO test_data_temp (uuid, obj_type, obj_uuid, obj_version_id, data_type, data) SELECT uuid, obj_type, obj_uuid, obj_version_id, data_type, data FROM test_data; Copy the data over INSERT INTO test_data_temp SELECT * FROM test_data; Delete the original test_data table Rename the temporary table to the original table's name Add a column to test_data so that the order of cases may be tracked Make the order_idx column required and initialize all the values to 1 Add unique constraint for design object type, version id, uuid, and order_idx
