  - You are about to drop the column `event_data_type` on the `event_data` table. All the data in the column will be lost.
  - You are about to drop the column `event_date_value` on the `event_data` table. All the data in the column will be lost.
  - You are about to drop the column `event_id` on the `event_data` table. All the data in the column will be lost.
  - You are about to drop the column `event_numeric_value` on the `event_data` table. All the data in the column will be lost.
