      Description

      We shouldn't be running EXPLAIN on non-Data Manipulation Statements, of which the most common are:

      SELECT
      UPDATE
      INSERT
      DELETE
      

      Otherwise we see the following error in QAN2:

      Examples of where EXPLAIN has thrown ERROR 1064 are:

      LOCK TABLES
      SET
      QUIT
      SHOW SLAVE STATUS

      Maybe in this case it should return message: EXPLAIN failed: cannot convert query to SELECT or other relevant message.

       

       

      Task 

      Implement User-friendly Error warning - "This type of query is not supported for EXPLAIN."
