      Description

      SHOW VIEW statement is actually not supported in Spark SQL. However, when a user quries such a statement, the error message is confusing. For example, the error message for

      SHOW VIEWS IN my_database
      

      is

      missing 'FUNCTIONS' at 'IN'(line 1, pos 11)
      

      which is misleading.
       

      One possible way to fix is to explicitly capture these statements in a grammar rule and print user-friendly error message such as

      SHOW VIEW statements are not supported.
