       CAST(LEAST('0000-00-00',DATE'2001-01-01') AS CHAR) AS string,
      		 
       CAST(LEAST('0000-00-00',DATE'2001-01-01') AS DATE) AS date,
      		 
       CAST(LEAST('0000-00-00',DATE'2001-01-01') AS DATETIME) AS datetime,
      		 
       CAST(LEAST('0000-00-00',DATE'2001-01-01') AS TIME) AS time,
      		 
       CAST(LEAST('0000-00-00',DATE'2001-01-01') AS DECIMAL) AS dc,
      		 
       CAST(LEAST('0000-00-00',DATE'2001-01-01') AS DOUBLE) AS dbl,
      		 
       CAST(LEAST('0000-00-00',DATE'2001-01-01') AS SIGNED) AS sint,
      		 
       CAST(LEAST('0000-00-00',DATE'2001-01-01') AS UNSIGNED) AS uint;


      *************************** 1. row ***************************
      		 
            c0: NULL
      		 
        string: NULL
      		 
          date: NULL
      		 
      datetime: NULL
      		 
          time: 00:00:00
      		 
            dc: 0
      		 
           dbl: 0
      		 
          sint: 0
      		 
          uint: 0

      The expected result is to return NULL for all columns.
