    Description

      SET @aaa = COLUMN_CREATE('price', 0xF0F1F2F3F4F5F6F7);
      		 
      SELECT COLUMN_GET(@aaa, 'price' AS DECIMAL) aaa;
      		 
      SHOW WARNINGS;

      returns this warning:

      +---------+------+---------------------------------------------------------+
      		 
      | Level   | Code | Message                                                 |
      		 
      +---------+------+---------------------------------------------------------+
      		 
      | Warning | 1918 | Encountered illegal value '' when converting to DECIMAL |
      		 
      +---------+------+---------------------------------------------------------+

      Notice, the empty string in the warning text, instead of the actual data.

      The expected result it to escape unreadable data, like it's done everything else, e.g:

      SELECT _binary 0xF1F2F3F4F5F6F7 + 0;
      		 
      SHOW WARNINGS;
