DECLARE CONTINUE HANDLER FOR NOT FOUND SET done = 1; 
  
OPEN cur; 
  
REPEAT 
  
FETCH cur INTO oldname; 
  
SET @newname = UPPER(oldname); 
SET @isNotSame = @newname <> BINARY oldname;  
IF NOT done && @isNotSame THEN  
SET @SQL = CONCAT('rename table `',oldname,'` to `', LOWER(@newname), '_tmp` ');  
PREPARE tmpstmt FROM @SQL;  
EXECUTE tmpstmt; 
 
SET @SQL = CONCAT('rename table `',LOWER(@newname),'_tmp` to `',@newname, '`');
