Concatenate them with a space in between.

5.10.3 Discussion

Combining a date value and a time value to produce a date-and-time value is just a matter of concatenating them with a space in between:

mysql> SET @d = '2002-02-28';
mysql> SET @t = '13:10:05';
mysql> SELECT @d, @t, CONCAT(@d,' ',@t);
| @d | @t | CONCAT(@d,' ',@t) |
| 2002-02-28 | 13:10:05 | 2002-02-28 13:10:05 |
