The where clause which I have:
r.completed <= '2017-01-12'
The r.completed (datetime) values are formatted as for example:
2017-01-06 14:48:29
This where clause doesn't select instances that are equal to the date given. How could I fix this problem? I have tried convert(datetime, '2017-01-12') but this gives an SQL error. DBMS is MySQL.
The date 2017-01-12
is translated to 2017-01-12 00:00:00
So a value like 2017-01-12 14:48:29
is greater than 2017-01-12 00:00:00
.
If you want to match also this particular day you would have to use r.completed < '2017-01-13'
在MySQL中,您可以使用
CAST(r.completed as DATE) <='2017-01-12'
Try this if you want to inlcude all time of the given date
r.completed < '2017-01-13'
The above will include all date before start of 2017-01-13
