>= GETDATE() not returning rows with today's date

Question

---------------------
| ID  |     date    |
|-----+-------------|
|  1  |  2013-12-30 |
|  2  |  2014-01-03 |
|  3  |  2014-02-02 |
---------------------

column ID is int type

column date is Date type

When i use SELECT CAST (getdate() as date) currentDay, ID FROM table WHERE date >= GETDATE(), it only returns:

--------------------------------------
|  currentDay   |  ID  |     date    |
|---------------+------+-------------|
| 2013-12-30    |   2  |  2014-01-03 |
| 2013-12-30    |   3  |  2014-02-02 |
--------------------------------------

it does not return the row with ID=1.

In other words, >=GETDATE() does not return rows with today's date.

What did I do wrongly?

Answer 1

It doesn't return any rows with today's date because GETDATE() gives date and time. So, in your example, converting 2013-12-30 to a DATETIME gives you 2013-12-30 00:00:00, which isn't equal or greater than 2013-12-30 12:09:35 (the result of GETDATE() for me in this moment). You need to use:

WHERE date >= CONVERT(DATE,GETDATE())

Answer 2

The GETDATE() function returns the current date and time (i.e. including the time part). So it is normal that today's date (without the time part) is smaller than GETDATE() ( unless you run your query at midnight precisely ). This is why you don't get the expected result.
