Question

I’m sure this is a VERY simple problem, but I’ve not been able to figure it out. Here’s my query:

select column1 from table1 with(nolock)
where column1 like '2011-07-0[78]%'
order by column1 desc

As you can tell, I’m querying a row looking for timestamps that are from either today or yesterday.

A full timestamp within one of these rows looks like this:

2011-07-08 12:16:39.553

I’ve done similar things many times with no trouble, but the above query returns no results no matter what I try. (Yes, there are timestamps from today and yesterday in the column).

Have I made a syntax error? Am I crazy? Are there gnomes in my DB messing with my query? Please help! Thank you so much!

Answer 1

If the datatype for that field is datetime or smalldatetime then LIKE won’t work as expected.

You could do a DATEPART function or BETWEEN, like:

WHERE DATEPART(Year, column1) = 2011
AND DATEPART(Month, column1) = 7
AND DATEPART(Day, column1) IN (7, 8)

or

WHERE column1 BETWEEN '2011-07-07' AND '2011-07-08'

Bear in mind BETWEEN is inclusive.
