I have a date column which isn't behaving as expected...
--Determining When Students Enrol and Cancel
Select (ContactEnrollDate)
From PersonalProfiles
Where ContactEnrollDate like '%2006%' ---06-17%' and
(ContactEnrollDate) is not null and ContactCancelDate is not null and LastAttended is not null
This returns 52 results, which is correct. Here are 2 of them.....
2006-03-27 00:00:00.000
2006-12-08 00:00:00.000
However if I just want those students who enrolled in March/December etc, and change the Where clause accordingly:
Where ContactEnrollDate like '2006-03-27%' or Where ContactEnrollDate like '2006-12-08%'
zero rows are returned DESPITE the fact I've seen them in the former result set.
Thanks

If the column is a data-type of datetime, I wouldn't suggest using LIKE expressions. You can use something alone the lines of WHERE YEAR(ContractEnrollDate) = 2006 AND (MONTH(ContractEnrollDate) in (3,12)).
That should give you what you are looking for.

One way to do this is to use a Calendar table, then you can filter for Month/Year.
Otherwise, you'd have to use something like:
WHERE [EventDate] >= '01-Jan-2018' AND [EventDate] <='31-Mar-2018'

Is your date column defined as a datetime or varchar(somevalue)?

Completely agree, and my own research verifies it should, but nonetheless...
"An expression of non-boolean type specified in a context where a condition is expected, near 'ContractEnrollDate'."
The column is of datatype 'Datetime'.

Don't blame my code, I used what you posted.

Let's just fix it:SELECT ContactEnrollDate
FROM PersonalProfiles
WHERE YEAR(ContactEnrollDate) = 2006
AND MONTH(ContactEnrollDate) IN (3,12)
AND ContactCancelDate IS NOT NULL
AND LastAttended IS NOT NULL;
No reason to add a condition for ContactEnrollDate to check for NULL when that will be met merely by having other conditions on it that specify values.

Don't use functions on any column unless you have absolutely no choice. In other words, keep the condition sargable if at all possible
--If you want the months of Mar 2006 and Dec 2006, then this:
WHERE ((ContactEnrollDate >= '20060301' AND ContractEntrollDate < '20060401') OR
(ContactEnrollDate >= '20061201' AND ContractEntrollDate < '20070101'))
--For a specific day in Mar or Dec, then:
WHERE ((ContactEnrollDate >= '20060327' AND ContractEntrollDate < '20060328') OR
(ContactEnrollDate >= '20061208' AND ContractEntrollDate < '20061209'))
