#163701

I have always had a problem getting dates.
I mean, I can't get the syntax for dates right.
I need to run a query that can count the number of records based on date criteria.
Here is the one I made that works fine in access, but when I use it in asp code to call to SQL Server, I get "the requested properties cannot be supported"
What is the SQL Server friendly version of this statement?
sql = "SELECT Count(tblLinkRequest.LinkRequestID) AS CountOfLinkRequestID, tblLinkRequest.DateSent FROM tblLinkRequest GROUP BY tblLinkRequest.DateSent HAVING (((tblLinkRequest.DateSent)=#" & Date() & "#));"
Kindest Regards,

sql = "SELECT Count(tblLinkRequest.LinkRequestID) AS CountOfLinkRequestID, tblLinkRequest.DateSent FROM tblLinkRequest GROUP BY tblLinkRequest.DateSent HAVING (((tblLinkRequest.DateSent)='" & Date() & "'));"

It's really that simple? Just take out the #'s?

Unless Date() is some kind of variable you are passing in, you may want to try the following

@sql = 'SELECT Count(tblLinkRequest.LinkRequestID) AS CountOfLinkRequestID, tblLinkRequest.DateSent FROM tblLinkRequest GROUP BY tblLinkRequest.DateSent HAVING (((CONVERT( varchar, tblLinkRequest.DateSent, 101))=' + CHAR(39) + CONVERT( varchar, GETDATE(), 101) + CHAR(39) + '))'

Please note, @SQL is a declared variable. The reason I used the CONVERT( varchar, DateField, 101) is so the timestamp is not part of the equality operation.

Try the following and see the difference: SELECT GETDATE(), CONVERT( varchar, GETDATE(), 101) AS 'Other GETDATE()'

I wasn't born stupid - I had to study.

I found that date formatting is probelmatic with international systems (i.e; French = dd/mm/yyyy).

The best way to pass dates to sql server in any locale is to use a quoted string with the format : 'yyyymmdd'

If you need time information use : 'yyyymmdd hh:nn:ss'

Why are you preparing the SQL string to be executed in your client code anyway? Why don't you use a stored procedure here?

Piggy-backing on Habib, this should be interesting:

The other main difference between dates in Access and SQL Server is that you have to specifically consider the time part in SQL Server. For example checking where Datefield='1/1/05' it won't match to a date stored as '1/1/05 22:05:03'. There are a number of ways to get around this.. you could use a range for example: datefield >= '1/1/05 00:00:00 AND datefield<='1/1/05 23:59:59'

I don't know how to use stored procedures yet.

I am more than willing to try learn though.

SP's are nothing mysterious. First place to look for stored procedures is BOL (aka the online help). Ken Henderson has a book "The Guru's Guide to Stored procedures...." I haven't read it myself, but if it is only half as good as his other two books which I own, it is worth the money.

And as always, when you got stuck with something, search here, or start a thread and someone will help.
