Hello,

How would I write in SQL or ASP the following?:
Count number of Database Records between NOW and 24 HOURS EARLIER? I know
how to retrieve recordsets etc - its just the date thing I cant grasp. I am
stuck getting the 24 hours earlier data capture.

Thanks!

Gary.
PS - Sorry for the X-Posting. Just need to answer fairly quickly if at all
possible. Hopefully relevant to all groups!
 
Try this C#:

string yesterday = DateTime.Now.AddDays(-1).ToString();
string now = DateTime.Now.ToString();
string sSQL = "SELECT * FROM FIELD "
+ "WHERE DATE > '" + yesterday + "' AND DATE <= '" + now + "'";

Untested; might be a minor syntax typo but your compiler should catch it.
For instance, I don't remember if dates are 'date' or %date%.

Look, this is a asp and database question. Unless you are using .Net, there
is ONE relevant group for this question: .inetserver.asp.db. Cross-posting
to thousands of semi-related groups will NOT get you a quicker answer.

I would set follow-ups to .inetserver.asp.db if your inclusion of the
dotnet groups hadn't raised the doubt that you might be using .Net.

Why don't you post back to the relevant newsgroup and let us know what
technology you are using (asp or asp.net) AND what type and version of
database you are using (I know you said "SQL", but you could have been
talking about the language, instead of SQL Server.)

When you reply, please set Follow-ups to the relevant newsgroup.

Also note that this code will only work on clients configured for
the American English region.
If the client is configured for another region, than
now and yesterday will be formatted accordingly,
while the SQL string always needs to be in the mm-dd-yy format.

Therefore, it is better to use parameters in the SQL string:

string sSQL = "SELECT * FROM FIELD " +
"WHERE DATE > @date1 AND DATE <= @date2;"
SqlCommand cm = new SqlCommand(sSQL, conn);
cm.Parameters.Add("@date1",yesterday);
cm.Parameters.Add("@date2",now);
