I'll admit that I'm a new MSSQL query writer; however, I'm learning.
I'm curious how I could get a GRAND TOTAL to be included directly under
the [Total] column. Any information would be great!
Thank you!
SELECT Sites.Name [Signups Before 4pm], COUNT(Subscribers.Id) [Total]
FROM Subscribers
JOIN Sites on Sites.Id = Subscribers.SiteId
WHERE Subscribers.DateEntered BETWEEN @.beforestart AND @.beforeend AND
DateOptedOut IS NULL
GROUP BY Sites.Name
ORDER BY Sites.NameTry something like this:
SELECT Sites.Name [Signups Before 4pm], COUNT(Subscribers.Id) [Total]
FROM Subscribers
JOIN Sites on Sites.Id = Subscribers.SiteId
WHERE Subscribers.DateEntered BETWEEN @.beforestart AND @.beforeend AND
DateOptedOut IS NULL
GROUP BY Sites.Name
ORDER BY Sites.Name
COMPUTE SUM(COUNT(Subscribers.Id))|||I really appreciate your help with this. However, I get the following
error:
TDS Protocol error: Unsupported TDS token: 0x88
Thanks again!|||You might also check out the WITH ROLLUP option on GROUP BY

How to improve database searhing performance?
Hi, I am using compact framework 1.1 and SQL CE database for my mobile application. My database has a total of 160000 rows of records and whenever i do a query searching, it will take about 20 seconds to look through the whole database if the record does not exist. Is there any method to improve the searching performance? i am using data reader for the query.
Thanks.
If you are using SQL statements now, consider using Seek/SetRange using an index. More information at http://msdn2.microsoft.com/en-us/library/system.data.sqlserverce.sqlcedatareader.seek.aspx
