Hello,
How do you get the row count of the resultset returned from a select statement? I want both the resultset and the count.

Maybe if you told us why you need the row count before you read the rows, we could offer best practice suggestions based on our experience.

Conglomerate:

SELECT IDENTITY([int],1,1) AS [Idx], [stuff], [morestuff] INTO #tblTemp
FROM [tblOriginalSelectStuff]

Have both count (normally I'd SELECT COUNT(*) FROM etc) and that count's in a column of it's own. As a good index also.

Depends on how you are reading the results. If you are using the SqlDataReader, then you have to iterate through each row and count them manually as you process them from the reader - SqlDataReader has no row count, as it doesn't read all the records at once so it doesn't know how manythere are until it's read the last one.

If you use a DataAdapter and a DataSet or DataTable, then your can fill it and use the DataTable.Rows.Count property at any time.
