Getting a Subset of Records along with Total Record Count

Question

I\'m working on returning a recordset from SQL Server 2008 to do some pagination. I\'m only returning 15 records at a time, but I need to have the total number of matches along

Answer 1

I've handled a situation a bit similar to this in the past by not bothering to determine a definite row count, but using the query plan to give me an estimated row count, a bit like the first item in this link describes:

The intention was then to deliver whatever rows have been asked for within the range (from say 900-915) and then returning the estimated row count, like

rows 900-915 of approx. 990

which avoided having to count all rows. Once the user moves beyond that point, I just showed

rows 1000-1015 of approx. 1015

i.e. just taking the last requested row as my new estimate.
