SQL Count Query in SELECT Statement

Asked by spartasystems in SQL Query Syntax, SQL Server 2005

Tags: MS SQL

Good afternoon all,

I am trying to form a sql select statement that will match a representative to a publication, then count how many adverts they have sold.

I am using 3 tables:

Pub (Holds publication data including Pub_c_PubId)
Advert (Holds details of an advert and stores the Pub_c_PubId as advert_publicationid, it also stores the rep as advert_rep)
ExRep (Holds the Representatives Data such as Rep_Rep, Rep_PublicationId)

Now, If I am looking at a publication I'd like to be able to see which reps are assigned to it:

ThisPublication = Request.QueryString("Pub_c_PubId");

SELECT * FROM ExReps WHERE ExReps.Reps_PublicationID="+ThisPublication;

This is fine and works well, although I'll remove the * and replace with specific fields to reduce query time.

I also would like to see how many adverts each representative has sold:

SELECT COUNT(*) AS NoOfAds FROM Advert WHERE Advert.Advert_PublicationId="+ThisPublication; (I also need to filter by rep here?)

Now I've though about UNION but the tables hold different data so that won't work, I thought about JOIN but cannot seem to structure the query correctly.

It's almost as if I need to run the first query to get the reps, then using that, calculate how many ads they sold.

Would a WHERE EXISTS help with this?

Here is what I have tried: I hope you can see and understand what I'm trying to achieve.Start Free Trial

         
             ThisPublication = Request.QueryString("Pub_c_PubId");
 
query = "SELECT x.Reps_Rep, x.Reps_Assignmentdate, x.Reps_Assignmentstatus, COUNT(advert_advertid) AS NoOfAds FROM Advert a, ExReps x WHERE a.advert_publicationid="+ThisPublication+" AND a.advert_rep=e.reps_rep AND Reps_Rep IN (SELECT * FROM ExReps e WHERE e.reps_publicationid="+ThisPublication+");
 
//This errors saying: ExReps.Reps_Rep is invalid in the select list because it is not contained in either an aggregate
//function or the Group By clause
