    <p>I have a query which counts pickups, and divides it by client ethnicity and category. It works, but I need calculate one column <code>'Pickups as % of Active'</code> which is total count of active clients in client table (Active client is StatusID in (1,2,6) in Clients table, all other statuses count as nonactive) My query looks like </p> <pre><code>SELECT max(a.AgencyName)as Agency, COUNT(PickupID)as Pickups, ( COUNT(PickupID)/(select COUNT( c.ClientID) AS ActiveClients FROM Clients c WHERE c.StatusID in (1,2,6) GROUP BY c.AgencyID)) as 'Pickups as % of Active', --SUM(CASE WHEN c.StatusID in (1,2,6) THEN 1 ELSE 0 END)/ COUNT(PickupID) as 'Pickups as % of Active', count (CASE WHEN p.CategCode = 'NB' THEN p.CategCode END) as NB ,count (CASE WHEN p.CategCode = 'IN' THEN p.CategCode END) as 'IN' ,count (CASE WHEN p.CategCode = 'CH' THEN p.CategCode END) as 'CH' ,count (CASE WHEN p.CategCode = 'PG' THEN p.CategCode END) as 'PG' ,count (CASE WHEN p.CategCode = 'BF' THEN p.CategCode END) as 'BF' ,count (CASE WHEN p.CategCode = 'PP' THEN p.CategCode END) as 'PP' ,count (CASE WHEN p.CategCode = 'SR' THEN p.CategCode END) as 'SR' ,count (CASE WHEN p.EthnCode = 'N' THEN p.EthnCode END) as Nat ,count (CASE WHEN p.EthnCode = 'A' THEN p.EthnCode END) as Asn ,count (CASE WHEN p.EthnCode = 'B' THEN p.EthnCode END) as Blk ,count (CASE WHEN p.EthnCode = 'P' THEN p.EthnCode END) as Pac ,count (CASE WHEN p.EthnCode = 'W' THEN p.EthnCode END) as Wth ,count (CASE WHEN p.EthnCode NOT IN ('N', 'A', 'B', 'P', 'W', '0') THEN p.EthnCode END) as Nat ,count (CASE WHEN p.EthnCode = '0' THEN p.EthnCode END) as Unknown ,count (CASE when PickupHispanic=1 then PickupHispanic end) as Hispanic FROM dbo.Pickup p join Agency a on p.agencyid = a.agencyid join Clients c ON c.ClientID = p.ClientID where PickupDate between '2013-01-01' and '2013-01-31' group by a.AgencyID WITH ROLLUP order by 1 </code></pre> <p>end it throws error </p> <pre><code>Msg 512, Level 16, State 1, Line 5 Subquery returned more than 1 value. This is not permitted when the subquery follows =, !=, &lt;, &lt;= , &gt;, &gt;= or when the subquery is used as an expression.

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.
