    <p>Add your test to an expression that returns 1 if successful and 0 otherwise. Then add it up and divide it by your total to get the percentage.</p> <p>You can use something like the following:</p> <pre><code>SUM(CASE WHEN c.StatusID in (1,2,6) and p.PickupDate between '2012-01-01' and '2012-01-31' THEN 1 ELSE 0 END) / COUNT(PickupID) as 'Pickups as % of Active' </code></pre> <p>EDIT: OK, I see that I was wrong the first time. You could get a count of active as a subquery instead:</p> <pre><code>SELECT max(a.AgencyName)as Agency, COUNT(PickupID)as Pickups, COUNT(PickupID) / ActiveClients 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 (select c.ClientID, COUNT( c.ClientID) AS ActiveClients FROM dbo.Pickup p JOIN Clients c on c.ClientID = p.ClientID WHERE c.StatusID in (1,2,6) and p.PickupDate between '2012-01-01' and '2012-01-31' GROUP BY c.ClientID ) ActiveClientCounts ON p.ClientID = ActiveClientCounts.ClientID where PickupDate between '2012-01-01' and '2012-01-31' group by a.AgencyID WITH ROLLUP order by 1 </code></pre>

    2. COChanged my approach. Basically, you already have the pickups. You just need to divide that by the active clients, which you can get with a subquery. I might have typed it wrong - just make yourself a query that gets what you want and add the SQL at the bottom.

Querying!

 
Guidance
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.

SQuiL has stopped working due to an internal error.

If you are curious you may find further information in the browser console, which is accessible through the devtools (F12).
