SQL Server Pivot Query

I have an email table with 3 columns

the typeresponse has 5 possible types (open, bounce, deferred, click, unsubscribe)

I need a select that groups by CampaignID and emailaddress
And then place a 1 or 0 in the 5 pivoted columns if that record exists

As in
CampaignID   emailaddress    open     bounce     deferred     click    unsubscribe
12345              test@live.com     1               0                 0                1              0

You can use the PIVOT operator:

DECLARE @campaignTable TABLE (CampaignID INT            NOT NULL,
                              EmailAddress VARCHAR(255) NOT NULL,
                              TypeResponse VARCHAR(25)  NOT NULL

INSERT INTO @campaignTable (CampaignID, EmailAddress, TypeResponse)
VALUES (123, 'openresponse@123.com',         'Open'),
       (123, 'bouncedresponse@123.com',      'Open'),
       (123, 'bouncedresponse@123.com',      'Bounce'),
       (123, 'clickresponse@123.com',        'Open'),
       (123, 'clickresponse@123.com',        'Click'),
       (234, 'donotdisturbresponse@123.com', 'Open'),
       (234, 'donotdisturbresponse@123.com', 'Unsubcribe'),
       (345, 'bouncedresponse@123.com',      'Open'),
       (345, 'bouncedresponse@123.com',      'Bounce'),
       (345, 'deferredresponse@123.com',     'Deferred'),
       (345, 'clickresponse@123.com',        'Open'),
       (345, 'clickresponse@123.com',        'Click');

SELECT PivotedTable.CampaignID,
FROM (SELECT ct.CampaignID,
      FROM @campaignTable AS ct
     ) AS SourceTable
PIVOT (COUNT(SourceTable.TypeResponse) FOR TypeResponse IN ([Open], 
      ) AS PivotedTable
ORDER BY PivotedTable.CampaignID,

Open in new window

Perfect... as always thanks.
Quick follow-up
This may be run on 50k records at a time.
Should that be a concern if the indexes are "optimized?"
Guy Hengel [angelIII / a3]Billing EngineerCommented:
50k records is not big.
and unless a clustered index on either campaignid or email a index is not needed or helpful
