Hi All,
I have a table that looks like this:

Date | Event
01/01/2008 | CRG
01/01/2008 | MAG
01/01/2008 | CPY
01/02/2008 | CPY
01/02/2008 | MAG
01/02/2008 | MAG
01/03/2008 | CRG
01/03/2008 | CPY

I need to display the data like this:

Date | CRG | MAG | CPY | Total
01/01/2008 | 1 | 1 | 1 | 3
01/02/2008 | 0 | 2 | 2 | 4
01/03/2008 | 1 | 0 | 1 | 2

Thank you so much for your help.

[code]SELECT Date,
COUNT(CASE WHEN Event='CRG' THEN Event ELSE NULL END) AS CRG,
COUNT(CASE WHEN Event='MAG' THEN Event ELSE NULL END) AS MAG,
COUNT(CASE WHEN Event='CPY' THEN Event ELSE NULL END) AS CPY,
COUNT(Event) AS Total
FROM YourTable
GROUP BY Date[/code]

visakh answer is correct with a slight modification in the display of date

SELECT CONVERT(VARCHAR(50),Date,1O1) AS DATE,
COUNT(CASE WHEN Event='CRG' THEN Event ELSE NULL END) AS CRG,
COUNT(CASE WHEN Event='MAG' THEN Event ELSE NULL END) AS MAG,
COUNT(CASE WHEN Event='CPY' THEN Event ELSE NULL END) AS CPY,
COUNT(Event) AS Total
FROM YourTable
GROUP BY Date
