Hello,
I've been trying for a couple of days now with the following problem in SQL
Ive a table called tblRresults that has the following
Date - just a regular date
OfficeLocation - just a unique id such as a zip code
SampleType - contains things like wall, floor, beam
SampleResult - "Detected" or "NotDetected"
When populated the table can look like
12/12/05 99505 Wall Detected
12/12/05 99505 Wall NotDetected
10/04/05 99211 Beam Detected
10/04/05 99211 Beam Detected
10/04/05 99111 Floor NotDetected
10/04/05 99111 Floor NotDetected
What I want is (I guess) a crosstab query that produces the following
Date Location SampleType CountDetected CountNotDetected
12/12/05 99505 Wall 1 1
10/04/05 99211 Beam 2 0 (or null would be ok)
10/04/05 99111 Floor 0 2
Any help gratefully accepted, this has been driving me mental!
thanks
Select Date,Location,SampleType,SUM(CASE WHEN SampleResult='Detected' THEN 1 ELSE 0 END) AS CountDetected,SUM(CASE WHEN SampleResult='NotDetected' THEN 1 ELSE 0 END) AS CountNotDetected
FROM table
GROUP BY Date,Location,SampleType
|||thanks very much! - I had no idea CASE existed
