See PIVOT[^] in SQL Server. Even a Google on Pivot sql server[^] will help you a lot.

I have done that! Can't work it out tho, as all the example sum values and I dont want to do that. TSQL is not my strong point

[Goutam Patra]

Well Here[^] is an example on Pivot two or more columns. Read through it and try out.

Do I understand that both your sites (A,B,C) and your attributes (X,Y,Z) are variable in number ? And you are counting some sort of occurrence ? My pivot tables show the months across the top, the salesman down the left and the number in the grid represents the number of orders closed in that month. Sound familiar ? Your Pivot might look something like this: select Salesman, [1] as Jan,[2] Feb,[3] Mar,[4] Apr,[5] May,[6] Jun, [7] Jul, [8] Aug, [9] Sep, [10] Oct, [11] Nov, [12] Dec from ( select salesman, OrderID, datepart(month,order_date) as month from orders where datepart(year,order_date) = 2010) AS SourceTable PIVOT (COUNT(OrderID) FOR month in ([1],[2],[3],[4],[5],[6],[7],[8],[9],[10],[11],[12])) AS PivotTable

[int] NOT NULL, [Y] [int] NOT NULL, [Z] [int] NOT NULL ) ON [PRIMARY] insert into Example(Site, X,Y,Z) Values ('A',1,2,3) insert into Example(Site, X,Y,Z) Values ('B',4,5,6) insert into Example(Site, X,Y,Z) Values ('C',7,8,9) select * from Example

This article [^]may be useful, I use MAX (min will do just as well) for the aggregator.

I think the main problem is I need multiple aggregates (for X, Y and Z). I have this so far select * from Example pivot ( Max(X) for site in ([A],[B],[C]) ) as p

[Mycroft Holmes]

Not sure I understand your problem, are you saying you want 3 aggregates(X,Y,Z) for each type(columns) (A,B,C)

I think thats what I need, but not sure. Basically I want to rotate the returned data by 90 degrees

[Jorgen Andersson]

You need to unpivot first, or normalize it actually, into something similar to this format:

CREATE TABLE [dbo].[Example](
[Site] [nvarchar](50) COLLATE Latin1_General_CI_AS NOT NULL,
[Accident] [nvarchar] NOT NULL,
[Occations] [int] NOT NULL,
) ON [PRIMARY]

Either in the query or a temp table, but preferably it should be stored normalized in the database After that you can make the pivot the normal way

In that case work through the article because that is EXACTLY what it does with 2 columns, just extend it to meet your requirements.

Thanks, you were right :) I now have it working.

You should consider normalizing the table. It would make it a lot easier in the future to add functionality. Consider this:

CREATE TABLE Incidents (
Site varchar
IncidentType varchar,
IncidentDate Date,
Incidentinfo varchar,
...
)

Then just make your pivot on Select site,incidenttype,count(*) as incidentcount from incidents You may also exchange site and incidenttype for IDs referencing tables holding info on sites and incidenttypes. If you add a site to your organisation you simply add a row in a table.
