SQL pivot question

Hi SQL server experts,

I've got this some what older SQL server running (version 9.00.5057.00) and I try to make Pivot query work.

I've got this query that is successful on a access database. But now I'd like to make it work in MS SQL.

TRANSFORM Min("X") AS Expr1 SELECT membership.groep FROM membership GROUP BY membership.groep PIVOT membership.username;

Open in new window



But it does not work on my old sql server.
Is this because my server it to old and my SQL server does not support pivoting?

Or is something wrong with my syntax?

The result should show a table with horizontal usernames, vertical groupnames end where they match an X marks the spot.
Below the desired result:
results
Kind regards,

There is no TRANSFORM command in Technet article about using PIVOT. I think that command is only in MS Access SQL dialect.
Unfortunately, I don't have an access to my MS SQL Server just now, so I cannot tell you the proper form of SQL command you need, but read about converting PIVOT query from Access to SQL Server.

You can't use the same MS Access's syntax in MS SQL Server.
PIVOT exists in SQL Server but only works together with an aggregate function and you need to explicitly tell to the engine which values are part of the PIVOT.
In your example I think the SQL Server code should be something like:
SELECT *
FROM (
           SELECT groep 
           FROM membership
) t
PIVOT 
(MIN(ColumnNameHere) FOR username IN (Billy, Judy, John)) p

Hi Slubek en Vitor,

Thanks for your responses.

I can't get to work for me.

Maybe I should give you the table layout:

CREATE TABLE membership(
	[memberID] [int] NOT NULL,
	[username] [nvarchar](50) NULL,
	[groupname] [nvarchar](50) NULL
)

insert into membership (memberID,username,groupname) values(28,'Bill','Domain users')
insert into membership (memberID,username,groupname) values(30,'Bill','Application B')
insert into membership (memberID,username,groupname) values(33,'Judy','Domain users')
insert into membership (memberID,username,groupname) values(34,'Judy','Application A')
insert into membership (memberID,username,groupname) values(36,'John','Domain users')
insert into membership (memberID,username,groupname) values(37,'John','Application B')
insert into membership (memberID,username,groupname) values(38,'John','Printer 45')

Open in new window


I hope that helps.

Try this one:
SELECT *
FROM (
           SELECT groupname, memberID, username
           FROM membership
) t
PIVOT 
(MIN(memberID) FOR username IN (Bill, Judy, John)) p

It more or less works (see the sqlfiddle below):

http://sqlfiddle.com/#!3/2d0f6/1

But it is limited to called users in the query. And It should show all users (including Abe) without the need to include him in the query.

That's the problem with PIVOT in SQL Server. Isn't dynamic. You really need to specify which records you want to use for PIVOT.
But someone already had the same issue and solve it like this.
