SQL Query Problem

Hi there,

I am trying to retrieve the last 100 distinct job positions that have attended an event. Right now the query returns the last 100 job positions but they are not distinct, because I have an order by event start date in my query clause. Is there anyway else I can retrieve this information.
I've posted the query below. I've tried a group by and that didn't work either because of the event start date.

Query:
SELECT DISTINCT TOP 100      WebUser.Wuser_Position, Event.Evnt_Start_Date
FROM             Event INNER JOIN
                  Invoice ON Event.Evnt_ID = Invoice.Evnt_ID INNER JOIN
                  InvoiceItems ON Invoice.Inv_ID = InvoiceItems.Inv_ID INNER JOIN
                  WebUser ON InvoiceItems.Wuser_ID = WebUser.Wuser_ID
WHERE                  (WebUser.Wuser_Position IS NOT NULL) AND (WebUser.Wuser_Enabled = 1) AND
                  (NOT (UPPER(WebUser.Wuser_First_Name) LIKE '%TEST%')) AND
                  (NOT (UPPER(WebUser.Wuser_Last_Name) LIKE '%TEST%'))
ORDER BY             Event.Evnt_Start_Date DESC

Is this SQL Server?

Don't use a single query. Use a stored procedure.

CREATE PROCEDURE get100Positions
AS
CREATE TABLE #tempPos (
position <whatever type Wuser_position is> NOT NULL PRIMARY KEY
)

DECLARE p1 READ-ONLY CURSOR FOR
SELECT
WebUser.Wuser_Position, Event.Evnt_Start_Date
FROM
Event
INNER JOIN
Invoice
ON
Event.Evnt_ID = Invoice.Evnt_ID
INNER JOIN
InvoiceItems ON Invoice.Inv_ID = InvoiceItems.Inv_ID
INNER JOIN
WebUser
ON InvoiceItems.Wuser_ID = WebUser.Wuser_ID
WHERE
(
WebUser.Wuser_Position IS NOT NULL
)
AND
(
WebUser.Wuser_Enabled = 1
)
AND
(
NOT
(
UPPER(WebUser.Wuser_First_Name) LIKE '%TEST%'
)
)
AND
(
NOT
(
UPPER(WebUser.Wuser_Last_Name) LIKE '%TEST%'
)
)
ORDER BY
Event.Evnt_Start_Date DESC

OPEN p1

DECLARE @position <type of Wuser_Position>
DECLARE @startDate DATETIME

FETCH NEXT FROM p1 INTO @postion, @startDate
WHILE @@FETCH_STATUS = 0 AND (SELECT COUNT COUNT(*) FROM #tempPOS) < 100)
BEGIN
IF (SELECT COUNT(*) FROM #tempPOS WHERE position = @position) = 0
BEGIN
INSERT INTO #tempPos (position) VALUES (@position)
END
END

CLOSE p1
DEALLOCATE p1

RETURN
GO

Whoops!

Add before RETURN:

SELECT * FROM #tempPos
