CREATE TABLE tblCompeditors (CompID AutoIncrement,MemberID TEXT(100),FirstName text(100),LastName TEXT(100),Address1 TEXT(100),Address2 TEXT(100),Town TEXT(100),County TEXT(100),PostCode Text(15),Phone Byte,Email TEXT(100),Sex TEXT(10),DOB Date,Club TEXT(100))
CREATE TABLE tblRaceEnterants (CompID LONG,RaceNumber Integer,RaceID TEXT(100),LateEntry TEXT)
CREATE TABLE tblRaceEvents (RaceID TEXT(100),RaceLocation Text,Discription text, DateOn Date)
i have to join all 3 together but havin a problem on the join statment i think i'm missing something
SELECT tblResults.FinishPosition,tblRaceEnterants.RaceNumber,tblResults.FinishTime, tblResults.Age FROM tblResults
INNER JOIN tblRaceEnterants ON tblResults.RaceID = tblRaceEnterants.RaceID INNER JOIN tblCompeditors ON tblResults.CompID = tblCompeditors.CompID
WHERE (tblResults.RaceID = 'FELIXSTOWE-5_KM-25/08/2010');
i can get either with just one join but i need to join both to get the info i need
any help would be great cheers cooney txtPost_CommentEmoticon(':-D');

Well, your query references a "tblResults", which you didn't provide any DDL for. Could it be that you're joining to the wrong table?

You might want to read the first link in my signature, then post some (fake) sample data that shows the problem, and what the expected results should be based on that sample data.

Cheers for the reply just got it kind of working by putting in brackets

SELECT tblResults.FinishPosition,tblRaceEnterants.RaceNumber,tblResults.FinishTime, tblResults.Age FROM ((tblResults

INNER JOIN tblRaceEnterants ON tblResults.RaceID = tblRaceEnterants.RaceID) INNER JOIN tblCompeditors ON tblResults.CompID = tblCompeditors.CompID)

WHERE (tblResults.RaceID = 'FELIXSTOWE-5_KM-25/08/2010');

but i now seem to get an extra column ???????http://www.sqlservercentral.com/Forums/Skins%5CClassic%5CImages/MessageIcons/Whistling.gif
