join problem

har denna sql-sats men den funkar ej.
tar jag bort de rader som är feta så funkar det, why?

Sqlta = "SELECT Ta.Id AS Taid, Ta.Description AS tadescription, "&_
"Ta.Userid AS Tauserid, Sp.Startdate AS Spstartdate, "&_
"Sp.Stopdate AS Spstopdate, Ar.Id AS Arid, "&_
"Ar.Areaname AS Arareaname, Ar.Areanumber AS Arareanumber, "&_
"Us.Username AS Ususername[b], Ina.Week AS Inweek [/b]"&_
"FROM Tasktbl Ta INNER JOIN Usertbl Us ON Ta.Userid = Us.Id "&_
"INNER JOIN Areatbl Ar ON Ta.Areaid = Ar.Id "&_
"INNER JOIN Specifieddaytbl Sp ON Ta.Id = Sp.Taskid "&_
[b]"INNER JOIN Intervaltbl Ina ON Ta.Id = Ina.Taskid "&_[/b]
"WHERE Sp.Startdate >= '" & Startdate & "' AND Sp.Startdate <= '" & Stopdate & "' OR "&_
"Sp.Stopdate >= '" & Startdate & "' AND Sp.Stopdate <= '" & Stopdate & "'[b] OR "&_
"Ina.Week = '" & Weekstart & "'[/b] ;"

jag får heller inga felmeddelanden, den visar bara inte några poster.

Det kan man inte säga något om då det beror på vilket data du har i dina tabeller. I alla fall så borde du lägga till några parenteser i where.

Sqlta = "SELECT Ta.Id AS Taid, Ta.Description AS tadescription, "&_
"Ta.Userid AS Tauserid, Sp.Startdate AS Spstartdate, "&_
"Sp.Stopdate AS Spstopdate, Ar.Id AS Arid, "&_
"Ar.Areaname AS Arareaname, Ar.Areanumber AS Arareanumber, "&_
"Us.Username AS Ususername, Ina.Week AS Inweek "&_
"FROM Tasktbl Ta INNER JOIN Usertbl Us ON Ta.Userid = Us.Id "&_
"INNER JOIN Areatbl Ar ON Ta.Areaid = Ar.Id "&_
"INNER JOIN Specifieddaytbl Sp ON Ta.Id = Sp.Taskid "&_
"INNER JOIN Intervaltbl Ina ON Ta.Id = Ina.Taskid "&_
"WHERE (Sp.Startdate >= '" & Startdate & "' AND Sp.Startdate <= '" & Stopdate & "') OR ("&_
"Sp.Stopdate >= '" & Startdate & "' AND Sp.Stopdate <= '" & Stopdate & "') OR "&_
"Ina.Week = '" & Weekstart & "' "

Du får försöka dela upp det i mindre delar. Är det where delen som gör att du inte får någon träff eller är det join?

det måste vara joinen som ställer till det, jag provade att ta bort Ina.Week = '" & Weekstart & "' men den visar inget ändå.
Konstigt, de funkar ju var för sig:

Sqlta = "SELECT Blah... "&_
"FROM Tasktbl Ta INNER JOIN Usertbl Us ON Ta.Userid = Us.Id "&_
"INNER JOIN Areatbl Ar ON Ta.Areaid = Ar.Id "&_
"INNER JOIN Specifieddaytbl Sp ON Ta.Id = Sp.Taskid "&_
"WHERE Sp.Startdate >= '" & Startdate & "' AND Sp.Startdate <= '" & Stopdate & "' OR "&_
"Sp.Stopdate >= '" & Startdate & "' AND Sp.Stopdate <= '" & Stopdate & "' ;"

och...

Sqlta = "SELECT Blah..."&_
"FROM Tasktbl Ta INNER JOIN Usertbl Us ON Ta.Userid = Us.Id "&_
"INNER JOIN Areatbl Ar ON Ta.Areaid = Ar.Id "&_
"INNER JOIN Intervaltbl Ina ON Ta.Id = Ina.Taskid "&_
"WHERE Ina.Week = '" & Weekstart & "' ;"

då får jag resultat på båda.
