Chris,
Sure, you can join a table multiple times. You're missing a FROM clause and you seem to put column names where table names or aliases ought to be. Is this ...
SELECT tlb1.DepartureLocation AS Departure, tbl1.DepartureLocation AS Destination FROM tbl1 LEFT JOIN tbl2 ON tbl2.DepartureID=tlb1.LocationID LEFT JOIN tbl2 ON tbl2.ArrivalID=tbl1.LocationID ORDER BY tbl2.Time;
what you mean?

Hi,
Is it possible to left join the same data twice?
TBL ONE: LocationID Location, varchar(100)
TBL TWO: DepartureID, ArrivalID, Time
SELECT tlb1.DepartureLocation AS Departure, tbl1.DepartureLocation AS Destination LEFT JOIN DepartureLocation ON tlb2.DepartureID=tlb1.LocationID LEFT JOIN DepartureLocation ON tbl2.ArrivalID=tbl1.LocationID ORDER BY tbl2.Time etc etc etc
I get
ERROR 1066 (42000): Not unique table/alias: 'tbl1'
Thanks.
