Hi Mark,

This could be because of the known bug in the View Designer. Even though you are not selecting fields from the 3 different tables you are referencing all 3 because of the joins and the View Designer has problems working with more than 2 tables. HTH

>Can someone explain why I get an error from:
>SELECT Travauth.travid, Travauth.actid, Travauth.empid, ;
>       Travauth.tanum, Travauth.dcn, Travauth.amount, ;
>       Travauth.bgndate, Travauth.enddate, Travauth.destid, ;
>       Accounts.account, Accounts.allotment, Destination.city, ;
>       Destination.state ;
> FROM travel!TravAuth ;
>      LEFT OUTER JOIN travel!Destination ;
>           LEFT OUTER JOIN travel!Accounts ;
>           ON Travauth.actid = Accounts.actid;
>      ON Travauth.destid = Destination.destkey;
> ORDER BY Travauth.empid, Travauth.tanum

>The error is: SQL: Column 'ACTID' is not found

>If I switch the order of the JOIN and ON statements, I get the error:

>If I have the source tables open before I issue the command, it works. All fields exist, and I can create the view in View Designer. Once I save and exit the designer, I can not edit it in View Designer because I get the error.

>Once the view is created, the source tables have to be open before I open the view.
