I am curious - do you use FULL JOIN all the time? I usually use an inner join, and, perhaps in 10-20% of the cases, a LEFT JOIN, but I have never seen the need for a FULL JOIN.

BTW, you can make VFP code more readable, here on the UT, if you use the HTML code PRE, for pre-formatted text. This will preserver spaces. Click on "Reply" to see how I did it.

Regards,

Hilmar.

     trial!t1 ;
    FULL JOIN trial!t2 ;
   ON  T1.code = T2.t1code ;
    FULL JOIN trial!t3 ;
   ON  T2.t1code = T3.t2code ;
    FULL JOIN trial!t4 ;
   ON  T3.t2code = T4.t3code
