Hi Michael,
this is the generated sql:
1) IT IS using STUDENT:
I am new to Discoverer (have Microsoft Access background0 and
have noticed that Discoverer will throw in a table that i have not EXPLICITLY asked for.
Pls advise
2) I tried the trick of using MA twice in OR condition and am getting error msg when try to do OR conditio
of ambiguous error.
