Re: Strange SQL error

What I don't understand, is that the following statement does work:

     c/exec sql  
     c+ Declare CR1 cursor for  
     c+  Select vendor,  
     c+         vdname,  
     c+         count(slip)  
     c+  From (  
     c+  Select fdvdcd as vendor,  
     c+         vdvnam as vdname,  
     c+         rfslip as slip  
     c+  From rflog, fldmst, isfile, vdmast  
     c+  Where (rfuser = :k1user) and  
     c+        (rftype = :type) and  
     c+        date(rftrdt) = date(:k1date) and  
     c+        isslip = rfslip and  
     c+        fdflno = isflno and  
     c+        fdlnno = isflln and  
     c+        vdvdcd = fdvdcd  
     c+  Union  
     c+  Select fdvdcd as vendor,  
     c+         vdvnam as vdname,  
     c+         rfslip as slip  
     c+  From rflog, fldmst, bofile, vdmast  
     c+  Where (rfuser = :k1user) and  
     c+        (rftype = :type) and  
     c+        rftype <> 'BI' and  
     c+        date(rftrdt) = date(:k1date) and  
     c+        boslip = rfslip and  
     c+        fdflno = boflno and  
     c+        fdlnno = boflln and  
     c+        vdvdcd = fdvdcd  
     c+       ) as table1  
     c+  Group by vendor,  
     c+           vdname  
     c+  Order by vendor,  
     c+           vdname  
     c/end-exec  
 

The difference might be that I'm now at a new client on V5R1M0, and the 
above was made on V5R3M0...

Or is this something completely different?

Well, if I'm not mistaken, selects in a where clause must be
sub-selects.  By definition, any select with a union operator is a 
full-select.
Part of the language definition.
