In one line: update mytable set X = B*(minimum(A,C)-C)/(A-C)+D*(minimum(A,C)-A)/(C-A)
If A=C, the record will not be updated. That should also be like requested, but you get a division by 0 error.

I want MapInfo to compare column A and column C to decide whether to populate x with B or D. Basically something to the effect of: Update X with B if A<C or Update X with D if C<A....... Can someone please tell me if I am missing something?
