I have a table like this

SerialNumber    MyDecision    FathersDecision       GrandFatherDecesion
-----------------------------------------------------------------------------------
1                                                                       GoToSchool
2                                             GoToNeighbors    GoToColony
3                      GoToFriends     GoToPeople         GoToAll
4                                              EatEnough          EatWell

I want to make a query that selects all of the above 4 fields as they are right now and i want to add another field that id called as SuperDecesion, it should have MyDecesion, if it is blank then, FathersDecision, if FathersDecision is also null then it should contain GrandFatherDecesion, in short the 5thcolumn should look like this in the aboce specific example

SuperDecesion
-----------------
GoToSchool
GoToNeighbors
GoToFeiends
EatEnough

can some one make exact query, i know it will have IF condition in query but i failed to make it. Please help ASAP.

Try this:
Select *, iif(nz(trim(mydecision))<>"", mydecision, iif(nz(trim(fathersdecision))<>"", fathersdecision, grandfathersdecision)) as SuperDecision From table

for me

Select *, iif(nz(trim(mydecision))<>"", mydecision, iif(nz(trim(fathersdecision))<>"", fathersdecision, grandfathersdecision)) as SuperDecision From table
 
this is not working, but if you eliminate {as SuperDecision} from the query then it works fine and names the field as Expr1000, if i donot eliminate it then it asks me value of SuperDecision.Expr1000

is it working with you ?
