Hi Everyone,

I am having an access database with RegistrationNo ,Barcode, VehicleModel, FuelType, RegistrationDate, InsuranceDate and PUCDate columns.

I am trying to execute a query
"select RegistrationNo as RegistrationID, Barcode, VehicleModel, FuelType, RegistrationDate, InsuranceDate, PUCDate from VehicleMaster where cdate(PucDate)>=cdate(format('01-07-2012',"dd-mm-YYYY")) and cdate(PucDate)<=cdate(format('01-07-2012',"dd-mm-YYYY")) order by Barcode"

But i am getting an error "Invalid use of Null" because there is one null value in PUCDate column.

Can anyone help me how to solve this error

Thanks in advance

Solution 1

you need the Access equivalent of SQL ISNULL(a,b)[^] which is IIF(ISNULL(column),0,column)[^]

Can also use "Nz(a,b)" :)
