MS Access上溢-处理除以0

Question

I have the following expression in an MS Access Query, where some of these values can be null and despite the cast to a Decimal and the Not Zero (NZ) function, I still get an overflow error.

Sum(Cdec(Nz([TotalPrice]/([tbl_ArticlesPerOrder]![Amount]*[Total])*[tbl_ArtikelRemoveFromSawList]![Amount]),0))

EDIT: Removing the TotalPrice division removes the overflow. So I suspect a division by 0. Any way to deal with that?

Answer 1

I would try to see if you can build an IFf statement within your sum to handle the division by zero.

eg

IIf([tbl_ArticlesPerOrder]![Amount]*[Total])=0,0,[TotalPrice]/([tbl_ArticlesPerOrder]![Amount]*[Total])
