What Is The Access VBA NZ Function

The Access VBA NZ function allows you to test for values with zero length.

It is unique with Access, as far as I know, no other language has this type of function, and you’ll have to make your own.

If you want to check if a variable is blank, you should check the length (contents) of the variable:

If variable = {blank} then
end if

What is NZ in access?

Like I already stated, the Access NZ function checks for blank (null) values.

It also substitutes a value if the variable is blank.

NZ(var,”not blank var”)

This is useful when you are running an append query, and some of the values you are trying to insert are blank.

insertthis: nz(field, “blank val”)

Is null in VBA Access?

If you don’t want to use the NZ function, you could just use the IsNull function. You just have to do a little more work, but it basically works the same way.

if isnull(variable) then
variable=”not blank”
end if

How do I use IIF in access?

The IIF is also unique to Access. It stands for “immediate if”. Anyway, Excel uses just basic “If”, but Access has to be different:

iif(variable = “”, “blank”, “not blank”)

What does NULL mean access?

NULL in Access means “blank”

Any questions?
