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
true
else
false
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.

ex:
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=”blank”
else
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:

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

What does NULL mean access?

NULL in Access means “blank”
