You can use the Nz function to return zero, a zero-length string " "or another vba value when a Variant is Null. For example, you can use this function to convert a Null value to another value and prevent it from propagating through an expression.

If the value of the variant argument is Nullthe Nz function returns the number zero or a zero-length string always returns a zero-length string when used in a query expressiondepending on whether the context indicates the value should be a number or vba string. If the optional valueifnull argument is included, then the Nz function will return the value specified by that argument if the variant argument is Null.

When used in a query expression, the NZ function should always include the valueifnull argument. If the value of variant isn't Nullthen the Nz function returns the value of variant. The Nz function is useful for expressions that may include Null values. To force an expression to evaluate to a non- Null value even when it contains a Null value, use the Nz function to return zero, a zero-length string, or a custom return value.

You can often use the Nz function as an alternative to the IIf function. For example, in the following code, two expressions including date IIf function are necessary vba return the desired result. The first expression including the IIf function is used vba check the value of a variable and convert date to zero if it is Null.

In the next example, the Nz function provides the date functionality as the first expression, and the desired result is achieved in date step rather than date. If vba supply a date for the optional argument valueifnullthat value will be returned when variant is Null. By including this optional argument, you may be able to avoid the use of an expression containing the IIf function.

For example, the following expression uses the IIf function to return a string if date value of varFreight is Null. In the next example, the optional argument supplied to the Nz function provides the string to vba returned vba varFreight is Null.
