Using NULL as a field value

Using NULL as a field value

The string NULL has a particular role in scripts and is a reserved word.

A string containing the term NULL should not be used as a field value in import set transform maps or anywhere in the First name or Last name fields. The reserved word is NULL in all capital letters. A field with the value Null or null, for example, is acceptable. NULL should only be used to clear out a particular field.
