Sets a database field to null. This function will also overwrite a default value with null. If connected to something that is not a database field, it will behave like an empty sequence. Note the following:
•Connecting set-null to a different function will usually result in the other function not being called at all. Connecting set-null to a sequence function such as count will call the function with an empty sequence.
•Connecting set-null to filters and if-else conditions works as expected; fields are set to null. For filters, this means the "node/row" input.
•Using set-null as an input for a simpleType element will not create that element in the target component.
