I'm not sure what you mean by setting the value by an update statement.

The "update" sections allow you to set attributes. This is documented.

Could you give an example of how to do this? Ideally, I would like to save it if it exists, and if not, just insert a NULL or empty string.

See the existing SQL accounting queries. They do this lots. See also "man unlang". Look for "Conditional Syntax". Alan DeKok.
