Is it possible to UPDATE the value of a numeric field to NULL?
Here's the scenario, which must be common:
The records of the Employees database table are displayed in an HTML
table, with an Edit and Delete button in each row. The user clicks Edit
to display a particular record in an editable form. If the user clears
the Age field and submits the form, what would the SQL UPDATE statement
look like?
I don't think this works:
UPDATE Employees
SET Age = NULL
WHERE Id = 2
I could test on FORM.Age and then do "SET Age = -1" if no age was
specified, but I'd rather not.
Thanks.
