Well, it worked. I guess either my brain or my PC was slow in getting back from vacation.

RE: Update to Null
As long as the field allows nulls, then this shouldn't be a problem - although I'm speaking from SQL Server experience and not Oracle...

Re: Update to Null
This will work for Oracle (or any other RDBMS) provided the column in the table is set to accept NULLs.

RE: Update to Null
UPDATE Employees SET Age = NULL WHERE Id = 2 This has always worked fine for me using MS SQL 7.0 and MS Access. Rick -Original Message- From: David Shadovitz [mailto:[EMAIL PROTECTED]] Sent: Tuesday, January 02, 2001 9:31 PM To: CF-Talk Subject: OT: Update to Null 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.
