Re: query-based update failed

Hi Chris,
Could you please clarify a bit more on what you mean by "checking each
record in your recordset to see if it is in your database table at that
time"?

I mean that you need to check if the record in your recordset is existed in
your database table. If it does not exist, it is impossible to update it.

"And primary key EmpID has been set correctly before you call EmpRs.Update
method"? How can we determine if the key has been set correctly?
I had thought that you knew the EmpID before the update otherwise how did
you know which record should be updated.
Maybe you need to run a query like the following before you execute the
update:
IF EXISTS(SELECT * FROM <tablename> WHERE EMPID=<empid>)
BEGIN
UPDATE <tablename> SET ..... WHERE EMPID=<empid>
END

Hope this helps. If you have any other questions or concerns, please feel
free to let me know.

Best regards,
Charles Wang
