Re: Mod or delete record if only one field matches, and add new record if one specific field does not exist

>There's no "magic" statement to do everything in one go.
Situation is made for INSERT ... ON DUPLICATE KEY UPDATE

You need to define a UNIQUE INDEX on the hostname field.
Then you can INSERT, unless the hostnameT already exists, then you can update whatever fields you want.

Good luck,
Barry.
