I am hoping that I can do this with one query, I have a table, "Domains" with 3 columns accountID, domainID, mailname
what I am trying to do is find all accountID's for "domainID" of 12345 and see if a second row with "domainID" of 54321 exists for that "accountID,mailname". If it doesn't exist, I want it to insert another row with the same accountID and mailname, but with the second (54321) domainid. Any help would be appreciated. Thanks Steve
