I'm not sure what your proc or table looks like. I'll use the following as an exampleTable: New_ClientsCols: Client_ID Int Client_Name Varchar(50) Company_Name Varchar(50) Date_Added DatetimeAdd the followingAlter table New_Clientsadd Mail_Sent tinyint
As part of your Mail Sending ProcUpdate New_ClientsSet Mail_Sent = 1 from New_Clients Where Client_ID = @Client_ID --(Your Identifie)
The next time your Mail_Proc runsInclude the FollowingSelect *from New_ClientsWhere Mail_Sent = '0'
Then it will select only the NEW Clients (Clients added since last update)You can't teach an old mouse new clicks.
