Merge doesn't do delete

All,

The 'Merge' command seems to be incomplete since it doesn't delete records that don't exist. The 'Merge' command only performs an update or insert. Isn't the purpose of the 'Merge' command to kind of make one table look like another one? Sure there will be times when only updating and inserting records is enough to keep the tables insync, but only if records aren't deleted from the source table. Any comments or suggestions on the best way to keep two tables in sync within the same database? Will I have to run two commands, one command will be the Merge to update and insert and a delete command that queries for keys that don't exist anymore in the source table?

Thanks,

John Cantu
