>Hi all,
>Every 2-3 weeks I load 0.5-1.5 million rec into server table and delete "expired" records. I delete records from server table using BCP+Fox solution (DROP INDEX for all of them, BCP the whole table (3-5 mln rec) out, APPEND FROM tblOld.txt FOR myConditions to Fox table, COPY TO tblNew.txt, TRUNCATE server table, BCP in, CREATE INDEX ).
>It works good enough and using BCP+Fox I avoid transaction log nightmare that kills all SQL Server solutions I tried, but I am still interested in "Server only" solution and wondering how others deal with such problem.
>TIA and Happy New Year!

Are the records being deleted coming only from the records you load every 2 to 3 weeks? If so, [at least in Oracle], you can use a BEFORE INSERT TRIGGER to prevent non-qualifying records from being inserted. Any other records already in the table would have to be deleted using the DELETE FROM command.
