>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!

Have you tried SQL Passthru?
nhandle = sqlconnect("mydatasource")
? sqlexec(nhandle, "Delete from mytable where expired")
? sqldisconn(nhandle)

I have no idea what the performance will be like, but it works pretty fast on SQL Anywhere.
