So he can do a select from the local database and insert in to the remote database, assuming that he can establish a connection to that machine... This would be faster that the HPL since he's skipping the unload process. He could do each table in parallel as well. That would be the *fastest* way. Well, actually there is a "faster" way, but it would require a tad more work, however it isn't worth the effort. -G __________________________________________________ _______________ Dave vs. Carl: The Insignificant Championship Series. *Who will win? http://clk.atdmt.com/MSN/go/msnnkwsp...001MSN38C07001 |
