O.k. I renamed oldreport_2002_12_08.MYD and oldreport_2002_12_08.MYI to tempo.MYI and tempo.MYD.
Then I ran: CREATE TABLE oldreport_2002_12_08 as select * from oldreports where 1=2; And now I have: $ls -lh -rw-rw---- 1 mysql mysql 12G Jun 20 2003 tempo.MYI -rw-rw---- 1 mysql mysql 8K Feb 16 15:37 oldreport_2002_12_08.frm -rw-rw---- 1 mysql mysql 17G Jun 19 2003 oldreports.MYD -rw-rw---- 1 mysql mysql 10G Dec 5 19:32 oldreports.MYI -rw-rw---- 1 mysql mysql 8K Jun 20 2003 oldreports.frm -rw-rw---- 1 mysql mysql 21G Jun 20 2003 tempo.MYD -rw-rw---- 1 mysql mysql 1K Feb 16 15:37 oldreport_2002_12_08.MYI -rw-rw---- 1 mysql mysql 0B Feb 16 15:37 oldreport_2002_12_08.MYD Now I just have to get the data in tempo.MYI and tempo.MYD into the newly generated oldreport_2002_12_08.MYI and oldreport_2002_12_08.MYD Thanks for all your help, Cam ---------------------- On Mon, 2004-02-16 at 14:23, Bing Du wrote: > Yes, that would create a new table (only the oldreport_2002_12_08.MYD file > will be zero, the MYI and frm files are not) which has exactly the same > definition of the table oldreports but without any data in it. > So make sure you have a good copy of both oldreport_2002_12_08.MYD and > oldreport_2002_12_08.MYI.
