Question How to repair a corrupt table ?
<Newbie>

After a backup error and using the following logfiles I discovered that a table is corrupt into my database. The problem is that I cannot export it (the export request never stop, I aborted it after more than 30 min)
Now I just wanna now what a hell is going wrong with this table, why I cannot nor export nor reorg it, and more than all, how I can repair it...
Thanks for your help

Re: How to repair a corrupt table ?

finally I did it... And as you can imagine it was so easy: all I've got to do was a basic reorg. I don't know why it did not work before I made reorg on specific tables and backup command is absolutely OK !!!
Thanks to sathyaram_s for his (her ?) support...
