Say please. How would you expect people to answer your question if you don't take time to write a proper question?

| Search the board like I did:
TRUNCATE is a DDL command, which implies an implicit commit.
- No rollback
- No explicit commit
- Changes are permanent
- No WHERE clause: that's not valid for DDL.
With TRUNCATE you reset the table's high watermark (the point up to where a table once has been filled). Oracle re-initialises this high watermark for the table, hence just 'forgets' the table's contents. No real physical delete takes place, the data location becomes available.
If there are dependent tables (through FKs), truncate will result in an error...
Search this site:http://asktom.oracle.com ( and bookmark it!!!).
