Hi Tom,

In Unix db2 I am using the below query to clear the table.

db2 Query in Unix:

load from /dev/null of del replace into Schema.Tablename nonrecoverable;

What would be the best approach to do the same thing in Oracle.

I don't think delete will do the same thing. Correct me if I am wrong.

and Connor said...

truncate table T;

will empty the table without overhead (ie, it is not a delete, but more of a reset of the table).

truncate is DDL so it cannot be rolled back
