Are you copying the rows to another table in the same Oracle instance? What I mean is this in the same Oracle instance? If so, the TO user needs SELECT privilege on the table of the FROM user. Then you can issue the following SQL:

INSERT INTO USER2.MYTABLE (SELECT * FROM USER1.MYTABLE)

If the USER2 table is empty you can drop it, and create the table to guarantee exact duplication:

CREATE TABLE USER2.MYTABLE AS SELECT * FROM USER1.MYTABLE
