SQL & PL/SQL

Hi,

I am trying to insert records in the table using query similar to

insert into table1 (id, col1, col2)
select
sequence.nextval
t1. col1, t1.col2
from table t1;

I am getting following error

ORA-02287: sequence number not allowed here

Will you please let me know how to resolve this?

Regards
