Inserting data into one table using another table

Question

Hi i have 2 tables
CREATE TABLE N_SET
N_ST_ID NUMBER(38) NOT NULL, ---- PK
N_ST_NM VARCHAR2(50 BYTE) NOT NULL,
N_ST_DSC VARCHAR2(200 BYTE),
DFTID NUMBER ------ FK
CREATE TABLE RZ
NST_ID NUMBER(38) NOT NULL, ---- FK
RID NUMBER(38) NOT NULL, --- PK
RNM VARCHAR2(30 BYTE) NOT NULL
I entered the data into the N_SET table using sequence in column N_ST_ID (using procedure)
Now i need to enter the data into RZ table where NST_ID should contain the value of N_SET.N_ST_ID
so for this i've written another procedure
but confused how to write the select statement to retrieve the above condition..
Could you help me in this please...

Hi,
I have a table Target whose structure is
create table employee
id VARCHAR2(20),
name VARCHAR2(20),
employee_seq NUMBER not null
-- Create sequence
create sequence test_seq
minvalue 1
maxvalue 999999999999999999999999999
start with 5
increment by 1
nocache
cycle;
create table emp
id VARCHAR2(20)
name VARCHAR2(20)
INSERT INTO emp
( id, name )
VaLUES ( '100','test1');
commit;
INSERT INTO emp
( id, name )
VaLUES ( '100','test2');
commit;
i have to insert into the TARGET table the fsa value from
SOURCE table along with the sequence number using sequence test_seq.nextval.
INSERT INTO employee
( id, name, employee_seq )
SELECT id, ename, ( select test_seq.nextval from dual )
FROM emp ;
