Need a procedure or a pl/sql block

Question

Dear all,
I have a 2tables emp_address, address as below:
create table emp_address(emp_id varchar2(10),address varchar2(100));
Insert into EMP_ADDRESS
(EMP_ID, ADDRESS)
Values
('101', 'street1     fremont     CA     94538');
Insert into EMP_ADDRESS
(EMP_ID, ADDRESS)
Values
('102', 'street2     fremont     CA     94537');
COMMIT;
create table address(emp_id varchar2(10),street varchar2(20),city varchar2(15),state varchar2(10),zip varchar2(10));
The data in emp_address is as below:
emp_id address
101 street1     fremont     CA     94538
102 street2     fremont     CA     94537
now i have to read the data from emp_address and split the data of address column and save that data into address table like as below
emp_id street city state zip
101 street1 fremont ca 94538
102 street2 fremont ca 94537
So i need to write a procedure to get this. i am very new to Pl/sql. Could any one can help me to get this.
Thanks in adavnce

Answer 1

try out this,
create or replace procedure address as
Cursor c1 is select * from emp_address;
Begin
for r1 in c1 loop
insert into address values(r1.emp_id,substr(r1.address,1,instr(r1.address,' ',1,1))
,substr(r1.address,instr(r1.address,' ',1,1),instr(r1.address,' ',1,2)-instr(r1.address,' ',1,1))
     ,substr(r1.address,instr(r1.address,' ',1,2),instr(r1.address,' ',1,3)-instr(r1.address,' ',1,2))
     ,substr(r1.address,instr(r1.address,' ',1,3)));
end loop;
End;or as simple SQL stmt
insert into address values(emp_id,substr(address,1,instr(address,' ',1,1))
,substr(address,instr(address,' ',1,1),instr(address,' ',1,2)-instr(address,' ',1,1))
     ,substr(address,instr(address,' ',1,2),instr(address,' ',1,3)-instr(address,' ',1,2))
     ,substr(address,instr(address,' ',1,3)));
