How to auto assign a number to some data using PL/SQL

Question

Hi,
Assume that i have a few lines of data...
How do i auto assign number to the data without hardcoding it?
In this instance, i want p_id to be auto-generate...
create or replace procedure insert_file
p_id number,
p_file_type varchar2,
p_file_name varchar2
)as
geor MDSYS.SDO_GEORASTER;
begin
insert into nyp_images values( p_id, p_file_type, sdo_geor.init('NYP_IMAGES_RDT') );
select image into geor from nyp_images where image_id = p_id for update;
sdo_geor.importFrom(geor, NULL, p_file_type, 'file', p_file_name);
update nyp_images set image = geor Where image_id = p_id;
end insert_file;
Thanks and regards,
Esther

In this case you could slightly change your procedure to
create or replace procedure insert_file (
  p_file_type     varchar2,
  p_file_name     varchar2,
  p_id        out number
  )as
  geor MDSYS.SDO_GEORASTER;
begin
  insert into nyp_images values( your_seq.nextval, p_file_type, sdo_geor.init('NYP_IMAGES_RDT') )
     returning image_id into p_id;
  select image into geor from nyp_images where image_id = p_id for update;
  sdo_geor.importFrom(geor, NULL, p_file_type, 'file', p_file_name);
  update nyp_images set image = geor Where image_id = p_id;
end insert_file;I highly reccommend you to take classes in this SQL and PL/SQL stuff or look for some external ressources that can guide you.
