Oracle Replace function

Question

I need to replace the Table1\'s filed values from Table2\'s values while select query.

Eg:

Table1:

Org                  Permission
--------------         


        

Answer 1

In Oracle you can run this PL/SQL block and it will do all the work:

begin
  for x in (
    select permission, descr from table2
  ) loop
    update table1 set permission = replace(permission, x.permission, x.descr);
  end loop;
  commit;
end
/

I used this script to create a schema:

create table table1(
  org varchar2(100),
  permission varchar2(1000)
);

create table table2(
  permission varchar2(100),
  descr varchar2(1000)
);

insert into table1(org, permission) values ('Company1', '1,3,7');
insert into table1(org, permission) values ('Company2', '1,3,8');
insert into table2(permission, descr) values ('1', 'Read');
insert into table2(permission, descr) values ('7', 'Execute');
insert into table2(permission, descr) values ('8', 'Delete');
