Can crystal allow to call procedure from a procedure?

Question

Hi,
Currently I am using crystal to call a procedure. The procedure will call another procedure by doing some insert statement in the second procedure. I heard that this could not be work, is that true? Is there any other way to do?

Answer 1

here is an example of a procedure calling another procedure to do the insert:
SQL> create table test_tab
  2  (id number);
Table created.
SQL> create or replace procedure procedure_1 as
  2  begin
  3    insert into test_tab
  4    select nvl(max(id),0)+1 from test_tab;
  5  end;
  6  /
Procedure created.
SQL> create or replace procedure procedure_2 as
  2  begin
  3    -- now we call the other procedure
  4    procedure_1;
  5    commit;
  6  end;
  7  /
Procedure created.
SQL> execute procedure_2;
PL/SQL procedure successfully completed.
SQL> select * from test_tab;
        ID
         1
SQL> execute procedure_2;
PL/SQL procedure successfully completed.
SQL> select * from test_tab;
        ID
         1
         2
