Problem with stored procedure and nested transactions

[<p.pierotti@xxxxxxx>]

Hi everyone,

I have problems with stored procedures introduced in version 11.

I do not understand how to create a nested transaction, in this semplified example:

 

create or replace procedure tst_prc(inout p_cod text) language plpgsql as $procedure$

begin

p_cod := 'a';

       begin

             update aziende set mail = 'asd@xxxxxxx' where id = 11; --1st update

             begin

                    update aziende set telefono = '0123456789' where id = 11; --2nd update

                    commit;

                    raise notice 'Inner';

             end;

             update aziende set telefono = '089' where id = 11; --3rd update

             --commit;

             rollback;

             raise notice 'Outer';

       end;

p_cod := 'b';

end;

 

$procedure$

 

 

The third update goes, rightly, in rollback; the problem is that the first 2 are committed.

 

I thought that the “BEGIN/END” block was used to create new transactions and that each of them could be managed individually.

 

What am I doing wrong?

 

Best regards.
