Oracle: Executes a PL/SQL statement, and returns the variable of bind variable :1.

PostgreSQL: Performs a pl/pgsql function or procedure call. The caller must perform a select query that returns the value of the function.

Examples:

    # Oracle:
    db_exec_plsql delete_note {
        begin  note.del(:note_id);  end;
    }

    # PostgreSQL:
    db_exec_plsql delete_note {
        select note__delete(:note_id);
    }
    

If you need the return value, then do something like this:

    # Oracle:
    set new_note_id [db_exec_plsql create_note {
        begin
        :1 := note.new(
          owner_id => :user_id,
          title    => :title,
          body     => :body,
          creation_user => :user_id,
          creation_ip   => :peeraddr,
          context_id    => :package_id
        );
        end;
    }]

    # PostgreSQL:
    set new_note_id [db_exec_plsql create_note {
        select note__new(
                         null,
                         :user_id,
                         :title,
                         :body,
                         'note',
                         now(),
                         :user_id,
                         :peeraddr,
                         :package_id
                         );
    }]
    

You can call several pl/sql statements at once, like this:

    # Oracle:
    db_exec_plsql delete_note {
        begin
        note.del(:note_id);
        note.del(:another_note_id);
        note.del(:yet_another_note_id);
        end;
    }

    # PostgreSQL:
    db_exec_plsql delete_note {
        select note__delete(:note_id);
        select note__delete(:another_note_id);
        select note__delete(:yet_another_note_id);
    }
    

If you are using xql files then put the body of the query in a yourfilename-oracle.xql or yourfilename-postgresql.xql file, as appropriate. E.g. the first example transformed to use xql files looks like this:

yourfilename.tcl:

    db_exec_plsql delete_note { }

yourfilename-oracle.xql:

    <fullquery name="delete_note">      
      <querytext>
        begin
        note.del(:note_id);
        end;
      </querytext>
    </fullquery>

yourfilename-postgresql.xql:

    <fullquery name="delete_note">      
      <querytext>
        select note__delete(:note_id);
      </querytext>
    </fullquery>

Switches:

-dbn (optional)

The database name to use. If empty_string, uses the default database.

Parameters:
