Dynamic selection of tables

Question

Hi
Is it possible to create a dynamic selection of tables in the 'from' clause.
Thanks in advance

Answer 1

Hi,
Thanks for the reply.
I have two tables. Currently in our existing production system we have two different procedures for example say, P1 and P2. These procedures have the same logic except that the data is retrieved from two different tables.
I felt that if there is a possibility to select data from the tables dynamically then i could just use one common procedure and pass the tables as parameters to that.
To make it more clear, please see the following.
I have two tables , say T1, T2.
I have two procedures P1, P2 in one package.
P1 procedure
Procedure P1 is
cnt number := 0;
Begin
select count(*) into cnt from T1;
if cnt = 0 then
   IF GVAR.T1_RecordNbr <= '1'  -- GVAR  is Global Variable package
            THEN
               IF NAME_IN('T1.col_name') IS NULL
               THEN
                  display_msg('Error');
               END IF;
  end if;
end if;
end;

P2 procedure
[pre]
Procedure P2 is
cnt number  := 0;
Begin
select count(*) into cnt from T2;
if cnt = 0 then
   IF GVAR.T2_RecordNbr <= '1'
            THEN
               IF NAME_IN('T2.col_name') IS NULL
               THEN
                  display_msg('Error');
               END IF;
   end if;
end if;
end;

Now I want to write only one procedure and just change the table names dynamically. Could you please suggest.
