No of inputs differing

Question

Hi
I'm getting the table names as input and i have to do some DML operation based on the table names,
the DML operation is, i have to do a delete in that table and i have to do one insert in another
auditing table.
there are 40 tables, but sometimes i may have to do this operation for all the 40 tables, sometime
only for few tables, the number of inputs will be differing,
Can anyone suggest me how can i do this by using a single stored procedure that will act accordingly
irresepective of the number of inputs provided
Thank you
Mj

Answer 1

Ok lets talk about the DML operation. You have 2 DML
1. Delete
2. Insert
So for Delete is it a conditional delete. Do you have any where condition? Likewise for insert is it an conditional insert. Can you explain that.
If you have a way to handle that and your only problem is passing the table then you can do like this
SQL> create or replace procedure my_proc(ptablelist IN varchar2)
  2  as
  3  begin
  4     for i in (select trim(regexp_substr(ptablelist,'[^,]+',1,n)) str
  5                 from (select level n
  6                         from dual
  7                      connect by level <= length(ptablelist) - length(replace(ptablelist,','))+1))
  8     loop
  9             dbms_output.put_line(i.str);
10     end loop;
11  end;
12  /
Procedure created.
SQL> exec my_proc('TABLE1,TABLE2,TABLE3,TABLE4,MY_TABLE_123,YOUR_TABLE, WHATEVER_TABLE')
TABLE1
TABLE2
TABLE3
TABLE4
MY_TABLE_123
YOUR_TABLE
WHATEVER_TABLE
