Hi,
Here is an example that i am helpful.
In the example , I am using a table 'table_name' which contains columns like
assign_attribute1
assign_attribute2
assign_attribute15
Now I will pass any number from 1 to 15 to the function.
create or replace procedure pass_col_number(v_number varchar2) as
v_sql varchar2(2000);
v_assign_attribute1   varchar2(150);
begin
v_sql := 'select  assign_attribute'||v_number||'  from  table_name where person_id = 1345';
execute immediate v_sql into v_assign_attribute1;
dbms_output.put_line('v_assign_attribute1='||v_assign_attribute1);
end;Edited by: Sreekanth Munagala on Dec 18, 2008 1:18 AM
