Hi list,

I have this function it's compile ok but doesn't return any value:

CREATE OR REPLACE function f_get_desc2

     (table_name in varchar2,
      code_column_name in varchar2,
      code_id in varchar2)
      return varchar2
   is
      return_desc varchar2 (100) ;
          DESC_VAL VARCHAR2(100);

   begin
   SELECT COLUMN_NAME INTO DESC_VAL FROM USER_TAB_COLUMNS ?????    WHERE TABLE_NAME =':table_name' AND COLUMN_ID = 2 ; ????
-- here I want to get the description column name from
user)tab_columns.....then get the value based on the ID

      execute immediate 'select ' || DESC_VAL ||
         ' from ' || table_name || ' where ' || code_column_name ||
         ' = :id' into return_desc using code_id ;
      return return_desc ;

   end ;
/

I pass column_name ,code & value of the code to function then get the name of description Column from table_name and finally get the description based on table_name,descripton column & value, BUT doesn't return any value I am not sure but the ?mark lines doesn't return any value.

Thanks for your help.
