Hi ,
I have created this function to remove UserDataAccountid
from both tables
UserAccountDetails and UserAC 
CREATE OR REPLACE FUNCTION DeleteUserData(ACDetailsID int[])
RETURNS void AS $$
DECLARE _id int;
BEGIN
  -- postgresql has no table type, use a int array instead
  FOR _id IN array_lower(ACDetailsID,1) .. array_upper(ACDetailsID,1)
  LOOP
      DELETE FROM UserAccountDetails WHERE UserDataAcountId=
_id;
      DELETE FROM UserAC WHERE UserDataAcountId= _id;
    END;
  END LOOP;
  EXCEPTION WHEN OTHERS THEN
    RAISE WARNING 'some issue %', SQLERRM;
END;
$$ LANGUAGE plpgsql;
 
Now I am calling this function to delete userdataacountid
from both tables, say i have a user with userdataacountid '5', how can i delete
this user by calling this function , i have tried 

select DeleteUserData(5);
and
select * from DeleteUserData(5);

its not working ,
thanks

I would guess that the error you're getting is:

ERROR:  function deleteuserdata(integer) does not exist
LINE 1: select DeleteUserData(5);
               ^

This is happening because your function takes an array, not a single
integer.  PostgreSQL can automatically cast from a string to an array if
the string is properly formatted:

select DeleteUserData('{5}');

Hope this helps.
