Hi,
I am a postgresql and stored procedures beginner and I
would like to know if the stored procedure I am trying to migrate
to plpgsql from MSSQL is correct.

Here 's the only table involved in the stored procedure:
create table ManufacturerOrders
(
     OrderNumber serial,
     SKU     int not null,
     Make    varchar(50) not null,
     Model   varchar(50) not null,
     Price   int not null,
     Status varchar(20) not null,
     primary key (OrderNumber)
);


Here 's the original MSSQL stored procedure:
create procedure UpdateOrder (@OrderNum int)
as
	set nocount on

	update ManufacturerOrders set Status = "Shipped" where
	OrderNumber = @OrderNum;

  	SELECT SKU, Price FROM ManufacturerOrders
	WHERE OrderNumber = @OrderNum
go

Here 's the plpgsql version i wrote:

CREATE FUNCTION UpdateOrder(INTEGER) RETURNS TEXT AS '
  DECLARE
   i_ordernum ALIAS for $1;
   r_SKUPrice RECORD;
  BEGIN
         update ManufacturerOrders set Status = ''Shipped'' where 
OrderNumber = i_ordernum;

         SELECT SKU, Price INTO r_SKUPrice FROM ManufacturerOrders WHERE 
OrderNumber = i_ordernum;
         return r_SKUPrice;

  END;
  ' LANGUAGE 'plpgsql';

I would like to know especially if the RETURNS statement is correct here
and if i can give a name to the record r_SKUPrice columns .

Thanks in advance,
Bengali
