May be instead of

SELECT SUM(IM.TRS)TRS, SUM(IM.INCOME)INCOME, SUM(IM.OUTGO)OUTGO

should be just

SELECT SUM(IM.TRS), SUM(IM.INCOME), SUM(IM.OUTGO)

?

 

The JOIN - I alway specify what kind of join I want, such as LEFT OUTER JOIN, because I am never sure, what is the default 🙂

I don't know IB nor do I know the result of the IM JOIN WH but I don't like the "SUM(IM.TRS)TRS"

I would write this like ISNULL( SUM( ISNULL(IM.TRS, 0) ), 0) AS TRS

Hi,

 

Since you already know the values of :TRS, :INCOME and :OUTGO you can check for nulls before entering your update.

 

SELECT ....  INTO :TRS,:INCOME,:OUTGO;

 

IF TRS is NULL then TRS = 0;
if INCOME IS NULL then INCOME = 0;
if OUTGO IS NULL then OUTGO = 0;
STOCK = TRS + INCOME - OUTGO;

 

UPDATE ITEMS

       SET TRS=  :TRS,
             INCOME = :INCOME,
            OUTGO=  :OUTGO,
           STOCK= :STOCK
     WHERE  ITEMNO=:ITMNO;     
END

 

I haven't checked the syntax, but you get the idea.

            OUTGO=  :OUTGO,
           STOCK= :STOCK
     WHERE  ITEMNO=:ITMNO;     
END

 

Warning. This changes the SP fundamentally where negative numbers were ignored.
