Data Access and Property MethodsData Access and Property Methods

Example:

dal.set.property("tdsls400", ttdsls400, "tdsls400.amnt", tdsls400.amnt + tdsls401.amnt, DAL_UPDATE)

dal.update("tdsls400", ttdsls400, ret, true, db.retry)

Data Access Methods

• dal.new()• dal.update()• dal.destroy()

Property Methods

• dal.set.property• dal.get.property.flag()

Non interactive database modifications Non interactive database modifications

• Business method • Programmed in the dal of the most relevant table• Activated from UI script or DAL• Activated by means of dal.start.business.method

Non interactive database modifications Non interactive database modifications - Example (1)- Example (1)

Purchase Order Headers(oes022)

Items(oes020)

Purchase Order Lines(oes023)

When a new order line is saved (table oes023), the Stock on Order field in the Items table (oes020) is updated automatically.

Example: The following order line is saved:Purchase Order: 105. Position: 20Item: 101010Ordered Quantity: 25

At the moment of saving this order line, automatically, the Stock on Order field (table oes020) for item 101010 is increased by 25.


DAL Purchase Order Lines table (ppoes023):

function extern long after.save.object(long mode){

if mode = DAL_NEW then dal.start.business.method(”ppoes020",

”update.stock.on.order", ret,ppoes023.item,ppoes023.oqua)

endif

return(0)}


DAL Items table (ppoes020):

function extern long update.stock.on.order( domain ppoes.item order.item, domain ppoes.quan order.quan )

{long ret

select ppoes020.ostk from ppoes020 for updatewhere poes020._index1 = {:order.item}selectdo

dal.set.property(”ppoes020", tppoes020, ”ppoes020.ostk", ppoes020.ostk + order.quan, DAL_UPDATE)

dal.update(”ppoes020", tppoes020, ret, true, db.retry)endselect

return(0)}
