Question

下面的语句将会执行。但是，我想要 wShipment.Volume 除以 1728 并导出该结果。

例如wShipment.Volume为3456，则应将结果2输出到报表中。

OUTPUT TO \tsclient\U\All_Orders_item.csv.

FOR EACH r4_wms.wShipmentDet NO-LOCK,

FIRST r4_wms.wShipment OF r4_wms.wShipmentDet NO-LOCK where wShipment.shipmentNO>6500 and wShipmentDet.Owner="MIDEAUS",

FIRST r4_wms.wOrder OF r4_wms.wShipmentDet NO-LOCK,

FIRST r4_wms.wOrderline OF r4_wms.wShipmentDet NO-LOCK
 BY wShipment.ShipmentNo DESC:

EXPORT DELIMITER ","

           wOrder.OrderNo

           wShipment.Volume

           wShipment.Weight SKIP.   

 END.

 OUTPUT CLOSE.

Answer 1

如果您只想除以 1728，可以直接在 EXPORT 语句中进行：

wShipment.Volume / 1728

但是“1728”听起来像是您在寻找立方英尺 (12 x 12 x 12)。如果您需要体积的最小整数立方英尺，您可以这样计算：

DEFINE VARIABLE RoundedVol AS INTEGER NO-UNDO.

RoundedVol = TRUNCATE(wShipment.Volume / 1728, 0).
IF wShipment.Volume MOD 1728 > 0 THEN 
    RoundedVol = RoundedVol + 1.

然后将 RoundedVol 添加到 EXPORT 语句中。它会给你任何分数四舍五入的立方英尺。因此，对于 1729 卷，您将得到 2.
