UOM Convertion Rate API

计量单位转换API

set serveroutput on;
Declare
v_Rate Number(30,23);
v_itemid number default 2036;
Begin
v_rate := INV_CONVERT.INV_UM_CONVERT (
 ITEM_ID => v_itemid,
 PRECISION => 10,
 FROM_QUANTITY => 1,
 FROM_UNIT => '米',
 TO_UNIT => '吨',
 FROM_NAME => NULL,
 TO_NAME => NULL
 );
dbms_output.put_line('Rate :' ||v_rate);
end;

计算结果表示： 1 米(From_Unit) = Rate * 吨(To_Unit)

Precision为转换率的小数位精度。
