请看以下代码
我做了一张数据表,想将p p1 p2 p3 参数化
edit_set("p",ddt_val(DB_path, "Price Within Quota(rial)"));
edit_set("p1",ddt_val(DB_path, "Price for Extra Fuel Rate1(rial)"));
edit_set("p2",ddt_val(DB_path, "Price for Extra Fuel Rate2(rial)"));
edit_set("p3",ddt_val(DB_path, "Price for Extra Fuel Rate3(rial)"));
为什么最后老是没有任何值输入到对应的p p1 p2 中去呢?
