Question

*对不起，我犯了一些错误和粗暴的举止。

现在我尝试使用AlaSql制作销售汇总报告，继承我的代码：

table {border:1px solid black}

<script src="https://cdn.jsdelivr.net/alasql/0.3/alasql.min.js"></script>
<p>ROLLUPTEST()</p><div id="res1"></div>

{ Area: "Area 1", Shop: "Shop 1"  , Val: 5 },
{ Area: "Area 1", Shop: "Shop 2"  , Val: 20 },
{ Area: "Area 1", Shop: "SUBTOTAL", Val: 25 },
{ Area: "Area 2", Shop: "Shop 1"  , Val: 25 },
{ Area: "Area 2", Shop: "Shop 2"  , Val: 40 },
{ Area: "Area 2", Shop: "SUBTOTAL", Val: 65 },
{ Area: "ALL"   , Shop: "TOTAL"   , Val: 90 },

我希望在表格中显示价值摘要。

            var x = Request.Files;
            var y = Request.Form["model"];

但是当运行它时，调试器会显示“脚本错误”。浏览器中没有表格显示。

我猜AlaSql不支持GROUPING功能。如果有人知道这件事，请告诉我。

不，AlaSQL仅在另一个上下文中知道GROUPING keyword，即在GROUPING SETS中：

GROUP BY GROUPING SETS(Area, Shop)

如果您的Area和Shop字段为非空，则可以按如下方式处理：

SELECT   CASE WHEN Area IS NULL THEN "ALL" ELSE Area END AS Area, 
         CASE WHEN Shop IS NULL THEN 
            CASE WHEN Area IS NULL THEN "TOTAL" ELSE "SUBTOTAL" END 
            ELSE Shop
         END as Shop,
         SUM(Val) AS Val 
INTO     HTML("#res1", {headers:true}) 
FROM     ?
GROUP BY ROLLUP(Area,Shop)

AlaSql支持GROUPING功能吗？
