Question

我一直致力于查询，如下所示。（我确实使用VB.NET 2010而DB是MsAccess 2007）

SELECT 
    sale_details.invoiceno AS sale_details_invoiceno, 
    sale_details.product_code,
    sale_details.qty, sale_details.totalkg, sale_details.Rate, sale_details.subtotal,     
    sale_head.invoiceno AS sale_head_invoiceno, sale_head.suppliername, sale_head.invoicedate
FROM 
    sale_head 
INNER JOIN 
    sale_details ON sale_head.[invoiceno] = sale_details.[invoiceno]
WHERE 
    (((sale_head.suppliername)='Ramkrishna Creation'));

显示结果如下：

sale_details_invoice|product_code|qty |totalkg|Rate |Subtotal|Sale_head_invoice|suppliername          |invoicedate

我想打破并显示发票号码的总计。在SQL或VB.NET DataGrid Control中有没有办法显示如下的结果？

sale_details_invoice|product_code|qty |totalkg|Rate |Subtotal|Sale_head_invoice|suppliername          |invoicedate

5026                | M 1010     | 10 | 2.5   | 270 |   675  |5026             |Ramkrishna Creation   | 18/07/2014

有没有办法通过SQL或VB.NET DataGrid控件来解决这个问题？我一直在寻找解决方案，但我还没有得到它，请大家，如果你知道，请告诉我

Answer 1

您可以在VB中循环计算数据，或者让SQL选择总计。对于后者，您将再次查询相同的数据：

SELECT 
  sd.invoiceno AS sale_details_invoiceno, 
  sd.product_code,
  sd.qty, 
  sd.totalkg, 
  sd.Rate, 
  sd.subtotal,     
  sh.invoiceno AS sale_head_invoiceno, 
  sh.suppliername, 
  sh.invoicedate
FROM sale_head sh
INNER JOIN sale_details sd ON sh.invoiceno = sd.invoiceno
WHERE sh.suppliername = 'Ramkrishna Creation'
UNION ALL
SELECT 
  sd.invoiceno,
  'TOTAL',
  null, 
  null, 
  null, 
  SUM(sd.subtotal),     
  null, 
  null, 
  null
FROM sale_head sh
INNER JOIN sale_details sd ON sh.invoiceno = sd.invoiceno
WHERE sh.suppliername = 'Ramkrishna Creation'
GROUP BY sd.invoiceno 
ORDER BY sale_details_invoiceno, IIF(product_code = 'TOTAL', 1, 0);

如何在sql查询中分隔行组
