我正在使用此查询创建 HTML 表并通过电子邮件发送。 仅当“组 ID”和“总交易总和”列具有相同值时，是否可以合并单元格以提高可读性？ 下面是我想要得到的结果

CREATE TABLE #list (GroupID int,AccountID int,Country varchar (20),AccountTransactionSum int)

Insert into #list

(1,37843,'France',1490),
(2,97348,'United Kingdom',770)

对于 Siggemannen 的非常好的答案，我只想添加一种替代方法来处理 xquery 中的那些 td，

SELECT  GroupID, 
        AccountID, 
        Country, 
        AccountTransactionSum,
        TotalTransactionSum = sum(AccountTransactionSum) over (partition by GroupID),
        rowspan = COUNT(*) OVER(PARTITION BY GroupID),
        display = CASE WHEN lag(GroupID) OVER(ORDER BY GroupID,AccountID) = GroupID THEN 'display:none' ELSE '' END
FROM #list

定义 rowspan 和 display 后，您可以在 xquery for 循环中使用它们

for $row in /root/row
let $pos := count(root/row[. 
 {$pos}
 {data($row/GroupID)}
 {data($row/AccountID)}
 {data($row/Country)}
 {data($row/AccountTransactionSum)}
 {data($row/TotalTransactionSum)}

这是一个很好的问题，因为我不知道 xquery 可以发挥这种魔力！ 这就是我想到的：

DROP TABLE #list
go
SELECT  *
INTO    #list
FROM    (
VALUES 
(1,18754,'United Kingdom',110),
(1,24865,'Germany',265),
(1,82456,'Poland',1445),
(1,98668,'United Kingdom',60),
(1,37843,'France',1490),
(2,97348,'United Kingdom',770)
) t (groupid,accountid, country, AccountTransactionSum)

DECLARE @xmlBody      XML   
SET @xmlBody = (SELECT  (SELECT GroupID, 
                                AccountID, 
                                Country, 
                                AccountTransactionSum,
                                TotalTransactionSum = sum(AccountTransactionSum) OVER (partition BY GroupID),
                                COUNT(*) OVER(PARTITION BY GroupID) AS rowspan,
                                CASE WHEN lag(GroupID) OVER(ORDER BY groupid,accountid) = GroupID THEN 1 ELSE 0 END AS skipTd
                        FROM    #list ll
                        ORDER BY GroupID, accountid
                        FOR XML PATH('row'), TYPE, ROOT('root')).query('
{for $row in /root/row let $pos := count(root/row[. 0) then else if ($row/rowspan > 1) then else }
No. Group ID Account ID Country Account Transaction Sum Total Transaction Sum
{$pos} {data($row/AccountID)} {data($row/Country)} {data($row/AccountTransactionSum)}
{$pos} {data($row/GroupID)} {data($row/AccountID)} {data($row/Country)} {data($row/AccountTransactionSum)} {data($row/TotalTransactionSum)}
{$pos} {data($row/GroupID)} {data($row/AccountID)} {data($row/Country)} {data($row/AccountTransactionSum)} {data($row/TotalTransactionSum)}
')); SELECT @xmlBody

基本上我创建了两列，rowspan 和skipTd。第一个控制是否应适用 rowspan，第二个表示是否应跳过当前 ，因为它属于同一组。

然后我向 xquery 添加了一个嵌套的 if ，因此它根据这两个标志返回 rowspanned、“跳过”或正常 HTML。也许有更好的方法，我不是专家。
