如果只找到一条记录，或者两者都被添加，则确保不添加逗号
考虑一下SQL查询的后续部分，该查询旨在以XML的形式构造复杂的返回：
ISNULL(Logbook1 + ',', '') + ISNULL(Logbook2 + ',', '') + ISNULL(Logbook3 + ',', '') AS '@logBookNums',
本质上，这将搜索相应的记录。如果发现LogBook1，LogBook2或LogBook3没有记录，则会返回空字符串。如果它在LogBook1中找到一条记录，它将返回该记录和一个尾随逗号。
不幸的是，发送此XML的WCF服务令人震惊地记录在案（实际上没有读过任何内容），它拒绝使用尾随逗号的单个日志编号。
我的猜测是它应该提交为：
logBookNums="12345,,"
或者
logBookNums="12345"
如何更改上面的SQL行以输出一个或另一个，并且（如果查询找到两个日志编号）生成如下输出：
logBookNums="12345,12346,"
或者
logBookNums="12345,12346"
这是整个查询，我需要插入一个解决方案来处理@logBookNums和@landingDecNums的困境。

当有logBookNums时，我们将获得正确格式化的xml，如下所示。
然而，当我们没有得到logBookNums =＆＃34;＆＃34;但是你看，我们一无所获。

那么你可以在Case When结构中写它，它不是那么久：
CASE WHEN Logbook1 is not null
THEN
CASE WHEN Logbook2 is not null
THEN
CASE WHEN Logbook2 is not null
THEN Logbook1+','+Logbook2+','+Logbook3
ELSE Logbook1+','+Logbook2
ELSE
CASE WHEN Logbook3 is not null
THEN Logbook1+','+Logbook3
ELSE Logbook1
ELSE CASE WHEN ...
