【问题描述】：
我创建了一个变量 SQL 查询，我在其中声明了我想要使用的 SQL 查询，因为变量表名称。我们的 SQL 是根据系统中的帐户名设置的。这意味着它看起来有点像这样：[LSRetail].[dbo].[AccountName$Item]。
这里的LSRetail 部分是动态的，因为如果它是丹麦，它被称为LSRetailDK，如果它是瑞典，它被称为LSRetailSE。 AccountName 也是动态的，因为商店名称和邮政编码不同...
所有这些实际上都有效并且被声明并设置为@Sql，但是由于空间的原因，我想做另一个DECLARE @Sql2 VARCHAR(8000)，我想在其中SELECT * FROM @Sql。由于@Sql 以with cte1 AS ( 语句开头，它不允许我这样做。
这里可以做点什么吗？我想将两者结合在@Sql2 或@Sql3 中。
现在，唯一有效的是 SET @Sql2 = @Sql 并执行它。
下面的代码是@Sql 的代码，我想在@Sql2 中使用它。
DECLARE @OrderNo VARCHAR(50);
DECLARE @StoreName VARCHAR(100);
DECLARE @Table1 VARCHAR(1000);

提前感谢您的帮助。
注意：我使用 SQL Server。
【问题讨论】：
-
为什么不粘贴示例代码和预期的输出。我认为这比您的文字容易理解。
-
@JaimeDrq 现在已添加到其中 - 这是一个很长的代码 :)
-
这感觉就像您需要修复您的设计，而不是 SQL。每个商店都有不同的桌子是你遇到问题的原因。修复设计，修复问题。
-
旁注： 像
[','' + @StoreName + '','$Sales Invoice Line]这样的代码不是注入证明。像'MyTable]; DROP TABLE dbo.MyTable];--这样的值仍然会注入。如果必须注入对象名称，请使用QUOTENAME。 切勿将未经处理的字符串注入您的动态查询中。 -
你也必须参数化你的陈述（我不能强调必须更多） .
' + @DisclaimerDiscount + '是一个非常的坏主意。评论不是告诉你如何正确编码的地方，没有巨大的安全漏洞，所以请花时间阅读我在Dos and Don'ts of Dynamic SQL写的一篇文章
