SQL Server 存储过程错误 - 子查询返回多个值

Question

我必须编写一个存储过程来填充收入。要求是我有两个部分，患者和配偶/其他，其中患者收入必须填写在他的部分下，而配偶/其他部分应该在该部分下。

当配偶/其他部分的成员超过一个时，我遇到了问题！下面是我的代码。

错误信息表明----

"@OtherMSN" "子查询返回超过 1 个值。这不是 当子查询跟随 =、!=、、>= 或当 子查询用作表达式。”

非常感谢任何帮助。

Answer 1

这部分查询返回了不止一行：

(SELECT MSN FROM EXT_KSR_APP_MEMBERS (nolock) WHERE APP_ID = @app_id and msn <> @msn)

因此，您的变量 @OtherMSN 有多个可能的值。您需要修复查询以返回单个行/列（标量）值，在本例中为 varchar(3)
