Sql server 错误：没有与此查询的执行关联的结果行集

应作为变量存储在执行SQL任务中的查询：

SSIS中的变量定义和结果集映射：

在执行SQL任务中，我选择了结果集=单行。我也没有试过。我在执行SQL任务上设置了一个执行后断点，得到了以下结果：

==如果直接在SQL Server中执行上述查询，为什么在SSIS中得到0作为值，而在SSIS中得到1

后续任务中的优先约束如下所示：

编辑1:将此表达式更改为@RowCheck==0不会更改任何内容，因为任务在执行时仍然失败，并出现相同错误：

错误：没有与此查询的执行关联的结果行集

编辑：2：将优先级约束编辑器中的值从成功更改为失败是可行的，但我不明白任务本身为什么失败，以及为什么它会生成上述错误消息？但是，尽管继续处理包，变量RowCheck显示的值没有任何意义，因为它始终为零，而不管查询返回

编辑3：执行SQL语句的常规选项卡屏幕我也尝试了单行和上述结果集映射：

---

在执行SQL任务中，尝试将SET NOCOUNT添加到SQL的顶部，可能是行计数干扰了变量赋值，导致变量赋值不为1。是的，我这样做了，但不幸的是，这没有起到作用。我仍然总是得到一个0作为变量值。你能发布一个执行SQL任务属性的常规选项卡的屏幕截图吗？您是否也尝试过使用探查器来验证包执行的SQL是否符合预期？并返回您期望的结果？@TabAlleman我在相应选项卡的上方发布了一张图片。不知道你的意思是什么。我在哪里能找到它？我刚刚在SQLServerStudio中执行了SQL，在那里我得到了预期的结果/值。您在测试中可能错过了很多东西，这些东西只能在发生时被捕获。有时，包或包中的对象似乎被损坏，而销毁和重新创建它们是修复它们的唯一方法。
