TSQL&；SSRS-返回两个不同数据集的同一查询

这解释起来有点尴尬，所以我会尽力的

我在SSMS 17中编写了一个查询。查询运行良好，并正确返回1990-01-01至2018-03-04的数据。这是正确的，2018-03-04是该查询的最新案例

当将这个精确的查询放到SSRS（VisualStudio）中时，我最初放置了一个between数据参数，该参数级联到另外两个选项以选择案例类型和位置。我将这些作为单独的数据集来链接参数以级联它们。这一切都很好。只有在我对报告进行最后检查时，我才意识到我无法获得2017年10月27日之后的任何数据任何数据上都没有筛选器。

最后，我已经删除了所有参数，所以它只是主要的数据集，并加入了一个代码来提取过去两年的数据。这仍然在2017年10月27日结束。有人知道在SSMS中运行的同一查询如何正确返回数据，但复制并粘贴在SSRS中，而不是突然无法通过2017-10-27吗

当时只有1615行，所以并不是有大量的数据，我已经达到了一些极限

真的被这个难住了。我没有发布我的代码，因为它在SSMS中工作没有问题，所以我不相信问题存在

这是当前使用的代码。日期的长实例是将UTC数据库时间计数器设置为BST

第一行在SSRS中显示良好，第二行完全不可见。这项工作将完成的主要日期是[涉及的日期]的最后一个日期。

我能想到的唯一一件事是BST转换可能会以某种方式影响它，因为这是我对日期所做的唯一一件事

将此查询加载到SP中，并给出SP的源代码，我希望这将解决问题，因为代码非常庞大

您已将事务隔离级别设置为“读取未提交”
由于此隔离级别会话，同一查询可能返回两个不同的数据集。如果事务下的任何表被更新（插入、更新或删除），而未提交或回滚的同一事务未完成，则未提交的值将在“读取未提交”隔离事务会话的select查询中显示（脏读）。
因此，设置事务隔离级别快照

嗨，所有的道歉，我似乎已经想得太多了。感谢那些提出想法的人

它原来是共享数据源，我们有一个实时和测试环境。数据源说它指向live，但当我检查连接字符串时（为什么我之前没有想到它），它实际上是在查找数据有限的测试服务器

---

用这个看不见树林：）所以吸取了教训。记住检查连接字符串，而不仅仅是名称

请发布一些示例代码、模式和数据。它可能与由设置选项、空处理等引起的无提示错误有关。在SSMS中运行代码可能会给其他客户端带来不同的结果，例如ARITHABORT@gbn添加了代码，但它是一个很长的一个和一些样本数据来尝试帮助；1.如果从SSRS数据集查询设计器运行代码并键入参数，您会得到正确的结果还是“截断”版本？2.你确定你的SSRS数据集指向与SSMS相同的服务器/数据库，而不是某个开发或UAT服务器吗？@AlanSchofield Hi Alan，你的回答是在我在下面发表我自己的评论的同时出现的，但它指向了错误的服务器。共享数据源说这是我们的“实时”服务器，但当我检查连接字符串时，它指向测试。测试数据比我们的实时数据少，但SSMS查询直接实时。鸡蛋在我脸上！我想我想我太多了，可能出了什么问题，看不见树木了。没问题，很高兴你把问题解决了。。。我自己也做过很多次同样的事情。
