同一个查询，同一个数据库，不同的服务器，不同的结果

本文介绍了同一个查询，同一个数据库，不同的服务器，不同的结果的处理方法，对大家解决问题具有一定的参考价值，需要的朋友们下面随着小编来一起学习吧！ 问题描述

我们在服务器上有我们的主数据库，有这个存储过程；当我们对数据库运行它时，它返回错误的值.

We have our main database on a server, there is this stored procedure; when we run it against the database, it returns wrong values.

但是当我备份这个数据库并在另一台服务器上恢复它并运行完全相同的查询时，它返回正确的答案.

But when I take a back up of this database and restore it on another server and run the exact same query, it returns the correct answer.

我能做什么?

SQL Server 的配置是否有可能影响查询返回结果的方式?

Is it possible that the configuration of SQL Server affects how a query returns results?

如果是，我可以从哪里开始寻找问题?

If yes where can I start looking for problem ?

这是存储过程，完全相同的过程在两个数据库上运行并且两个数据库是相同的.

Here is the stored procedure, the exact same procedure runs on both databases and both databases are identical.

推荐答案

如果没有您的数据库副本(不是请求)，就不可能回答这个问题.

Without a copy of your db (not a request) it's not possible to answer this.

SQL Server 的配置是否有可能影响查询返回结果?

Is it possible that the configuration of SQL Server affects how a query returns results?

是的，这是一种可能性.例如，如果您的 ANSI两个服务器之间的 NULL 设置不同，则在 ANSI_NULL 设置为 OFF 的服务器上，NULL 将等于 NULL，但在 ANSI_NULL 为 ON 的服务器上则不然.整理 是另一个.如果一台服务器具有区分大小写的排序规则，则A"和a"不相等，而使用 SQL Server 默认值则相反.这些只是几个例子.

Yes this is a possibility. For example, if your ANSI NULL settings are different between the two servers then NULL will be equal to NULL on the server has ANSI_NULL set to on OFF but not on the server where ANSI_NULL is ON. Collation is another. If one server has a case sensitive collation the "A" and "a" are not equal whereas the opposite is true using the SQL Server default. These are just a couple examples.

也就是说，他们隔离问题的方法是将存储的过程分解为多个部分，并尝试确定差异的开始位置.在您分配变量的第一步中，添加一个步骤将它们转储到一个临时表中，您可以在两个服务器之间汇总和比较该表.如果没有差异，请继续向下运行每个部分，直到找到差异为止.通常我会将所有内容都注释掉，然后从上到下取消注释代码，直到找出问题为止.

That said, they way to isolate the problem is to break the stored proc up into parts and try to identify where the differences are starting. In the first steps, where you assign variables, add a step to dump them into a temp table that you can summarize and compare across both servers. If there's no differences keep moving down the proc running each part until you find a difference. Often I'll comment everything out then uncomment code from top-to-bottom until I isolate the problem.

最后，您在这里使用了几个游标，不需要.您可以通过使代码更加基于集合从而减少冗长来简化代码.排除故障会容易得多，并且性能会好得多.

Lastly, you are using couple cursors here and don't need to. You can simplify your code by making it more set-based and therefore less verbose. It will be much easier to troubleshoot and will perform much, much better.
