Question

我是一名IT顾问，通常管理硬件和网络，但我们的程序员目前正在休假。我对在我们15个站点的练习管理软件服务器上的两个数据库上运行的MSSQL查询进行了一些修改，并且我在与整理相关的一些服务器上收到错误冲突。

在我们大多数网站的服务器上运行良好，但是出现了15台服务器中有4台服务器出于某种原因使用不同的排序规则。

我已经考虑过尝试更改整理，但它并没有顺利进行，所以我希望也许我可以调整查询，因此对于这些服务器而言，整理的差异并不重要。事实上，如果查询是“排序规则不可知”，那就更好了。这样我就可以在所有服务器上使用相同的查询而无需关心整理......可以这样做吗？

确切的错误是

Msg 446，Level 16，State 11，Line 1   无法解决＆＃34; Latin1_General_CI_AS＆＃34;之间的整理冲突和＆＃34; SQL_Latin1_General_CP1_CI_AS＆＃34;在CASE运算符中进行DISTINCT操作。

Msg 446，Level 16，State 11，Line 1   无法解决＆＃34; Latin1_General_CI_AS＆＃34;之间的整理冲突和＆＃34; SQL_Latin1_General_CP1_CI_AS＆＃34;在CASE运算符中进行DISTINCT操作。

我正在运行的查询是：

SELECT DISTINCT
-- setup columns
[cases].[reference] as MatterNumber,
[dd_entity_d2].[type] as ClientType,
[dd_client].[clientname] as MatterName,
CASE WHEN [dd_entity_d2].[type] ='Individual' THEN etClient.FirstName ELSE [dd_entity_d4].[firstname] END AS FirstName,
CASE WHEN [dd_entity_d2].[type] ='Individual' THEN etClient.LastName   ELSE [dd_entity_d4].[lastname] END AS LastName,

    -- AND DATEPART(m, mt.CreatedOn) = DATEPART(m, DATEADD(m, -1, getdate()))
    -- AND DATEPART(yyyy, mt.CreatedOn) = DATEPART(yyyy, DATEADD(m, -1, getdate()))

    -- AND mt.[status] = 0
-- end filters 
-- setup sort
ORDER BY Email ASC
-- end sort and query

PracticeEvolve_c1是 SQL_Latin1_General_CP1_CI_AS ，而PracticeEvolve_doc是 Latin1_General_CI_AS 。

我不在这里，非常感谢您提供的任何帮助。

编辑： FWIW - 这是我在尝试更改数据库排序规则时遇到的错误：

对象＆＃39; MonthToDays365＆＃39;依赖于数据库整理。如果架构绑定对象依赖于它，则无法更改数据库排序规则。删除数据库排序规则的依赖关系，然后重试该操作

Answer 1

只需修改CASE表达式并包含COLLATE命令

即可

CASE WHEN [dd_entity_d2].[type] COLLATE SQL_Latin1_General_CP1_CI_AS 
          ='Individual' 
THEN etClient.FirstName COLLATE SQL_Latin1_General_CP1_CI_AS 
ELSE [dd_entity_d4].[firstname] COLLATE SQL_Latin1_General_CP1_CI_AS 
END AS FirstName,

由于排序规则不匹配导致对两个数据库的查询出错
