【中文标题】如何将排序规则更改为数据库的所有列？【英文标题】：how to change the collate to all the columns of the database? 【发布时间】：2013-05-19 18:26:29 【问题描述】：我想更改我数据库中所有表的所有列的排序规则。在堆栈溢出中，我找到了这个脚本：(post)
SELECT 'ALTER TABLE [' + SYSOBJECTS.Name + '] ALTER COLUMN [' + SYSCOLUMNS.Name + '] ' +
SYSTYPES.name +
CASE systypes.NAME
WHEN 'text' THEN ' '
ELSE
'(' + RTRIM(CASE SYSCOLUMNS.length
WHEN -1 THEN 'MAX'
ELSE CONVERT(CHAR,SYSCOLUMNS.length)
END) + ') '
END
+ ' ' + ' COLLATE Latin1_General__CI_AI ' + CASE ISNULLABLE WHEN 0 THEN 'NOT NULL' ELSE 'NULL' END
FROM SYSCOLUMNS , SYSOBJECTS , SYSTYPES
WHERE SYSCOLUMNS.ID = SYSOBJECTS.ID
AND SYSOBJECTS.TYPE = 'U'
AND SYSTYPES.Xtype = SYSCOLUMNS.xtype
AND SYSCOLUMNS.COLLATION IS NOT NULL
AND NOT ( sysobjects.NAME LIKE 'sys%' )
AND NOT ( SYSTYPES.name LIKE 'sys%' )
GO
但是，当我看到列的排序规则时，我发现排序规则是旧的排序规则。
实际的排序规则是 AS，所以我可以有“ANIMAL”和“ÁNIMAL”。当我执行脚本时，我没有收到任何错误。我认为我会得到一个错误，因为新的排序规则是 AI。所以这让我觉得脚本什么都不做。
如何更改数据库中所有表的所有列的排序规则？
谢谢。
【问题讨论】：
当数据库已经建立时，答案略有不同。 ***.com/questions/21149470/… 【参考方案1】：试试这个 -
查询：
DECLARE @collate SYSNAME
SELECT @collate = 'Cyrillic_General_CS_AS'
SELECT
'[' + SCHEMA_NAME(o.[schema_id]) + '].[' + o.name + '] -> ' + c.name
, 'ALTER TABLE [' + SCHEMA_NAME(o.[schema_id]) + '].[' + o.name + ']
ALTER COLUMN [' + c.name + '] ' +
UPPER(t.name) +
CASE WHEN t.name NOT IN ('ntext', 'text')
THEN '(' +
CASE
WHEN t.name IN ('nchar', 'nvarchar') AND c.max_length != -1
THEN CAST(c.max_length / 2 AS VARCHAR(10))
WHEN t.name IN ('char', 'varchar') AND c.max_length != -1
THEN CAST(c.max_length AS VARCHAR(10))
WHEN t.name IN ('nchar', 'nvarchar', 'char', 'varchar') AND c.max_length = -1
THEN 'MAX'
ELSE CAST(c.max_length AS VARCHAR(10))
END + ')'
ELSE ''
END + ' COLLATE ' + @collate +
CASE WHEN c.is_nullable = 1
THEN ' NULL'
ELSE ' NOT NULL'
END
FROM sys.columns c
JOIN sys.objects o ON c.[object_id] = o.[object_id]
JOIN sys.types t ON c.system_type_id = t.system_type_id AND c.user_type_id = t.user_type_id
WHERE t.name IN ('char', 'varchar', 'text', 'nvarchar', 'ntext', 'nchar')
AND c.collation_name != @collate
AND o.[type] = 'U'
输出：
-------------------------------------------------- ------------------------------------------------------------------------------------------------------------------

【讨论】：
我尝试使用该脚本，它似乎可以工作，但什么也没做。然后我尝试使用alter table，我看到发生错误，因为该字段在索引中使用。所以我认为该脚本不会更改任何表，因为它发生了一个或多个错误。 @Álvaro García，这个脚本很实用，我用了好几次。这个想法是你指定你的 COLLATE，复制生成的 ALTER 结构，然后执行它们。没有通用的解决方案可以毫无问题地更改列整理。此类问题总是涉及更改数据库中的排序规则，例如，如果字段是外键。 输出中的命令有一个警告。您缺少文本数据类型的 CASE 语句。以文本为数据类型的列没有应用长度。所以 text(100) 将是无效的。 这个答案绝对有效，因为我已经使用过它。感谢您的脚本，它为我节省了很多时间。 如果列有索引约束或复合键约束怎么办。是否可以将这些条件添加到此查询中【参考方案2】：我从各种不同的来源收集了下面的脚本，这些来源删除了依赖项，更新了排序规则，然后重新创建了依赖对象。这解决了更新具有依赖关系（索引、外键约束等）的列的排序规则的问题

* This script will check individual columns collations and check it against the

* required to drop all the objects dependant on the column, change the collation

* Some of the code has been reused from stuff found online the majority from

* Minor edit by Darren S to support SQL2019: Replaced AND ty.name !='sysname' with AND (ty.Name LIKE '%char%' OR ty.Name LIKE '%text%')

你先生，是MVP！ 这应该是最佳答案 我遇到了一些问题，因为查询试图更改非文本列的排序规则，所以我添加了一个 `AND c.collation_name IS NOT NULL` 和WHERE 的结尾第一个光标的分句，它工作正常。
我无法用言语来解释我多么感谢你！。
脚本很酷，但错误很少： * 计算列未处理， * 文本类型处理错误，文本列添加大小但文本没有大小【参考方案3】：
我正在发布对上述答案的编辑，其中涉及 char 和 varchar 长度，因为我之前的编辑看起来被拒绝了。

【参考方案4】：感谢大家的建议，在将我的数据库从 SQL Server 2008 R2 迁移到 2014 时，它对我有很大帮助
注意：某些结果查询的 VARCHAR(-) 无效，我将其更改为 VARCHAR(MAX)，它工作正常。
更改排序规则的步骤：
-
运行上述查询并获取 Alter table 查询
删除表和表值函数的所有索引
运行第 1 步生成的查询
创建表和表值函数的索引。
【讨论】：
【参考方案5】：虽然其他方法都不适合我，但this article by Douglas P. Castilho 为我提供了完整的解决方案。我分享它以防它帮助任何人。
-
为所有数据库创建备份。
停止服务器上的 SQL Server 服务。
打开命令提示符并导航到 Binn 目录，如
C:\Program Files\Microsoft SQL Server\MSSQL11.MSSQLSERVER\MSSQL\Binn
-
执行以下命令以应用新的排序规则。
sqlservr -m -T4022 -T3659 -q"[输入排序规则名称]"
-
再次启动 SQL Server 服务。
就是这样。

【参考方案7】：对于正在使用 phpMyAdmin 寻找此解决方案的任何人，“数据库操作”选项卡底部有一个选项（先单击数据库，然后单击顶部工具栏上的“操作”选项卡）；向下滚动到排序规则框，选择排序规则，选中两个复选框（选中第一个复选框时出现一个）：
更改所有表排序规则 更改所有表列排序规则似乎基本上运行像发布的脚本一样；控制台显示执行的最终命令：
ALTER TABLE `DB_NAME`.`LAST_TABLE_IN_DB`DEFAULT CHARSET=utf8mb4 COLLATE utf8mb4_unicode_ci
【讨论】：
【参考方案8】：也许更简单的方法是使用 PowerShell 和 SMO，例如：
$db = Get-DbaDatabase -SqlInstance MyServer -Database MyDb
$db.Tables | %
$t = $_
$t | %
If ($_.Collation -eq 'SQL_Latin1_General_CP1_CI_AS')
$_.Collation = 'Latin1_General_CI_AS'
