运行此脚本时出现以下错误。我尝试过使用以下内容: 收集Latin1_General_CI_AS。请问它可以分类吗?感谢

似乎您的数据库中有不同的排序规则类型。然后,在连接表或其他数据库中的表时可能会出现问题,如本例所示。要解决此问题,您可以在连接两列时使用COLLATE子句指定列的排序规则或强制排序规则。查看more info about collation in MSDN
此外,您还需要指定使用有问题列的COLLATE子句。 Check this answer,它回答了一个非常相似的问题
最好在全球范围内坚持单一整理。否则你会遇到问题。
的详细说明已编辑:要检查列排序规则,请使用此代码段
SELECT name, collation_name
FROM sys.columns
WHERE OBJECT_ID IN (SELECT OBJECT_ID
FROM sys.objects
WHERE type = 'U'
AND name = 'your_table_name'
)
AND name = 'your_column_name'
已编辑:添加了代码段以获取数据库中具有不同排序规则的所有列
SELECT [TABLE_NAME] = OBJECT_NAME([id]),
[COLUMN_NAME] = [name],
[COLLATION_NAME] = collation
FROM syscolumns
WHERE collation <> 'your_database_collation_type'
AND collation IS NOT NULL
AND OBJECTPROPERTY([id], N'IsUserTable')=1

试试这个
ace.EmailAddress COLLATE Latin1_General_CI_AS = u.EmailAddress COLLATE Latin1_General_CI_AS
