I have a list of company names and the user has to enter his company name to get into the system. Let's say we have the company "Pré ABC", now I want the user to be able to type "Pre" or "Pré".
我有一个公司名称列表,用户必须输入他的公司名称才能进入系统。假设我们有公司“PréABC”,现在我希望用户能够键入“Pre”或“Pré”。
First I thought this was build-in functionality of the LIKE statement, but unfortunately it isn't. Any thoughts?
首先我认为这是LIKE语句的内置功能,但遗憾的是它不是。有什么想法吗?

This has to do with collation. Each database has its own collation (and any column can override that collation, too). In your case, you're looking for a collation that's not accent-sensitive, and not case-sensitive. Try configuring the database to "SQL_Latin1_General_CP1_CI_AI". That decodes as "code page 1, case-insensitive, accent-insensitive", which should make your queries work as desired.
这与整理有关。每个数据库都有自己的排序规则(任何列都可以覆盖该排序规则)。在您的情况下,您正在寻找一种非重音敏感的排序规则,而不是区分大小写。尝试将数据库配置为“SQL_Latin1_General_CP1_CI_AI”。解码为“代码页1,不区分大小写,不区分重音”,这应该使您的查询按预期工作。

SELECT 1
WHERE N'Pré ABC' COLLATE LATIN1_GENERAL_CI_AI LIKE N'%Pre%'
