口音和不区分大小写的COLLATE在Oracle中等效

问题描述

在Microsoft SQL Server中，如果我想在区分大小写的数据库中不区分大小写地搜索，则可以运行以下SQL:

In Microsoft SQL Server, if I want to search case insensitively in a case-sensitive database, I can run the following SQL:

SELECT * FROM MyTable
WHERE MyField = 'BobDillon' COLLATE Latin1_General_CI_AI

这将找到所有"bobdillon"条目.

And that will find all "bobdillon" entries.

如果我想在Oracle中做同样的事情，我知道我可以这样做:

If I want to do the same in Oracle, I know I can do this:

SELECT * FROM MyTable
WHERE UPPER(MyField) = 'BOBDILLON'

但是我想知道是否有与collat​​e关键字直接等效的内容，因此我可以根据需要搜索区分大小写和重音符号.

But I want to know if there is a direct equivalent to the collate keyword, so I can search for case sensitivity and accent sensitivity as I see fit.

推荐答案

SELECT *
FROM MyTable
WHERE NLSSORT(MyField, 'NLS_SORT = Latin_CI') = NLSSORT('BobDillon', 'NLS_SORT = Latin_CI')
