如何查找具有包含小写字母的值的行 [英] How to find rows that have a value that contains a lowercase letter

问题描述

我正在寻找一个SQL查询，该查询将为我提供ColumnX包含任何小写字母(例如"1234aaaa5789")的所有行.大写字母也一样.

I'm looking for an SQL query that gives me all rows where ColumnX contains any lowercase letter (e.g. "1234aaaa5789"). Same for uppercase.

推荐答案

SELECT * FROM my_table 
WHERE UPPER(some_field) != some_field

这应该适用于åäöøüææï等有趣的人物.您可能需要为表使用特定于语言的utf-8归类.

This should work with funny characters like åäöøüæï. You might need to use a language-specific utf-8 collation for the table.
