MySQL - 如何按字符串长度选择数据

问题描述

SELECT * FROM table ORDER BY string_length(column);

是否有 MySQL 函数来执行此操作(当然而不是 string_length)?

Is there a MySQL function to do this (of course instead of string_length)?

推荐答案

您正在寻找 CHAR_LENGTH() 获取字符串中的字符数.

You are looking for CHAR_LENGTH() to get the number of characters in a string.

对于多字节字符集LENGTH() 将为您提供字符串占用的字节数，而 CHAR_LENGTH() 将返回字符数.

For multi-byte charsets LENGTH() will give you the number of bytes the string occupies, while CHAR_LENGTH() will return the number of characters.
