When OCTETS is used as the string length unit, the length of a string is determined by simply counting the bytes of the string.

使用 OCTETS 作为字符串长度单元时，通过简单地计算字符串的字节数即可确定字符串的长度。

The same functionality could be derived by using CHARACTER_LENGTH and using OCTETS as string length units.

使用CHARACTER_LENGTH并使用OCTETS作为字符串长度单元时也会产生同样的功能。

youdao

This function, as mentioned in SQL standard, returns the length of the input string in octets or bytes.

如 SQL 标准中所述，此函数返回输入字符串的八位字节长度或字节长度。
