Question

如何在 mysql 中区分大小写，除了字符串的第一个字符？

示例:

字符串:ABC12345

• aBC12345:好的
• abc12345:否
• ABc12345:否

Answer 1

您可以使用REGEXP :

select * from mytable where binary myfield REGEXP '^[aA]BC12345$';

记下:

The REGEXP and RLIKE operators work in byte-wise fashion, so they are not multibyte safe and may produce unexpected results with multibyte character sets. In addition, these operators compare characters by their byte values and accented characters may not compare as equal even if a given collation treats them as equal.
