什么整理的mysql区分utf8字符

Question

我想要一个区分utf8字符的字符集

我希望选择（'thanh'='thành'）返回0而不是1。

我尝试过utf8_unicode_ci，utf8_general_ci，utf8_bin，utf8_vietnamese_ci。但是所有这些都返回1以进行上述查询。

Answer 1

你需要使用CAST（...）COLLATE utf8_bin。

<强>查询

SELECT CAST('thanh' AS CHAR) COLLATE utf8_bin = CAST('thành' AS CHAR) COLLATE utf8_bin;

<强>结果

CAST('thanh' AS CHAR) COLLATE utf8_bin = CAST('thành' AS CHAR) COLLATE utf8_bin
