AES_DECRYPT SELECT WHERE在不起作用

Question

我有一個加密的MySQL DB。 當我選擇一個位置時，它不返回任何值。

SELECT cast(aes_decrypt( email , 'salt') as CHAR(100)) AS email FROM表WHERE email = 'test@email.com'返回任何結果。

SELECT cast(aes_decrypt( email , 'salt') as CHAR(100)) AS email FROM table``返回結果，結果集中帶有test@email.com。

我究竟做錯了什么。

Answer 1

排序。

, 'salt') as CHAR(100)) AS email FROM表WHERE cast(aes_decrypt( SELECT cast(aes_decrypt( email , 'salt') as CHAR(100)) AS email FROM表中的電子郵件, 'salt) as CHAR(100)) = 'test@email.com' WHERE cast(aes_decrypt( email , 'salt) as CHAR(100)) = 'test@email.com'
