Return value: A byte array. To visualize the result, you need to add thehexfunction orbase64function to the original statement. For example: hex (des_encrypt (...)) or base64 (des_encrypt (...)) Example: SELECT hex(des_encrypt(`Roxy@fanraun.com`,`my8bytky`,`ECB`,`PKCS5`,null...
后来自己根据实际的应用环境,编写了两个存储过程,一个加密存储过程(sp_EncryptObject),和一个解密存储过程(sp_EncryptObject),它们可以应用于SQL Server中的储过程,函数,视图,以及触发器。 感觉这两个存储过程蛮有意思的,拿来与大家分享;如果你看过类似的,就当作重温一下也好。 用于加密的存储过程 (sp_EncryptObjec...

In-place cryptographic operations can't be combined with any other changes of column metadata, except changing a collation within the same code page and nullability. For example, you can't encrypt, re-encrypt, or decrypt a column AND change a data type of the column in a singleALTER TABLE...
利用密码短语方式：搭配EncryptBypassPhrase进行加密，使用DecryptByPassPhrase函数解密，可使用有意义的短语或其他数据行作为关键字，适合一般的数据加解密。恢复方法从备份中恢复：若有定期备份，可使用SQL Server Management Studio (SSMS) 等工具，选择“还原数据库”选项，指定备份文件位置。恢复前要了解备份...
