首先是长度问题,为什么长度一大就解密失败,来看看@real_decrypt_01的定义并进行初始化@real_decrypt_01的语句: DECLARE @real_decrypt_01 nvarchar(max) SET @real_decrypt_01 = replicate(N'A', (datalength(@real_01) /2 )) 1. 2. 3. 乍一看没什么问题,但我

SET @real_decrypt_01 = replicate(CONVERT(NVARCHAR(MAX), N'A'), (datalength(@real_01) /2 )) 其它的几还有几处也是该原因,改正后进行重新运行,问题解决,长度较大的存储过程也解密成功。 第一个问题解决了,如何能方便的输出呢,试验了删除重建,但未成功,那么就用最简单的方法吧,利用xp_cmdshell将内容输...

protector for a server means to switch to a new asymmetric key that protects the databases on the server. Key rotation is an online operation and should only take a few seconds to complete. The operation only decrypts and re-encrypts the database encryption key, not the entire database. ...
