SQL Server Admin 2014 :: Using Column Encryption With Symmetric Keys
Jun 25, 2015I am trying to implement the column encryption on one of the tables, have used the below link as the reference and got stuck at the last step.
[URL] ....
I have completed the following steps so far.
- CREATE MASTER KEY ENCRYPTION BY PASSWORD = ‘myStrongPassword’
- CREATE CERTIFICATE MyCertificateName
WITH SUBJECT = 'A label for this certificate'
- CREATE SYMMETRIC KEY MySymmetricKeyName WITH
IDENTITY_VALUE = 'a fairly secure name',
ALGORITHM = AES_256,
[Code] .....
Example by using the function
EXEC OpenKeys
-- Encrypting
SELECT Encrypt(myColumn) FROM myTable
-- Decrypting
SELECT Decrypt(myColumn) FROM myTable
When I ran the last command :
-- Decrypting
SELECT Decrypt(myColumn) FROM myTable
I get the following error :
Msg 257, Level 16, State 3, Line 2
Implicit conversion from data type nvarchar to varbinary is not allowed. Use the CONVERT function to run this query.
Where will I use the convert function, in decrypt function or in select statement?

SQL Server Admin 2014 :: Disabling Database Encryption - During Or After Production Hours?

Jul 16, 2015How you are handling the replication of the many instance-level objects/items (logins, linked servers, server roles, database mail, operators, on and on) to the replicas in an AlwaysOn topology.
I'm especially curious about DBAs managing larger SQL Server environments. In my current environment, we have approximately 80 production SQL instances containing about 650 databases that require high availability and disaster recovery.
We use mirroring today and have a solid, home-grown solution for replicating the instance-level items from production to disaster recovery. AlwaysOn changes things a bit since we'll have multiple replicas and of course the database could be active on any one of those at any time. So my concern is about instance-level items being created in one instance but never deployed to the other instances participating in the AG group.

SQL Server Admin 2014 :: Audit All Server DDL Level Events?
Mar 6, 2015I have been tasked with auditing all DDL and selected DML events on a production server and logging them to a table. My solution is to use CDC for the DML and a Server-Level trigger for the DDL. Because there should never but much DDL activity on the server (except when performing update tasks) I don't need to worry about the trigger consuming too many resources.
My question is this: Is there any single specification such as DDL_LEVEL_EVENTS that can capture all DDL activity or do I need to specify each and every DDL action in the trigger?

SQL Server Admin 2014 :: Restoring A Database Even If No Database Or Backup Encryption
Sep 3, 2014I did tried the encryption on server "A" for database "AdventureWorks2012". Then I tried to restore to server "B". There was the certificate issue, and I thought "of course : it's encrypted ! Let's deactivate it". So here I go "ALTER DATABASE AdventureWorks2012 SET ENCYRPTION OFF".I look at sys.databases : not encrypted.I backup using no encryption, I verify using msdb.dbo.backupset : not encrypted.
I move my backup to my other server where encryption was never configured (so no certificate, nothing...), and I have the error :
Msg 33111, Level 16, State 3, Line 1
Cannot find server certificate with thumbprint '0xFA130E58C999C4919B8975999C83A75A403B11D8'.

SQL Server Admin 2014 :: Change Data Capture(CDC) For Data Warehouse / Reporting?
Aug 12, 2015I have a requirement to implement CDC for 50+ tables to implement incremental data changes warehouse/reporting rather than exporting the whole table data. The largest table is having more than half a billion records.
The warehouse use a daily copy of OLTP db (daily DB refresh). How can I accomplish this. Is there a downside in implementing CDC just for the sake of taking incremental changes on the tables?
Is there any performance impact if we enable CDC on OLTP db?
Can we make use of the CDC tables on the environment we do daily db refresh so that the queries don't hit OLTP database?
What is the best way to implement CDC to take incremental changes for reporting.

It blocked and caused a huge mess, I suspect on the removal part. But I want to confirm that the emptyfile completed (and that the engine isn't going to try to put more data in there for when I schedule the removal part again a week or more from now).
How does the engine know not to put any more data in there, and how long does that situation last?
