I'm having problems with the following code:
--DROP MASTER KEY
--GO
USE master;
CREATE MASTER KEY
ENCRYPTION BY PASSWORD = 'Pass@word1';
GO
USE master;

What am I missing? What do I have to do if I get in a situation where I need to back out and start over?

I need to encrypt some column level data in multiple tables in SQL server 2014. I've never tried encryption in SQL server 2014. How can I achieve it?
View 4 Replies View RelatedI inherited a lot of Servers to upgrade to 2014 to include an SSRS Server.
The encryption Key was never backed up and it seems that no one knows what the password is?
Do I have to manually load the reports? There are a lot of Reports.

I 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?
I have to disable newly implemented database encryption. It's a necessity unfortunately. Can I do this during production hours without much of a hit? I know I have to restart the instance after it's done. Can I expect performance impacts or other issues?

Running SQL Server 2008 R2 Enterprise.
I try to load data into a memOpt table (INSERT INTO ... SELECT ... FROM ...). The source table has a size about 1 Gb and 13 Mio Rows. During this load the LDF File grows to size of 350 GB (until the space if the disk is run out of space). The Server has about 110 GB Memory for the SQL Server reserved. The tempdB doesn't grow. The Bucket Size in the create statement has a size of 262144. The Hash key as 4 fields`(2 fields have the datatype int,1 has smallint, 1 has varchar(200). ) The disk for the datafiles has still space for the datafiles (incl. the hekaton files).
How can I reduce the size of the ldf files during the load of the data ?
I 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'.

View 3 Replies View RelatedI 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.

View 3 Replies View RelatedI'm being asked to create multiple filegroups for a new database based on the table type, transaction, lookup, misc... From what i'm reading this doesn't make sense. I'm reading either large tables get file groups, nonclustered indexes when they are about the same size of the data, or a few other reasons...
First of all, we are talking about the same disk (please don't ask me about how it is configured) and I'm not sure yet if restoring separate file groups is even going to be necessary.
So here are my questions (beyond, the test and see what happens) because in the end I'm going to probably have to do what i'm told. So this is for my professional knowledge.
1. Does file groups separated by table type make sense?
2. Should you put tables that are queried often together in the same or different file groups.
3. I'm pretty sure you can't restore single file group for write access, am I correct?
And have chosen the destination - unstructered (flat) file. But the wizard proposes to export only one table (dbo.Acocount) and all the others from the list are not exported. How can I export ALL the data into one file.I need to do this to edit the syntax in the editor and then import this data and database structure into Postgresql

View 8 Replies View RelatedDoes Replication use linked server.
If not then how data will transfer from source to destination.
Note : As per my knowledge it is not backup and restore like logshipping.
If data is modified (by an insert, update, or delete) while the backup is running, will the backup contain those changes or will it be added to the database afterwards?

what is the meaning for data leakage ?
I was running an operation to shrink file/emptyfile a data file, and then remove it.
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?
