Greetings. I can find complete articles on how to move a DB w TDE to a new instance, but nothing on how to move a DB w column level encryption. I see different people w different issues and answers, but nothing complete.
Looking in this DB, it has both a Certificate and Symmetric Key, but if there's passwords associated w them I have no idea what they are.
So, where do I start?
Thanks in advance! ChrisRDBA
Folks,
SQL Edition : SQL2016 STD
Windows Edition: Windows 2016 STD
Standalone VM
Current allocation : 12 vCPUs (4 cores * 3 sockets)
Planning for 20vcPUs the server team requesting to know how much can SQL support , my take was 4 cores *4 sockets =16vcPUs is the max as SQL Server 2016 Standard Edition will only use four sockets because of the socket license limit.
To make use of all the 20vcPUs is 4 cores*4 sockets the best that can be done or do we have any other way to achieve the best ,Yes they will be doing the changes on VM Configuration manager
Regards and Wishes

I am searching for a document which can provide information about the best practices for schema creation on database.
Kindly provide if any document is available or suggest which is the better way to maintain schema in azure sql db/Sql stand alone. Is it to good to have same schema name in dev, test, Uat and prod or create different schema name in each environment.
Kindly assist.
I have a file inside the SFTP folder which can be downloaded into the local machine. Is there any way, I can setup a SQL server agent job to pick that csv file and upload into the SQL sever automatically and periodically?.
FYI, picking up directly from the SFTP folder is much preferred option but even picking up from the local machine also works.
Hi i have a dead lock issue when i try to insert policy purchase details to database. We collect details like vehicle information , driver information and coverage information during quote and when customer click purchase button, we insert the details in to many tables close to 75 easily where it starts with parent and child tables goes underneath. During load testing we identified that it throws dead lock issues because i have begin transaction at the start of the sql statement. If i remove begin transaction statements then it works fine without any issues, but i cannot remove begin tran because if there is any failure i want to roll back all the child tables.
Create Procedure dbo.PurchasePolicy(
@user VARCHAR(256),
@auto_policy NVARCHAR(MAX),
@transaction_date DATETIME
)
AS
EXEC sp_xml_preparedocument @doc OUTPUT, @auto_policy
SET @transaction_date = GETDATE()
Begin transaction
-- create policy
EXEC @return = dbo.PurchasePolicy @user, @doc, @transaction_date, @policy_id OUTPUT, @inception_date OUTPUT, @transaction_id OUTPUT, @process_id OUTPUT, @transaction_detail_id OUTPUT
EXEC sp_xml_removedocument @doc
-- check for error
IF (@return<>0)
BEGIN
ROLLBACK TRANSACTION PurchasePolicy
print 'error occured - transaction rolled back'
END
ELSE
BEGIN
COMMIT TRANSACTION PurchasePolicy
-- return response string
SELECT '<messages><message entity="policy_id" status="success" state_cd="' + @state_cd + '" rate_plan="' + CAST(@rate_plan AS VARCHAR) + '" inception_date="' + CONVERT(VARCHAR(20),
@inception_date, 126) + '" policy_rejected_cd="' +
CAST(@POLICY_IS_REJECTED AS VARCHAR) + '">' + ISNULL(CONVERT(VARCHAR(12),@policy_id),'') + '</message></messages>' AS message_xml,
@policy_id AS policy_id,
@POLICY_IS_REJECTED AS policy_rejected_code
END
The dead lock log has the following details
<resource-list>
<keylock hobtid="72057658262224896" dbid="9" objectname="Policy_Management.dbo.Policy_Process" indexname="PK_Policy_Process" id="lock739390d500" mode="X" associatedObjectId="72057658262224896">

I have the row lock for the following table policy_process but i dont have any update statement for the table policy
UPDATE dbo.policy_process WITH (ROWLOCK)
SET process_status_id = @PROCESS_STATUS_CLOSED,
modified_date = @rejected_transaction_date,
modified_user = @user,
close_date = @rejected_transaction_date
WHERE policy_id = @policy_id
AND process_type_id = @ACCEPTANCE
The following are the questions i have in my mind.
1. Does insert statement causes table lock when we have begin transaction, so that other process has to wait.
hi folks, we have encountered a performance hiccup a few days ago and I've noticed that one insertion to log table was called many times during that troubled period and also noticed that PLE was low as well. The symptom was the user complaining for system performance. Once the insertion process has been stopped, server has been rebooted . After that, PLE gets dramatic increase. I am not sure which task did the trick? was the table insertion being called of or the server rebooting?
Thanks

Hi,
I have virtual environment with Windows Server 2016 with MS SQL std. license with 16-core.
I need to create a cluster (Active-Passive) for two nodes. Can I create a cluster with 16-core (Each) with Std. SQL server license or 8-core each. Kindly suggest, is it possible with licensing I have mentioned above or do I need some additional licenses.

I saw in the following link
that there is one "improvement"
Simple Containment becomes Base Containment: Users might query for data that does not exist. For example, for an equality join between two tables, we use the base tables histograms to estimate the join selectivity, and then factor in the predicates selectivity.
so which means :
Select * from table1 a inner join table2 b on a.col1=b.col2 where a.col2='somevalues'
and will look for rows on the join column first ? and then col2 of the predicate where?
I just wondering what are the differences of the following event capture ? Will it affect the actual performance when the xevent session capturing the following events?

HI Experts,
Earlier we have a linked servers in our environment configured with SQL logins, due to security issues we have changed to Windows accounts and we have done delegation of computers and svc accounts as well to make it work.
test connection is also working fine but intermittent we are getting error
Login failed for user 'NT AUTHORITY\ANONYMOUS LOGON'. Reason: Could not find a login matching the name provided.
Could you please suggest for the same.
Thanks

Hi I just wanna asked why we are encountering this error ? It is only the error we see before the failover .
Stating" Cluster resource ""of type SQL Server Availability Group in cluster role “”
We have SQL server 2016 standard edition cluster setup. Active active cluster setup.
We ran into some disk errors on node two DBS02. We had replaced the failed disk and upgraded the firmware.
After upgrade and disk replacement we were not able to failover the first Instance that is SQL01 to node DBS02
The instance SQL01 is running smoothly on DBS01 (i.e node 01)
Below error is logged in SQL logs
SQL Server detected 4 sockets with 10 cores per socket and 20 logical processors per socket, 80 total logical processors; using 48 logical processors based on SQL Server licensing. This is an informational message; no

Hello,
I have a database server which is causing lot of resource demand on the storage and causing hypervisor to lock up.
How should I troubleshoot this? Please advise
