Server Alias
May 13, 2004
how to add a alias to a server?
I have gone through BOL where it says it can be done thru right click agent -->> connections and configure alias.
i want to know if i configure a alias to a server from a client is it valid for other connections also?
meaning there are two database servers A and B
i add alias to server A by using client network utilities on server B,
then is this alias available if i try to connect to the server A thro some other server c?
hope this is not that confusing as it sounds. ;)

We will be moving 2 different databases (SS2005 & SS2008) to a new SS2014 SQL Server.  Currently our codes looks something like Server1DBInstance1... & Server2DBInstance2... Is it possible to move the objects from these 2 instances to Server3DBInstance3 and then use an alias to reference the objects?  Or does Server3 need to have DBInstance1 & DBIstance2?  Basically, is the alias just for the database or for the instance too?  Can I create an alias "Server1DBInstance1' on Server3DBInstance3 and assign objects to that alias?

Is there any way to refer to an Alias in a select statement? For example, if I create an expression that sums to fields together and give it the alias TOTAL, and then in another field I want to create and other expresssion that multiplies a field by TOTAL, what is the syntax?
In MS Access the Alias name is surrounded by brackets, but I can't seem to find a way to do this with SQL Server.
Thanks

We have a SQL 2000 installation on a server called SATURN that has been around for a while. We've installed a new SQL 2005 installation on a server called DEIMOS. Our intention is to move all the databases that are currently on SATURN, to DEIMOS.
I've just been looking at the config settings, and it's suddenly occurred to me that the ability to set Server Aliases might save me quite a bit of work. What I'm thinking is setting a new alias on DEIMOS called SATURN. Then I won't need to go round the various applications changing the connection properties.
So:
Does this sound reasonable?
I intend uninstalling SQL 2000 from SATURN, but the server itself will stay - is that ok?
What will happen if SQL comes alive on the server SATURN while the alias is in place - effectively there will be 2 servers responding to SATURN. I ask this because my intention is to shut down all the SQL services on SATURN, set up the alias, and once I'm happy with the testing, then uninstall. Just wondering what will happen if for some reason the services were restarted before I finish.
Is there anything else I need to consider?Regards,
Tim

Today I found a problem with alias name during retrieving values from database table with alias name. My query was like as following:
========================================================SelectEmpID,Case EmpNameOrEmpFirstLastNameWhen ‘EN’ ThenEmpNameElse--EmpLast + “, � + EmpFirst
EmpLast + ', ' + EmpFirstEnd As EmpName,CityFrom tblEmployeeWhere EmpName LIKE ‘N%’=======================================================
When I execute this query I get all the record which contains the N% in EmpName as well as from FirstName. As you know that should not because I give alias name EmpName to EmpLast + ', ' + EmpFirst. But here the problem is we cannot use the alias name in Where condition.
I resolve this problem by using #temp table like the following:=======================================================SelectEmpID,Case EmpNameOrEmpFirstLastNameWhen ‘EN’ ThenEmpNameElse--EmpLast + “, � + EmpFirst
EmpLast + ', ' + EmpFirstEnd As EmpName,CityInto #tmpEmployeeFrom tblEmployee
Select * from #tmpEmployee where EmpName LIKE ‘N%’=======================================================
It really very simple, isn’t it? You can use the reference link:Reference: http://www.thescripts.com/forum/thread82710.html
So friends enjoy, we are the Sql Master:)Regards,Vijay Modi

I have a SQL Server 6.5 db on a server, we need to migrate SQL Server to another server.
We have about 400 users connected to an OBCD driver pointing to the original server and
would like to connect them to the new server.
How can I do this without changing all the users OBCD settings?
Is there a function to alias the new server?

I understand there is a way for a user to connect to a SQL Server
using an ALIAS ( i.e. I am connected with one instance using the
name DUBAY and now I want to make another connection with my
ALias - George). I'd appreciate anyone telling me how to do this.
Thanks in advance.

I am moving my Sql Server installation to a larger machine. In doing so, I don't want to change everyone's connection settings. Does anyone see any issues with using an DNS alias to connect to the new server?
Using the same name is not an option per the windows admin group that is provisioning the machine.
Thanks,
Andy

Hi,
In DTS 2000 when you created a connection you could use a server alias (as created in the network client utility) as the servername. When I try to use a server alias in connection mgr(I am using Native Client) it fails to connect with the standard error: "Test connection failed because of an error in initializing provider. Login timeout expired. etc etc...
Has anyone had success using a server alias? (Yes i set up the alias using sql configuration mgr)
The problem I am trying to solve is I have dev/test/production environments that I want to move this package to and I don't want to have to change any server name properties within the package when moving to the different environments.
Thanks

I had two servers, in which SQL Servers are installed. I created a alias for server
Server 1 : test1.sqlcloud.com (Alias name with port no other than 1433)
Server 2 : test2.sqlcloud.com (Alias name with port no other than 1433)
I can connect to the servers using the port. for ex server1 to server2 and viceversa using "test2.sqlcloud.com,port". But I could not connect to the server by only specifying the alias name ("test2.sqlcloud.com"). When I am connecting I am getting the following error.
"TITLE: Connect to Server
------------------------------
Cannot connect to test2.sqlcloud.com.
------------------------------
ADDITIONAL INFORMATION:
Connection Timeout Expired. The timeout period elapsed while attempting to consume the pre-login handshake acknowledgement. This could be because the pre-login handshake failed or the server was unable to respond back in time. The duration spent while attempting to connect to this server was - [Pre-Login] initialization=21020; handshake=0; (Microsoft SQL Server, Error: -2)

so you have two place to configure alias, in SQL server configuration manager under aliases tab on and on the cliconfg.exe tool on a different machine. If I want another server to see this sql server by the alias name I will need to configure the alias on the cliconfg tool on the client machine. It looks like as long as I have the alias configured in the cliconfg on the client machine, I don't need the alias to exist on the config manager, the client can still see SQLserver using just the alias on cliconfg...if so, I wondering under what situation I would really need the alias on the configuration manager?

Hello,
I would like create/modify/update the alias SQL server name on the SQL 2005 version.
I had a database mirroring on one base, and when the primary server fail, i would like my secondary alias become as the primary. I need this because of the application whom use my SQL server.
I tried with
sp_dropserver <old_name>
GO
sp_addserver <new_name>, local
GO
But this way doesn't work...
Anyone got an idea to change alias SQL server in transact?
Thanks for your help!!!

Can someone please shed some light on what seems to me to be a common requirement.
If I create an alias or linked server to Server1 - say Alias1 - on Server1 and then use that name in a query on Server1, a remote/distributed query is always used (even though we are running on the local server and that overhead is completely unnecessary).
Is SQL Server really not capable of deciding that
select * from Alias1.db1.dbo.table1
and
select * from Server1.db1.dbo.table1
should be optimized and executed exactly the same when Alias1 is Server1, but that it is a distributed query ONLY when Alias1 is really referring to a remote server? I realize that the four part name is not necessary when I am referring to objects on the current server, but I am trying to write code that is server instance independent.
It just seems that if that is not possible, then the only way to create system independent stored procs that can run in dev, staging, and production environments and work with multiple databases on multiple servers is to create all sorts of scripts to regenerate all the procs whenever you move a database between servers?
If SQL Server is even close to the enterprise big iron server that MS now claims it is, it surely needs to support running in dev, staging, and production environments and work with multiple databases on multiple servers?!
I'm really looking for someone to tell me I'm missing something simple, and of course you can do this - but complex workarounds are invited too :-)
This is not something I am investigating as an academic exercise, I am already doing this, but I have to figure out how to do it better because with all these unnecessary distributed queries, performance is horrible.
Thanks
Sean

I know how to create an alias for a SQL server instance, so instead of MyServerMyInstanceName, I can type MyInstanceName into my SSMS connection box. But SSAS does not allow me to connect with the alias.
I've looked all over and found plenty of documentation that SQL 2005 and 2008 doesn't allow the use of instance aliases for SSAS. I've even found notes from Microsoft saying "we'll fix this in a future edition." I have not found any indications or notes as to whether or not this has been fixed.
Can aliases be created for 2012 SSAS? Or is this still not available?

I have some stored procedures that do updates using table aliases, like this:
UPDATE TableAlias
SET ColVal = 1
FROM RealTable AS TableAlias
WHERE TableAlias.ColVal <> 1
This allows me to include joins and stuff in the update (not shown) and make it all more readable for me.
It all works fine, and the SSMS parser says it's fine. But I also have another script which looks at sys.sql_expression_dependencies and sys.objects to find stored procedures with invalid object references (see below), and it's understandably saying that all of the above type stored procedures have invalid references.
SELECT
OBJECT_NAME(DEP.referencing_id) AS referencing_name,
DEP.referenced_entity_name
FROM sys.sql_expression_dependencies AS DEP
WHERE
-- Only validate local references:
(
DEP.referenced_database_name = DB_NAME()
[Code] ....
So I have a couple questions.
1. Is the UPDATE syntax I'm using kosher?
2. Can you recommend any updates to my stored procedure validation script that will better accommodate table aliases like mine?

I use DNS alias to access my database server:
server name is -> SRV100
DNS Alias is -> SQLPROD
I've noticed that, using Windows authentication, if I connect to the server using its server name, the DB Engine uses Kerberos authentication scheme (as it is supposed to do) but if I use Kerberos authentication, I see that the DB Engine uses the NTLM authentication
scheme
select client_net_address,auth_scheme from sys.dm_exec_connectionsÂ
I need to use DNS alias to connect to my server and I want to use Kerberso auth scheme.

basically, we have two databases, one with fix name, eg. DB1 in all environments, and another is named with prefix based on environment, eg. DB2_DEV, DB2_TEST, that is generated by some managed application.Â
Then we have queries or view/SPs residing in the first database, eg. DB1 that access database resources from the second database, DB2_***. Both databases are residing in the same SQL instance.
Currently, we have hardcoded the database name in the query but would prefer not to manually rename or write other scripts to update the query with the correct database name when deploying to other environments.
For example:
SELECT * FROM DB2_DEV.dbo.vAccounts
When deploy to TEST, we need to update the query to:
SELECT * FROM DB2_TEST.dbo.vAccounts
So, I looked at Synonyms but it seems it can only create 'alias' for tables or views, and not database.
Hence, last thought is to create self linked server, so I can write my query like below and setup the linked server accordingly.
SELECT * FROM SRCDB.dbo.vAccounts
Any consideration to think of, eg. performance, security, etc?

As a database developer, I have so many databases that I "own" scattered across various servers that it''s getting difficult to remember where all of my databases reside. It doesn't work that the DBAs have taken to some very hard to remember server naming conventions.
I was going to create aliases via the configuration manager, but it turns out the DBAs overwrite my entries each night with THEIR aliases and they won't add any for my use.
So I decided to simply add some records to my host file so that instead of having to connect to "SERVER-AD_DADF-DAFDASS" I can just use "CustomerA".
This solution seems to work until I tried to access a linked server. If I connect to the main server via it's actual name, I can hit the remote/linked server with no issue. However, if I connect to the main server using it's alias, connection to the remote/linked server fails with: Login failed for user 'NT AUTHORITYANONYMOUS LOGON'.
The linked server is set up to use current security context and I'm not logging into the alias any differently that I do when using the actual server name.

I have a bit of trouble getting values into one alias field, my code is below. I am trying to get values into the alias extension, Agent_ID is sometimes null, and so is agent_id2, however sometimes they both have values in them, and then only one of the values is every returned. When in the example below only Agent_ID (11111) is ever returned by I want both of them returned.
Agent_ID Agent_ID2
11111 22222
<code>
SELECT DISTINCT
CASE WHEN [AGENT_ID] is not null then AGENT_ID
when agent_id2 is not null then agent_id2 end as extension
FROM [AA_Helper].[dbo].[tblEmpData]

Using SQL Server 2000 Reporting Services and want to open new IE window to link to a site.
We are using IE 6.0.
I am using the following Navigation "Jump to URL" in report:
javascript:void(window.open('http://www.microsoft.com/en/us/default.aspx'))
This works as expected if I am not using the DNS alias to reference Reporting Services. But if I use the DNS alias when referencing Reporting Services, then when I click the link in the report I get the "Cannot find server or DNS Error" in the IE window that opens. Everything else works correctly in the reports when I use the DNS alias.
Anyone have a clue why this is happening?
Thanks, DR

We have an alias for dbo in various code areas, development/test/production. It was easy to tell the DBO alias
on release 6.5 but now on 7.0, the only way I can figure out if the userid is aliased to dbo is to sign on as the userid
and query 'select user_name( )' and if it returns dbo, I have the answer. Is there an easier way to do this by looking in a
system catalog or is there something else I am missing? Thanks in advance. Karen Suenram

In 6.5 you could alias someone as dbo, thus preventing an ownership chain break. In 7.0 there are roles, one of which is db_owner. I gave a user db_owner role, and they created a table. But no one else can see it? And he is listed as the owner in EM. How do I more effectivly mimic the dbo alias available in 6.5?

Hi All,
I've just installed an active/active sql cluster. Both are named instance hence if i need to connect to it, I need to use NODE1SQLINST1 and NODE2SQLINST2. Is there a way to just use NODE1 or any other single name to connect to the sql instance? I was looking at Alias but I can't get it working. Anyone has any ideas or suggestion for me? Reason why i want to do this is in an odbc connection, instead of using NODE1SQLINST1, I can use NODE1.
Thanks
