Setting Up A Synonym In SQL Server 2005
Aug 15, 2006
Can anyone tell me why I am getting this error when I try to select * from a table through a newly created synonym? I have admin rights to both db, but they are on separate servers.
<Error>
OLE DB provider "SQLNCLI" for linked server "srvDEV" returned message "Communication link failure".
Msg 10054, Level 16, State 1, Line 0
TCP Provider: An existing connection was forcibly closed by the remote host.
Msg 18456, Level 14, State 1, Line 0
Login failed for user 'NT AUTHORITYANONYMOUS LOGON'.
</error>
<code>
CREATE SYNONYM ARContractTerms_syn FOR srvDEV.EricsAdeptCastle.dbo.tblARContractTerms
SELECT * FROM ARContractTerms_syn
</code>
Am I running into schema problems?
Thanks all

I'm using SQL Server 2008R2. I am developing a database which requires access to data from other servers. So far I have been creating views using OPENQUERY (where there's a performance benefit) to select specifically the columns I want. Generally, for my purposes, I find these OPENQUERY based views to perform better (some times significantly so) to simple SELECT <COLUMNS> FROM <SERVER>.<DATABASE>.<SCHEMA>.<TABLE> WHERE <Where clause Statements> format views. My understanding is that this is because an OPENQUERY "pushes" the query processing to the remote server and simply returns the final result set to the local server i.e. there's no cross-server join/synchronization going on.
My question is, if I were to create a Synonym for a table object on the remote server, where does the processing happen if I query from this Synonym or create a join with this synonym to a table in my local database?Essentially, I am trying to understand if there are any "hidden gotcha's" primarily from a performance perspective, to using synonyms.

A heavily-selected database will be in an inconsistent state for several hours during a batch process. For that time, a database snapshot is created and accessed instead. To allow constant client read access to the database, a database that only contains synonyms exists. Those synonyms point to the main database except during the batch process, at which time they point to the database snapshot.
To switch the synonyms, each synonym is dropped and then created pointing to the database snapshot (after its creation, of course). The drop/create occurs inside a transaction. Roughly, the SQL looks like this:
SET XACT_ABORT ON;
BEGIN TRANSACTION;
DROP SYNONYM [dbo].[some_proc];
CREATE SYNONYM [dbo].[some_proc] FOR [snapshot_db].[dbo].[some_proc];
GRANT EXECUTE, SELECT ON [dbo].[some_proc] TO public;
COMMIT TRANSACTION;
When the batch update is completed, the process is reversed with "snapshot_db" replaced with "regular_db". The SQL snippet above is dynamic SQL. What I've pasted is the dynamic SQL that is executed as a single batch.
While this switch is happening, clients are accessing the procedures through the synonyms, potentially at a high request rate. Testing reveals that clients can get the error:
Error=-2147217900, Id=0, Meaning=IDispatch error #3092,
Source=Microsoft OLE DB Provider for ODBC Drivers,
Description=[Microsoft][ODBC SQL Server Driver][SQL Server]Could not find stored procedure 'dbo.some_proc'.
This error only occurs once. If the same SPID retries its request and the transaction has not completed (for testing, a delay was added), then it blocks until the transaction completes.
Any way to prevent it besides a client-side retry?

Is there any setting to indicate Unicode data to handle, so that no need to exclusively use Unicode data types ( ex nvarchar ).
I need to execute both Unicode and non Unicode SQL statements with in one environment. I don't want to create seperate database again.
Please let me know if any one had approached on SQL server this way. I am looking the way Oracle provides where you don€™t need to declare the data type of the column as Unicode type in table definition but can indicate when running a query to manipulate that field as Unicode field.
Thank youSunil

My manager has asked me to install and configure Source Safe so that our team can check out stored procedures, (and other objects), and check them back in when we are finished working on them.
I'm not familiar with Visual Source Safe. Does SQL Server 2005 work with Visual Source Safe in such a way that I can check out/in SQL Server objects such as procedures?
If someone knows the answer, or perhaps an existing thread that covers this, please let me know.
Thank you for your time!

I have recently upgraded my databases from SQL 2000 to 2005. In 2000, I could set the network affinity so that sql server was only accessible from one of the two network cards. I cannot find how to do this in sql 2005. Is there a way?
In my installation, I have two network cards in each server. The "A" network adapter connects to the "A" hub, and the "B" adapter connected to the "B" hub. Traffic on trhe "B" hub is my private, non-routable network, This is where I want the SQL Server traffic to run. The A hub traffic is the public network. This gives me the ability to isolate SQL Server from the outside world.

Im trying to setup replication between two 2005 standard editions. They are on the same LAN and installed equally + SP1. They are installed as named instances (with the same instance name MSSQL01). Remote access is allowed and TCP/IP and shared memory and I can connect between them.
SQL1MSSQL01 is configured as the publisher & distributor and the snapshot is done. When Im using the subscriber wizard from SQL1 to create the subscriptions and add SQL2MSSQL01 as a subscriber the connection fails to the remote server.
The error message is:
TITLE: Connect to Server
------------------------------
Cannot connect to SQL2MSSQL01.
------------------------------
ADDITIONAL INFORMATION:

When I do a manual connection to SQL2 using the server managemnet studio on SQL1 I cannot connect using the instance name e.g. SQL2MSSQL01, it works only when only using the server name e.g. SQL2. Then I have full access both when using a windows or SQL user.
When trying with using the server name only when setting up the subscription, I got a error saying that I need to use the full name.

I can also mention that theese servers are cloned from another server and I needed to drop the old servername and add the new servername (sp_addserver) on both servers to get the publisher to work.
When I try to setup the subscription from SQL2 and add SQL1 as a publisher I get the same error.
Any one have any idea what it can be?

Hi there,
I am looking for a way to have SQL server accept incomming e-mails and store the contents of the e-mail into the database. I was doing some research on the subject of recieving emails from a SMTP server with the server having an account, but it looks like there are no information on the subject.
Is this possible? Or do I have to use some sort of work around hack?
Thanks in Advance,

Hi
I have a setup where I need to replicate the database which is actually subscribing from another database. The current setup is all in SQL Server 2000. I need to now setup a Distrbutor on a SQL server 2005 and publish the database using this distributor to another server on SQL server 2000.
Has anybody done this before. If yes what will I need to check. Can you please let me know :-
1) SQL Server 2000 which SP should be installed to support this enviroment.
2) SQL Server 2005 which SP should be installed to support this environment.
3) Any thing that I need to look out for.
Thanks for any inputs on this.

I have a Sybase Adaptive Server Enterprise server which I need to set up as a linked server in SQL Server 2005. The Sybase server is version 12.5.2, and the Sybase ODBC driver version is 4.20.00.67. I have already installed the Sybase client software on the server.
I also created a SystemDSN on the SQL Server to connect to the Sybase server. I tested the connection and it was able to connect.
I ran the following code to create the linked server:
<code>
EXEC master.dbo.sp_addlinkedserver @server = N'LinkedServerName', @srvproduct=N'Sybase', @provider=N'MSDASQL', @datasrc=N'Sybase System DSN', @provstr=N'"Provider=Sybase.ASEOLEDBProvider;Server Name=servername,5000;Initial Catalog=databasename;User Id=username;Password=password"'
</code>
I then ran sp_tables_ex to make sure I could view the tables in the Sybase database. Here is the error message I get:
<code>
OLE DB provider "MSDASQL" for linked server "LinkedServerName" returned message "[DataDirect][ODBC Sybase Wire Protocol driver]Error parsing connect string at offset 13. ".
Msg 7303, Level 16, State 1, Procedure sp_tables_ex, Line 41
Cannot initialize the data source object of OLE DB provider "MSDASQL" for linked server "LinkedServerName".
</code>
Any ideas what is happening here?

Hi!
I have a problem changing the language setting to swedish on sql server 2005 compact edition. The thing is that I'm using a language dependent format: '1998-02-28 14:23:05' (Numeric) when saving and I rather don't want to change this format, because it's a lot of work. (The default setting on the database seems to be us-english, which has the format month-day-year and there by gets wrong for me).
As I understand, this is detemined by the language settings on login. So I set this by using the 'locale identifier' (sv-SE) in the connection string to the CE database, but when I try to save the data, the datum is still interpreted as us-english format.
(The application I'm running have been upgraded from sql compacte edition 2.0 where this worked just fine, though without specifing any language settings in the connection string.)
Appreciate any help!

During an install of SQL Server 2005 Express setting the sa password does not work consistently. The install is being run as administrator and I am using an .ini file to pass the settings,
SECURITYMODE=SQL
ADDLOCAL=ALL
SQLBROWSERAUTOSTART=1
SQLAUTOSTART=1
INSTANCENAME=DBSERVER
SAPWD=Westtech#1
and while most times it works correctly, occasionally, maybe 4 out of 10 times it fails to set the password and I have been unable to find any warnings or errors in the logs it generates.
We are coming up on release and this is causing us some real problems. Does anyone have any ideas, something I could look at?

I need to set up 1 new user in SQL Server 2005 to be able to read specific tables in a db (db1).
The user will connect from MS access using odbc links (SQL Native client ot SQL Server driver)
I've tried to set up one and once logged on from the user workstation, I can only see sys. tables and INFORMATION_SCHEMA tables.
None of the required db1 tables appear.
under Security/Logins I've created User1:
SQL Server auth. with password
default db = db1
server_roles = none
user mapping = map, db1, user1,dbo
securables = none
status = grant, enabled
on the access db, the odbc link was set up with default db = db1
Why can't I see any of the db1 tables?
How can I restrict access to the sys. tables?
Thank you

Hi all,
I'm a newbie to Reporting Services so please forgive my ignorance...
I've recently installed SQL Server Express 2005 with Reporting Services on my Vista Business Notebook (with no network connections) and have installed VS C# Express as well as the Business Intelligence Studio to create reports.
My C# application can connect to SQL Server fine, however, the reports I created with Business Studio refuses to deploy to the server due to the following reason:
"The permissions granted to user 'localhostJenny' are insufficient for
performing this operation".
I find this odd as I've been able to deploy reports on my other Windows XP machine (with SQL Server Express) no probs at all. Additionally, I cannot see the 'Site settings' link within Report Manager (Web) that I'd normally get with an admin account (i.e. on my Win. XP machine). Various sources indicate that my account has insufficient access rights to view this.
Having browsed through seemingly endless blogs and forums, I suspect that my local account has not been configured to access the Report Manager web client to publish, manage and administer the site.
I have tried the surface area tool for SQL Server, but I suspect that this is relevant only to SQL Server DB access and management. Adding an administrator here does nothing.
The question is, how can I grant access to myself (local account) to allow me to publish reports via business studio, and at the same time - administer Report Manager Site Settings - on my vista notebook??
I would be extremely grateful for any help on this matter - I've tried ceaseless reinstallations, but to no avail!
Many thanks in advance,
Jenny

Suppose that a synonym foobar exists pointing to the table foo.bar. I also have a table with the same name in my schema. (mpswaim.foobar)
If I do a select
select * from foobar
Which table does the select run against? mpswaim.foobar, or foo.bar?
In Oracle, mpswaim.foobar would win, and we used this to all ow individual developers to have their own version of application tables during development.

My windows Regional and Language options €“ English (United Kingdom), Sort date format is dd-MM-yyyy.
When converting the date time in Sql server is using the mm-dd-yyyy format. But I€™m supplying the dd-mm-yyyy format date time.
I tried number of things none of them worked for me
1. Tried changing the default language and get the date time format
- exec sp_configure 'default language', 2057
reconfigure

EXEC sp_defaultlanguage 'my user name', 'British'
- did not work
(Ref: http://www.cactushop.com/support/UKUS-date-format-issues-with-MS-SQL---conversion-errors-or-blank-pages__592__.htm)

- did not work
3. Every thing in the Regional and Language options to UK and British with the date time format input language keyboard and every think else I could think of, which could link to US English or US date format --------- Did not work
4. even went into the extend of modifying the date format on a Windows machine for new users account by editing the HKEY_USERS registry key and creating a new user - Did not work
(Ref: http://www.windowsitpro.com/Article/ArticleID/39407/39407.html )
5. Uninstall and reinstall SQL server express several time and did the steps 1 €“ 4 where applicable €“ did not work€¦.
If anyone has any idea of what I have to do to change the date time format in the SQL Server 2005 to use the dd-mm-yyyy format for dates....
Please help me or point me in the direction in which I have to look for an answer.

Hi all. Informix and DB2 support something called synonyms that allow you to basically create sort of an alias for a table at the database level. Think of it sort of as a shortcut or link to a table. Does SQL Server 2000 have a similar ability and if so how?
I know someone will ask why you want to do this, so heres a quick example:
If you have one legacy application that expects to write to one particualr table, but you wish to partition that table across several tables, you can break table1 up into tablea,tableb,tablec and then create a synonym called table1 that would point to only the appropriate table at the appropriate time. This way you can break a huge HUGE table up into logically discreet smaller tables and manage the creation of the appropriate synonym in some wrapper that sits in front of the legacy application...thus allowing you to retool a table that has outgrown its original design without having to crack open dreaded legacy code.
So, anyone?

I ran the following command to create a synonym for a function -
create synonym testfunc for myschema.myfunc
Then testfunc will be created in the dbo schema. When I call this function from my stored procedure by 'testfunc', I received an error indicating 'testfunc' is not a recognized build-in function name. If I call it by 'dbo.testfunc' then it will work.
If I create a synonym for a table, I can access the table using the synonym in my stored procedure without any problem.
Is it true that synonym works differently on tables vs. functions?

I may just be completely missing something here but, when I view a query plan from a SQL statment that involves a join with a synonym I do not see any reference to the synonym or the underlying table referenced by it in the query plan? Any thoughts?

I am working with SQL Server 2005, here is what I am doing:
declare @cx as varchar(100)
set @cx = substring(db_name(), dbo.instrrev('_', db_name()) + 1, datalength(db_name()) - dbo.instrrev('_', db_name()))
exec ('CREATE SYNONYM tblsynonym FOR ' + @cx + '..TableName')
---Procedure
drop synonym tblsynonym
The application i'm working on uses stored procedures that will at some point be called by more than one user at a time. At the start of the stored procedure the synonym is created and then it is dropped when the procedure completes, the issue is this: if two users access the same stored procedure at the same time then the first procedure will create the synonym and the second will fail because the syonym already exists.
Here is what I would like to do:
declare @cx as varchar(100)
declare @timestamp as datetime
set @cx = substring(db_name(), dbo.instrrev('_', db_name()) + 1, datalength(db_name()) - dbo.instrrev('_', db_name()))
