We are in desperate need to having some way to reference a static table in SQL. I'm assuming this maybe possible using a function but i'm not sure how to accomplish this.
For example I want to ...
-on SQL Server A (2005)
SELECT * FROM staticDB.someTbl
-on SQL Server B (2008)
SELECT * FROM staticDB.someTbl
then on each server have the real "staticDB" reference someplace
Hopefully this makes sense!
Thanks
EDIT
So when I have a stored procedure on our dev server it points to the dev db (via the function/var). Then on the prd server it points to prd db. Instead of having to remember to replace them every time. We can have one reference to this function/var and it would just work across both servers.
Something like a connection string equivalent, but for SQL.

I am a new database intern working with a access front end and SQL server backend database. The database was custom made for the company. One of my assignments is to take scripts and apply them to make four new tables. I am aware that I need to make a new query for each new table but I don't know if I should make the query in SQL server management studio or the frontend access program. I have tried copying and pasting the given scripts into a new query in access but I get an error message "invalid SQL statement expected 'DELETE', 'INSERT'...". I decided to try to break done the program a little bit and tested the first line
IF EXISTS (SELECT * FROM sys.foreign_keys WHERE object_id =OBJECT_ID(N'[dbo] .[FK_tblInstrumentInterfaceLog_tlkpInstrument]') AND parent_object_id = OBJECT_ID(N'[dbo].[tblInstrumentInterfaceLog]'))
but the same error message keeps popping up. I even tried just SELECT * FROM sys.foreign_keys, and I got the error message "could not find file...". I am very much a beginner and any guidance would be appreciated.Basically am I supposed to be applying these scripts the server SQL database or on the front end access program?
Are you using a pass-through query? i.e. not just a select query. Access needs to know where to send the query and since you are using TSQL not Access SQL this needs to be executed on the server.
Normally when you query a linked table the information of how to get the data (the connection string) is tied to the table. But for this kind of query you'll probably need to tell Access explicitly. Unless you are using an ADP/ADE, then the connection info travels with the program not the table.
As a general rule, you use SQL management studio (SSMS) to create and run those scripts. So the general accepted approach here is such scripts will not be placed in the front end. As noted such scripts if for some reason must be placed in the front end, then you have to create them as pass-though, but EVEN in this case you want to use the SSMS to create such quires.
So the answer here is you create the new scripts and make table queries in the back end, or in this case using the SQL server management studio.
The syntax checking, query editor etc. in recent versions of SSMS now has auto-complete etc. and you can test/write/update those scripts in SQL server. Once you have such a query or even several of them, then the resulting “several” statements can be pasted into a front end query that been created as pass-though. If you do not use a pass-though query, then you are creating and using and assuming client side SQL (JET (now called ACE)).
The client side has it own version of SQL syntax, and it is NOT 100% compatible with the SERVER SIDE. If you writing SQL in the client that is NOT pass though, then you using a linked table to SQL server. These linked tables thus will use local (JET/ACE) based SQL queries. The ODBC driver thus translates this SQL into server side compatible syntax. However the JET/ACE sql syntax is very limited when compared to SQL server and no server side commands exist in this SQL syntax for the client data engine (JET/ACE)
So for many quires, you will and can simply build such queries using the Access query builder.
However for SQL that needs to run 100% server side then such quires has to be setup as pass-though and are in most cased built + tested using SSMS.
Is it possible to copy data from one server to another using a T-SQL script? We have a code promotion process that makes using the import wizard less than optimal for our team so I am looking into a script I can simply have someone run in Management Studio that will do the trick.
Yes,
First create a Linked Server to other server, then you can access the target server by 4 part Names, for example:
Insert into Server2.Database2.dbo.MapTable1 select * from table1
p.s you can add linked server by sp_addLinkedServer
I need to query a table from another SQL Server on a different server but same domain, but I am not sure how I will be able to do it.
I tried solution given in this answer Can I create view in my database server from another database server but it doesn't work for me as I got SQL Server 2000 (please don't hate :-) ).
When I try solution given then i get this error,
Line 23: Incorrect syntax near '-'.
which is because command is not compatible with SQL Server 2000.
Edit
SELECT * FROM AnotherServer.AnotherServerDatabase.Server.Table1
you can link the servers and run cross server queries as long as you put the server name before the DB your running the query on.
For example
SELECT * FROM "linkedserver".dbo.aTable
(without "" marks )
bear in mind different server versions though. I run cross server queries from 2008 to 2000 servers and its a pain adapting :)
I have database connection to database DB1. The only thing I could do - execute any t-sql statements including using stored procedures. I want to export the specific table (or even the specific rows of specific table) to my local database. As you can read abve, DBs are on diffrent servers meaning no direct connection is possible. Therefore question: Is it possible to write query that returns the other query to execute on local server and get data? Also note, that table contains BLOBs. Thanks.
If you have SQL Server Management Studio, you can use the data import function on your local database to get the data. It works as long as you have Read/Select access on the tables you are trying to copy.
If you have Visual Studio you can use the database tools in there to move data between two servers as long as you can connect to both from your workstation.
Needs Ultimate or Premium though:

RedGate has some usefull tools too:

Maybe you should ask at https://dba.stackexchange.com/ instead.
If you can login to the remote db (where you can only issue t-sql), you may create linked server on your local server to the remote and use it later directly in queries, like:
select * from [LinkedServerName].[DatabaseName].[SchemaName].[TableName]
When running a SQL statement or a stored procedure on a database, can you connect to an external database and pull data from there?
something like:
SELECT a.UserID, b.DataIWantToGet
FROM mydb.Users as a, externaldb.Data as b
You'll need to setup a Linked Server instance. Then you can reference the external database as though it were a SQL Server database.
Yep -- there's two methods: either use the function OPENROWSET, or use linked servers. OPENROWSET is useful for ad-hoc single statements, but if you're going to be doing this regularly, read up on linked servers as they allow you to do exactly what you've specified in your SQL Statement ... e.g.,
SELECT database.owner.table for local data
SELECT server.database.owner.table for remote data
And yes, you can mix and match to do joins twixt local and remote. Note though that you'll need to be caureul if you do joins against large tables that exist on the remote server as the query could take a long time to exexute...
Yes, you can. You should take a look at linked servers for starters. You can also use OPENROWSET to hit them directly with no linked server.
Easiest way :
Click connect to server
when it asks for server name use:
192.168.X.X,1433\SQLEXPRESS insted of YOURPC\SQLEXPRESS
(The ip and opened port of target sql server)
Type correct username and password
Done!
