I am creating partition function and schemes.
In SQL Server 2008, it only defines range partitioning and not list partitions.
Dont we have list partitioning in SQL Server?
I am using SQL Server 2008 Enterprise edition.
There is no List Partitioning in SQL Server 2008. But you can fake it into creating one using the LEFT clause.

how i can link that server?
can anyone give me solution?
i am using SQL Server 2012 and would like to implement FileTables feature in application. how many FileTable we can create in one Database in SQL Server 2012?
The number of tables allowed in a single database is limited to the total number of object, which can't exceed 2,147,483,647. I've never run across any article that diferentiates between regular tables and file tables.

I never seen this, but is it possible to have one SQL call join data from Oracle and SQl Server?
Yes, Oracle and SQL Server both have functionality that allows to connect to other databases, including different vendors. In Oracle terminology, it's a database link instance while on SQL Server it's called a Linked Server instance.
The syntax to reference the instance is different between Oracle and SQL Server though. IE:
Oracle:
SELECT t.*
FROM table_name#database_link_instance t
SQL Server:
SELECT t.*
FROM linked_server_instance_name.database_name.schema_name.table_name t
does MySQL support the linked server concept?
No, the closest MySQL has is the FEDERATED engine, which is only for connecting to remote MySQL instances.
PostgreSQL?
PostgreSQL has dblink. Last time I looked at dblink (pre-v9 release), it only could connect to other PostgreSQL instances.
Yes- both Oracle and SQL Server support the linked server concept. That allows you to reference the other server using a 4 part name. For example:
select *
from LocalDb.Schema.Table
cross join
OracleLinkedServer.RemoteDb.RemoteSchema.RemoteTable
I have a star schema but SQL Server 2005 always uses the clustered indexes to access a table. What parameters do I have to set to enable this optimization.
According to http://blogs.msdn.com/sqlqueryprocessing/archive/2007/04/09/how-to-check-whether-the-final-query-plan-is-optimized-for-star-join.aspx and the DWH datasheet of SQL Server 2005 both claim, that SQL Server 2005 support this feature.
What edition do you use? IIRC star query optimization is ONLY in the enterprise version of SQL Server 2005.
Is there a way to get SQL Server 2005 to query 3 or more separate Access databases (each returning 1 record) in one SQL statement?
Yes, but it will require you to create a Linked Server instance for each Access database. See here for details about creating Linked Server instances on SQL Server 2005 to MS Access.
Once you have those in place, you can query SQL Server and it will pass on the queries to the respective Access databases based on using the Linked Server instance notation when specifying tables in your SQL Server queries.
What you want is a Linked Server for each of the Access databases.
Just be aware that in SQL 2005 64-bit you won't be querying current versions of Access or Excel through linked servers any time soon.
Yes, set them up as linked servers using sp_addlinkedserver.
