How to access network file in SQL

How can I access network XML file from SQL server store procedure?

A procedure which is accessing local file "C:\xyzConfig\xyz.xml" as one of the string parameter.

Now my SQL instance is changed to different server but XML location is same.

I tried "\\SERVER100\c$\xyzConfig\xyz.xml" but It won't work.

Error throw as



"....... could not be opened. Operating system error code 5(Access is denied.)."

here how I resolve with your help,

1) I have a web application on Server100 with IIS & etc..
2) SQL instance is a cluster on Server400 which doesn’t have IIS & etc..
3) make share folder on Server400, Drive X, then I can access file from SQL as local file. Share with read & write permission for domain users
4) but no IIS on Server400 so, it is not allow me to set Web Sharing folder.
5) So, From web app. i have to set up





6) after all I can access file from both process.

MS SQL Server 2008 new features

Data Compression

SQL Server 2008 gives us the ability to compress data and save on disk space. Without getting into many specifics, data in SQL Server can be compressed at the page level. This means that when you compress a table, it actually does it a page at a time. I'd advise you to tread lightly with data compression. You should make sure you do your research and testing before implementing compression in your environment. That said, when disk space is at a premium, you can use this feature to pack more data onto the platters.

Backup Benefits
SQL Server 2008 provides backup compression. With backup compression, you have the savings of file size built right into the native backup.

To use backup compression, you just need to add the WITH COMPRESSION option to a BACKUP DATABASE statement as shown below:

BACKUP DATABASE Adventureworks2008

TO DISK = 'D:\Backup\AdventureWorks.bak'

WITH COMPRESSION

Here's an example of the compression ratio: a backed up 965MB database without compression resulted in a 636MB backup file. Using compression, the same database produced a 147MB backup file.

Learn to Merge
The new MERGE statement in SQL Server 2008 obviates the need for "IF-THEN" logic to decide whether a row needs to be inserted, updated or deleted. MERGE allows you to take care of the logic and the modification all in one shot. What's more, you can compare an entire record set all at once instead of going row by row. Here's a quick example of using MERGE:

MERGE tbl_address AS current_addresses

USING (

SELECT customer_objid = address_label,

addressline1, addressline2, city, region, country, zip

code, is_deleted

FROM @addresses)

AS

source_addresses(address_label, addressline1,

addressline2, city, region, country, zipcode,

is_deleted)

ON

(

current_addresses.address_label = source_address

es.address_label

)

WHEN NOT MATCHED THEN

INSERT (address_label, addressline1, addressline2,

city, region, country, zipcode)

VALUES (source_addresses.address_label,

source_addresses.addressline1,

source_addresses.addressline2,

source_addresses.city, source_addresses.region,

source_addresses.country, source_addresses.zipcode)

WHEN MATCHED AND source_addresses.is_deleted

= 1

THEN DELETE

WHEN MATCHED THEN

UPDATE

SET address_label=source_addresses.address_label,

addressline1=source_addresses.addressline1,

addressline2=source_addresses.addressline2,

city=source_addresses.city, region=source_address

es.region, country=source_addresses.country,zip

code=source_addresses.zipcode

The USING section defines the "new" data, in this case a table variable. The ON section defines the join between the new and existing data. Finally, you have a series of MATCHED statements that do things like insert WHEN NOT MATCHED, update WHEN MATCHED or delete WHEN MATCHED and some other value indicates delete. This is a real time saver, and the syntax is much cleaner that the older alternative of using homegrown logic

MS SQL (7/2000) database "Suspect Mode" / "Emergency Mode" / "Error 1813

Recovering MSSQL from "Suspect Mode" / "Emergency Mode" / "Error 1813"

For SQL 2000 database some time database goes into suspect mode, when you trying to delete database directly.


sp_configure "Allow updates" , 1
go
update sysdatabases
set status = status & ~ 256
where (name = 'SuspectDatabaseName')
go
sp_configure "Allow updates" , 0
go

* user must be SQL admin user.
it will restore database.

if still not works go for hotfix

click here http://support.microsoft.com/kb/889266

try this http://www.gerixsoft.com/node/24
(good post)

keep in mind

The issues that are fixed by this hotfix package.
The prerequisites for installing the hotfix package.
Whether you must restart your computer after you install the hotfix package.
The files that are contained in the hotfix package।


"Suspect Mode" --> "Emergency Mode"
Open Enterprise Manager,
Right click onto your server node, - an SQL Server Properties dialog will popup,
Enable "Allow modifications to be made directly to the system catalogs" option
Now proceed to the sysdatabases table in the master database, locate your database row and put 32768 into its status column
Restart SQL Server and refresh Enterprise Manager
Open Enterprise Manager - the database will be marked as "Emergency Mode"
These articles explain the trick behind suspect and emergency mode:http://support.microsoft.com/support/kb/articles/Q165/9/18.ASPhttp://www.swynk.com/friends/knight/unmarksuspect.asphttp://support.microsoft.com/support/kb/articles/Q180/5/00.asp
3. "Emergency Mode" --> "Normal Mode"
Now your database is in "emergency mode". Disregard Enterprise Manager does not show tables, views and procedures - use Query Analyzer's Object Browser instead.
"Emergency mode" means database is locked against any modifications, it is readonly forever. There is no way to bring "emergency" database back to normal state. All we can do is copy all data from it into new database.
Create new database (pubz)
Create new DTS package
Use "Copy SQL Objects" task to transfer data from old database to new database (pubs->pubz)
Execute the DTS job & enjoy!
Note that there might be complex dependencies between database objects, so Copy SQL Objects task might not work properly. For example: view A is dependent on view Z; Copy SQL Objects task will try to create view A first, -- that will fail, because view Z does not exist yet.
4. "Error 1813" --> "Suspect Mode"
If you receive "Error 1813", this probably means that you are trying to attach database you have improperly detached, or haven't detached at all. Only successfully detached databases can be successfully attached back.
Create new database using the same name and file location as database that is failing to attach
Stop SQL Server
Copy non-attachable data files over the new ones
Delete log files
Start SQL Server
Open Enterprise Manager - the database will be marked as "suspect"
Once your database is "suspect", use instructions outlined above...
Note that database will be marked "suspect" only if transaction log contained active sections. To illustrate the problem for 100%, run a few inserts against the database before deleting transaction log.
