I have a utility I wrote which can backup/restore my database as wellas schedule backups. This has always worked pretty well except when Itry to backup to a USB Flash Disk. When I use one of these the backupfails. If I backup to the C:/ drive then copy it over to the disk itworks fine but when SQL Server tries to do it, it can't.I am simply doing the following:BACKUP DATABASE MyDatabase TO DISK = 'E:/backup.dat_bak' WITH INITAnyone know what could be going wrong?

I have a database [CarlosDB] that currently has it's .MDF on E: and I need to move the x2 .NDF data files off C: to E:data using a single T-SQL statement:
Code:
database_id file_id db_name disk_path status size read_only
----------- ----------- --------------------------------------------------------------------------------------------------------------------------------
7 1 CarlosDB E:dataCarlosDB.mdf ONLINE 384 0
7 2 CarlosDB_log L:logsCarlosDB_log.ldf ONLINE 128 0
7 3 CarlosDB_2 C:sqlCarlosDB_2.ndf ONLINE 128 0
7 4 CarlosDB_3 C:sqlCarlosDB_3.ndf ONLINE 128 0
(4 row(s) affected)
Looking at the file configuration above, what would be the most logical way as a DBA / SQL Server 2014 Std to move the NDF files to live w/ the MDF file using:
Code:
EXEC master.dbo.xp_cmdshell 'copy c:sqlCarlosDB_2.ndf e:dataCarlosDB_2/ndf'...
but cleanly using a single T-SQL statement? properly formatting a single T-SQL query to use the xp_cmdshell system stored procedure.

I haven't found the definitive answer on how or if this can be done without removing replication. I'm thinking ALTER DATABASE modify_file is the way to go. Anybody know if this will work or a better way to go about it?
Thanks

Hi There,
Can I store flash files in the database. I have a table with one of the columns as varbinary datatype. Previously, I was saving images (as filebytes) into this column. But now I need to implement something to store the flash file. So, is it possible to store flash files in the database and retrieve them and display them in an asp.net page?
Thanks a lot for your suggestion!!

I just upgraded SQL6.5 standard(Installed 7.0 and ran Wizard to upgrade dbs) to SQL7.0 by running the exe file.
It turned out that the MSSQL7 folder is follen on Drive C instead of Drive D which is what I wanted. When I was running the upgrade exe file, there was no prompt to ask me the right path.
How could I have the MSSQL7 folder installed on D drive?
Thank you for help

All,
I'm writing to ask if anyone knows whether or not MS SQL server stores in any system tables the association between a database and the drive letter/directory path where its corresponding MDF/LDF files are located.
Thanks,
Isaac

Howdy y'all! :)
I have been instructed to move a large database we have on one of our servers off the current drive (local RAID-5 driveset in the server) to a EMC "drive" (logical drive, off-server).
I know one option is to back up the database, delete the database, re-create the db using the new drive for data/log files, then restore the database.
However, I was wondering if it would be better to just detach the DB, move the data/log files, then reattach to them?
Is it half-doz of one, and 6 of the other?
How should I go about this dastardly deed?
Off to poke around in BOL, but thought I would post first in case it's an incredibly easy answer for y'all
Thanks!

We have a cluster with two nodes and two instances of SQL Server 2012 Standard Edition running on them. Volume W: is a Fusion-IO card.
On one of these nodes a lot of database names are showing up in the resource monitor as *.mdf files (W:0MSSQL1…).
How and why SQL Server is using these files? They only show up on one of the nodes having more load.
Volume I: is the volume where the transaction log is written so we can explain these files.

Documentation that supports the placement of Tempdb files on the root of a drive, i.e T: instead of T: empdb. I am positive this is not a best practice, but when challenged could not find any documentation that would support that view.

Hello guys and girls. I have installed SQL Server 2005 Standard Edition and I have specified that the databases should be created on the K: drive. This is okay but now I need to move all the transaction log files (.ldf) to the L: drive. I have already changed the default location for the log files to point to the L: drive and the new databases that were created after the installation have their transaction log file correctly in the L: drive but now I need to move transaction log files for the master, model, temp ... databases. How can this be done? And are there any gotchas?

Hello,
I need to move all log files for my SQL 2005 databases to another drive. I don't wish to shrink the files, I need to move the logs to another drive spindle. I did find an article (Article ID: 224071) that describes moving both the database and logs using sp_detach and then sp_attach. What is the best way just to move the logs to another drive on the same server, and that keeps the databases in their original location?
Thanks.

I have two databases on a Production Server that I want to Log Ship to a Test Server. According to the sys.master files the physical File Location is on an E drive. Early attempts at Log Shipping these two files error'd out due to space issues on the E drive (one Log Shipped and then one err'd out). I was subsequently informed from the server group that they would prefer that I Log Ship these two database files over to the M Drive where more space is available. In fact, they modified the Server Properties / Database Settings / Database Default Locations (for Data and Log) to the larger M drive (I'm not really sure why they just don't increase the E drive space but there is proabably a good reason).
Okay, so now my problems have been solved. Easy enough. Now I deleted the successful Log Shipped database and started from scratch. However, as before, one db restored and one failed (due to space issues). Apparently, both db are pointing towards the E drive. How is that possible?
So here I am with one successful database and the normal sys databases pointing to the E drive. What is the best way of approaching this move to the larger and preferred M drive?

We have a package that is using a ForEach loop container to access files on a network drive. For some reason I am getting a message that the ForEach enumerator is empty and did not find any files that matched the pattern. For the pattern I left the default *.* for testing purposes. I have specified the file folder as \remoteserverfilesharesubfolder and also as \remoteserverc$filesharesubfolder and have gotten the same message. However when I map a network drive and set the file folder to the network drive it finds the files. Is this a permissions issue?
After I finish processing the file I want to move it to a new directory. Once this is deployed in production, the package will not be running under a domain account and probably won't have access to the network folder. Is there any way to specifiy in the connection manager itself that it should use a specific account to access the folder?
TIA,
Sabrina

The MDF and LDF files are placed in SSD drive and tempdb files are placed in HDD drive. Snapshot isolation is enabled on the database. When a script is executed to insert data with NULL value to a table which has NOT NULL column, the transaction fails and then a log undo happens which fails and takes the database to suspect mode.
But when the MDF and LDF files are placed in HDD drive all this do not happen. The transaction just fails.

Hello.
One of our hard drives has crashed and as a result we have lost our master mdf/ldf & user db mdf/ldf files. It's not that a critical system by any means, but if the hard drive crashes and the master mdf/ldf files & user db mdf/ldf are lost, is there any way of restoring the system?
I'm thinking we probably need to re-install Enterprise Manager completely, and re-install the user db from a backup.
Any advice/suggestions would be much appreciated.
Thanks in advance,

Is there a way to get access to the files on the shared drive from either of the nodes when the SQL Cluster is shut down?
It doesn't look like there is, but hoping there is some trick. I see how it can be done with a Windows Cluster but not a SQL Cluster.

Hi
I have been trying to use openrowset with a shared drive, and even though the share has "full control" permissions granted to "everyone" and the accout that SQL runs under has been granted explicit full control permissions I am unable to open the file which itself has no security on it.
Can I not use a \ path and only use mapped drives?
Thanks
below works...
SELECT * FROM OPENROWSET('Microsoft.Jet.OLEDB.4.0','Excel 8.0;Database=C:5People.xls', [Sheet1$])
below doesn't work...
SELECT * FROM OPENROWSET('Microsoft.Jet.OLEDB.4.0','Excel 8.0;Database=\cluster02FileManager5People.xls', [Sheet1$])

I proposed on a new server that we separate Data Files, Log Files, tempDB, Backups, etc. onto separate LUNS on a SAN with High Speed Solid State Drives.I was told that with the new technology with solid state SAN's that it would decrease performance and that it did not work the same way as it did when you had RAID 5's etc.I thought that if things were cared out correctly by a SAN Administrator they would know how to configure for optimal performance.

Hi,
I hope somebody here can help on my problem.
I wrote a MFC application using sql ce and is running prefectly smooth on wince and PPC 2003.
But when i deploy it to Windows Mobile, the database performance drop dramatically.
I knows the drop on performance is due to the I/O speed on the flash memory.(The previous mobile os are using ram instead).
Is there any solution or work around which I can solve this problem.
Recently i solved the performance issues on "insert" to DB by using a commit buffer(Instead of commit to the sdf instantly).
But how about the "select" performance? It's too slow which take about 3 sec to select a record from the DB.
Does Microsoft provide any suggestion on the sqlce perofrmance on windows mobile?
Thanks
Keith

Hi,
I have a question about using SSCE with flash memory. Our CE components equally allocate the write access to the memory location. But write access is guaranteed only 10000 times per memory cell.
So I need to know
1. what changes are made to the file system if I add an entry to a table?
Is this entry the only information added to the file system?
2. What happens if I delete an entry? Will SSCE optimize the data in the filesystem?
Thanks a lot for helping.
Regards Flo

I'm working on a project where the client wants us to create custom charts which have features not found in the standard Reporting Services charts. I would like to use flash to build this and have found an existing flash charting package for which I have the code and which I plan to expand.
Here's the problem:
The client wants to include these charts in his Reports. Is there some way to add a flash control to a report so that it will appear on the web page as a fully-functional flash presentation, which can then be included when printing or exporting?
The alternative, would be to figure out some means of generating the chart using flash outside of the report, exporting a bitmap of the chart and then saving the bitmap to a known location on the file system so It can be referenced by a report. This has some serious complications, and may not be feasible.
Any ideas?

Hello everyone,
I'm currently developping a windows .net compact framework application which is basically a local datalogger.
Since my application will log data to the database (located on compact flash card) a few times a second over long period, I wonder if SQL Server Compact Edition offers some mechanism to reduce disk access.
By example, can SQL Server compact edition wait let's say 5-10 "insert into" commands before actually write to the database located on the flash card ?.
Any ideas which could help me to reduce flash wear would be greatly appreciated !
Thanks
