I have a developer pc "A". And I have a SQL Server "B".
My SQL Server is a Microsoft SQL Server 2019.
On server B, I have a database with a stored procedure, which bulk loads data from a text file (using the BULK INSERT command).
I have now created an SSIS project on server A, which calls the stored procedure on server B using the "Execute SQL Task". The connection on the task is pointing at the database on server B. I have tried using the OLE DB connection and ADO.
When I place my text file on server B and reference the file like D:\myFolder\myFile.txt, everything works fine.
When I place my text file on server A and references the file like \\\A\myShare\myFile.txt it fails. The error I get is:
[Execute SQL Task] Error: Executing the query "exec BulkInsert
'\\A\myShare\myFile.txt'" failed with the following error: "Cannot
bulk load because the file "\\A\myShare\myFile.txt" could not be
opened. Operating system error code 5(Access is denied.).". Possible
failure reasons: Problems with the query, "ResultSet" property not set
correctly, parameters not set correctly, or connection not established
correctly.
I have tried logging on to server B and via a File Explorer open the file using the above path. It works fine. And yes, I am logged in as the same user on both servers A and B.
I have also tried giving "Everyone" read/write access to the share, but still the same poor result.
I am only interested in knowing how to fix this problem, using the stored procedure call - I do not wish to rebuild its functionality in SSIS (the stored procedure is maintained by an external company and they may change it at their will, but we agree on how I can call it).
According to what I read from Microsoft, it should not be a problem, call BULK INSERT using a UNC path.
According to what I read from Microsoft, it should not be a problem, call BULK INSERT using a UNC path.
This is true, UNC paths are supported by the BULK INSERT command.
Based on the Microsoft documentation, BULK INSERT has three main requirements:
The server must have permission to access both the file and the destination database.
The server runs the Bulk Insert task. Therefore, any format file that the task uses must be located on the server.
The source file that the Bulk Insert task loads can be on the same server as the SQL Server database into which data is inserted, or on a remote server. If the file is on a remote server, you must specify the file name using the Universal Naming Convention (UNC) name in the path.
The first requirement means that you should grant the SQL Server Service account to access the UNC path, not the Windows account you are logging in with.
You should refer to the following articles to find the SQL Server service account name:
Configure File System Permissions for Database Engine Access
How to Find Service Account for SQL Server and SQL Server Agent?
Besides, you can learn more about SQL Server service accounts and permissions in the following documentation:
Configure Windows Service Accounts and Permissions
Alternative - Mapping network drive
As an alternative, you can try mapping the network drive within SQL Server. You can check the following articles for more information:
Make Network Path Visible For SQL Server Backup and Restore in SSMS
How to Map Network Drive as Fixed Drive?
I am currently trying to take backup of a database to a network UNC share, but its giving me error.
I have two PCs connected in a simple NETWORK, not a domain.
From both pcs, I can easily create and edit files on either one.
One PC on which SQL SERVER is running and database files are located, is named SERVER.
Another PC on which I want to take backup, is named STUDENT-PC2. On this pc, drive d: is a shared drive and I set the full permission for this folder for Everyone, IUSER,NETWORK,NETWORK SERVICE
When I run following command from SQL SERVER MANAGEMENT STUDIO on SERVER, it throws me error as below.
I am running sql server service as NETWORK SERVICE
COMMAND
backup database dpmt to disk='\\STUDENT-PC2\d\DPMT_BACKUP_17032016_102719.Bak'
ERROR
Msg 3201, Level 16, State 1, Line 1
Cannot open backup device '\\STUDENT-PC2\d\DPMT_BACKUP_17032016_102719.Bak'. Operating system error 5(Access is denied.).
Msg 3013, Level 16, State 1, Line 1
BACKUP DATABASE is terminating abnormally.
On computer "STUDENT-PC2" locate the file share that is destination for backups. In file share permissions add account named as your SQL machine plus dollar sign, like this: "SERVER$" - type that instead of username. Tick write+read permissions for that artificial "user", and hit OK to close. On the file system level configure permissions the same (write+read) or let Everyone write at first to test and then reduce.
In summary:
if both computers are not part of the same domain, the other computer (STUDENT-PC2) sees all local accounts from "SERVER" as "SERVER$" account, no matter what they real name is.
you need to set permissions on destination (STUDENT-PC2) for account "SERVER$" at two levels: file share permission level, and ntfs file system permission level.
I am starting to learn SQL and I have a book that provides a database to work on. These files below are in the directory but the problem is that when I run the query, it gives me this error:
Msg 5120, Level 16, State 101, Line 1 Unable to open the physical file
"C:\Murach\SQL Server 2008\Databases\AP.mdf". Operating system error
5: "5(Access is denied.)".

ON PRIMARY (FILENAME = 'C:\Murach\SQL Server 2008\Databases\AP.mdf')
LOG ON (FILENAME = 'C:\Murach\SQL Server 2008\Databases\AP_log.ldf')
FOR ATTACH
GO
In the book the author says it should work, but it is not working in my case. I searched but I do not know exactly what the problem is, so I posted this question.
SQL Server database engine service account must have permissions to read/write in the new folder.
Check out this
To fix, I did the following:
Added the Administrators Group to the file security permissions with
full control for the Data file (S:) and the Log File (T:).
Attached the database and it works fine.
An old post, but here is a step by step that worked for SQL Server 2014 running under windows 7:
Control Panel ->
System and Security ->
Administrative Tools ->
Services ->
Double Click SQL Server (SQLEXPRESS) -> right click, Properties
Select Log On Tab
Select "Local System Account" (the default was some obtuse Windows System account)
-> OK
right click, Stop
right click, Start
Voilá !
I think setting the logon account may have been an option in the installation, but if so it was not the default, and was easy to miss if you were not already aware of this issue.
To get around the access denied issue, I started SSMS as administrator and that allowed me to attach a database from my local drive. The database was created in another SQL and windows instance.
This is Windows related issue where SQL Server does not have the appropriate permission to the folder that contains .bak file and hence this error.
The easiest work around is to copy your .bak file to default SQL backup location which has all the necessary permissions. You do not need to fiddle with anything else. In SQL SERVER 2012, this location is
D:\Program Files\Microsoft SQL Server\MSSQL11.MSSQLSERVER\MSSQL\Backup (SQL 2012)
C:\Program Files\Microsoft SQL Server\MSSQL12.MSSQLSERVER\MSSQL\Backup (SQL 2014)
C:\Program Files\Microsoft SQL Server\MSSQL13.SQLEXPRESS\MSSQL\Backup (SQL 2016)
I had this problem. Just run SQL Server as administrator
Yes,It's right.The first you should find out your service account of sqlserver,you can see it in Task Manager when you press ctrl+alt+delete at the same time;Then,you must give the read/write privilege of "C:\Murach\SQL Server 2008\Databases" to the service account.
I solve this problem by adding Full control permission for both .mdf and .ldf files for Users group.
The problem is due to lack of permissions for SQL Server to access the mdf & ldf files. All these procedures will work :
you can directly change the MSSQLSERVER service startup user account, with the user account who have better privileges on the files. Then try to attach the database.
Or you can assign the user to the file in security tab of the mdf & ldf files properties with read and and write privileges checked.
Startup with windows administrator account, and open SQL Server with run as administrator option and try to login with windows authentication and now try to attach the database.
For me it was solved in the following way with SQL Server Management studio
-Log in as admin (I logged in as windows authentication)
-Attach the mdf file (right click Database | attach | Add )
-Log out as admin
-Log in as normal user
The actual server permissions will not matter at this point; all looks ok.
SQL Server itself needs folder permissions.
depending on your version, you can add SERVERNAME$MSSQLSERVER permissions to touch your folder. Othewise, it has to be in the default BACKUP directory (either where you installed it or default to c:\programfiles(x)\MSSQL\BACKUP.
Even if you do the following steps you COULD get the same error message.
1. login as SA user (SSMS)
2. Edit the file permissions to say "everyone" full access (windows folder)
3. Delete the Log file (Windows Exploring (this was what I had done per advise from some msdn forum)
I still GOT the permission error, but then I noticed that in the Attach screen, the bottom section STILL showed the LOG file, and the error message remained the same.
Hope this helps someone who did the same thing.
It means the SSMS login user does not have permission on the .mdf file. This is how it has worked for me:
I had opened the SSMS (Run as administrator) and login as an administrator user, database right-click attach, click add, select the .mdf file, click Ok. Done.
I had this issue when I try to backup a database.
System.Data.SqlClient.SqlError:
Cannot open backup device 'C:\x\x\xxx.bak'.
Operating system error 5 (Access is denied.). (Microsoft.SqlServer.Smo)
When I had this issue I thought that the user which I'm connecting to database don't have rights to access to the backup location. I gave full control to that user but nothing changed. This is because the service for SQL Server is running with another user.
At this point you may choose changing user of the service to local system account or add access rights for the current user of the service.
I choose the 2nd one.
After that change backup succeeded.
Very Simple Solution.
Login with System admin
copy your mdf and ldf files in "C:\Program Files (x86)\Microsoft SQL Server\MSSQL11.MSSQLSERVER\MSSQL\DATA" Where all other data file recides.
Now attach from there it will work
I used Entity framework in my application and had this problem,I seted any permission in folders and windows services and not work,
after that I start my application as administrator (right click in exe file and select "run as admin") and that works fine.
If you get this error on an .MDF file in the APP_DATA folder (or where ever you put it) for a Visual Studio project, the way I did it was to simply copy permissions from the existing DATA folder here (I'm using SQL Express 2014 to support an older app):
C:\Program Files\Microsoft SQL Server\MSSQL12.SQLEXPRESS2014\MSSQL\DATA
(note: your actual install path my vary - especially if your instance name is different)
Double click on theDATA folder first as administrator to make sure you have access, then open the properties on the folder and mimic the same for the APP_DATA folder. In my case the missing user was MSSQL$SQLEXPRESS2014 (because I named the instance SQLEXPRESS2014 - yours may be different). That also happens to be the SQL Server service username.
For some reason, setting all the correct permissions did not help in my case. I had a file db.bak that I was not able to restore due to the 5(Access is denied.) error. The file was placed in the same folder as several other backup files and all the permissions were identical to other files. I was able to restore all the other files except this db.bak file. I even tried to change the SQL Server service log on user — still the same result. I've tried copying the file with no effect.
Then I attempted to just create an identical file by executing
type db.bak > db2.bak
instead of copying the file. And voila it worked! db2.bak restored successfully.
I suspect that some other problems with reading the backup file may be erroniously reported as 5(Access is denied.) by MS SQL.
In linux, I went to /var/opt/mssql/data/ folder and opened a terminal with sudo then, changed my *.mdf and *.ldf file permissions as below in which you replace yourDB with your Database file name and myUser to currently logged username:
chmod 755 yourDB.mdf
chown myUser yourDB.mdf
chmod 755 yourDB.ldf
chown myUser yourDB.ldf
After that, it was reconnected without any issue.
If the database you are trying to attach is compressed it may show error message.
First you have to decompress the file. For that go to properties of mdf/ldf file >> then "Advanced" >> Uncheck "Compress Contents to save disk space" >> Press "Apply".
After that give it a try.
Run SQL Server management studio as Administrator
Log in as Windows user
Remove log file if you have only MDF file (haven't log file)
With 3 items in the above checklist, you will remove almost problems related with attach database task.
If you're using Storage Gateway - SMB (S3)
Do this from the management studio
EXEC xp_cmdshell 'net use X: \100.155.16.6\mystoragegatewayfolder xxmysuperpassxx /user:sgw-445577\smbguest /persistent:yes /y'
EXEC XP_CMDSHELL 'Dir X:' (this should show you the Directory info, serial no etc)
Mount the drive (This PC - > Mount network drive, using the same info above)
Test run a backup job using scheduled backup, this will force to use the sql server agent and you can see where it's writing and whats the issue if any.
I tried to detach my SQL Server 2008 R2 database for creating a duplicate of it, meanwhile connections to that database were active from Visual Studio (2010). So SQL Server denied to detach. After closing Visual Studio, I tried again and my database was successfully detached.
After detaching my database I tried to copy both files (.mdf and .ldf) to another folder as a duplicate copy, but I could not do so because I was getting error that says
You require permission from the computer administrator to make changes to this file
I am using Windows 7 and my account is Administrator. I also tried to attach my database again to SQL Server (running it with administrator permission) but I got the following error:
Failed to retrieve data for this request. (Microsoft.SqlServer.Management.Sdk.Sfc)
Additional Information:
An exception occurred while executing a Transact-Sql statement or batch.
(Microsoft.SqlServer.ConnectionInfo)
CREATE FILE encountered operating system error 5 (Access is denied,) while attempting to open or create the phyical file'C:/Mywor/MyDataBase.mdf'.
(Microsoft SQL Server, Error: 5123)
Please help me if someone know how to handle this problem.
Here are couple things you can try:
Stop SQL Server service and see if you can copy files (to stop SQL service go to SQL Server Configuration manager)
Try to copy some other database files in that directory and see if that works (make sure permissions for both files are exactly the same)
Try to copy .mdf and .ldf files in original SQL Server data directory (you can find it in SSMS -> Instance properties ->Database Settings
If you’re not using windows explorer for copying files make sure you run it as admin (right click -> Run as administrator)
This is a permissions issue on the database files directory, or the files themselves. Just because you're logged on as an administrator doesn't mean that Windows 7 allows you to do anything you want without whinging at you first. Also, the SQL Server service account may not have the appropriate permissions on the file/folder.
When I type this:
CREATE DATABASE AdventureWorks2012
ON (FILENAME = 'C:\Users\sohm\Desktop\Pohm\AdventureWorks2012_Data.mdf')
FOR ATTACH_REBUILD_LOG ;
I get this:
File activation failure. The physical file name
"C:\Users\sohm\Desktop\AdventureWorks2012_Data_log.ldf" may be incorrect.
Msg 5123, Level 16, State 1, Line 1
CREATE FILE encountered operating system error 5 (Access is denied.) while attempting to
open or create the physical file 'C:\adventuredb\AdventureWorks2012_Data_log.ldf'.
Msg 1813, Level 16, State 2, Line 1
Could not open new database 'AdventureWorks2012'. CREATE DATABASE is aborted.
I know it has to do with permissions. I have the administrator account. I have read a million posts but nothing has worked so far. Also when I try to change the folder containing the mdf file, to full control but it keeps reverting back to read-only.
You should run SSMS as an administrator.
Also it is possible that you might be running query as an 'sa' user(sql server authentication).
Try running the query with windows Authentication.
SHORT VERSION
For allowing MS SQL server 2012 to attach the database files you must grant full access to the mdf and ldf files to:
NT Service\MSSQLSERVER
Full Access
LONG VERSION
SQL Security has been updated a lot in 2012 handling of files.
http://technet.microsoft.com/en-us/library/ms189128.aspx
If you look at the existing attached databases and there security you will probably see that there only are 2 roles allowed with full access. MSSQLSERVER and Administrators, when attached SQL Removes all other roles from the files.
Trying to set the MSSQLSERVER from the fil security Permission will not work.
Looking at your services.msc overview you will in a default install see that NT Service\MSSQLSERVER also runs the SQL server servics.
The service account is not visible, the same issue as with IIS AppPools, a sub group has been created by the system and "hides" the accounts from auto discovery, probably to try and secure the accounts but in my view just obscures the setup.

Open the SQL Server Management Stdio in Administrator mode(Right click -> Select Run as Administrator. If it asks for User name and password enter your Administrator user name password). Then select Windows Authentication click ok, and now try to attache it will attache without any error.
This has nothing to do with YOUR account. SQL Server is trying to write to that folder under the context of the service account that is running SQL Server. You can see who this is by going to the Services applet and seeing who the instance runs as (probably NT AUTHORITY\SYSTEM or whatever). You can override that or you can place your MDF files in the data folder, which SQL Server already has inherent access to, instead of placing them in this other location on your C:\ drive.
Another way to solve this is to change all the SQL Server services to Local System Account instead of services. Start -> Run ->Services.msc -> Scroll down to SQL Server, you should see five services that start with SQL Server. Right-Click, Properties, Log On, change to Local System Account. Repeat for all the rest of the SQL Server Services and restart them all.
Try This
Go to the folder where you have stored mdf file.
Select file -> Right click -> click on mdf give full permissions to file for logged in user Security.
If still issue persist and it might me because of corrupted transaction logs, you may use tool SQL Database Recovery Tool Repairs to repair your corrupted mdf file.
Figured it out. I went to sql server configuration manager and right clicked SQL Server Service. Then I added my Windows Admin account to run the service and now it works.
