I have the following in a CMDExec type SQL Job step (details changed):
D:\path\PSExec.exe \\servername -accepteula -u "domain\username" -p password D:\path\executable.exe
This works fine.
However, I have set up a proxy in SQL Server for the same user account - which the job is using, so you'd think I wouldn't need the -u and -p arguments.
But if I don't supply them I get the error:
Unhandled Exception: System.Data.SqlClient.SqlException: Login failed for user 'NT AUTHORITY\ANONYMOUS LOGON'.
which is from SQL Server, because the remote executable connects to SQL as the same user context.
Why doesn't this work, and can I make it work without including the credentials in the job detail? (or a batch file, or similar)
Thanks
P.S. The SQL Server connected to by the remote executable is the same one as the job is run in, if it helps!
The reason is because Kerberos is not running!
Thanks to Marc Jellinek on LinkedIn SQLDBA group :)

I have a MySQL database hosted on Digital Ocean Managed Database service. I lost my previous dev machine and did not push the Schema to git along with application files. I am desperate to get back the SQL Schema in my local machine for further Development but have so far been usuccessfull. I have tried so many commands from different suggestions but they all failed.
I connect to the DB via the MySQL Shell using the command:
mysql -u username -password-h example-test-do-user-7878789-0.b.db.ondigitalocean.com -P 25060 -D example_db
All queries are executed successfully via this shell method. When trying to Dump the Schema to my machine, I use the following command:
mysql -u username -p -h mysql-test-do-user-4915853-0.db.ondigitalocean.com -P 25060 your_database_name \> database_file_name.sql
But I get the error as follows: mysqldump: unknown variable 'set-gtid-purged=OFF'
if I remove that part and try again, I get the error:
mysqldump: Got error: 2003: "Can't connect to MySQL server on 'localhost' (10061 "Unknown error")" when trying to connect
which doesnt make sense to me. So, without further ranting; How to I achieve my intended result.
NOTE: I did try Mysql workbench, but it won't connect all together
I can appreciate trying to achieve what you want via mysql shell. I stumbled across the same problem and for quite some tie did not find the help i needed, then I tried doing it using mysql workbench. Try it and you will find that its easier than usin the command-line approach. MySQL Workbench has a good GUI based database miguration capability. You can migrate you Do Managed DB directly into you local mysql server or export a schema dump. If you decide to go wit this approach, just make sure you add your machine's IP as a trusted source, else you will not be able to connect.
I'm trying to login to my mysql user created by the MySQL installation in bash shell.
So the command I'm trying to do is:
sudo -i -u mysql
But, it does nothing (nothing printed out in the console, not connected to any user whatsoever, etc...).
EDIT: The return value of the command is 1 though.
Here is the mysql user line in the /etc/passwd file:
mysql:x:89:89::/var/lib/mysql:/bin/false
I'm running on ArchLinux 64bit and the user I'm trying to connect to is local (no connection to a remote server whatsoever).
I'm trying to understand why I can login with any other user (like postgres, root, ...) but not mysql.
Hope you can help!
This is intended behaviour. When you compare the /etc/passwd line with other lines you'll notice that the user mysql has /bin/false setup as the shell while others have usually /bin/sh or sth. similar.
When you sudo to mysql you actually get a login for about a millisecond or so and then his "shell" gets executed. /bin/false immediately returns with rc=1 (that's the only purpose of the false command).
This is some kind of "trick" to prevent users from logging in as user mysql although the account is otherwise fully operational.
The user mysql may even have a valid password and be enabled but due to his odd shell setting you cannot login as him. Sometimes these technical users have /usr/bin/passwd set as their shell. Then you can only sudo to that user and change his password, nothing else.
I have two mysql databases that I want to run a diff on, the user I want to connect with (root) has a password.
when I use the command given in mysqldiff documentation here:
mysqldiff --server1=root#localhost --server2=root#localhost --difftype=sql old_db:db_brand_new
I get an error saying that my command is unauthorized.
I have tried variations on the normal -p switch but it doesnt work.
How can I authenticate the mysqldiff command?
The documentation you linked says:
--server1=<source>
Connection information for the first server in the format: <user>[:<passwd>]#<host>[:<port>][:<socket>] or <login-path>[:<port>][:<socket>].
--server2=<source>
Connection information for the second server in the format: <user>[:<passwd>]#<host>[:<port>][:<socket>] or <login-path>[:<port>][:<socket>].
so you can try
mysqldiff --server1=root:[YOURPASSWORDHERE]#localhost --server2=root:[YOURPASSWORDHERE]#localhost --difftype=sql old_db:db_brand_new
I just installed SQL Server 2008, and I wanted to use the command editor to execute queries.
To do that I opened the command prompt, and I typed
Sqlcmd -S Serverinstance
but I got an error saying :
Named Pipes Provider: Could not open a connection to SQL Server [53].
Sqlcmd : erreur : Microsoft SQL Server Native Client 10.0 : A network-related or instance-specific error has occurred while establishing a connection to SQL Server. Server is not found or not accessible. Check if instance name is correct and if SQL Server is configured to allow remote connections. For more information see SQL Server Books Online..
Sqlcmd : erreur : Microsoft SQL Server Native Client 10.0 : Login timeout expired
What should I do to get it connected to the server so I can proceed?
Thank you :D.
(This one is going to sounds silly) my problem was that I wasn't using capital 'S'
Eg:
C:\> SQLCMD -S localhost\sqlexpress
You need to either use the integrated-security approach of using your Windows credentials to connect to SQL Server by specifying -E as an option:
C:\> SQLCMD -S Serverinstance -E
or then you need to define a user/password set to achieve a SQL Server login:
C:\> SQLCMD -S Serverinstance -U (login in) -P (password)
All the many SQLCMD parameters are well-documented on MSDN SQL Server Books Online!
The server you are specifying cannot be found or is not accessible. so either the server is wrong (have you spelt it correctly) or you are not specifying it correctly or it is not accessible from your machine.
After you've got that right, you will need to specify a username/password or a -E command qualifier for a Trusted Connection. You may also need to specify the database with a -d qualifier.
You can get help by typing
Sqlcmd -?
I am trying to learn PHP and MySQL and while I reached a chapter on MySQL I was asked to create a database using this command:
CREATE DATABASE publications;
After I typed it in the mysql console I got this error:
ERROR 1044(42000):Access denied for user ''#localhost' to database 'root'
I am already logged in to my administrator account so I think the privileges should't be a problem.I have installed with the XAMPP package.
How can this be solved?
It could be possible that you upgraded your version of EasyPHP or you did something to disable the root password. If that is the case, you should try reestablishing a password for root. Had the same problem and that's how I solved it.
Go to http://localhost/xampp/ and set the appropriate passwords (in Security tab). If you use mysql client program, make sure you call it with appropriate credentials: mysql -u <username> -p <password>. Username will mostly be root until you create some new accounts.
Then I suggest you use phpMyAdmin for experimenting with MySQL (it should be at http://localhost/phpmyadmin/ )
This is getting a little confused - let me try to answer this.
Mysqladmin is a command line client for administering your mysql database system - you normally don't need to run it once you have mysql working. The shell command line interface to the mysql server is mysql. (If you don't know how to run a shell command line, that's another problem. Also, if you're on Windows, say so, since that has its own challenges.) The arguments are:
mysql -u username -ppassword databasename
if you are running this command on the same server as mysql. Note the lack of space after the -p - that is important.
So, type the above line to invoke the command line interface to mysql. Then you can type your mysql commands. Things like show tables, desc tablename, etc., will work. That is they will work unless you have an authentication problem. But you will know you have an authentication problem because when you tried to run mysql as above, it will fail with some error, like "Access denied for user 'abc'#'localhost' (using password: YES)". This is a nice descriptive error message that points you exactly where the problem is.
Does that help?
You can go back to using xampp or anything else once you've made sure that you know the right parameters by checking with the command line. (Always check with the command line when strangeness happens - it's so much easier than trying to debug through other interfaces.)
