I was using navicat for mysql to connect to mysql 5.5.25,it usually show me this:2005 - Unknown MySQL server host 'localhost'(0).Currently my resolution is to turn up the network,then it return to normal.but when network is not up,it shows that error,I had searched a lot,but no answer is revalent to it.So,does anyone knows the reason?
I had the same problem, but it only occurs when my computer is not on-line (for example when working on an airplane). I just change the word 'localhost' to 127.0.0.1 and it seems to be working even when off-line. I hope.
if you try to create the linked server using studio and the various menus, a small detail is not saved in the connection string, which is the database! (see last bit of the connection string)
EXEC master.dbo.sp_addlinkedserver #server='MYSQL',
#srvproduct='MySQL',
#provider='MSDASQL', #provstr='DRIVER={MySQL ODBC 5.1
Driver};SERVER=HOST;Port=3306;USER=uid;PASSWORD=pw;OPTION=3;DATABASE=mydb';

My workbench was previously working fine until recently, but I'm now getting the following error:
I'm not sure what's relevant so I'll list out everything that I think might be relevant:
My OS is Windows and I'm using JawsDB & Heroku as my server.
I've recently tried to mess with the my.cnf file (in an attempt to enable 'LOAD DATA LOCAL INFILE')
I think this is the extent to which I've used mysql_config_editor:
I've run "SET GLOBAL local_infile = true;" after logging in to my local sql.
I've checked numbers 1-4 on the error message. Here is an image of my connection to be sure:
I think I've messed with the NetBIOS at some point, and that might be a problem as discussed here, but I don't see "manage server instances" anywhere.
I'm not sure what else might be the issue here. Thanks in advance.
Edit: After trying to connect to the MySQL server through the command line, I get "ERROR 2003 (HY000): Can't connect to MySQL server on 'lyl3nln24eqcxxot.cbetxkdyhwsb.us-east-1.rds.amazonaws.com' (10060)", which seems to be an authentication error and not a connection error according to this link. But I'm unsure how to deal with this authentication error if it is one.
I'm not sure if this constitutes as an answer, but I've managed to establish a connection through my usual wifi (as opposed to a public school's wifi). It looks like either my security settings are different when on a public wifi or the public wifi itself had some sort of security setting that was blocking my connection.
I've got WampServer running a local instance of WordPress, and I have SSRS running in native mode.
I've written a report that queries the MySQL database, and it works and runs just fine within Visual Studio.
If I launch it though, it first had issues with my ODBC shared data source, which was as follows:
Name of shared data source: localhost.rds
ODBC Connection string: Dsn=localhostuserDSN
That DSN is a user DSN (as you might've guessed), and it uses the MySQL ODBC 5.3 Unicode driver. It's configured as follows:
TCP/IP server: localhost
Port: 3306
User: root
Password: <blank>
Database: wp
When tested, the connection succeeds, and the report works just fine.
When deployed though, I got the following error:
ERROR [IM002] [Microsoft][ODBC Driver Manager] Data source name not found and no default driver specified
After much research and hair-pulling, I finally found out that if I changed the data source connection string to...
Dsn=localhostUserDSN;Driver=MySQL ODBC 5.3 Unicode Driver
...that also works, and at least then, the connection also succeed when in the Data Sources configuration screen for the report after it's deployed. But then, just when I thought I was finally out of the woods, I run the report and get the following error message:
ERROR [3D000] [MySQL][ODBC 5.3(w) Driver][mysqld-5.7.9]No database selected
The thing is, I can't specify a database, or at least I don't know a way to.
If I try changing the connection string to...
Dsn=localhostUserDSN;Driver=MySQL ODBC 5.3 Unicode Driver;database=wp
...it says the (blank) password isn't valid, before I've even pressed the 'Test' button.
If I tack on 'USE [wp]' to the query in Visual Studio, it abruptly protests.
I thought maybe I'd get around that by putting it in a stored procedure, but since the data is being queried directly from the MySQL database, I can't do that either.
(Before attempting any of this, I already tried syncing/converting the MySQL db to the SQL db, but I kept running into issues with the data conversion.)
Thinking it might be a permission issue, I've also tried running...
GRANT ALL ON [wp] TO root#localhost;
...and...
GRANT ALL PRIVILEGES ON [wp] TO root#localhost;
in SSMS, but in both cases, it says:
Cannot find the object 'wp', because it does not exist or you do not have permission.
And I'm the only admin on a local machine. I installed SQL and it uses Windows Authentication, so I don't see how I wouldn't have permission, and I have to assume it's an issue with the syntax.
I saw elsewhere here that someone suggested '[wp].*', but it doesn't like that either.
I've been at this literally all day, and I'm at my whits end, so any constructive feedback would be greatly appreciated!
For anyone stumbling across this in the future, I think we resolved the original issue, although I've run into other issues which may be specific to me.
Three things, not sure if the first one is related:
1) In the query for the dataset of the report, I specified the table like so "SELECT wp_posts.ID FROM wp_posts" instead of just "SELECT ID FROM wp_posts".
2) I went back to adding on "database=wp" to the ODBC connection string.
3) Even though both work in Visual Studio, I switched to a System DSN instead of the User DSN.
I think that should get you back in action.
I am trying to connect Power Bi (Desktop version) with my online amazon mysql database. It demands for following information once you try to establish connection
Server: server ip
Database: database name
Username: mysql username
Password: mysql password
First time I received a bit lengthy error, which was because of unavailability of mysql-connector-net-6.6.5.msi. So I followed this link to solve the issue
Microsoft Power BI connect to mysql
After installing mysql-connector I am facing another error.
Whats wrong? One of my mates has successfully connected using the same credentials that I am using.
Okay, I just figured this out for myself. I'm able to connect directly to a MySQL database on port 3306. As I understand, it would be more secure to go through an SSH tunnel, but this doesn't work yet with Power BI.
So here are instructions for connecting directly:
First, let's make sure that everything besides the PowerBI connection is working.
1) Download and install the correct version of the MySQL/Net Connector. Right now, version 6.6.5 is the one that works. But from other forums, and from within PowerBI itself, I linked to other versions that did not work. (You will know it isn't working, because you probably won't be able to even open Get Data/MySQL Database/Connect.)
2) See if you can connect remotely to your database through some well established utility like MySQL workbench. If you can't,
- look at ports on the remote server. Here's a cool utility to check ports&IPs: http://www.yougetsignal.com/tools/open-ports/
- Check the permissions of the DB user. Realize that they may be affiliated with an IP address: 'username'#'ipaddress'. So that user can only connect for a particular IP.
- Check the bind address setting. In newer versions of mariadb, it should probably be commented out. I'm not sure about older version and pure mysql.
- other troubleshooting.
So after that's working, here are the settings which worked for me in MySQL:
go to Get Data/MySQL database/connect
Server: ipaddress:3306 (include ":port#")
Database: dbname
PowerBI interface. Select "Database" instead of "Windows"
Make sure you select Database instead of Windows.
Good luck.
Just a small tip. If you haven't already, restart the machine you just installed the connector on. I had to restart before it started working.
My solution for this was to add the port number to the server name/ip
eg. 192.168.0.1:4664
Long time lurker, first time poster; hoping anyone can help me out.
Im using MySQL Workbench 5.2.41 to migrate a database from SQL Server to MySQL 5.0.8
The entire process goes smoothly: both SQL and MySQL connection Tests are good, the skemea and table create as expected, everything checks out until the 'Bulk Data Transfer' step. At that point I receive this error:
...
Migrating data...
wbcopytables.exe --odbc-source=DSN=SQL Server 11;DATABASE=;UID=sa --target=root#127.0.0.1:3306 --progress --passwords-from-stdin --thread-count=1 --table [GSAClosers_v2] [dbo].[AccountBase] `dbo` `AccountBase`
`dbo`.`AccountBase`:Copying 84 columns of 169530 rows from table [GSAClosers_v2].[dbo].[AccountBase]
ERROR: `dbo`.`AccountBase`:SQLGetData: HY009:10:[Microsoft][ODBC Driver Manager] Invalid argument value `dbo`.`AccountBase`:
Finished copying 0 rows in 0m00s
Copy helper has finished
...
For connectors I'm using Microsoft SQL Server / ODBC Data Source / DSN: SQL Server and for MySQL the IP and port(3306).
SQL Server 2012 Management Studio connects and all operations work as expected.
O, side not: both are on the same localhost machine.
If anyone can shed some light on this I would be forever indebted. Thanks in advance
From here:
[Microsoft][ODBC Driver Manager] Invalid argument value.
Regarding to the error message and code you provided, which seems is
database is invalid or cannot be accessed. That means either the
database does not exist or the user does not have permission to access
the database.
It turns out you need specify the instance after the server name, so
in the server name in the dialog box for creating the ODBC Data
Source, you must enter it as either: MyServer\SQLEXPRESS or
.\SQLEXPRESS
I think you may have a problem connecting to your database from wbcopytables.exe. Keep in mind that this is a separate tool so the fact that you can connect from the rest of the Migration Wizard doesn't imply that you will connect in wbcopytables.exe.
The thing that worries me the most is that your DSN has whitespace characters. This might be interpreted by the Windows terminal as independent command line parameters. One thing you can do is to edit your DSN name removing the whitespaces and try again.
You may also want to connect without a DSN by putting all your connection parameters explicitely as explained in my blog post: How-To: Guide to Database Migration from Microsoft SQL Server using MySQL Workbench.
And, by the way, since MySQL Workbench 5.2.42 is out you should go and get it. The Migration Wizard is pretty new so important bug fixes are likely launched in each recent Workbench release.
In either case I think you should file a bug with your issues with a detailed explanation about how to reproduce it, possible solutions, etc.
Hope this helps.
Ok, got it figured out: un-install java. install java 1.6, use MySQL Migration Tool. change all data types to varchar, ints and bits. run migrations....eat data.
I'm running into a little trouble with MySQL Workbench.
This is the situation, I'm developing a database to query it remotely from Android devices. This is the first time I use MySQL Workbench, so I've followed this tutorial:
http://net.tutsplus.com/tutorials/databases/visual-database-creation-with-mysql-workbench/
I have no problem creating the EER diagram and generating the SQL script. The problem comes when I try to connect to a MySQL server. I get this error:
"Failed to Connect to MySQL at 127.0.0.1:3306 with user root. Lost connection to MySQL server at 'reading initial communication packet', system error: 61"
http://img101.imageshack.us/i/capturadepantalla201104i.png/ (if the link stops working tell me)
I've also tried using the Local Socket/Pipe connection method with the MAMP Socket in '/Applications/MAMP/tmp/mysql/mysql.sock', but it gives the same error. And I've also tried using MAMP port 8889 but still nothing.
So anyone knows how to fix it? And another question, can I connect from my Android device to my laptop(where the database is placed) without using MAMP? MySQL needs MAMP to serve queries? And the last thing, am I going into the right way? Or should I do it other way?
Thanks for reading.
I had the same issue, but part of your question is what fixed it for me:
Set connection = Local Socket/Pipe
Set socket path = "/Applications/MAMP/tmp/mysql/mysql.sock" (for me - I got the path from my MySQL log upon initialisation)
Running: MBP, OSX 10.8.3 (Mountain Lion), MAMP Pro
Can't really fathom any further what your issue may be, but perhaps double check your DB is properly initialised. But, perhaps this helps someone else :)
I typed: sudo /usr/local/mysql/support-files/mysql.server start
into the terminal and it started the MySQL server successfully and I was able to connect to MYSQL workbench.
You need to sure that Mysql process is running in your system. not sure in MAC but in windows it'called mysqld.exe
well take a look
http://lists.mysql.com/mysql/124371
Most commonly happens when database/server is not running. You need to check your server, or restart it. You can do so if you have mysql workbench under server administration. Check your manual for restarting or starting the server.
On osx 10.6 using mamp pro I solved this by allowing network access in the MySQL tab from the home window. Hope it saves someone the pain too
When trying to use the MySQL Workbench and connect through an SSH tunnel, you will get this error when your SSH connection does not complete successfully (e.g. improper host, password, key file, etc)
A good way to trouble shoot this is to separately test the the ssh connection from the machine you are trying to connect from and establish that you can do so successfully.
Try closing MySQL and running it as the admin. This worked for me.
After making above improvement such as checking if mysql service is running or not, you just need to give a small password while creating connection, it is ' ' or 1 time press on space-bar in case of GUI or workbench.
After which you just need to validate your machine with server (validated HOST).
For that purpose click on 'New Server Instance' and it will configure server/HOST on your behalf itself.
I have done this successfully just a few couple of minutes ago. My workbench software is able to show all pre-installed databases etc now.
Thanks!!!
I solved it! On a mac just go to spotlight search on the top right of the screen and type Mysql. Turn it on.
