I'm trying to set up SSH tunneling on a remote web server to another MySQL server so that the database can be browsed easily with MySQL Query Browser. I'm following this page but cannot connect to the MySQL server. -your-mysql-server-remotely-over-ssh/
Well, the workstation running 12.04 on which I found mysql-query-browser, was updated from 10.04 to 12.04 - it was retained across the upgrade - so that is a different situation than a non-upgrade clean install of 12.04 .
If you think as many others that unfortunately mysql-workbench is not a good and a simple tool to do quick and fine things, you can install previous deleted tools directly from the repository manually. You just have to download and install the following .deb packages:
-gui-tools-common/5.0r14+openSUSE-2.2ubuntu2 -1ubuntu5 launchpad.net/ubuntu/precise/amd64/mysql-query-browser/5.0r14+openSUSE-2.2ubuntu2 launchpad.net/ubuntu/precise/amd64/mysql-admin/5.0r14+openSUSE-2.2ubuntu2
I use mysql administrator to manage my mysql databases. I CAN run the administrator but when I wan't to change some stuff in the database and start mysql query browser it fails to start with the error:
Googling the error shows this is a classic unavailable connection problem and lots of links show fixes for the server, but the problem seems to reside entirely in the install of the query browser, which doesn't make any sense. Thus Google is no help.

The main Query Browser window has three important areas. Along the top is the text area where you can build and execute SQL queries. Below this is the results area. You can use manage multiple result sets at once using tabs and even split a tab so you can compare two sets. To the right of the results area is a list of databases and their tables. These allow you to quickly switch between databases and view or edit tables. Although you can do everything manually via SQL query, the Query Browser has decent GUI tools to create and edit table structures, which can often save time and stress over a misplaced quotation mark. It also comes with built-in documentation, allowing you to recall query syntax at the click of a button.
The Windows version of the GUI tools are supplied as an installer executable. To perform the installation, simply launch the installer once the download is complete.The Linux version of the tools can be installed using RPM (note that the filenames may change for later releases or different Linux versions of the software):su -rpm -ihv mysql-gui-tools-5.0r12-1rhel4.i386.rpmrpm -ihv mysql-query-browser-5.0r12-1rhel4.i386.rpmOn Windows, the MySQL Query Browser can be launched from the Desktop Start menu. On Linux, the tool is launched as follows:mysql-query-browserConnecting the MySQL Query Browser to a Database ServerWhen the MySQL Query Browser tool starts the following login screen will appear:
Enter the name of the host on which the database server resides, together with appropriate user and password credentials. Finally, specify the name of database in the Default Schema field on which you wish to work during the Query Browser session (note that you can switch to a different database later from within the tool). Click on the Connect button to connect to the specified server.
The large gray area in the center of the screen displays the results of the executed statements. An additional section at the bottom of the window appears to display any errors encountered as a result of a SQL statement. Additional Resultset pages may be added from the File->New Query Tab menu option.In the top right hand side of the window is a list of databases available on the server to which the tool is currently connected. Clicking the arrow next to any database will display the tables contained therein. Clicking on the arrow next to a table will similarly list the columns in that table. Right clicking with the mouse in this area pops up a menu providing options to create new tables, views and databases. This menu also provides an option to select a different schema to the one chosen at the login screen and provides the option to drop the currently highlight table or database.The bottom right side of the main window provides a list of help topics. Double clicking on a list item will display help text in the result area of the screen. To return to the results page, either close the SQL Help tab, or click on the Resultset tab.Executing SQL StatementsTo execute a SQL statement in the MySQL Query Browser, simply type the command into the text field at the top of the main screen. The text input field is free format, allowing you to press enter in order to spread a statement over multiple lines. As with all SQL statements, the completed statement must be terminated with a semi-colon (;). Pressing the execute button will cause the statement to be executed and the output to be displayed in the results area. The following figure shows the result of running a SHOW DATABASES; command:SummaryThe MySQL Query Browser provides a user friendly environment in which to execute SQL statements. This is a useful learning tool for the beginner and provides an alternative to the mysql tool.
I basically have a php script connecting to a pdo:mysql database which executes some time-consuming loop.
All works fine, unless the query is still running on the server side, updating infinitly, even after browser closed. I have to kill the mysql proccess (sleep) to stop it.
In corporate world where employees work from different locations, managing databases via browser make things pretty easy. And, most database providers give access to databases from specific IP address.
Fortunately, there are many options like PHPMyAdmin, DbAdmin, HeidiMySQL, etc. that make databases accessible via browser. These interfaces help users to connect to the database servers using login details. But, for this to work, the MySQL server should accept connections from the user IP address.
Now, its time to see the causes for MySQL query browser error 2003. From the vast experience in managing servers, our Dedicated Engineers typically see MySQL connectivity errors due to following 3 major reasons. They are:

To create a view from a query, you must have executed the query successfully. To be more precise, the view is created from the latest successfully executed query, not necessarily from the query currently in the Query Area. To further clarify, the following three examples are cases where the view is not created from the current query:
I have been writting an EJB3 prototype using MySQL 4.1.xx, and I was getting a SQL parse error on the generated insert statement, causing my Order object's persist to fail. After experimenting using the MySQL query browser, I discovered that MySQL requires the catalog or schema name to be prepended to the table name even though you have connected specifically to that catalog in the connection URL. Therefore the following Hibernate (EJB3) generated SQL statement of:
insert into Order (state, customerid, addressline1, addressline2, city, zipcode, zipplusfour) values (?, ?, ?, ?, ?, ?, ?)
fails, and it needs to look like this:
insert into prototype.Order (state, customerid, addressline1, addressline2, city, zipcode, zipplusfour) values (?, ?, ?, ?, ?, ?, ?)
Now, the only way I could get the statement to look like this was to change the entities @Table tag from:
@Table(name="Order)
to:
@Table(name="prototype.Order")
Obviously, this ties the entity directly to the specific schema, making it un-portable to multiple database schema's or catalogs. This cannot be the proper way to fix this issue, even though it did work.
Can anyone shed some light on what I am missing? There must be a property somewhere that I am not setting or not setting correctly.
Hi, today we had a user create a poorly written query which bogged down our MySQL server. We noticed that CPU usage spiked to 50% and stayed there until the query was killed. Our server has a quad core processor.
