Hi! I am trying to use the Database Query Browser connected to a MYSQL database. As you can see in the screenshot, I can return table information from the MYSQL database but the schema is not populating in the right hand pane. Any advice on how to get the tables in the "Sakila" instance of the MYSQL database to show up in the Schema browser?

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
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.
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:
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.
MySQL client tools' settings are stored in a file called mysqlx_user_connections.xml. You just have to copy this file from one machine to another. Location of this file depends upon the operating system you are using.
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:

Of course, no browser-like interface can be complete without the wonders of tabs. You can create new Result Area tabs with Ctrl-T, or choosing New Tab and Execute from the options next to the Execute button. You can also split a tab with the Split Tab and Execute option. If a result set is too large, F12 will maximize the display area.
I tested MyQB with MySQL 4.1, but if you are using MySQL 5.0, you can also use it to create views. How? As simple as entering and executing the query that defines the view, and then pressing the Create View button.
None of the above is particularly exciting or useful, but one area that is, is the Information Browser. It is effectively your reference manual. Not sure how to use the HANDLER statement? You can skim through a paper book, rush off to mysql.com and start searching, or, easiest of all, click on HANDLER in the Information Browser (it is the third Data Manipulation statement under Syntax). There is also a function reference (see screenshot), a list of parameters, and a list of all queries in your transactions.
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.
They were referring really to the query, after all, the report is just a nicer interface to the results of the query, and actually we had people already creating horrible reports that queried the same table several times inside the same report taking 45 minutes to run.
This page will explain how to use MySQL in batch mode. This means executing SQL commands that are contained in a text file, a script. We also describe how to load data from a comma-separated file using the LOAD command. The examples here are all standard MySQL, so they should run at the mysql prompt on any platform, or in the MySQL Query Browser you can install. At the end of this page I've appended a text version of the relevant sections from the MySQL Reference Manual. I have not included a lengthy discussion of the LOAD command. Instead, I'll just give examples of its use in simple situations. Scripts are used a lot and are handy for repetitive tasks, debugging (just edit the script). LOAD is only used in loading a table with data from an external file, typically only when setting up the database. In fact, LOAD in fact, could be called from within a script. The examples below are all based on the CAP database, the primary example used in the O'Neils' textbook. All the examples are called "queries", that is, they are all SQL commands sent at the mysql prompt (or from the MySQL Query Browser).
