When I use MySQL workbench and get a huge dataset, i find it annoying that if I accidentally click on a row, workbench tries to order the data by that row - generally taking several minutes to complete.
I'm of the opinion that if I wanted a dataset ordered a particular way, I would have used an order-by clause.
Is there any way to disable the behavior of ordering a dataset by clicking on a particular column?
Unfortunately I think you're out of luck in this regard, unless of course you download the source code for MySQL Workbench and change the way the UI behaves and add in an option to disable column ordering on click.
Source is available here. (Change the 'select platform' drop down to 'Source Code')

I am the superuser of a particular database schema. Therefore I have all privileges on the tables in this schema, including ALTER DELETE UPDATE and INSERT.
I am administrating this database using the GUI MySQL Workbench 6.3. I used to select rows and to obtain a read-only result grid, which was convenient because it prevented me from accidentally editing data in my table.
This was indicated by a 'read only' flag in the bottom right corner of the result grid (see below).
However, I did not change anything in the structure of the table, and now when I select rows I am able to edit data and the 'read only' flag has disappeared.
I find it a bit unsecure because it would mean I could accidentally edit data in the table by mistyping.
How could I revert to a read-only result display?
The rules that allow editing a result set are very strict. The select query must be a plain one - no aggregate functions, no joins, no unions. There must be a primary key which is used to address the records to be changed.
Update: it wasn't necessary to worry about accidentally editing records in the table while not being in read-only mode.
Indeed, if you change a record in the table (in the screenshot below, I changed a year from 2010 to 2020), for this change to be actually committed in the database, you would need to click the "apply" button in the bottom right corner.
Moreover, upon closing the tab, you are asked whether or not you want to save changes. Consequently, if you accidentally edited a record, you just have to click "Don't save" upon closing the tab.
I'm a java dev who uses Mysql Workbench as a database client and IntelliJ IDEA as an IDE. Every day I do SQL queries to the database from 5 up to 50 times a day.
Is there a convenient way to save and re-run frequently used queries in Mysql Workbench/IntelliJ IDEA so that I can:
avoid typing a full query which has already been used again
smoothly access a list of queries I've already used (e.g by auto-completion)
If there is no way to do it using Mysql Workbench / IDEA, could you please advise any good tools providing this functionality?
Thanks!
Create Stored Procedures, one per query (or sequence of queries). Give them short names (to avoid needing auto-completion).
For example, to find out how many rows in table foo (SELECT COUNT(*) FROM foo;).
One-time setup:
DELIMITER //
CREATE PROCEDURE foo_ct
BEGIN;
SELECT COUNT(*) FROM foo;
END //
DELIMITER ;
Usage:
CALL foo_ct();
You can pass arguments in in order to make minor variations. Passing in a table name is somewhat complex, but numbers of dates, etc, are practical and probably easy.
If you have installed SQLyog for your mysql then you can use Favorites menu option in which you can save your query and in one click it will automatically writes the saved query on Query Editor.
The previous answers are correct - depending on the version of the Query Browser they are either called Favorites or Snippets - the problem being you can't create sub-folders to group them. And keeping tabs open is an option - but sometimes the browser 'dies' - and you're back to ground 0. So the obvious solution I came up with - create a database table! I have a few 'metadata' fields for descriptions - the project a query is associated to; problem the query solves; and the actual query.
You could keep your query library in an SQL file and load that when WB opens (it's automatically opened when you restart WB and that file was open on last close). When you want to run a specific query place the caret in it's text and press Ctrl+Enter (Cmd+Enter on Mac) to run only this query. The organization of that SQL file is totally up to you. You have more freedom than any "favorites" solution can give you. You can even have more than one file with grouped statements.
Additionally, MySQL Workbench has a query history (see the Output Tab), which is saved to disk, so you can return to a query even month's after you wrote it.
I'm trying to find the preference settings to have the output clear every time my statement or set of statements are executed. I would prefer this option instead of right clicking and clearing the output every time I want to. I just can't find it and I'm not sure it exists as an option.
There's no such thing like auto-clearing. If you want that implemented file a feature request in the MySQL bug system (http://bugs.mysql.com).
in navicat you can arrange the order of the columns but i have yet to find a way to sync the changes with the database. i saw a similar question here -> Rearrange column order in Sqlyog but haven't found anything similar in navicat. i have many tables that need to be fixed for export to excel and the order is important in the readability/presentation. typing out sql code for each move would be way too tedious. thanks in advance.
you can't do it in navicat , you have to run a sql query for that purpose
You can reorder columns using SQLyog. To change the sequence of columns in a table, select the table in the Object Browser and select Table -> More Table Operations -> Reorder Column(s) (Ctrl+Alt+R) from the popup menu.
Select any column and click Up or Down button to move the column up / down. Having re-sequenced the columns, click Re-Order to save the table with changed structure. The column data in the table gets re-arranged accordingly.
This is a really old question i Stumbled on going to answer just in case someone needs
Navicat provides the ability to change the column order in a table by using the design table feature
Either right click on the table name or press ctr-d on the top of the screen there are arrows to move a column up or down
By pressing on the SQL preview tab on the top you can actually see the ALTER TABLE statements navicat is going to run
You can also copy-paste this Statement and run on any other test database you may have or as a git migration
Its a good idea to always read the SQL Preview as some times Navicat may use DROP statements and you would want to take a backup before something like that
I'm trying to track down a bug that's deleting rows in a mysql table.
For the life of me I can't track it down in my PHP code, so I'd like to work backwards by finding the actual mysql query that's removing the rows.
I logged in to phpmyadmin, but can't find a way to view the history of past sql operations.
Is there a way to view them in phpmyadmin?
Ok, so I actually stumbled across the answer.
phpMyAdmin does offer a brief history. If you click on the 'sql' icon just underneath the 'phpMyAdmin' logo, it'll open a new window. In the new window, just click on the 'history' tab.
That will give you the last twenty or so SQL operations.
There is a Console tab at the bottom of the SQL (query) screen. By default it is not expanded, but once clicked on it should expose tabs for Options, History and Clear. Click on history.
The Query history length is set from within Page Related Settings which found by clicking on the gear wheel at the top right of screen.
This is correct for PHP version 4.5.1-1
You just need to click on console at the bottom of the screen in phpMyAdmin and you will get the Executed history:
To view the past queries simply run this query in phpMyAdmin.
SELECT * FROM `mysql`.`general_log`
if it is not enabled, run the following two queries before running it.
SET GLOBAL log_output = 'TABLE';
SET GLOBAL general_log = 'ON';
I don't think phpMyAdmin lets you do that, but I'd like to hear I'm wrong.
On the other hand you can enable query logging in MySQL: The General Query Log
Yes, you can log queries to a special phpMyAdmin DB table.
See SQL_history.
I am using phpMyAdmin Server version: 5.1.41.
It offers possibility for view sql history through phpmyadmin.pma_history table.
You can search your query in this table.
pma_history table has below structure:
You have to click on query window just below the phpMyAdmin logo, a new window will open.
Just click on SQL History tab. There you can see history of SQL Queries.
OK so I know I'm a little late and some of the above answers are great stuff.
As little extra though, while in any PHPMyAdmin page:
Click SQL tab
Click 'Get auto saved query'
this will then show your last entered query.
I may be wrong, but I believe I've seen a list of previous SQL queries in the session file for phpmyadmin sessions
Here is a trick that some may find useful:
For Select queries (only), you can create Views, especially where you find yourself running the same select queries over and over e.g. in production support scenarios.
The main advantages of creating Views are:
they are resident within the database and therefore permanent
they can be shared across sessions and users
they provide all the usual benefits of working with tables
they can be queried further, just like tables e.g. to filter down the results further
as they are stored as queries under the hood, they do not add any overheads.
You can create a view easily by simply clicking the "Create view" link at the bottom of the results table display.
you can run your past mysql with run /PATH_PAST_MYSQL/bin/mysqld.exe
it run your last mysql and you can see it in phpmyadmin and other section of your system.
notice: stop your current mysql version.
S F My English.
why dont you use export, then click 'Custom - display all possible options' radio button, then choose your database, then go to Output and choose 'View output as text' just scroll down and Go. Voila!
There is a tool called Adminer which is capable of doing all phpmyadmin job packed in single tiny php file.
