My problem:
I am trying to delete some important rows from multiple tables, around 20 tables, I am afraid that deleting the rows might cause some problem(I am not the creator of this website), so before deleting the rows I am selecting the rows and writing it into a file. But I write it as an array.
Is there a way to write it as an sql insert statement, to a file, so that it would be easy for me to update the database if there is some problem.
For me it would be easier to store the information in a way that would allow me to understand the data. Then IF I need it, I could mutate the data into an INSERT statement.
I strongly encourage you as a professional software engineer, to try not to solve a problem that you might encounter, until you DO encounter it.
If you use phpMyAdmin you can run a query that selects those rows, then click the Export link under Query results operations:
In the next page, select Custom - display all possible options and SQL Format:
Then, further down the page, select data under Format specific options:
And then press Go. You will be prompted to Save or Open a file, which will include the appropriate INSERT statements to recreate the data from those rows.
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).
What should I enable to get the other options in MySQL Workbench (version 6.0)
The edit elements in the toolbar only show up if your result is actually editable. There can be many reasons why this is not the case. Only resultsets form single table select queries can be edited and the result must include a unique key (in order to let MySQL Workbench address changed rows).
try editing with the option edit table data,or try editing data directly in the output you get as a result ,an option will come to apply or cancel that will update your data .
the option of apply/cancel is sometimes shows disabled but try moving to other tabs/columns it works for me you can try this.
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.
