What do these timeouts do in MySQL? If you search the web for one or more of these, you may find complaints that no comprehensive explanation exists for all of these timeouts in one place (besides the obvious documentation of dynamic server system variables in MySQL). This blog post seeks to provide a central documentation source for timeouts and provide some practical explanation.

Knowing what timeouts do helps in a troubleshooting effort. It’s good to understand when an issue is timeout related and when it’s not, and to know the right reasons for changing timeout variables, or the right time to ask the developer or ad-hoc user to please tune the variables in the session, instead of …

The MySQL Workbench tool is great for development and administration tasks. Also it's available on Windows, Linux and Mac OS X which, according to information from third party sources, is more than you can say for most of the other equivalent tools. And Workbench is free. Having said that, most of the provided functionalities are intuitive and of daily use for developer and DBA staff alike.

I've tried out Idera's MySQL Query Explorer, a free tool and I found it easy to use and simple to setup. The only improvement that can be suggested is to add, on the technical requirements page, that your MySQL instance (MySQL Server version 5.5 and newer) must be running with the performance_schema turned on. Otherwise the tool will just display an empty grid. After you've successfully set

In this blog, we’ll discuss how to use “plugin: auth_socket” to change user password in MySQL 5.7. In

In Debian/Ubuntu it is pretty common to install MySQL/Percona Server with an empty password for the root user. After everything is configured and tested, then a password is set. This is not a good practice in production servers (or soon-to-be production servers), but you can do it for your own test servers. With regards to authentication, things have changed a bit in 5.7, and methods that worked before now need a different procedure.

Let’s say that you install 5.7 and don’t specify a password. You will see the following:

SELECT User, Host, HEX(authentication_string) FROM mysql.user; …

As doc states:

https://dev.mysql.com/doc/refman/5.7/en/innodb-page-compression.html

To disable page compression, set COMPRESSION=None using ALTER TABLE. Writes to the tablespace that occur after setting COMPRESSION=None no longer use page compression. To uncompress existing pages, you must rebuild the table using OPTIMIZE TABLE after setting COMPRESSION=None.

ALTER TABLE t1 COMPRESSION="None";
OPTIMZE TABLE t1;

With regular table there is no table rebuild:

mysql> alter table sbtest4 compression='none';
Query OK, 0 rows affected (0,01 sec)
Records: 0 Duplicates: 0 Warnings: 0

So the rebuild will be on optimize table run.

But if you want table rebuild each time when you run compression=’none’ you can add encryption=’N’ option

The JSON Functions for using MySQL 5.7 are overwhelming at first glance. A peek at documentation such as the JSON Modification Functions may make you shy at proceeding further. In previous posts the functions to create JSON documents for use in a MySQL column and the functions to get the meta information about JSON documents have been covered. And how to use the built-in JSON functions from PHP have been covered. But now it is time to cover modifying JSON data. Appending Lets start at the beginning and ask the server for a JSON array with the values of 1, 2, 3, 4, and 5.

mysql> select JSON_ARRAY(1,2,3,4,5);
+-----------------------+
| JSON_ARRAY(1,2,3,4,5) |
+-----------------------+
| [1, 2, 3, 4, 5]       |
+-----------------------+
1 row in set (0.00 sec)
