It can be hard to recall all the details of how a program and API work. The usual way to handle that is to look at the manual or a book. Another – and in my opinion – nice way is to have built-in help, so you can find the information without changing between the program and browser. This blog discuss how to obtain help when you use MySQL Shell.

MySQL Shell is a client that allows you to execute queries and manage MySQL through SQL commands and JavaScript and Python code. It is a second generation command-line client with additional WebOps support. If you have not installed MySQL Shell yet, then you can download it from MySQL’s community downloads, Patches & Updates in …

There are many organizations where front/web-facing applications use MySQL and back end processing uses PostgreSQL®. Any system integration between these applications generally involves the replication—or duplication—of data from system to system. We recently blogged about pg_chameleon which can be used replicate data from MySQL® to PostgreSQL. mysql_fdw can play a key role in eliminating the problem of replicating/duplicating data. In order to eliminate maintaining the same data physically in both postgres and MySQL, we can use mysql_fdw. This allows PostgreSQL to access MySQL tables and to use them as if they are local tables in PostgreSQL. mysql_fdw can be used, too, with …

We received feedback about how a member should act when leaving the group. And the majority of users wanted that when a node drops out of the group, it should kill all connections and shutdown. I totally agree with that behavior and it’s now the default in MySQL 8.0.12.

This new feature is explained in WL#11568.

Before this change, the server goes into super read only mode when dropping out of the group and allows users connected to this server or new connections (if you don’t use the router) to read old data.

Let’s check this out in the following video:

So now in MySQL 8.0.12, there is a mnew option called …

MySQL supports three types for binlog format. For safer binlog based replication its recommended to use ROW based replication. But even though in some worst cases this leads to data inconsistency. Later MySQL came up with the concept of GTID (global transaction identifiers) which generates the unique binlog entries to avoid any data inconsistency. This …

The post MySQL GTID vs MariaDB GTID appeared first on SQLgossip.

After installing MySQL 5.7.22 and PHP 7.1.17 on Fedora 27, you need to install the mysqli library. You need to verify if the mysqli library is installed. You can do that with the following mysqli_check.php program:

Check mysqli Install<?php if (!function_exists('mysqli_init') && !extension_loaded('mysqli')) {
    print 'mysqli not installed.'; }
  else {
    print 'mysqli installed.'; }
?>

You test preceding PHP program with the following URL in a browser:

http://localhost/mysqli_check.php

If the mysqli program isn’t installed, you can install it as follows by opening the yum interactive shell:

[root@localhost html]# yum shell

Protecting the data stored in your database may have been at the top of your priorities recently, especially with the changes that were introduced earlier this year with GDPR.

There are a number of ways to protect this data, which until not so long ago would have meant either using an encrypted filesystem (e.g. LUKS), or encrypting the data before it is stored in the database (e.g. AES_ENCRYPT or other abstraction within the application). A few years ago, the options started to change, as Alexander Rubin discussed in …
