Six years ago I wrote a common lookup post to illustrate the effectiveness of things used throughout your applications. Now, I’m updating my student image with a more complete solution to show how to avoid update anomalies.

In the prior post, I used a while loop in PHP, like the following:

do {
      ...
} while($stmt->next_result());

Using PHP Version 7.3.8 and MySQL 8.0.16, that now raises the following error message:

Strict Standards: mysqli_stmt::next_result(): There is no next result set. Please, call mysqli_stmt_more_results()/mysqli_stmt::more_results() to check whether to call this function/method in /var/www/html/app/library.inc on line 81

You can see this type of error when you set the following parameters in your file during testing:

ini_set('display_errors',1); …

Somebody didn’t like the MySQLi Update Query example on the tutorialspoint.com website because it use the procedure mysqli_query style. Here’s a simple example of using the object-oriented method version. More or less, instead of query it uses the more intuitive execute() method.

The update_member function contains the logic and below it is a call to the test the function. It relies on a MySQLCredentials.inc file that contains the hostname, user name, password, and database name. You can create create member table, like my example in MySQL 8, or any other table in your MySQL database.

<?php /*
||  Function Name: update_member
*/
function update_member($account_number, $member_type, …

Laravel 6 is recently released with many enhancements, so we'll be learning, throughout this tutorial series how to create an example REST API CRUD application from scratch. The application we'll be building is a simple CRM with a MySQL database that exposes a set of RESTful API endpoints.

Introducing REST APIs

According to Wikipedia:

Representational State Transfer (REST) is a software architectural style that defines a set of constraints to be used for creating Web services. Web services that conform to the REST architectural style, termed RESTful Web services (RWS), provide interoperability between computer systems on the Internet.

REST stands for REpresentational State Transfer. It's an architectural style for distributed systems invented by Roy Fielding in 2000.

Overview The Skinny

Part of the power of Tungsten Clustering for MySQL / MariaDB is the ability to perform true zero-downtime maintenance, allowing client applications full access to the database layer, while taking out individual nodes for maintenance and upgrades. In this blog post we cover various types of maintenance scenarios, the best practices associated with each type of action, and the key steps to ensure the highest availability.

Important Questions Understand the Environment as a Whole First

There are a number of questions to ask when planning cluster maintenance that are critical to understand before starting.

For example:

1. What is the cluster topology?
   • Standalone (connectors write to single cluster master)
     Single cluster: …

Up to now, the way of updating dbdeployer was the same as installing it for the first time, i.e. looking at the releases page, downloading the binaries for your operating system, unpacking it and finally replacing the existing binaries.

This is not the procedure I follow, however, as for me updating means just compile the latest version I have just finished coding. For this reason, when Simon Mudd mentioned to me that dbdeployer should update itself over the Internet, I didn’t immediately grasp the concept. But then …

Deployment and management your database environment can be a tedious task. It's very common nowadays to use tools for automating your deployment to make these tasks easier. Automation solutions such as Chef, Puppet, Ansible, or SaltStack are just some of the ways to achieve these goals.

This blog will show you how to use Puppet to deploy a Galera Cluster (specifically Percona XtraDB Cluster or PXC) utilizing ClusterControl Puppet Modules. This module makes the deployment, setup, and configuration easier than coding yourself from scratch. You may also want to check out one of our previous blogs about deploying a Galera Cluster using Chef,  “How to Automate Deployment of MySQL Galera Cluster Using S9S CLI and Chef.”
