in this tutorial, We ll concatenate two or multiple columns in MySQL.We will select the values and concat multiple columns using MySQL inbuilt method. It can also achieve same thing using programmatically. You need to select columns fields value separately from MySQL Table and store their values in the single variable after concat their values.

Introduction Welcome to a new issue of the High-Performance Java Persistence Newsletter in which we share articles, videos, workshops, and StackOverflow answers that are very relevant to any developer who interacts with a database system using Java. Articles From version 2.12, Percona PMM uses Victoria Metrics instead of Prometheus. Victoria Metrics provides better disk I/0 utilization and less memory usage. For more details about this change and its benefits, check out this article. By default, the MySQL JDBC Driver only emulates prepared statements. If you wonder whether server-side prepared statements perform better... Read More

If you run MySQL on Amazon RDS and use passwords, I sure hope you frequently rotate those passwords (among many other security best practices). But if you don’t rotate them, I might know why: it’s quite difficult to set up when you really get into it. It seems easy at first, but if you’ve ever tried you know how quickly it becomes complicated. At least, that was my experience. So to help others overcome the challenges and do frequent password rotation, I wrote up a long read: MySQL Password Rotation with AWS Secrets Manager and Lambda.

MySQL Password Rotation with AWS Secrets Manager and Lambda MySQL password rotation using Amazon RDS for MySQL, AWS Secrets Manager, and AWS Lambda is a complex challenge to automate at scale. It appears easy at first—just two services and some IAM resources, right? But actual implementation quickly reveals a significant depth of considerations, choices, trade-offs, and technical problems. This page is a detailed guide to implementing MySQL 5.7 password rotation—fully automated at scale—using AWS RDS, Secrets Manager, and Lambda, and Terraform for cloud infrastructure.

A lot of elements take part in a good backup strategy. Two of them are:

• Where to store your backups – Never on the same server. Preferable not in the same datacenter. Ideally far enough so you can restore in case of a natural disaster (region flood, extended local power outage, etc…).
• Retention period – The longer, the better.

Those points relate directly to costs. Storing a backup on an off-site facility cost money. Keeping the backups available to fulfill your retention period policy costs money.

The main cloud providers have different layers of storage often called Storage Class. Each layer has its own particularities and policies, but they come with an important factor – Cost!

We are happy to announce that starting at …

You only have to choose your favorite flavour to setup, administer, configure, backup or attach an analytics cluster to your MDS DB System, as Oracle maintains SDKs in several languages to integrate your software with Oracle Cloud Infrastructure.

And in particular today I’d like to test the SDK for Python, you can find an introduction here (but you have also SDKs for Java, Go, Ruby, Javascript, .NET). Read an introduction to SDKs.

First we will talk about some of the other internal users of the technology that underpins the InnoDB Clone. MySQL Enterprise Backup (MEB) is an enterprise offering that provides backup and recovery for MySQL. Among various types of backups available, the following two types are of interest to us:

• Full Backup – A backup that backs up the entire MySQL instance – all the tables in each MySQL database.
