Handling Error Messages and Warnings with MySQL

To ensure that your MySQL Database works as efficiently as possible, it is important to know how to handle error messages and warnings.

Error messages have three components:

  • A MySQL-specific error code, such as 1146
  • A SQLSTATE error code. These codes are defined by standard SQL and the ODBC standard.
  • A text message that describes the problem

MySQL Server generates a warning when it is not fully able to comply with a request or when an action has possibly unintended side effects. You can display these warnings with the SHOW WARNINGS statement.

To learn about handling error messages and warnings along with other developer topics, consider taking the MySQL for Developers training course.

You can take this 5-day course as a:

  • Live-virtual event: Attend a live training event from your own desk, no travel required. Choose from a selection of events on the schedule to suti different timezones.
  • In-class event: Travel to an education center to attend a class. Below is a selection of the events already on the schedule.

Normalize Your MySQL Database For Efficient Data Access, Query Flexibility and Maintenance

Before you start creating database entities, spend some time designing your database to ensure that it is fit for your purpose. The time you invest in this process saves a lot of time and trouble later. Professional database designers fine-tune their design using a process called 'normalization'. The normalization process takes your database design through a number of 'normal forms', which aim to ensure efficient data access, greater query flexibility, and easier maintenance.

For example, the First Normal Form (or '1NF') ensures that all your database columns contain only a single value. A column that contains multiple data values is difficult to access and keep up to date. It also ensures that each table row only represents a single 'real world' item. Like all the other normal forms, this encourages you to split your data across multiple tables, with less rows in each table. You can quickly see the benefits of this approach as your database grows.

To learn more about normalization and other topics that help you get started with the MySQL database, take the MySQL for Beginners training course. You can take this 4-day training course as:

  • Training-on-Demand: Start training within 24 hours of registering. Follow lectures through streaming video at your own pace and book time on a lab environment to suit your own schedule.

Optimizing MySQL, Improving Performance of Database Servers

Optimization involves improving the performance of a database server and queries that run against it. Optimization reduces query execution time and optimized queries benefit everyone that uses the server. When the server runs more smoothly and processes more queries with less, it performs better as a whole. To learn more about how a MySQL developer can make a difference with optimization, take the MySQL Developers training course.

This 5-day instructor-led course is available as:

  • Live-Virtual Event: Attend a live class from your own desk - no travel required. Choose from a selection of events on the schedule to suit different timezones.

Securing User Account Details with MySQL

Keeping user account details secure is always at the forefront of a Database Administrator's mind. However, users want to get up and running as soon as possible without complex login procedures.

You can learn more about this and many other topics in the MySQL for Database Administrator course.

For example, MySQL 5.6.6 introduced a new utility: mysql_config_editor, which makes secure access via MySQL client applications much easier to establish, while still providing a good measure of security.

The mysql_config_editor stores a user's authentication details in an encrypted login file called mylogin.cnf. This login file is readable and writable for the user who invokes the utility, and invisible to everyone else. You can use it to collect all your hard-to-remember server locations and paswords safe in the knowledge that your passwords are never invoked using clear text.

The MySQL for Database Administrators course is a 5-day instructor-led course which is available as a:

  • Training-on-Demand: Start training within 24 hours of registration, following lecture material at your own pace through streaming video and booking time on a lab environment to suit your schedule.

Benchmarking MySQL Performance

Benchmarking lets you test how a system responds when it is given work to do, and removes the guesswork from your performance tuning efforts. The workloads you use when benchmarking are very different from real life deployments, which can be extremely variable. If you remember this, benchmarking is extremely useful, enabling you to measure current performance and determine the performance impact of any changes. Such changes could be the addition of new hardware or opening up your application to more users.

Benchmarking is one of the topics that you can learn more about by taking the MySQL Performance Tuning course. You can take this course in the following formats:

  • Training-on-Demand: Start training within 24 hours of registration, following lecture delivery at your own pace and scheduling time on a lab environment at your convenience.

Developing with MySQL and NoSQL

MySQL adopts a very different approach to 'NoSQL' than other databases. With the memcached plugin, MySQL provides the speed and high availability benefits of a standard 'NoSQL' database solution, while mitigating many of the drawbacks to this approach.

A traditional memcached application bypasses the SQL layer entirely, and stores all its data in memory. This makes data access extremely fast, but there is a risk that the data will disappear in the event of a system problem. 

The MySQL memcached plugin for InnoDB also bypasses the SQL and optimization layers, resulting in excellent performance. It goes further, writing key-value data directly to  InnoDB tables. The result is fast data access while retaining the advantages provided by the existing relational database infrastructure, such as the ability to run complex queries with SQL, maintain data integrity, provide real-time analytics to the business, and work with big data platforms such as Hadoop.

MySQL Developers can learn about topics such as using NoSQL and memcached, as well as much more in the MySQL for Developers course.

This live 5-day instructor-led course is available as a:
