Since being released in 1995, MySQL has grown to become one of the most popular database management systems. The last two decades have seen a consistent stream of improvements and updates, and the platform is powerful and stable as of today. If you are a MySQL developer, you probably have come to terms with the system and how to navigate it, but could do with some pointers for carrying out your day to day DBA duties.
Create Proper Indices and Match Column Types
MySQL JOINs are tricky to carry out and require proper optimization to be carried out. Ensure that you have indexed the columns on both tables if you have multiple JOIN queries. Joined columns necessarily have to be of the same type, with string columns having the encoded characters. This should be kept in mind.
Optimize Your Queries
There are a number of ways you can optimize your queries so that they take less processing power and time to execute. It is worth noting that query caching is enabled on MySQL servers, so you can use it for retrieving cache results with the database engine when running a single query multiple times. If there are issues, you can always consult an expert at remoteDba.com.
Use the Delay_Key_Write Function
By default, MySQL keeps delay_key_write off due to the risk of a corrupted database if your project crashes. You can, however, turn it on yourself so that the MyISAM key file will remain intact even after a writing process. This saves a lot of time when the process is being executed in the future. This performance change will be very noticeable.
Use LIMIT 1 with WHERE Clauses
If you are looking for a single specific row in your queries, performance can be optimized by using LIMIT 1. It is really simple to use and will give you the results record by record instead of the entire table at once.
Stay Away from the Dump Files
MySQL’s dump files appear to be text files that can be read using the appropriate viewers, but the moment you try to edit them using a text editor, you will notice corruption across the entirety of the file. This is not desirable, and dump files might be useful for data recovery, so you should leave them alone.
Use the EXPLAIN Keyword for Queries
MySQL’s convenience, flexibility, and simplicity have attracted millions of developers over the years. One of these features is the EXPLAIN keyword, that will provide a breakdown of the query performance. You can then proceed to understand the process by which the indices used are scanned. All you have to do is add “EXPLAIN” before any query, and the result will appear.
There are not a lot of platforms better than MySQL when it comes to database administration. Once you get a grip on some of these features and tips that let you make the most of your database server, you will find the DBA job to be smooth sailing. It is always a good idea to stay updated with the latest tutorials and practices.
7 Tips to Avoid Viruses and Trojans on Your PC

Some viruses operate by adding external devices such as USB / Flash drives, external hard drives or network drives. Windows users can disable the auto-run function following the instructions according to their version of operating system.
- Do not “click” on links in emails or attachments
Sometimes by distraction, users end up “clicking” on attachments they receive via email, even knowing that it is a risky action for their computers. Once this is done, the result may not be visible at the moment, but a virus or Trojan may be acting in the computer’s memory, recording and stealing sensitive information.
