6 SQL Tips And Tricks For Advanced Developers

3 Ways to Save Time When Coding SQL

Most developers, when writing in SQL, tend to spend too much time coding. While this is okay for projects that have the luxury of an easy deadline, the norm is that most database management systems require that their projects be completed within very tight deadlines. In such scenarios, there are always tips and tricks to help speed up the process of coding without compromising on the quality.

  1. Configuring your preferences
  2. Using keyboard shortcuts
  3. Create and use templates wherever possible
  4. Choose The Right Language And Think Ahead
  5. Secure Your Databases
  6. Compliant Code

Check this short introduction to SQL for beginners and ways to save time when coding in SQL:

1. Configuring your preferences:

This is a no-brainer. When using any software to code in SQL, configuring the preferences according to your needs is crucial. It helps you get familiar with the software and gives you the freedom to decide what options you need for that particular requirement. As there are bound to be lots of options, enabling the ones that you don’t require tends to take a toll on the machine as it ends up consuming more resources, thus slowing the system down.

Therefore, it is advisable to disable any options and extensions you don’t use so that the software runs leaner and with a simplified interface, eventually making it easy for you to navigate. While you might think that this is common knowledge, you’d be surprised at how much of a difference this little tip makes to speed up the coding.

2. Using keyboard shortcuts:

Again, this is another elementary tip that many developers don’t use. Before you start SQL coding, some of the SQL basics for beginners that you need to learn about are the keyboard shortcuts for the software you’re about to use. Take some time off and read through the documentation of the software to properly understand its features and catch up on the various keyboard shortcuts that are available. If you’re finding it tough to remember them, then it’s highly recommended that you physically write it down on a post-it note and stick it onto your desk so that you can look it up quickly without having your workflow interrupted.

Using keyboard shortcuts helps save you a lot of time as you don’t need to reach out for the mouse every now and then. This effectively speeds up the coding process and improves productivity as well. From swiftly toggling between open tabs to executing a highlighted query, almost everything can be accomplished in the blink of an eye using keyboard shortcuts.

3. Create and use templates wherever possible:

While you might think that this is common knowledge, you’d be surprised at how many developers are unaware of how effectively this little tip helps speed up the coding process. Yes, I agree that creating templates might not be possible when you’re busy working on a project. But then templates are huge time-savers if you take the time to properly design and create them. They help ease your workflow and allow you to re-use large segments of the code instead of painstakingly writing them all over again. There are a number of advantages to using templates apart from the ability to re-use code, such as –
a) Easy duplication, without having to configure and specify the data parameters more than once
b) Easy and rapid editing of existing templates to suit the needs and requirements of the project you’re working on
c) Effortless sharing across systems, as the templates can be simply copied from one computer to another
Following these three tips make things smooth for SQL coding for beginners as well as any developer. After all, a good developer isn’t the one who works harder, but the one who works smarter.

4. Choose The Right Language And Think Ahead:

It is common for developers to choose any language for their job. It might get the job done, but they should be pro-active while doing so. For instance, you can write an SQL query that can work just fine on 100 rows of data, but it will struggle to work with say 10000+ rows of data. To overcome the limitations, you should be smart enough to choose the right language and write your query so that it can adjust nicely when the number of rows grows large.

5. Secure Your Databases:

As a developer working with SQL, you also need to ensure that database is secure! As databases contain data and are centralized in its nature, it is the number one target for hackers. The hackers try every trick in their book to get illegal access to the database so that they can steal data and sell them for millions in the black market. So, what all of these means for a developer like you?

Well, you need to make sure that your database is as secure as possible. In most cases, the code written by you can have some critical security vulnerabilities. This can result in system compromise, and you can be held responsible for it. The best way to tackle this is to write code and test it for vulnerabilities before you make it live.

The implementation, however, depends on the database type you are using. If you are using MySQL with PHP, then you may want to escape parameters. Also, you need to be proactive in protecting your database against common threats such as SQL injection.

6. Compliant Code:

Over the years, SQL has evolved. The changes are documented and standardized so that developers know what’s the best version to work on. ANSI and ISO do SQL Standardization. And, if you are using SQL based on standards, then you should be using the latest SQL: 2019, then you must be using multi-dimensional arrays. However, if you are still using the older standardized version, you can access other features.

In short, it is essential to write standard-compliant code. This will improve maintainability and ensure that your code maintains the cross-platform standardization set by your organization.
