Frequently Asked Questions
What is SQL?
SQL (Structured Query Language) is a programming language that enables users to communicate with databases. It is considered the primary language used with relational databases. SQL statements allow users to combine data from multiple tables, sort, filter, aggregate, extract data and query databases. You will learn these functions in our SQL training course.
How is SQL used for data analysis?
Businesses are accumulating data at an increasingly fast rate. This data is valuable if management can use it to support and drive more effective decision-making. Data analytics involves analysing data to produce meaningful insights, identify patterns and present findings in visualisations. It is the art of finding meaning in data. To get the most out of this data, SQL training is a must.
Why learn SQL language certification?
Organisations are increasingly gathering and storing customer and client data, and having access to this data can help in all sorts of ways. Our SQL course and certification could be the key to accessing this data. Learn more about the benefits of learning SQL.
What skills will I learn in an SQL training course?
You’ll learn to confidently work with databases — from writing simple queries to extracting complex data sets. You’ll understand how to create and manage tables, use joins to connect data across multiple sources, apply filters, group and summarise results and write efficient queries that deliver clear insights. Advanced courses may also cover subqueries, stored procedures and how to fine-tune performance.
Are there any prerequisites to an SQL language course?
Most beginner courses don’t require any prior experience — just basic computer skills and a willingness to learn. If you’ve already worked with data or spreadsheets before, you’ll likely pick things up quickly. For more advanced modules, having prior experience with database concepts or SQL can help, but it’s not essential.
How long does an SQL language certification course take?
It depends on the course and how it’s delivered. Short SQL certification bootcamps can be done in a few days, while more in-depth programs might stretch over several weeks. At Nexacu, our training is designed to give you practical, job-ready skills in a format that suits your schedule — either learning full-time or alongside work.
What is the difference between SQL and MySQL?
SQL is the language used to manage and query data in relational databases. MySQL, on the other hand, is one of many database management systems that use SQL. Think of SQL as the language and MySQL as one of the tools that speaks it — just like you can speak English in many different countries, but each country has its own context and dialect.
What jobs can you get after completing an SQL certification?
SQL is a core skill in a huge range of data and tech roles, so after completing an SQL certification course, you’ll be well-positioned for entry-level positions like data analyst, business analyst, database administrator and junior developer. It’s also a powerful upskilling tool if you're already in marketing, finance or operations and want to make more data-driven decisions.
Do I need to know programming to learn SQL?
Not at all. SQL is a great entry point into tech because it’s structured, readable and doesn’t require a programming background. If you’re comfortable with spreadsheets or curious about working with data, you’ll find SQL simple — and surprisingly empowering.
