Learn SQL at Your Own Pace: The Advantages of Online Practice
Are you looking to enhance your SQL skills but find it challenging to practice in a traditional classroom setting? Look no further. With online SQL practice, you can learn at your own pace and take your skills to the next level. In this article, we will explore the advantages of online SQL practice and how it can benefit both beginners and experienced professionals.
Convenience and Flexibility
One of the key advantages of online SQL practice is the convenience it offers. Traditional classroom settings often have fixed schedules, making it difficult for individuals with busy lifestyles or full-time jobs to find time for learning. However, with online platforms, you have the flexibility to learn whenever and wherever suits you best. Whether you prefer early mornings or late nights, all you need is an internet connection and a device to access the platform.
Moreover, online SQL practice allows learners to progress at their own pace. Everyone has different learning speeds and styles, so being able to control your learning journey is crucial. Unlike classroom-based courses where everyone follows a set curriculum, online platforms offer self-paced tutorials that allow you to spend more time on challenging topics or quickly move through familiar concepts. This flexibility ensures that learners can focus on areas they need the most help with without feeling rushed or held back by others.
Interactive Learning Experience
Another advantage of online SQL practice is its interactive nature. Traditional learning methods often involve lectures or reading textbooks without much hands-on experience until later stages. However, online platforms provide immediate access to practical exercises that reinforce theoretical knowledge.
Many online SQL practice platforms offer interactive coding environments where learners can write queries directly in a web browser. These environments usually provide real-time feedback on syntax errors or incorrect results, helping learners identify and correct mistakes promptly. Additionally, some platforms offer gamified elements such as challenges or competitions that make the learning process more engaging and enjoyable.
Comprehensive Learning Resources
When it comes to online SQL practice, learners are not limited to a single resource. Online platforms often provide a wealth of learning materials, including video tutorials, written guides, and practice exercises. This comprehensive approach ensures that learners have access to various resources that cater to different learning preferences.
Video tutorials are particularly valuable for visual learners as they can watch instructors explain SQL concepts and demonstrate how to write queries effectively. Written guides offer detailed explanations and examples that can be revisited at any time, making them ideal for those who prefer reading and taking notes. Practice exercises allow learners to apply what they have learned in a hands-on manner, solidifying their understanding of SQL principles.
Community Support and Collaboration
Lastly, online SQL practice platforms often foster a sense of community among learners. These platforms typically include discussion forums or chat features where users can interact with each other, ask questions, and share insights. This community support is invaluable as it creates opportunities for collaboration and peer learning.
Engaging with fellow learners who are also practicing SQL helps create a supportive environment where you can seek advice or discuss challenges you may encounter along the way. Additionally, some online platforms offer mentorship programs where experienced professionals guide beginners through their learning journey. This mentorship provides personalized guidance and expert insights that can greatly enhance the learning experience.
In conclusion, online SQL practice offers numerous advantages over traditional classroom settings. The convenience and flexibility it provides allow individuals to learn at their own pace without being restricted by fixed schedules. The interactive nature of online platforms enhances the learning experience by providing immediate feedback and practical exercises. The availability of comprehensive learning resources caters to various learning preferences, ensuring a well-rounded education in SQL. Lastly, the sense of community support fosters collaboration among learners, creating an environment conducive to growth and development. So why wait? Start your online SQL practice today.

10 Beginner SQL Practice Exercises With Solutions
- online practice
- sql practice
Solve these ten SQL practice problems and test where you stand with your SQL knowledge!
This article is all about SQL practice. It’s the best way to learn SQL. We show you ten SQL practice exercises where you need to apply essential SQL concepts. If you’re an SQL rookie, no need to worry – these examples are for beginners.
Use them as a practice or a way to learn new SQL concepts. For more theoretical background and (even more!) exercises, there’s our interactive SQL Basics course. It teaches you how to select data from one or more tables, aggregate and group data, write subqueries, and use set operations. The course comprises 129 interactive exercises so there is no lack of opportunities for SQL practice, especially if you add some of the 12 ways of learning SQL online to it.
Speaking of practice, let’s start with our exercises!
The question is always where to find data for practicing SQL. We’ll use our dataset for all exercises. No need to limit yourself to this, though – you can find other free online datasets for practicing SQL .
Our dataset consists of two tables.
The table distribution_companies lists movie distribution companies with the following columns:
- id – The ID of the distribution company. This is the primary key of the table.
- company_name – The name of the distribution company.
The table is shown below.
The second table is movies . These are the columns:
- id – The ID of the movie. This is the primary key of the table.
- movie_title – The movie title.
- imdb_rating – The movie rating on IMDb.
- year_released – The year the movie was released.
- budget – The budget for the movie in millions of dollars.
- box_office – The earnings of the movie in millions of dollars.
- distribution_company_id – The ID of the distribution company, referencing the table distribution_companies (foreign key).
- language – The language(s) spoken in the movie.
Exercise 1: Selecting All Columns From a Table
Exercise: Select all data from the table distribution_companies .
Solution explanation: Select the data using the SELECT statement. To select all the columns, use an asterisk ( * ). The table from which the data is selected is specified in the FROM clause.
Exercise 2: Selecting a Few Columns From a Table
Exercise: For each movie, select the movie title, the IMDb rating, and the year the movie was released.
Solution explanation: List all the columns needed ( movie_title , imdb_rating , and year_released ) in the SELECT statement, separated by the comma. Reference the table movies in the FROM clause.
Exercise 3: Selecting a Few Columns and Filtering Numeric Data in WHERE
Exercise: Select the columns movie_title and box_office from the table movies . Show only movies with earnings above $300 million.
Solution explanation: List the columns in SELECT and reference the table in FROM . Use a WHERE clause to filter the data – write the column box_office and use the ‘greater than’ operator ( > ) to show only values above $300 million.
Exercise 4: Selecting a Few Columns and Filtering Text Data in WHERE
Exercise: Select the columns movie_title , imdb_rating , and year_released from the table movies . Show movies that have the word ‘Godfather’ in the title.
Solution explanation: List the columns in SELECT and reference the table in the FROM clause. Use a WHERE clause to filter the data. After writing the column name, use the LIKE logical operator to look for ‘Godfather’ in the movie title, written in single quotes. To find the word anywhere in the movie title, place the wildcard character ( % ) before and after the word.
Exercise 5: Selecting a Few Columns and Filtering Data Using Two Conditions in WHERE
Exercise: Select the columns movie_title , imdb_rating , and year_released from the table movies . Show movies that were released before 2001 and had a rating above 9.
Solution explanation: List the columns in SELECT and reference the table in FROM . Set the first condition that the year released is before 2001 using the ‘less than’ ( < ) operator. To add another condition, use the AND logical operator. Use the same logic as the first condition, this time using the ‘greater than’ operator with the column imdb_rating .
Exercise 6: Filtering Data Using WHERE and Sorting the Output
Exercise: Select the columns movie_title , imdb_rating , and year_released from the table movies . Show movies released after 1991. Sort the output by the year released in ascending order.
Solution explanation: List the columns in SELECT and reference the table in FROM . Filter the data with WHERE by applying the ‘greater than’ operator to the column year_released . To sort the data, use an ORDER BY clause and write the column name by which you wish to sort. The type of sorting is specified by writing ASC (ascending) or DESC (descending). If the type is omitted, the output is sorted in ascending order by default.
Exercise 7: Grouping Data by One Column
Exercise: Show the count of movies per each language category.
Solution explanation: Select the column language from the table movies . To count the number of movies, use the aggregate function COUNT() . Use the asterisk ( * ) to count the rows, which equals the count of movies. To give this column a name, use the AS keyword followed by the desired name. To show the count by language, you need to group the data by it, so write the column language in the GROUP BY clause.
Exercise 8: Grouping Data by Multiple Columns
Exercise: Show the count of movies by year released and language. Sort results by the release date in ascending order.
Solution explanation: List the columns year_released and language from the table movies in SELECT . Use COUNT(*) to count the number of movies and give this column a name using the AS keyword. Specify the columns by which you want to group in the GROUP BY clause. Separate each column name with a comma. Sort the output using ORDER BY with the column year_released and the ASC keyword.
Exercise 9: Filtering Data After Grouping
Exercise: Show the languages spoken and the average movie budget by language category. Show only the languages with an average budget above $50 million.
Solution explanation: Select the column language from the table movies . To compute the average budget, use the aggregate function AVG() with the column budget in parentheses. Name the column in the output by using the AS keyword. Group the data by rating using GROUP BY . To filter the data after grouping, use a HAVING clause. In it, use the same AVG() construct as in SELECT and set the values to be above 50 using the ‘greater than’ operator.
Exercise 10: Selecting Columns From Two Tables
Exercise: Show movie titles from the table movies , each with the name of its distribution company.
Solution explanation: List the columns movie_title and company_name in SELECT . In the FROM clause, reference the table distribution_companies . Give it an alias dc to shorten its name for use later. The AS keyword is omitted here; you may use it if you wish. To access the data from the other table, use JOIN (it may also be written as INNER JOIN ) and write the table name after it. Give this table an alias also. The join used here is an inner type of join; it returns only the rows that match the joining condition specified in the ON clause. The tables are joined where the column id from the table distribution_companies is equal to the column distribution_company_id from the table movies . To specify which column is from which table, use the corresponding alias of each table.
That Was Fun! Now, Time to Do SQL Practice on Your Own!
These ten SQL practice exercises give you a taste of what practicing SQL looks like. Whether you are at the beginner, intermediate, or advanced level, it’s the same. What changes is the complexity of the problems you solve and of the code you write.
Look for more challenges in the SQL Basics course and the Monthly SQL Practice track. Both are excellent for your SQL practice online. This is true, especially if you do not have an opportunity to use SQL on a daily basis in your job.
So, don’t try to test how long it takes to forget what you once knew in SQL! Use every opportunity to solve as many SQL practice problems as possible.

Need SQL Assignment Help?
SQL (Structured Query Language) is used to manage data in relational databases. It is not a programming language and has no control flow statements or ability to perform computations. SQL is the standard for accessing data stored in the current big data platforms like Hadoop, NoSQL, and Apache Cassandra. A programmer needs to know how to write SQL queries to access, manipulate and update data from the database.
You can find tutorials and how-to guides for these SQL databases on the Internet, but it requires you to do a lot of Googling to find what you need. To help you with this tedious and time-consuming task, FavTutor has been assisting students in succeeding in their academics by helping them with their homework and assignment details. Our tutors have helped thousands of students across the globe reach their goals and graduation by solving their queries and doubts during their academics. We have a team of over 150 qualified tutors who are eager to help you succeed with your academic assignments while you focus on your practical ambitions.
What is SQL?
Structured Query Language (SQL) is a special-purpose programming language designed for managing data in relational database management systems (RDBMS). SQL is one of the most popular computer languages ever. It's used to create and manage databases central to most enterprise software systems.
Many web and mobile apps use SQL behind the scenes to store everything from your shopping cart to your search history. Because SQL is so widely used, there are many different dialects of the language—most notably Oracle SQL, MySQL SQL, and Microsoft SQL Server. Taken together these facts mean that you're almost certainly already working with SQL, even if you don't know it.
Types of SQL
Following are some of the types of SQL widely adopted by every enterprise around the globe:
- Data Definition Language (DDL)
- Data Manipulation Language (DML)
- Data Control Language (DCL)
- Data Query Language (DQL)
- Transaction Control Language (TCL)
Key Concepts of SQL
Let us emphasize understanding a few key topics that can be difficult for some students while working with SQL:
- Keys in SQL: The key is a single or combination of multiple fields in a table. A key enables you to select data from a database table using only a few characteristics, such as the database table name and the field name. Keys are also used to establish relationships among tables. Keys promote consistency by ensuring that related data appears in the same table.
- Views in SQL: Views are virtual tables that display the data stored in other tables. A view can display all or a few rows from a single table or many tables. Essentially, a view is an SQL query stored permanently in the database.
- SQL joins: In SQL, a JOIN operation combines records from two or more tables in a database. A JOIN links data from two tables by using values common to each. This operation may help retrieve data from two or more tables.
- Normalization: Normalization is a database design technique that reduces redundancy and dependency of data by dividing larger tables into smaller tables and linking them using relationships.
- Transaction in SQL: A transaction is a unit of work in which one or more changes are made to a database. A transaction propagates changes to the database in a logical order, whether manually by a user or automatically by some sort of program.
Advantages of SQL
SQL is a widely used, efficient programming language for communicating with databases. Some of the common advantages of SQL include the following:
- No coding skills: For data retrieval, there is no need for many lines of code. You need only essential SQL keywords--SELECT, INSERT INTO, UPDATE--as well as specific syntactic rules, which eventually make SQL a user-friendly language.
- Faster query processing: Using SQL query language, large amounts of data are retrieved quickly and efficiently, and therefore, you can perform operations such as insertion, deletion, and manipulation of data in a matter of seconds.
- Portable: SQL is a platform-independent query language and, therefore, can be used in PCs, servers, laptops, etc., consisting of any operating system.
- Standard language: SQL is a standardized structured query language supported by the International Organization for Standardization (ISO) and the American National Standards Institute (ANSI) used for relational databases. SQL’s lengthy, detailed, established documentation over the years has helped to set it as a solid programming language.
- Open source: Free, open-source databases developed by MySQL, MariaDB, and PostgreSQL means that you can use SQL databases at low cost and with help from a large community.

SQL Assignment Help, MySQL Database Homework Help
Every programmer is familiar with MySQL, because it’s the most widely used open-source relational database management system, and the second most used overall. It has a graphical user interface and command-line interface (such as MySQL Workbench), operational on many systems (Windows, Linux, and Mac), and has many features the same as commercial database management platforms such as Microsoft MSSQL and Oracle SQL. You might find yourself lost in all the tables you have to manage in the MySQL database (including stored procedures, triggers, etc.). Luckily we are here to provide students with SQL homework help. We offer a wide range of services and help with SQL:
- Planning and constructing new database (ERD using Microsoft Visio or draw.io)
- Managing database connections (e.g. connection to MS Access)
- Optimizing existing database (especially design!)
- Backup and restore database
- Procedures, Triggers, timers
- Reports, Forms, Queries, VBA...
And help with any other issues you might face… So if you wonder who can "help with my SQL homework" - WE CAN !
There is a wide range of possibilities for completing SQL assignments while incorporating other programming languages. On the other hand, there are not so many options for saving data: simple text files, XML, or relational databases. The best option is usually MySQL. Every server most commonly uses some SQL variant as their database platform, because most are free and reliable. In case you need help with SQL project setting up ERD – it is one of the database homework help services we provide. We will solve every problem you face in the SQL database at an affordable price.
We also can help you with Murach’s MySQL course.
SQL Assignments Are Easier with Our Help
Our team consists of experienced programmers, data analytics, information specialists who hold degrees in their fields. If you are in the middle of a difficult SQL database project, specifically stuck with a certain bug, Homework Help Online is happy to share the experience we have gained in many of years. Why would you need to puzzle yourself with such a thing as the database procedures or triggers? There’s a better option – ask the questions and get the answers, or just simply submit your task, fill in the requirements, and wait for your SQL assignment help to proceed. This is why the students like us. In case you don’t have enough time for completing your task (it is a common issue that one gets stuck with a database bug the last night!), a quick tip is the best option.
Typical university SQL assignment (full project) consists of:
- Business needs analysis, based on some partial information provided in the requirements (a.k.a. business rules)
- ERD design and drawing, including primary/foreign keys, relation types, and data types
- Database construction - a script of the correct order of tables CREATE queries and relations assignments
- Filling in the example data (not too much, but enough for the SELECT queries)
- Writing SELECT queries. This might be simple or very challenging, depending on the course you take
- Extra credit: writing triggers and procedures (this part is rare in our experience, however, it is important in the real systems)
Overall, all this struggle most likely leads you onto a great career path. Once mastered, database technology is used not only in websites but also in various ERP (enterprise resource management) projects. You don't deal with it while studying in university, but it might be a nice surprise to understand how the industry really operates. Starting from simple SQL projects and gaining momentum with database assignment help leads to an IT career path you never expected.
Frequently Asked Questions
Yes. No hidden fees. You pay for the solution only, and all the explanations about how to run it are included in the price. It takes up to 24 hours to get a quote from an expert. In some cases, we can help you faster if an expert is available, but you should always order in advance to avoid the risks. You can place a new order here .
The cost depends on many factors: how far away the deadline is, how hard/big the task is, if it is code only or a report, etc. We try to give rough estimates here, but it is just for orientation (in USD):
Credit card or PayPal. You don't need to create/have a Payal account in order to pay by a credit card. Paypal offers you "buyer's protection" in case of any issues.
We have no way to request money after we send you the solution. PayPal works as a middleman, which protects you in case of any disputes, so you should feel safe paying using PayPal.
No, unless it is a data analysis essay or report. This is because essays are very personal and it is easy to see when they are written by another person. This is not the case with math and programming.
It is because we don't want to lie - in such services no discount can be set in advance because we set the price knowing that there is a discount. For example, if we wanted to ask for $100, we could tell that the price is $200 and because you are special, we can do a 50% discount. It is the way all scam websites operate. We set honest prices instead, so there is no need for fake discounts.
No, it is simply not how we operate. How often do you meet a great programmer who is also a great speaker? Rarely. It is why we encourage our experts to write down explanations instead of having a live call. It is often enough to get you started - analyzing and running the solutions is a big part of learning.
Another expert will review the task, and if your claim is reasonable - we refund the payment and often block the freelancer from our platform. Because we are so harsh with our experts - the ones working with us are very trustworthy to deliver high-quality assignment solutions on time.
