Select Star SQL VS SQL query for CSV

• Completely Free
  Select Star SQL is entirely free to use with no paywalls, subscriptions, or hidden costs. This makes it accessible to anyone who wants to learn SQL regardless of their financial situation.
• Interactive Hands-On Learning
  The platform provides an interactive SQL environment directly in the browser where learners can write and execute real SQL queries against actual datasets, reinforcing concepts through practice rather than passive reading.
• Real-World Dataset
  The course uses a compelling real-world dataset about Texas death row executions, which makes the learning experience more engaging and meaningful compared to abstract or contrived examples.
• Well-Structured Progressive Curriculum
  The course is organized in a logical progression from basic SELECT statements to more advanced concepts like aggregations, joins, and subqueries, allowing learners to build knowledge incrementally without feeling overwhelmed.
• No Setup Required
  There is no need to install any software, set up a database, or configure an environment. Learners can start writing SQL queries immediately in their web browser, removing a significant barrier to entry for beginners.

Possible disadvantages

• Limited Scope
  The course covers only fundamental SQL concepts and does not address more advanced topics like window functions, CTEs, indexing, database design, or performance optimization, which are essential for professional SQL usage.
• Single Database Dialect
  The platform teaches SQL using SQLite, and does not cover syntax differences or features specific to other popular database systems like PostgreSQL, MySQL, SQL Server, or Oracle, which learners may encounter in real jobs.
• No Certificate or Credential
  Completing the course does not provide any formal certificate, badge, or credential that learners could use to demonstrate their SQL skills to potential employers or on professional profiles.
• Limited Practice Exercises
  While the course includes some exercises, the total number of practice problems is relatively small compared to dedicated SQL practice platforms, which may not be sufficient for learners who need extensive repetition to solidify their skills.
• Single Dataset Can Feel Restrictive
  Using only one dataset throughout the entire course means learners do not get experience working with diverse data schemas, table relationships, or different types of data, which limits exposure to varied real-world scenarios.

• Familiarity
  SQL syntax is widely used and familiar to many developers, making it easier for them to query CSV data without learning a new query language.
• Expressiveness
  SQL is a powerful language with a rich set of features, allowing complex queries, joins, and aggregations on CSV data.
• Ad-hoc Analysis
  Users can perform quick and efficient ad-hoc data analysis directly on CSV files without needing to import the data into a database.
• Accessibility
  Online tools like try.csv-query.ca make it easy to query CSV files directly from the browser, increasing accessibility for users.

Possible disadvantages

• Performance Limitations
  Handling large CSV files in memory might lead to performance issues, as CSV files are not optimized for querying compared to databases.
• Limited Data Integrity
  CSV files lack data types and constraints, which can lead to errors or unexpected results when querying data, compared to structured databases.
• Lack of Security
  CSV files can be easily modified or corrupted, and querying them directly may expose sensitive data if not properly managed.
• Resource Intensive
  Running complex queries on large CSV files can be resource-intensive and may not be suitable for environments with limited computational resources.
