SQL, also known as Structured Query Language, is a powerful tool to search through large amounts of data and return specific information for analysis. Learning SQL is crucial for anyone aspiring to be a data analyst, data engineer, or data scientist, and helpful in many other fields such as web development or marketing.

In this cheat sheet, you'll find a handy list of functions covering querying data, filtering data, aggregation, and more—all collected from our [**SQL Fundamentals Skill Track**](https://www.datacamp.com/tracks/sql-fundamentals).

**The Different Dialects of SQL**

Although SQL languages all share a basic structure, some of the specific commands and styles can differ slightly. Popular dialects include MySQL, SQLite, SQL Server, Oracle SQL, and more. PostgreSQL is a good place to start —since it’s close to standard SQL syntax and is easily adapted to other dialects.

With this SQL cheat sheet, you'll have a handy reference guide to basic querying tables, filtering data, and aggregating data
