In this intermediate SQL course, you’ll expand on your understanding of SQL fundamentals, sharpening your ability to join, filter, group, and analyze data.
Learn to use outer joins and identify NULL data. You’ll also discover how to group data and run common statistical calculations with aggregate functions. Working with data often requires changing the data type when it’s not in the format you need (using CAST), as well as handling and formatting date and time values.
By the end of this hands-on intermediate course, you’ll have mastered additional SQL techniques to extract and analyze the exact data you need, making it easier to turn raw data into actionable insights.
SQL proficiency equivalent to our SQL Level 1 course is required, including basic querying, fundamentals of filtering (WHERE, LIKE, BETWEEN), and inner JOINs.
