Ditch Stackoverflow and get a comfortable grasp on the most important language in data and software engineering. Suitable for those who are brand new to SQL or engineers who have managed to squeak by with a limited knowledge of SQL (most of us, probably). Define database table schemas and write moderately complex queries to SELECT
/UPDATE
/DELETE
data, and perform actions like JOIN
s and aggregates.
What You'll Learn
- Defining tables from scratch with proper indexes and data types.
- Internalize everyday queries to select or modify data.
- Effectively designing tables to leverage foreign key relations.
- Execute and fully understand
JOIN
s. - Aggregate data to extract deeper meaning from SQL tables.
For those who...
- Are new to SQL or relational databases.
- Have mediocre knowledge of SQL and could benefit from filling the gaps.
- Have PHDs in statistics but think they can get by without knowing SQL.
