While working as a backend developer, I noticed I repeatedly used the same SQL queries for joins, aggregations, pagination, and duplicate detection.
So I created a small cheat sheet with 30 SQL queries that backend developers commonly use.
It includes practical examples for:
• JOIN queries
• Aggregations
• Filtering
• Pagination
• Finding duplicates
I turned it into a small PDF for quick reference.
If anyone wants to check it out:
