SQL Dialect Cheat Sheet

Side-by-side syntax across BigQuery, Postgres, SQL Server, MySQL, and Snowflake

If you write SQL for data analysis, reporting, or dashboard development, you know how frustrating it can be to switch between platforms.

The same logic that works in Postgres might break in BigQuery. A simple date function in SQL Server might throw an error in Snowflake.

This SQL Dialect Cheat Sheet gives you a side-by-side comparison of the syntax that changes between tools, so you can spend less time Googling and more time getting the results you need.

It’s built for data analysts, engineers, and BI professionals who work across systems or are prepping for interviews with unfamiliar SQL stacks.

What’s included:

✅ SQL Dialect Cheat Sheet (3-page Digital PDF)

• Side-by-side syntax for BigQuery, Postgres, MySQL, SQL Server, and Snowflake.
• Grouped by function type: string, date, logic, filters, casting, and more.
• Output differences, common pitfalls, and safe syntax defaults.
• Clean format (PDF) built for quick lookups.
• Includes how to convert between date/datetime, use DATEADD, DATEDIFF, CONCAT_WS, CASE, window functions, and more.
• Ideal for job switchers, cross-platform teams, or anyone tired of re-Googling everything.
  

Sample of what you'll find in the cheat sheet

Use this guide to:

• Compare syntax when switching platforms.
• Fix broken queries after tool migrations.
• Speed up onboarding on new SQL stacks.
• Study for cross-platform technical interviews.
• Understand where logic needs to change (and where it doesn’t).
  

I hope it helps you write better SQL, faster, no matter what platform you're working in.
