Snowflake Automate Data Load & Validation in Single Step | Real-Time Interview Scenario
Learn how to load and validate data in Snowflake — in one step!
In this video, I walk you through a real-world scenario where we automate the process of loading data from a stage (like S3) and performing basic validations (like null and duplicate checks) — all using a single stored procedure in Snowflake.
🚀 What you'll learn:
How to automate data load + quality checks in one go
Creating a temporary staging table
Performing NULL and DUPLICATE validations
Inserting clean data into your main table
Logging results in an audit table
📌 Use Case:
Imagine your client gives you a complex CSV or JSON file and expects clean data in the Silver Layer. Doing validation after loading causes rework. This procedure solves that by catching issues upfront.
💡 Bonus:
This solution can be extended to support custom validations and parameterized for different tables and stages.
