Querying Snowflake with SQL
Description
In the training "Querying Snowflake SQL for data analysts" we cover Snowflake SQL, the query and design language for Snowflake. We focus on making analyzes in SQL, and preparing, linking and enriching datasets for use within other analysis tools. From the broad experience of data analysis, the trainer shares examples, and has numerous "puzzles" ready that help to really understand SQL better. We conclude with the very powerful concepts of windowing , ranking , subqueries and CTEs (Common Table Expressions) . As a data analyst you can efficiently perform and solve all kinds of analyzes with this.
This course is aimed at data analysts, data engineers and data scientists who want to support their work in Snowflake by leveraging the power of SQL for advanced data analytics.
After this three-day training you will be able to:
- Use SnowSQL
- Write SELECT statements to retrieve columns from one or more tables
- Join tables using JOIN statements (and really understand what's happening)
- Sort and filter data
- Use built-in SQL functions to analyze data
- Grouping and aggregating (summarizing) datasets
- Structure complex SQL queries with Common Table Expressions
- Sort and use Windowing and Ranking functions
- Transform datasets using Pivot and Unpivot
