The Complete Guide to Querying Data with Snowflake

What you'll learn
Snowflake Semi-Structured Data (JSON and Parquet Files) Queries
Snowflake Windowing Queries
Snowflake Data Generation Queries
Snowflake Snowsight (Snowflakes Next Generation Worksheet Replacement)
Snowflake Information Schema and Account Usage Queries
Snowflake Common Table Expression and Connect By Queries
Snowflake Pivot and Unpivot Queries
Snowflake Query Performance Monitoring
Requirements
Some basic understand of Snowflake and SQL would be very helpful
Description
SQL is the most used query language in the world and Snowflake is quickly becoming the most used cloud data platform in the world.​

There are, of course, other query languages for different types of databases, such as NoSQL databases but SQL remain the standard and Snowflake's SQL implementation is full ANSI SQL compliant.Snowflake's cloud data platform features a data warehouse / data lake architecture that supports the most common standardized version of SQL (ANSI) for extremely powerful relational database querying. Snowflake can also be used as a data lake replacement, or supplement, because it can also aggregate semi-structured data such as JSON and Parquet, with structured data in a SQL format. Snowflake simplifies access to JSON data and allows users to combine it with structured data. In this course we cover many query techniques such as Windowing functions, Common Table Expressions (CTEs) and Connect By, generating data, travel queries, working with dates and s, pivot and unpivot queries, regular expression queries and many other types of queries.We demonstrate how to perform query performance monitoring. We also spend a significant amount of demonstrating how Snowflake can be used to query semi-structured data such as JSON and Parquet files.When you finish part 1 of this course you will have a solid foundation for perfog numerous types of Snowflake queries.
