Learn T-SQL With Erik: SELECT FROM WHERE?

Description:
In this video, I dive into the fundamentals of writing SQL queries by focusing on the basics of selecting from a table using a WHERE clause. As part of my Learn T-SQL with Erik course, which is currently in its early stages, I provide an essential introduction to query construction and execution. I explain how your initial query formulation differs from how SQL Server interprets it during execution, emphasizing key concepts like the order of operations (FROM, WHERE, GROUP BY, etc.) and why certain elements are not accessible across different parts of a query. This teaser gives viewers a taste of what's to come in the full course, where we delve deeper into crafting efficient and accurate queries that can handle various database scenarios.
