Building a Strong Foundation in SQL Query Writing
What you'll learn
Use of Scalar functions to manipulate or compute values for individual rows of a result set
Use of Aggregation Functions allowing you to summarize and compute statistics on data, providing valuable insights into trends and patterns.
Joins to combine data from multiple tables, enabling to perform more complex queries and gain insights from related datasets.
Subqueries as a means of filtering data based on the results of another query or performing calculations
Requirements
A basic understanding of mathematical concepts like arithmetic, comparisons, and logical operations can be beneficial when constructing SQL queries involving calculations or conditional statements.
