SQL Querying: Fundamentals

An “SQL Querying: Fundamentals” course is designed to introduce you to the foundational concepts and functionalities of SQL (Structured Query Language).This course is ideal for beginners with little to no prior experience with SQL or database querying.Understanding Relational Databases: You’ll gain a basic understanding of relational databases, including tables, columns, data types, primary and foreign keys, and how data is organized within them.The Core SQL Clauses: The course will focus on the fundamental SQL clauses used for data retrieval and manipulation: SELECT: This clause is used to specify the data you want to retrieve from a table.FROM: This clause specifies the table(s) from which you want to retrieve data.WHERE: This clause allows you to filter data based on specific conditions.ORDER BY: This clause sorts the retrieved data in a particular order (ascending or descending).GROUP BY: This clause groups data based on a specific column and allows you to perform aggregate functions (SUM, COUNT, AVG etc.) on the grouped data.Joining Tables: You’ll learn how to combine data from multiple tables using JOIN operations (e.g., INNER JOIN, LEFT JOIN) based on shared columns to create comprehensive datasets.Introduction to Functions: The course might introduce basic SQL functions for performing calculations and manipulations on data retrieved through queries (e.g., mathematical functions, string manipulation functions).
