Аннотация

This article discusses the creation of simple queries for data manipulation, focusing on the essential techniques for interacting with databases. Data manipulation involves tasks like retrieving, updating, and deleting data, all of which are achieved through SQL (Structured Query Language) queries. The article introduces key SQL operations, such as the SELECT, INSERT, UPDATE, and DELETE statements, and explains their usage with practical examples. It also covers the application of aggregation functions like COUNT, SUM, AVG, and how to use JOINs for combining data from multiple tables. This foundational knowledge of SQL queries is crucial for those working with databases to analyze and transform raw data into actionable insights.
