SQL Queries for Data Retrieval

SQL (Structured Query Language) is used to retrieve data from databases. SELECT: Specifies the columns to retrieve. FROM: Specifies the table(s) from which to retrieve data. WHERE: Filters data based on conditions. JOIN: Combines data from multiple tables. GROUP BY: Groups rows with the same values. HAVING: Filters the results of a GROUP BY clause. ORDER BY: Sorts the retrieved data. LIMIT: Limits the number of rows returned. By combining these commands and clauses, you can create complex SQL queries to retrieve specific subsets of data from your database.

A `SELECT` statement is used to retrieve specific columns based on given conditions. ---
