This article provides an in-depth exploration of using INNER JOIN in SQL to query employee names along with their corresponding manager names. Through a typical corporate employee database case study, it explains the working principles of inner joins, common errors, and correction methods. The article begins by introducing the database table structure design, including primary and foreign key constraints in the EMPLOYEES table, followed by concrete data insertion examples to illustrate actual data relationships.
