About this course
SQL becomes easier to approach when a table is something you can inspect and question. Oscar Valles begins with connecting to a database and understanding tables, then introduces statements for creating records and retrieving the rows you need.
The course progresses through SELECT, counting, filtering, comparisons, AND and OR, sorting, pattern matching and simple calculations. Several exercise-solution lessons give learners opportunities to compare their approach with the instructor’s explanation. The examples include a movie-information dataset.

A computer and internet connection are the listed requirements. The course supplies a connection setup for a shared practice database and notes that the connection details in the videos were replaced. Use the current instructions inside the course; this review has not connected to that database or confirmed its present availability.
This is the first part of a beginner sequence. The instructor explicitly leaves joins for a later course, so they are not included in the scope described here. Practice table-creation and deletion commands only in the intended learning environment, and keep real business data separate from shared training systems.
