Visualizing SQL Queries

A mental model can help visualize how SQL queries are executed. Conceptually, SQL statements execute in this sequence:

1. FROM: Tables are identified and joined to create the initial dataset.
2. WHERE: Filters are applied to the initial dataset based on specified criteria.
3. GROUP BY: The filtered rows are grouped according to the specified columns.
4. HAVING: Additional filters are applied to the grouped rows based on aggregate criteria.
5. SELECT: Specific columns are chosen from the resultant dataset for the output.
6. ORDER BY: The output rows are sorted by the specified columns in ascending or descending order.
7. LIMIT: The number of rows in the output is restricted.

While the actual execution plan may vary due to query optimization, this mental model provides a valuable framework for understanding SQL logic.
