Week 5: Articles

The articles for this week cover SQL join operations between two and three tables. You cover cross joins, inner joins, and outer joins first, and then you cover joins between two or more copies of a table and filtered cross joins. Filtered cross joins are also known as non-equijoins and they use inequality operators or range comparisons where the value is between two values.
