Types of explicit join conditions

Most join conditions are based on equality, and so are called equijoins. For example:

FROM Departments JOIN Employees
   ON Departments.DepartmentID = Employees.DepartmentID;

However, you do not have to use equality (=) in a join condition. You can use any search condition, such as conditions containing LIKE, SOUNDEX, BETWEEN, > (greater than), and != (not equal to).
