Difference between And clause along with on and Where clause when used with left join in SQL Server - CodeProject

Suppose we have two tables Departments (deptId, deptName) and Employees (empID, DeptID, EmpName, Salary) and deptiD is the foreign key of the department table. When the On clause is used in an outer join, the outer table will have no effect on this On clause and all rows from the outer table will be returned and the On clause determines which rows of the subordinate table joins to the outer table

Mullins CASE expressions are often over-looked but can be extremely useful to change very complex query requirements into simpler, and sometimes more efficient SQL statements. It provides a quick way of transforming normalized data structures into the more common denormalized formats that most business users are accustomed to viewing on reports

notation, or you can use CASE WHEN expr THEN ..., but your simple CASE WHEN NULL THEN notation will never evaluate the THEN because NULL will always evaluate to UNKNOWN, not TRUE
