データベースビューより、4つのテーブルを結合したい
設定、where句の記述がわからない(Where句が理解できていないです。)
対象テーブル
task、incident、change_request、problem
(2つはできた。task、incident)
4つは? できるのか?

Got it, so you can create a database view like this,

o join all the four you may need to create 3 records in view tables related records for a database view record. Keeping task as base you can join with other table.
task with incident : task_sys_id=incident_sys_id
task with problem: task_sys_id=problem_sys_id
task with change : task_sys_id = change_sys_id
