cds view join和association

1：创建两张表：ztt_teacher01 和ztt_teacher02 用于 cds view中的join和association

2：创建两个cds view：ztt_teacher01_id_name和 ztt_teacher02_id_salary

3： 在ztt_teacher01_id_name 中使用连接对数据表进行查询

@AbapCatalog.sqlViewName: 'TEACHER01'
@AbapCatalog.compiler.compareFilter: true
@AbapCatalog.preserveKey: true
@AccessControl.authorizationCheck: #CHECK
@EndUserText.label: 'teacher table have id,name field'
define view ztt_teacher01_id_name as select from ztt_teacher01 as t01 left outer join ztt_teacher02 as t02 on t01.id = t01.id {
  t01.id,
  name,
  salary
}

结果如下：
