如何连接 2 个表以接收所需的所有数据

Question

我有 2 个问题：

/*+ ETLM
{
  depend:{
    replace:[
      {
        name:"table_1"
      }
    ]
  }
}
*/
SELECT 

case_id,
x,
x,
x,
x,
x

FROM table.1


WHERE resolved_date between TO_DATE ('2020/01/01', 'YYYY/MM/DD') and to_date('2020/12/31','YYYY/MM/DD')
AND ASSIGNED_TO_GROUP IN ('First Group')

和

/*+ ETLM
{
  depend:{
    replace:[
      {
      name:"table_2"
      }
    ]
  }
}
*/



SELECT

x,
x,
x,
case_id,
x,
x


FROM table_2

WHERE create_date between TO_DATE ('2020/01/01', 'YYYY/MM/DD') and to_date('2020/12/31','YYYY/MM/DD')

所以基本上我需要表中的所有信息，case_id 是 table_1 上的主键。我怎样才能加入他们以接收所有数据并仅使用 table_1?

中的 WHERE's

PS：表格是在 redshift

上启用的频谱

我试过了

Select
x
x
x
FROM table_1 

JOIN table_2 ON table_1.case_id = table_2.case_id
Select 
x
x
x
FROM table_2

Where table_1.resolved_date between ...
AND table_1.assigned_group...

但是我在第二个 SELECT 语句中似乎出错了

Answer 1

Select
table_1.x,
table_1.x,
table_1.x,
table_2.x,
table_2.x,
table_2.x
FROM table_1 

JOIN table_2 ON table_1.case_id = table_2.case_id

Where table_1.resolved_date between ...
AND table_1.assigned_group...
