sql - 两个表的平面连接

Question

对于这两个表:

CREATE TABLE TEST1 ( ID  INTEGER ,key  VARCHAR(50),VALUE1 VARCHAR(50));
CREATE TABLE TEST2 ( ID  INTEGER ,key  VARCHAR(50),VALUE2 VARCHAR(50));

表 1:

130,    'HANSEN',   'STREET1'
130,    'HANSEN',   'STREET2'
130,    'HANSEN',   'STREET3'
120,    'HANSEN',   'STREET5'
120,    'HANSEN',   'STREET6'

表 2:

130,    'HANSEN',   'ZIP1'
130,    'HANSEN',   'ZIP2'
130,    'HANSEN',   'ZIP3'
120,    'HANSEN',   'ZIP4'
120,    'HANSEN',   'ZIP5'

是否有可能得到如下输出:

130,    'HANSEN',   'ZIP1','STREET1'
130,    'HANSEN',   'ZIP2','STREET2'
130,    'HANSEN',   'ZIP3','STREET3'
120,    'HANSEN',   'ZIP4','STREET5'
120,    'HANSEN',   'ZIP5','STREET6'

尝试在 id,key 上使用 inner join，但我得到了笛卡尔积
感谢您的帮助。

帮助脚本(如果有人愿意测试的话):

DROP TABLE TEST1;
DROP TABLE TEST2;

CREATE TABLE TEST1 ( ID  INTEGER ,key  VARCHAR(50),VALUE1 VARCHAR(50));
CREATE TABLE TEST2 ( ID  INTEGER ,key  VARCHAR(50),VALUE2 VARCHAR(50));

INSERT INTO TEST1 VALUES (130,  'HANSEN',   'STREET1');
INSERT INTO TEST1 VALUES (130,  'HANSEN',   'STREET2');
INSERT INTO TEST1 VALUES (130,  'HANSEN',   'STREET3');
INSERT INTO TEST1 VALUES (120,  'HANSEN',   'STREET5');
INSERT INTO TEST1 VALUES (120,  'HANSEN',   'STREET6');

INSERT INTO TEST2 VALUES (130,  'HANSEN',   'ZIP1');
INSERT INTO TEST2 VALUES (130,  'HANSEN',   'ZIP2');
INSERT INTO TEST2 VALUES (130,  'HANSEN',   'ZIP3');
INSERT INTO TEST2 VALUES (120,  'HANSEN',   'ZIP4');
INSERT INTO TEST2 VALUES (120,  'HANSEN',   'ZIP5');

应该这样做:

with t1 as (
    select id, 
           key, 
           value1,
           row_number() over (partition by id order by key, value1) as rn
    from test1
), 
t2 as (
    select id, 
           key, 
           value2,
           row_number() over (partition by id order by key, value2) as rn
    from test2
)
select t1.id, 
       t2.key, 
       t2.value2||','||t1.value1
from t1
  join t2 on t1.id = t2.id and t1.key = t2.key and t1.rn = t2.rn
order by 1 desc, 3 asc
