有2个表 Table1 ，Table2 .
Table1的数据为
ID COL
1 A
1 B
2 B
2 A
2 C
3 A
3 C
3 B
4 A
4 C
Table2的数据为
ID COL
1 B
1 A
2 B
2 A
3 C
3 B
3 A
4 A
4 B
然后 将id相同的 但col不同的 选出来
那么结果是
ID TABLE1.COL TABLE2.COL
2 A,B,C A,B //col条数不同
4 A,C A,B //col值不同
那么这样SQL这样写 谢谢！

- SQL code
select a.id, a.c1, b.c2 from (select id, max(c1) c1 from (select id, wm_concat(col) over(partition by id order by col) c1 from (select id, col from t1 order by id, col)) group by id) a, (select id, max(c2) c2 from (select id, wm_concat(col) over(partition by id order by col) c2 from (select id, col from t2 order by id, col)) group by id) b where a.id = b.id and c1 <> c2;
