从oracle PL \ SQL中的tableA插入tableB中缺少的行

Question

我想在tableB中插入缺少表A的行 当我在oracle上编写下面的代码时，会抛出错误＆＃34; ORA-00913：值太多了 00913. 00000 - ＆＃34;太多的价值观＆＃34;

请建议我正确的语法：

insert into tableB 
Select * from 
(Select * 
from tableA A
left join tableB B
on a.id = B.id
and a.year = b.year
where (a.id is null or a.year is null) )A;

Answer 1

ISNULL条件需要在tableB的列上，您只需要选择tableA列值。

insert into tableB 
Select * from 
(Select A.* 
from tableA A
left join tableB B
on a.id = B.id
and a.year = b.year
where (b.id is null or b.year is null) )A;
