Question

我希望在Oracle中的表中插入多行。但它让我很困惑：我不能用

insert into pager (PAG_ID,PAG_PARENT,PAG_NAME,PAG_ACTIVE)
          (select seq_paper.nextval,'Multi 8000',1 from dual
 union all select seq_paper.nextval,'Multi 8001',1 from dual)

因为table1需要是新的。我需要在存在的table1中插入一些行。

我也不能用

Restrictions on Sequence Values You cannot use CURRVAL and NEXTVAL in the  
following constructs:  
■ A SELECT statement that is combined with another SELECT statement with the  
UNION, INTERSECT, or MINUS set operator ;
...and other constructs

因为oracle告诉我：

{{1}}

Answer 1

您可以对select进行修改，以便nextval不在union。

结果如下：

insert into pager (PAG_ID,PAG_PARENT,PAG_NAME,PAG_ACTIVE) 
    select seq_paper.nextval, NULL, a, b from 
        (select 'Multi 8000' a, 1 b from dual 
         union all 
         select seq_paper.nextval,'Multi 8001',1 from dual)

Answer 2

使用nextval一次并在子查询中创建数据：

800px

如何在Oracle中多行插入序列？
