Question

我使用以下查询将多行插入表my_employee：

insert all into 
  my_employee (id, last_name, first_name, userid, salary) values (&id, '&last_name', '&firstname', '&userid', &salary)
  my_employee (id, last_name, first_name, userid, salary) values (&id, '&last_name', '&firstname', '&userid', &salary)
  my_employee (id, last_name, first_name, userid, salary) values (&id, '&last_name', '&firstname', '&userid', &salary)
select * from DUAL;

然而我一步一步地跟着类似的问题，但我不知道为什么我会收到这个错误：

Erreur SQL : ORA-00928: missing SELECT keyword
00928. 00000 -  "missing SELECT keyword"

Answer 1

您需要为每个插入指定into。这应该有效：

insert all 
  into my_employee (id, last_name, first_name, userid, salary) values (&id, '&last_name', '&firstname', '&userid', &salary)
  into my_employee (id, last_name, first_name, userid, salary) values (&id, '&last_name', '&firstname', '&userid', &salary)
  into my_employee (id, last_name, first_name, userid, salary) values (&id, '&last_name', '&firstname', '&userid', &salary)
select * from DUAL;

Answer 2

您可以使用三个插入语句执行此操作：

insert into my_employee (id, last_name, first_name, userid, salary)
    values (&id, '&last_name', '&firstname', '&userid', &salary);

insert into my_employee (id, last_name, first_name, userid, salary)
    values (&id, '&last_name', '&firstname', '&userid', &salary);

insert into my_employee (id, last_name, first_name, userid, salary)
    values (&id, '&last_name', '&firstname', '&userid', &salary);

或使用union all的一个声明：

insert into my_employee (id, last_name, first_name, userid, salary)
    select &id, '&last_name', '&firstname', '&userid', &salary
    from dual union all
    select &id, '&last_name', '&firstname', '&userid', &salary
    from dual union all
    select &id, '&last_name', '&firstname', '&userid', &salary;

我没有看到insert all的申请，因为你想插入一张表。

Answer 3

在MSSQL中

insert into my_employee (id, last_name, first_name, userid, salary)
    values (&id, '&last_name', '&firstname', '&userid', &salary)
go 100;

它将插入具有相同值的100行
