的Oracle SQL問題將多行插入表

Question

我使用下面的查詢將多個行插入表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; 

但我也跟着類似的問題一步STET，但我不知道爲什麼我收到此錯誤：

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

Answer 1

您需要爲每個插入指定into。這應該工作：

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

您可以用三個插入語句做到這一點：

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); 

或者使用union all一個聲明：

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; 

我沒有看到insert all的應用程序，因爲你要插入一個表。

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; 

它會插入100行具有相同的值
