Question

我正在尝试在我的数据库中插入新行。我需要插入155行。发生的事情是我正在添加基于现有帐户表的新用户。我有一个查询，列出了我需要添加到users表的新用户，但我不想输入155次插入。有更简单的方法吗？我已经看到插件中可以有多组“值”，但我不确定如何实现它。例如：

insert into tblUsers (State,City,Code)
Values ('IN','Indy',(select UserCode from tblAccounts where UserCode in(Select UserCode from tblAccounts where State = 'IN')))

我知道我的子查询将返回155个值，因此实际上不会在这里工作，有没有办法修改它以便它可以工作？

Answer 1

insert into tblUsers (State,City,Code)
   Select 'IN','Indy',  UserCode 
   from tblAccounts 
   where UserCode in (Select UserCode 
                     from tblAccounts 
                     where State = 'IN')

Answer 2

试试这个：

INSERT INTO tblUsers (State,City,Code)
SELECT 'IN','Indy', UserCode
FROM tblAccounts
WHERE UserCode IN
    (SELECT UserCode
     FROM tblAccounts
     WHERE State = 'IN')

或更好的简化（不需要子查询）：

INSERT INTO tblUsers (State,City,Code)
SELECT 'IN','Indy', UserCode
FROM tblAccounts
WHERE State = 'IN'

Answer 3

试试这个......

INSERT INTO tblUsers (State,City,Code)
SELECT 'IN','Indy', UserCode 
FROM tblAccounts 
WHERE UserCode IN (SELECT UserCode FROM tblAccounts WHERE State = 'IN')

Answer 4

查询：

INSERT INTO tblUsers (State,City,Code)
SELECT 'IN','Indy', UserCode
FROM tblAccounts
WHERE State = 'IN'

Answer 5

您只能从另一个表中插入，如下所示：

insert into tblUsers (State,City,Code)
SELECT * FROM table1
