Question

我有一张桌子和一张桌子

Table d
--------

id number
1   23
1   24
1   25
2   22
2   23

我需要插入表格f

INSERT INTO f 
 SELECT max(f)+1,
 (select d.number from d where number = 1),
 FROM f

表f需要

id   d.id      d.number
1     1         23
2     1         24
3     1         25

我必须选择3行并使用一个选择查询插入到该表中。

Answer 1

您可以使用以下sql查询，

{{1}}

Answer 2

您只需在子查询和外部查询中指定正确的列名。

INSERT INTO f VALUES (id,number) (SELECT id,number FROM d WHERE id = 1)

并且您无法在f id和number中将d和d.id中的d.number和INSERT INTO f VALUES ( id, idNew, number ) SELECT ROW_NUMBER() OVER(ORDER BY Id) AS RowNumber, d.id, d.number FROM d WHERE id = 1称为外键可以＆＃39 ; t设置在非主键列上。

Answer 3

首先，让我们设置您的表格定义：http://sqlfiddle.com/#!6/6b644c/1

create table d (id int, num int);
create table f (id int, d_id int, d_num int);

insert into d (id, num) values
(1,23),
(1,24),
(1,25),
(2,22),
(2,23);

然后，这应该可以获得您指定的结果。

insert into f (id, d_id, d_num) 
  select row_number() over (order by num), d.id, d.num
  from d
  where d.id = 1;

如果您想为每个现有的id计数器启动新的partition by计数器，请添加where子句并将insert into f (id, d_id, d_num) select row_number() over (partition by id order by num), d.id, d.num from d这样的内容保留为：var dir = process.env.PWD; options["fName"] = "./test.apk"; {3}}

SELECT A.[CallID]
FROM dbo.[Calls] A WITH(NOLOCK)
INNER JOIN [dbo].[Issues] B WITH(NOLOCK) ON A.[CallID] = B.[CallID]
WHERE A.[AddedByUserID] = @UserID
  AND A.[EndTime] IS NULL
  AND DATEDIFF(d,A.AddedOn,GETDATE()) <= 1

从单个insert和select语句中插入多行
