Sql 如何从开始日期开始以5分钟的间隔生成日期时间数据并填充该列？

生成以下输出，其中时间戳从开始日期开始，间隔为5分钟，将在结束日期结束，并且placeID需要是随机的（介于1到4之间），使用SQL server

--建立数据库；数据库名称PARKINGDATA以便于更好地理解

Create database parkingdata;

use parkingdata;

CREATE Table marketplace
(

   MarketPlaceId nvarchar,
   DateTimeStamp datetime,

)

--drop table marketplace;

SELECT * from marketplace;




Declare @RandomMarketPlaceID int;
Declare @RandomDateTimeStamp datetime;

Declare @IdLowerLimitNumber int;
Declare @IdUpperLimitNumber int;

Set @IdLowerLimitNumber = 1
Set @IdUpperLimitNumber = 4



DECLARE @start DATETIME = '2015-01-01 00:00:00';
DECLARE @end DATETIME = '2015-03-05 00:00:00';
DECLARE @minuteInterval INT = 5;

DECLARE @countNum INT = DATEDIFF(MINUTE, @start, @end) / @minuteInterval + 1;


Declare @count int
Set @count = 1

While @count <= 20000
Begin 

    Select @RandomMarketPlaceID = Round(((@IdUpperLimitNumber - @IdLowerLimitNumber) * Rand()) + 
    @IdLowerLimitNumber, 0)

    WITH N1 AS (SELECT N = 1 UNION ALL SELECT 1), -- 2
         N2 AS (SELECT N = 1 FROM N1 CROSS JOIN N1 AS N), -- 4
         N3 AS (SELECT N = 1 FROM N2 CROSS JOIN N2 AS N), -- 16
         N4 AS (SELECT N = 1 FROM N3 CROSS JOIN N3 AS N), -- 256
         N5 AS (SELECT N = 1 FROM N4 CROSS JOIN N4 AS N),  -- 65536
         Numbers AS (SELECT Number = ROW_NUMBER() OVER (ORDER BY (SELECT NULL)) FROM N5)
    SELECT @RandomDateTimeStamp= DATEADD(MINUTE, @minuteInterval * (Numbers.Number - 1), @start)
        FROM Numbers
        WHERE Numbers.Number <= @countNum;


    Insert Into marketplace values (@RandomMarketPlaceID, @RandomDateTimeStamp)

    Print @count
    Set @count = @count + 1
End


Required OUTPUT Should be:

MarketPlaceID      DateTimestamp
3                  2015-01-01 00:00:00
2                  2015-01-01 00:05:00
4                  2015-01-01 00:10:00
1                  2015-01-01 00:15:00
2                  2015-01-01 00:20:00
.
.
.
.till the end date.

创建数据库parkingdata；
使用停车数据；
创建表格市场
(
MarketPlaceId nvarchar，
日期时间戳日期时间，
)
--升降台市场；
从市场中选择*；
声明@RandomMarketPlaceID int；
声明@randomDateTimestampDateTime；
声明@IdLowerLimitNumber int；
声明@IdUpperLimitNumber int；
设置@IdLowerLimitNumber=1
设置@IdUpperLimitNumber=4
声明@start DATETIME='2015-01-01 00:00:00'；
声明@end DATETIME='2015-03-05 00:00:00'；
声明@minuteInterval INT=5；
声明@countNum INT=DATEDIFF（分钟、@start、@end）/@minuteInterval+1；
声明@countint
设置@count=1
当@count时，我们真的需要表
Number
，因为我们可以通过在循环中使用
@countNum
来实现所需的结果吗？
请尝试以下操作：

While @count <= @countNum
Begin 

    Select @RandomMarketPlaceID = Round(((@IdUpperLimitNumber - @IdLowerLimitNumber) * Rand()) + @IdLowerLimitNumber, 0)

    SELECT @RandomDateTimeStamp = DATEADD(MINUTE, @minuteInterval * @count, @start);

    Insert Into marketplace values (@RandomMarketPlaceID, @RandomDateTimeStamp)

    Set @count = @count + 1
End

While@count您使用的是MySQL还是MS SQL Server？我使用的是SQL Server。@AnirbanSom gr8，如果这有助于解决问题，您可以接受答案。
