Question

我给两个参数begindate和enddate

示例

@begindate = '2012-01-01'
@endate = '2013-01-01'

结果为

begindate             enddate
2012-01-01 00:00:00   2012-01-01 00:10:00
2012-01-01 00:10:00   2012-01-01 00:20:00
2012-01-01 00:20:00   2012-01-01 00:30:00

像这样

我写这段代码

create table Test
(
a datetime,
b datetime 
)

DECLARE @BeginDate date = '2012-01-01'

DECLARE @EndDate date = '2012-12-31'

DECLARE @beginValue int = 1

DECLARE @count int =  DATEDIFF ( day , '2012-01-01' , '2012-12-31' )
DECLARE @dayHours INT = 0 
DECLARE @dayHoursLimit INT = 23
DECLARE @Minute INT = 0
DECLARE @MinuteLimit INT= 50
DECLARE @CountOfMinute INT =10

while @beginValue <= @count 
begin

    SET @BeginDate=  DATEADD(DAY,1, @BeginDate);

    WHILE @dayHours <= @dayHoursLimit
    BEGIN
        WHILE @Minute <= @MinuteLimit
        BEGIN
            insert into TEST

            SELECT CAST(CAST(@BeginDate AS VARCHAR(10)) +' '+CAST(@dayHours AS varchar(2)) +':'+CAST (@Minute AS varchar(2)) AS datetime) as a , 
            CAST(CAST(@BeginDate AS VARCHAR(10)) +' '+CAST(@dayHours AS varchar(2)) +':'+CAST (@Minute +@CountOfMinute AS varchar(2)) AS datetime) as b
            0 AS B
            SET @Minute = @Minute + @CountOfMinute      
         END
    SET @Minute = 0
    SET @dayHours = @dayHours +1
END
    SET @dayHours = 0
    SET @beginValue = @beginValue +1
END

您希望在@BeginDate和@EndDate之间每隔10分钟生成一行。如果是这样，请使用递归CTE：

DECLARE @BeginDate  datetime = '2012-01-01'
DECLARE @EndDate    datetime = '2013-01-01'

;WITH cte AS (
    SELECT @BeginDate AS BeginDate,
            DATEADD(minute, 10, @BeginDate) AS EndDate
    UNION ALL
    SELECT DATEADD(minute, 10, BeginDate),
            DATEADD(minute, 20, BeginDate)
    FROM cte
    WHERE BeginDate < DATEADD(minute,-10,@EndDate)
)

SELECT * FROM cte
OPTION (MAXRECURSION 0)
