SQL Server : 将 Datetime2 转换为时间(7)

Question

我正在尝试将datetime2 与time(7) 进行比较

我需要帮助转换datatime2。

这是我尝试过的：

DECLARE @PracticeStartTime time(7)
DECLARE @PracticeEndTime time(7)

SET @PracticeStartTime = (
    SELECT PBH.StartTime
    FROM PracticePractitioner AS PP WITH (NOLOCK)
    LEFT JOIN PracticeBusinessHours AS PBH WITH (NOLOCK)
        ON PBH.PracticeId = PP.PracticeId
    WHERE PP.PractitionerId = @PractitionerId
    )
SET @PracticeEndTime = (
    SELECT PBH.EndTime
    FROM PracticePractitioner AS PP WITH (NOLOCK)
    LEFT JOIN PracticeBusinessHours AS PBH WITH (NOLOCK)
        ON PBH.PracticeId = PP.PracticeId
    WHERE PP.PractitionerId = @PractitionerId
    )

IF (
    (
        CONVERT(@ScheduledStart AS TIME) BETWEEN @PracticeStartTime
            AND @PracticeEndTime
        )
    AND (
        CONVERT(@ScheduledEnd AS TIME) BETWEEN @PracticeStartTime
            AND @PracticeEndTime
        )
    )
BEGIN
    PRINT 'Time within practice hours';
END
ELSE
BEGIN
    RETURN - 1
END

Answer 1

您的语法已关闭。

我会使用CAST

cast(@ScheduledStart as time(7))

你可以使用CONVERT

convert(time(7), @ScheduledStart)
