如何从 SQL Server 中删除转换失败的日期/时间错误？

如何解决如何从 SQL Server 中删除转换失败的日期/时间错误？

我写了一个程序，它给了我这个错误

Msg 241,Level 16,State 1,Procedure SumByDay,Line 7 [Batch Start Line 36]
从字符串转换日期和/或时间时转换失败。

这是流程

ALTER PROCEDURE SumByDay (@IN_forDate AS DATE,@IN_sensID INT)
AS
BEGIN
    DECLARE @timeFrom DATETIME2;
    DECLARE @timeto DATETIME2;
    DECLARE @rowCount INT = 0; -- sqlInes DEMO *** statement affected rows

    SET @timeFrom = concat(CAST(@IN_forDate AS DATETIME2),CAST('00:00:00' AS TIME)); -- start of the day
    SET @timeto = concat(CAST(@IN_forDate AS DATETIME2),CAST('23:59:59.999999' AS TIME)); -- end of the day
       
    DELETE FROM TrafficPerDay 
    WHERE TrafficPerDay.sensorID = @IN_sensID 
      AND TrafficPerDay.sDay = @IN_forDate; -- sqlInes DEMO *** sts,delete it,and recreate with new data
       
    INSERT INTO TrafficPerDay(sensorID,sDay,Motorcycle,Car,Van,Bus,Coach,Truck,ArticulatedTruck,Semitruck,Pedestrian,[UnkNown],sTotal)
        (SELECT 
             t.sensorID,@IN_forDate AS 'sDay',COUNT(CASE WHEN t.classId = 1 THEN 'id' END) 'Motorcycle',COUNT(CASE WHEN t.classId = 2 THEN 'id' END) 'Car',COUNT(CASE WHEN t.classId = 3 THEN 'id' END) 'Van',COUNT(CASE WHEN t.classId = 4 THEN 'id' END) 'Bus',COUNT(CASE WHEN t.classId = 5 THEN 'id' END) 'Coach',COUNT(CASE WHEN t.classId = 6 THEN 'id' END) 'Truck',COUNT(CASE WHEN t.classId = 7 THEN 'id' END) 'ArticulatedTruck',COUNT(CASE WHEN t.classId = 8 THEN 'id' END) 'Semitruck',COUNT(CASE WHEN t.classId = 9 THEN 'id' END) 'Pedestrian',COUNT(CASE WHEN t.classId = 0 THEN 'id' END) 'UnkNown',COUNT(t.id) AS 'sTotal'
         FROM 
             TrafficRecord t
         WHERE 
             t.time BETWEEN @timeFrom AND @timeto AND t.sensorId = @IN_sensID 
         GROUP BY t.sensorID,t.time );
        
    -- sqlInes LICENSE FOR EVALUATION USE ONLY
    SELECT @rowCount = @@ROWCOUNT

    IF (@rowCount = 0) 
    BEGIN  -- sqlInes DEMO *** ed,insert zeros
        INSERT INTO TrafficPerDay(sensorID,sTotal)
        VALUES (@IN_sensID,@IN_forDate,0);
    END  
END

我正在执行这样的程序

exec SumByDay @IN_forDate = '2020-11-04',@IN_sensID = 1;

解决方法

问题是你在第 7 行的连接，正如错误告诉你的那样，但你不需要那个。使用 >= 和 < 逻辑代替 BETWEEN：

ALTER PROCEDURE SumByDay (@IN_forDate AS date,@IN_sensID int)
AS
BEGIN
    --DECLARE @timeFrom datetime2; -- No need for these
    --DECLARE @timeTo datetime2; -- No need for these
    DECLARE @rowCount int = 0; -- SQLINES DEMO *** statement affected rows
    --SET @timeFrom = CONCAT(CAST(@IN_forDate AS datetime2),CAST('00:00:00' AS time)); -- start of the day -- No need for these
    --SET @timeTo = CONCAT(CAST(@IN_forDate AS datetime2),CAST('23:59:59.999999' AS time)); -- end of the day -- No need for these

    DELETE FROM TrafficPerDay
    WHERE TrafficPerDay.sensorID = @IN_sensID
      AND TrafficPerDay.sDay = @IN_forDate; -- SQLINES DEMO ***
    --sts,delete it,and recreate with new data

    INSERT INTO TrafficPerDay (sensorID,sDay,Motorcycle,Car,Van,Bus,Coach,Truck,ArticulatedTruck,Semitruck,Pedestrian,[Unknown],sTotal)
    (SELECT t.sensorID,@IN_forDate AS sDay,COUNT(CASE WHEN t.classId = 1 THEN 'id' END) AS Motorcycle,COUNT(CASE WHEN t.classId = 2 THEN 'id' END) AS Car,COUNT(CASE WHEN t.classId = 3 THEN 'id' END) AS Van,COUNT(CASE WHEN t.classId = 4 THEN 'id' END) AS Bus,COUNT(CASE WHEN t.classId = 5 THEN 'id' END) AS Coach,COUNT(CASE WHEN t.classId = 6 THEN 'id' END) AS Truck,COUNT(CASE WHEN t.classId = 7 THEN 'id' END) AS ArticulatedTruck,COUNT(CASE WHEN t.classId = 8 THEN 'id' END) AS Semitruck,COUNT(CASE WHEN t.classId = 9 THEN 'id' END) AS Pedestrian,COUNT(CASE WHEN t.classId = 0 THEN 'id' END) AS Unknown,COUNT(t.id) AS sTotal
     FROM TrafficRecord t
     WHERE t.time >= @IN_forDate
       AND t.time < DATEADD(DAY,1,@IN_forDate)
       AND t.sensorId = @IN_sensID
     GROUP BY t.sensorID,t.time); --Should this be CONVERT(date,t.time),--or considering that this is for a single day,removed?
                       --If not,then simply t.time = @IN_forDate would work

    -- SQLINES LICENSE FOR EVALUATION USE ONLY
    SELECT @rowCount = @@ROWCOUNT;
    IF (@rowCount = 0)
    BEGIN -- SQLINES DEMO *** ed,insert zeros
        INSERT INTO TrafficPerDay (sensorID,sTotal)
        VALUES (@IN_sensID,@IN_forDate,0);
    END;
END;

您设置的 datetime2 值不正确。

通过将时间连接到您已经转换为 datetime2 的日期，您试图然后将 2021-03-18 00:00:00.000000000:00:00.0000000 之类的日期分配给 @timeFrom - 显然不正确。

只需做@timeFrom=Concat(@IN_forDate,' 00:00:00')等
