Question

我有两列包含HH:MM格式的时间。例如，column1的值为149：10，column2的值为110：20。

我想添加两列，我希望输出结果的格式为HH:MM

Answer 1

由于给定的值无法存储到TIME数据类型中，因此会抛出错误，如下所示：

DECLARE @TimeStamp1 AS TIME = '149:10'; SELECT @TimeStamp1;

因此，您的输入可能是varchar。

我尝试了一种给定相同数据的方法：

DECLARE @TimeStamp1 AS VARCHAR(20) = '149:40'; 
DECLARE @TimeStamp2 AS VARCHAR(20) = '110:40';

SELECT  CAST(
            CAST(PARSENAME(REPLACE(@TimeStamp1, ':', '.'), 2) AS INT) + 
            CAST(PARSENAME(REPLACE(@TimeStamp2, ':', '.'), 2) AS INT) + 
            ((CAST(PARSENAME(REPLACE(@TimeStamp1, ':', '.'), 1) AS INT) + CAST(PARSENAME(REPLACE(@TimeStamp2, ':', '.'), 1) AS INT)) / 60) AS VARCHAR (20)) 
        + ':' + 
        CAST((
            (CAST(PARSENAME(REPLACE(@TimeStamp1, ':', '.'), 1) AS INT) + 
            CAST(PARSENAME(REPLACE(@TimeStamp2, ':', '.'), 1) AS INT)) % 60) AS VARCHAR (20)) AS Result;

 Result
 --------
 260:20

Answer 2

以下查询应该有效

declare @s1 varchar(max), @s2 varchar(max)
select @s1='149:50',@s2='110:50'

SELECT 
CAST(
    CAST(LEFT(@s1,CHARINDEX(':',@s1)-1) AS INT) + 
    CAST(LEFT(@s2,CHARINDEX(':',@s2)-1) AS INT) + 
    (CAST(RIGHT(@s1,LEN(@s1)-CHARINDEX(':',@s1)) AS INT) + CAST(RIGHT(@s2,LEN(@s2)-CHARINDEX(':',@s2)) AS INT))/60  
    as nvarchar) 
+':'+ 
CAST(
    (CAST(RIGHT(@s1,LEN(@s1)-CHARINDEX(':',@s1)) AS INT) + 
    CAST(RIGHT(@s2,LEN(@s2)-CHARINDEX(':',@s2)) AS INT))
    %60 
    AS nvarchar)

Answer 3

只是另一种选择

Declare @YourTable table (column1 varchar(25),column2 varchar(25))
Insert Into @YourTable values
('149:10','110:20')

Select A.*
      ,TotalTime = Format(B.Sec/3600    ,'0' )  
                  +Format(B.Sec%3600/60,':00')  
 From  @YourTable A
 Cross Apply (values (
                      (3600*parsename(replace(column1,':','.'),2)+60*parsename(replace(column1,':','.'),1))
                     +(3600*parsename(replace(column2,':','.'),2)+60*parsename(replace(column2,':','.'),1))
                     )
             ) B (sec)

<强>返回

column1 column2 TotalTime
149:10  110:20  259:30

添加两个时间（HH：MM）列
