怎么插入datetime 一条数据 sqlserver

可以使用 CONVERT 函数，将 字符串类型的数据，转换为 datetime 类型。
CONVERT(DATETIME, ’2012-01-02 09:06:18’, 120)
其中那个 120 的参数， 取决于你前面的字符串信息是什么格式的。
执行下面的语句， 就可以一一对应得上。
SELECT 0 AS ID , Convert(VARCHAR(30), GETDATE(), 0 ) AS result UNION ALL
SELECT 100 AS ID , Convert(VARCHAR(30), GETDATE(), 100) AS result UNION ALL
SELECT 1 AS ID , Convert(VARCHAR(30), GETDATE(), 1 ) AS result UNION ALL
SELECT 101 AS ID , Convert(VARCHAR(30), GETDATE(), 101) AS result UNION ALL
SELECT 2 AS ID , Convert(VARCHAR(30), GETDATE(), 2 ) AS result UNION ALL
SELECT 102 AS ID , Convert(VARCHAR(30), GETDATE(), 102) AS result UNION ALL
SELECT 2 AS ID , Convert(VARCHAR(30), GETDATE(), 2 ) AS result UNION ALL
SELECT 102 AS ID , Convert(VARCHAR(30), GETDATE(), 102) AS result UNION ALL
SELECT 3 AS ID , Convert(VARCHAR(30), GETDATE(), 3 ) AS result UNION ALL
SELECT 103 AS ID , Convert(VARCHAR(30), GETDATE(), 103) AS result UNION ALL
SELECT 4 AS ID , Convert(VARCHAR(30), GETDATE(), 4 ) AS result UNION ALL
SELECT 104 AS ID , Convert(VARCHAR(30), GETDATE(), 104) AS result UNION ALL
SELECT 5 AS ID , Convert(VARCHAR(30), GETDATE(), 5 ) AS result UNION ALL
SELECT 105 AS ID , Convert(VARCHAR(30), GETDATE(), 105) AS result UNION ALL
SELECT 6 AS ID , Convert(VARCHAR(30), GETDATE(), 6 ) AS result UNION ALL
SELECT 106 AS ID , Convert(VARCHAR(30), GETDATE(), 106) AS result UNION ALL
SELECT 7 AS ID , Convert(VARCHAR(30), GETDATE(), 7 ) AS result UNION ALL
SELECT 107 AS ID , Convert(VARCHAR(30), GETDATE(), 107) AS result UNION ALL
SELECT 8 AS ID , Convert(VARCHAR(30), GETDATE(), 8 ) AS result UNION ALL
SELECT 108 AS ID , Convert(VARCHAR(30), GETDATE(), 108) AS result UNION ALL
SELECT 9 AS ID , Convert(VARCHAR(30), GETDATE(), 9 ) AS result UNION ALL
SELECT 109 AS ID , Convert(VARCHAR(30), GETDATE(), 109) AS result UNION ALL
SELECT 10 AS ID , Convert(VARCHAR(30), GETDATE(), 10 ) AS result UNION ALL
SELECT 110 AS ID , Convert(VARCHAR(30), GETDATE(), 110) AS result UNION ALL
SELECT 11 AS ID , Convert(VARCHAR(30), GETDATE(), 11 ) AS result UNION ALL
SELECT 111 AS ID , Convert(VARCHAR(30), GETDATE(), 111) AS result UNION ALL
SELECT 12 AS ID , Convert(VARCHAR(30), GETDATE(), 12 ) AS result UNION ALL
SELECT 112 AS ID , Convert(VARCHAR(30), GETDATE(), 112) AS result UNION ALL
SELECT 13 AS ID , Convert(VARCHAR(30), GETDATE(), 13 ) AS result UNION ALL
SELECT 113 AS ID , Convert(VARCHAR(30), GETDATE(), 113) AS result UNION ALL
SELECT 14 AS ID , Convert(VARCHAR(30), GETDATE(), 14 ) AS result UNION ALL
SELECT 114 AS ID , Convert(VARCHAR(30), GETDATE(), 114) AS result UNION ALL
SELECT 20 AS ID , Convert(VARCHAR(30), GETDATE(), 20 ) AS result UNION ALL
SELECT 120 AS ID , Convert(VARCHAR(30), GETDATE(), 120) AS result UNION ALL
SELECT 21 AS ID , Convert(VARCHAR(30), GETDATE(), 21 ) AS result UNION ALL
SELECT 121 AS ID , Convert(VARCHAR(30), GETDATE(), 121) AS result

Python123上面有关datetime库函数的使用的一道程序题求助

按照题目要求编写的Python程序如下

from datetime import datetime

day=input()

day1=list(map(int,day.split(’,’)))

x=datetime(day1,day1,day1,day1,day1)

week=x.weekday()

print(“这一天是星期{}。“.format(week+1))

timestamp=datetime.timestamp(x)

utc=datetime.utcfromtimestamp(timestamp)

print(“这一天的UTC时间是{}。“.format(utc.isoformat()))

print(x.strftime(’这一天是%b月--%d日--%Y年，%I点%M分%p。’))

C#DateTime的用法

1、输出当前时间

DateTime now = DateTime.Now;

Console.WriteLine(now);

2、输出年月日 - 时分秒(为0)

DateTime now = DateTime.Now;

Console.WriteLine(now.Date.ToString());

3、输出年月日 - 时分格式时间

DateTime now = DateTime.Now;

Console.WriteLine(now.ToString(“yyyy-MM-dd hh:mm“));

4、输出年月日格式的时间

DateTime now = DateTime.Now;

Console.WriteLine(now.ToString(“yyyy-MM-dd“));

5、输出时分秒格式的时间

DateTime now = DateTime.Now;

Console.WriteLine(now.ToString(“HH:mm:ss“));

6、输出当前时间增加一天

DateTime afterNow = now.AddDays(1);

Console.WriteLine(afterNow);

7、输出当前时间减去一天

DateTime beforeNow = now.AddDays(-1);

Console.WriteLine(beforeNow);

Delphi 怎么使用时间函数

date 函数 返回当前的日期
datetimetofiledate 函数 将delphi的日期格式转换为dos的日期格式
datetimetostr 函数 将日期时间格式转换为字符串
datetimetostring 函数 将日期时间格式转换为字符串
datetostr 函数 将日期格式转换为字符串
dayofweek 函数 返回星期的数值
dec 函数 递减变量值
decodedate 函数 将日期格式分解为年月日
decodetime 函数 将时间格式分解为时、分、秒、毫秒

datetime 格式的时间如何截取年月

这个需要用convert转换一下啦

SELECT SUM(BO_UDDataPickUpReport_STSFCMain.fInQuantity) 
FROM BO_UDDataPickUpReport_STSFCMain 
GROUP BY BO_UDDataPickUpReport_STSFCMain.cInvCode,
CONVERT(VARCHAR(6),BO_UDDataPickUpReport_STSFCMain.dDate,112)

其实你可以这样看看结果就知道了

SELECT CONVERT(VARCHAR(6),GETDATE(),112)

VARCHAR(6)这个地方限制长度就是取前六位了
