怎么插入datetime 一条数据 sqlserver

Answer 1

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

120???

追答

120 的意思就是，你的字符串的格式，必须是 '2012-01-02 09:06:18' 这个样子的。
也就是 年年年年-月月-日日 时时:分分:秒秒 这样的格式。

你要是
SELECT CONVERT(DATETIME, '01/02/12', 120)
那么结果就是
-----------------------
消息 241，级别 16，状态 1，第 1 行
从字符串向 datetime 转换时失败。

但是你指定了正确的参数
SELECT CONVERT(DATETIME, '01/02/12', 1)
-----------------------
2012-01-02 00:00:00.000
(1 行受影响)

是用java编程吗？是想sqlserver中加一条含有时间类型的数据吗？首先得到当前系统时间，转换成你所有的格式，再转换成java.sql.Date 就可以啦
