1. sql语句中得到JAVA长整型的当前时间
declare @aIn_date bigint
set @aIn_date=DATEDIFF ( second , '1970-01-01 08:00:00.000' , getdate() ) -- 秒数
set @aIn_date = @aIn_date*1000 + datepart(ms,getdate()) -- 毫秒数
2. 以datetime类型方式,显示表中bigint型的时间
select DATEADD(HOUR, DATEDIFF(HOUR,'19000101 00:00', '19700101 08:00'), CAST(create_date / (1000.0*3600*24.0) AS DATETIME)) from t_test
说明, create_date是个bigint类型的字段
写个自定义函数来显示更方便:
-- =============================================
-- Author: Michael.Du
-- Create date: 2010-06-23
-- Description: 将bigint日期转为datetime型,方便查看 (本函数目前只是用于调试查看,没有参与实际生产)
-- 调用示例:
-- select dbo.toDateTime(create_date) from XXXX
-- =============================================
ALTER FUNCTION [dbo].[toDateTime](
@bigint_date bigint
)
RETURNS datetime
AS
BEGIN
declare @aa datetime
select @aa = DATEADD(HOUR, DATEDIFF(HOUR,'19000101 00:00', '19700101 08:00'), CAST(@bigint_date / (1000.0*3600*24.0) AS DATETIME))
RETURN @aa
END
