sqlserver存储时间

‘壹’ sql server 日期时间 存储时怎么能不让它显示毫秒，后面那3个000

存储格式更改下即可。如下:

DateTime.Now.ToString("yyyy-MM-dd HH:mm:ss")。

小贴士:

此处是一个如何使用不同的DATETIME2精度值来显示不同的时间格式的示例：

PRINT @T1;
PRINT @T2; DECLARE @T0 time(0) = '16:59:11.1234567';DECLARE @T1 time(1) = '16:59:11.1234567';DECLARE @T2 time(2) = '16:59:11.1234567';DECLARE @T3 time(3) = '16:59:11.1234567';DECLARE @T4 time(4) = '16:59:11.1234567';DECLARE @T5 time(5) = '16:59:11.1234567';DECLARE @T6 time(6) = '16:59:11.1234567';DECLARE @T7 time(7) = '16:59:11.1234567';PRINT @T0;
PRINT @T3;
PRINT @T4;
PRINT @T5;
PRINT @T6;
PRINT @T7;

当运行上述代码时将会得到如下结果：

16:59:11
16:59:11.1
16:59:11.12
16:59:11.123
16:59:11.1235
16:59:11.12346
16:59:11.123457
16:59:11.1234567

‘贰’ sqlserver 包含一个时间区间的存储过程如何写

create PROCEDURE ps_test
declare @id varchar(50)
as
begin
declare @from_date datetime
declare @to_date datetime
create table #tt_table (id,output_date)
select @from_date = 开始时间, @to_date = 结束时间
from A
where id = @id
while(@from_date <= @to_date)
begin
insert into #tt_table(id,output_date)
values( @id,@from_date)

DATEADD(day,1,@from_date)
end
select id, output_date
from #tt_table
end
go
