我有一个向数据库添加行的方法(sql server 2005)。它有问题,因为当我有一行UpdateDate 2000-12-31 23:59:59
时,它会插入2001-01-01 00:00:00.000
。可能吗?如果重要的话,环境文化是好的。这对我来说很神奇:/
private void AddInvestmentStatus(InvestmentData.StatusyInwestycjiRow investmentStatusesRow)
{
SqlCommand cmd = new SqlCommand("AddInvestmentStatus");
cmd.CommandType = CommandType.StoredProcedure;
SqlParameter param1 = new SqlParameter("@InvestmentId", SqlDbType.BigInt);
param1.Value = investmentStatusesRow.InvestmentId;
cmd.Parameters.Add(param1);
cmd.Parameters.AddWithValue("@enumInvestmentStatusID", investmentStatusesRow.EnumInvestmentStatusID);
cmd.Parameters.AddWithValue("@modifiedBy", "System");
cmd.Parameters.AddWithValue("@UpdateDate", investmentStatusesRow.UpdateDate);
cmd.Parameters.AddWithValue("@ModifiedOn", investmentStatusesRow.ModifiedOn);
cmd.Parameters.AddWithValue("@dataVersion", investmentStatusesRow.DataVersion);
cmd.Connection = new SqlConnection(MyProgram.Properties.Settings.Default.ConnectionString);
if (cmd.Connection.State != ConnectionState.Open)
cmd.Connection.Open();
try
{
cmd.ExecuteNonQuery();
}
catch (Exception e)
{
throw;
}
}
}
create PROCEDURE [dbo].[AddInvestmentStatus]
@inwestmentID bigint,
@enumInvestmentStatusId bigint,
@updateDate datetime,
@dataVersion int,
@modifiedBy nvarchar(50),
@modifiedOn datetime
AS
BEGIN

SET NOCOUNT ON;
DECLARE @investmentStatusesID bigint
INSERT INTO StatusyInwestycji(InwestycjaID)
VALUES (@inwestmentID)
SELECT @investmentStatusesID = SCOPE_IDENTITY();
INSERT INTO StatusyInwestycjiData(InvestmentStatusId, EnumStatusInwestycjiID,
UpdateDate, DataVersion, ModifiedBy, ModifiedOn)
VALUES (@investmentStatusesID, @enumInvestmentStatusId,
@updateDate, @dataVersion, @modifiedBy, @modifiedOn)
END

你确定你输入了23:59:59.000000或者你输入了23:59:59.9999999吗?
SQL DateTime数据类型的精度为3.33ms(它将舍入为0ms,3ms,7ms增量),这意味着您的23:59:59.9999将四舍五入到第二天的00:00:00.000000。
答案 1 :(得分:4)
我不知道你的情况是否会发生这种情况,但是一个已知的问题是,毫秒部分为.998或.999的日期时间值在插入数据库时会四舍五入到下一个整数秒,在最坏的情况下,可以将日期时间值包含在下一年。
答案 2 :(得分:3)
如果表有smalldatetime列,则可以,因为它具有1分钟的精度
见这里
select CONVERT(smalldatetime,'2000-12-31 23:59:59')
日期时间不会发生
select CONVERT(datetime,'2000-12-31 23:59:59')
发布表的DDL,确保还检查可能会转换为smalldatetime的触发器
