我想發送逗號分隔的日期字符串到我的存儲過程,在IN子句中使用。 但是,我收到錯誤「從字符串轉換日期和/或時間時轉換失敗。」存儲過程,傳遞日期列表,逗號分隔。轉換錯誤
我正試圖使用這些日期來查找匹配的價格。 C#:
StringBuilder LastDaysOfEveryMonth = new StringBuilder();
DataAccess da = new DataAccess();
SqlCommand cm = new SqlCommand();
cm.CommandType = CommandType.StoredProcedure;
var pList = new SqlParameter("@DateList", DbType.String);
pList.Value = LastDaysOfEveryMonth.ToString();
cm.Parameters.Add(pList);
...
cm.CommandText = "spCalculateRollingAverage";
DataSet ds = da.ExecuteDataSet(ref cm);
調試時它,所傳遞的字符串的值是:
'2013-07-31','2013-08-30','2013-09-30','2013-10-31','2013-11-29','2013-12-31',
'2014-01-31','2014-02-28','2014-03-31','2014-04-03',
與的DbType字符串和SQLDbType NVARCHAR。
任何意見將不勝感激! SQL:
CREATE PROCEDURE [dbo].[spCalculateRollingAverage]
@StartDate DateTime,
@EndDate DateTime,
@Commodity nvarchar(10),
@PeakType nvarchar (10),
@BaseID int,
@NumberOfMonths int,
@DateList nvarchar(MAX)
AS
BEGIN
select TermDescription,ContractDate,Price,SortOrder into #tbtp from BaseTermPrice
inner hash join Term
on
Term.TermID = BaseTermPrice.TermID
where
BaseID = @BaseID and ((@PeakType IS NULL and PeakType is null) or
(@PeakType IS NOT NULL and [email protected]))
and ((@DateList IS NULL and ContractDate between @StartDate and @EndDate)
or (@StartDate IS NULL and ContractDate in (@DateList)))
order by
ContractDate,SortOrder
