Question

我有一个VS2010 .Net 4.0 Web服务，它应该返回一个DataTable记录。它似乎一直很好，直到今天。如果我通过SQL Server Management Studio将5个参数（3个int和2个日期时间）传递给它，我会得到所有的行。但是，当我通过服务运行并检查ds.Fill（MyTable）行上的变量时，某些行不显示。

我刚注意到的奇怪之处，当我使用TagNumber 1-270搜索项目时，我得到了SSMS和.Fill中的所有行。每当我尝试返回TagNumbers在271和300之间的项目时，所有这些行都显示在SSMS中，但它们都没有返回到.Fill中。我检查过的所有东西都超过了300个，并且都符合预期。

这是我存储的程序。我不能说特别的。

ALTER PROCEDURE [dbo].[FetchLicenseReceiptData] (
    @ForYear INT,
    @StartNumber INT,
    @EndNumber INT,
    @StartDate DATETIME,
    @EndDate DATETIME

BEGIN

    LEFT OUTER JOIN data.Dog          AS   d ON l.DogID = d.ID
    LEFT OUTER JOIN data.Owner        AS   o ON d.OwnerID = o.ID

        FROM
                            data.OwnerPhone  AS  op
            LEFT OUTER JOIN data.Phone       AS   p ON op.PhoneID = p.ID
            LEFT OUTER JOIN lookup.PhoneType AS lpt ON p.PhoneTypeID = lpt.ID
        WHERE
            p.IsPrimary = 1
    ) AS jpi ON o.ID = jpi.OwnerID
    LEFT OUTER JOIN (
        SELECT
            e.Address AS EmailAddress,
            let.Name AS EmailType,
            oe.OwnerID AS OwnerID
        FROM
                            data.OwnerEmail  AS  oe
            LEFT OUTER JOIN data.Email       AS   e ON oe.EmailID = e.ID
            LEFT OUTER JOIN lookup.EmailType AS let ON e.EmailTypeID = let.ID
        WHERE
            e.IsPrimary = 1
    ) AS jei ON o.ID = jei.OwnerID
WHERE
        l.ForYear = @ForYear
    AND l.TagNumber >= @StartNumber
    AND l.TagNumber <= @EndNumber
    AND l.Issued >= @StartDate
    AND l.Issued <= @EndDate
ORDER BY
    l.TagNumber

END

这里结束的是我调用SP调用的方法：

    public DataTable FetchLicenseReceiptData(int ForYear, int StartNumber, int EndNumber, DateTime StartDate, DateTime EndDate) {
        DataTable Result = new DataTable();

        try {
            using (SqlConnection con = new SqlConnection(ConfigurationManager.ConnectionStrings["DogLicensingContext"].ConnectionString)) {
                SqlCommand cmd = new SqlCommand("FetchLicenseReceiptData", con);
                cmd.CommandType = CommandType.StoredProcedure;
                cmd.Parameters.Add(new SqlParameter("@ForYear", ForYear));
                cmd.Parameters.Add(new SqlParameter("@StartNumber", StartNumber));
                cmd.Parameters.Add(new SqlParameter("@EndNumber", EndNumber));
                cmd.Parameters.Add(new SqlParameter("@StartDate", StartDate));
                cmd.Parameters.Add(new SqlParameter("@EndDate", EndDate));

                con.Open();

                SqlDataAdapter ds = new SqlDataAdapter(cmd);
                ds.Fill(Result);
                Result.TableName = "LicenseReceiptDataAutoPrint";
            } // using the connection
        } catch (Exception e) {

        } // try-catch

        return Result;
    } // FetchLicenseReceiptData - Method

所以在我运行以下内容的SSMS中：

FetchLicenseReceiptData 2013,270,271，'2012-01-01'，'2012-12-31'

我得到2条记录。当通过.Fill运行我只得到一个（270）

当我在SSMS中运行以下内容时：

FetchLicenseReceiptData 2013,271,300，'2012-01-01'，'2012-12-31'

我得到了所有30行。但是通过.Fill它没有返回。

最后，如果我运行以下内容：

FetchLicenseReceiptData 2013,301,310，'2012-01-01'，'2012-12-31'

我在SSMS和.Fill都获得全部10分。

作为返回数据的示例，这里是SSMS中返回的270和271数据。我用波形符（〜）字符

替换了标签

这个很奇怪。希望你们中的一个大师可以帮助我。

解：感谢@EJBrennan提供的SQL Profiler建议。我之前从未使用它，但它指出了我正确的方向。这是实际上被发送到SQL：

exec FetchLicenseReceiptData @ ForYear = 2013，@ StartNumber = 270，@ EndNumber = 271，@ StartDate ='2012-01-01 00:00:00'，@ EndDate ='2012-12-13 00:00:00 “

当我运行它时，它给了我一行而不是2.基本上，当时00:00:00的值是相同的除外。我最后将以下内容添加到我的存储过程的顶部以强迫事情正确：

SET @StartDate = DATEADD(DAY, DATEDIFF(DAY, 0, @StartDate), 0) -- Beginning of given Date
SET @EndDate   = DATEADD(DAY, DATEDIFF(DAY, 0, @EndDate),   1) -- End of given Date

这会传递任何传入的@StartDate并强制它到当天的0：0：0。然后它将@EndDate设置为NEXT日，并将时间设置为0：0：0。

同样在WHERE子句中SP的底部，我将＆lt; = @EndDate更改为＆lt; EndDate从现在开始，@ EndDate是在日期过后的一天。

再次感谢@EJBrennan

存储过程获取正确的行但SqlDataAdapter不会填充相同的行数
