c# - 我没有得到所有数据

问题描述

我正在尝试使用这样的存储过程从我的数据库中获取一些数据

[getAllRecordsForSalaryCalculation]
    @year NCHAR(10),
    @Bruger NCHAR(20)
AS
BEGIN
    IF (@year = 2018)
    BEGIN
        SELECT SUM(Overtid1) AS overtid1Before 
        FROM timer 
        WHERE DateForQuery >= CONVERT(DATETIME, '2018-12-01') 
          AND DateForQuery <= CONVERT(DATETIME, '2019-04-30') 
          AND Bruger LIKE '%@Bruger%'

        SELECT SUM(Overtid1) AS overtid1after 
        FROM timer 
        WHERE DateForQuery >= CONVERT(DATETIME, '2019-05-01') 
          AND DateForQuery <= CONVERT(DATETIME, '2019-11-30') 
          AND Bruger LIKE '%@Bruger%'

        SELECT SUM(Overtid2) AS overtid2Before 
        FROM timer 
        WHERE DateForQuery >= CONVERT(DATETIME, '2018-12-01') 
          AND DateForQuery <= CONVERT(DATETIME, '2019-04-30') 
          AND Bruger LIKE '%@Bruger%'

        SELECT SUM(Overtid2) AS overtid2after 
        FROM timer 
        WHERE DateForQuery >= CONVERT(DATETIME, '2019-05-01') 
          AND DateForQuery <= CONVERT(DATETIME, '2019-11-30') 
          AND Bruger LIKE '%@Bruger%'

        SELECT SUM(Vagt) AS vagtBefore 
        FROM timer 
        WHERE DateForQuery >= CONVERT(DATETIME, '2018-12-01') 
          AND DateForQuery <= CONVERT(DATETIME, '2019-04-30') 
          AND Bruger LIKE '%@Bruger%'

        SELECT SUM(Vagt) AS vagtafter 
        FROM timer 
        WHERE DateForQuery >= CONVERT(DATETIME, '2019-05-01') 
          AND DateForQuery <= CONVERT(DATETIME, '2019-11-30') 
          AND Bruger LIKE '%@Bruger%'
    END
END

我的代码看起来像这样

con.Open();

SqlDataAdapter da = new SqlDataAdapter("getAllRecordsForSalaryCalculation", con);
da.SelectCommand.CommandType = CommandType.StoredProcedure;

da.SelectCommand.Parameters.AddWithValue("@year", year);
da.SelectCommand.Parameters.AddWithValue("@Bruger", bruger);

da.Fill(ds);
con.Close();

但我只得到第一个选择并且它是空的。那里有数据，当我将它作为查询运行时它可以工作。我不确定我在哪里做错了。有人可以帮忙吗？

解决方案

我对程序的建议：

CREATE PROC [getAllRecordsForSalaryCalculation] (@year INT, @Bruger NVARCHAR(20)) AS
BEGIN
    SET DATEFORMAT YMD
    IF (@year = 2018)
    BEGIN
        WITH tm AS (
            SELECT Overtid1 AS Ov1, Overtid2 AS Ov2, Vagt AS Vag, DateForQuery AS Dt
            FROM timer
            WHERE Bruger LIKE '%' + @Bruger + '%'
                AND DateForQuery BETWEEN '2018-12-01' AND '2019-11-30'
        )
        SELECT
             overtid1Before =(SELECT SUM(Ov1) FROM tm WHERE Dt BETWEEN '2018-12-01' AND '2019-04-30')
            ,overtid1After  =(SELECT SUM(Ov1) FROM tm WHERE Dt BETWEEN '2019-05-01' AND '2019-11-30')
            ,overtid2Before =(SELECT SUM(Ov2) FROM tm WHERE Dt BETWEEN '2018-12-01' AND '2019-04-30')
            ,overtid2After  =(SELECT SUM(Ov2) FROM tm WHERE Dt BETWEEN '2019-05-01' AND '2019-11-30')
            ,vagtBefore     =(SELECT SUM(Vag) FROM tm WHERE Dt BETWEEN '2018-12-01' AND '2019-04-30')
            ,vagtAfter      =(SELECT SUM(Vag) FROM tm WHERE Dt BETWEEN '2019-05-01' AND '2019-11-30')
    END
END
