开发日志：按照每月每天，每年每月，每月每周汇总数据

按每月每日

public DataSet MonthDayList(DateTime dt)
{
StringBuilder strSql = new StringBuilder();
strSql.Append("Select DateNum,PlanID,Sum(DayClick) As SumCount,DateUpdated ");
strSql.Append("From vA4_SumDayCount ");
strSql.Append("Where DateDiff(Month,DateUpdated,@dt) = 0 ");
strSql.Append("And PlanID = @PlanID Group By DateNum,PlanID,DateUpdated ");
strSql.Append("Order By DateNum DESC");
SqlParameter[] p = {
SqlHelper.MakeInParam("@dt", SqlDbType.DateTime, 8, dt),
SqlHelper.MakeInParam("@PlanID", SqlDbType.Int, 4, _ID)
};
return SqlHelper.ExecuteDataset(clsConfig.conn, CommandType.Text, strSql.ToString(), p);
}

按每月每周

public DataSet MonthWeekList(DateTime dt)
{
StringBuilder strSql = new StringBuilder();
strSql.Append("Select CAST(DATEPART(wk, DateUpdated) AS VARCHAR) AS DateWeek,Sum(DayClick) AS SumCount ");
strSql.Append("From vA4_SumdayCount Where PlanID = @PlanID And DateDiff(Year,DateUpdated,@dt) = 0");
strSql.Append("Group By CAST(DATEPART(wk, DateUpdated) AS VARCHAR) Order By DateWeek DESC");
SqlParameter[] p = {
SqlHelper.MakeInParam("@PlanID", SqlDbType.Int, 4, _ID),
SqlHelper.MakeInParam("@dt", SqlDbType.DateTime, 8, dt)
};
return SqlHelper.ExecuteDataset(clsConfig.conn, CommandType.Text, strSql.ToString(), p);
}

按每年每月

public DataSet YearMonthList(DateTime dt)
{
StringBuilder strSql = new StringBuilder();
strSql.Append("Select SUBSTRING(CAST(DateNum AS VARCHAR), 1, 6) AS DateMonth,Sum(DayClick) AS SumCount ");
strSql.Append("From vA4_SumdayCount Where PlanID = @PlanID And DateDiff(Year,DateUpdated,@dt) = 0 ");
strSql.Append("Group by SUBSTRING(CAST(DateNum AS VARCHAR), 1, 6) ");
strSql.Append("Order By DateMonth DESC");
SqlParameter[] p = {
SqlHelper.MakeInParam("@PlanID", SqlDbType.Int, 4, _ID),
SqlHelper.MakeInParam("@dt", SqlDbType.DateTime, 8, dt)
};
return SqlHelper.ExecuteDataset(clsConfig.conn, CommandType.Text, strSql.ToString(), p);
}
