Question

我有一个动态创建的GridView，我使用sql代码WITH ROLLUP来显示列的总数。但是可以在空白单元格中显示单词总数吗？

GridView的：

<asp:GridView runat="server" 
                                id="gvResults" 
                                CssClass="tblResults" 
                                onrowcreated= "gvResults_RowCreated"
                                AllowSorting="true" 
                                OnSortCommand="gvResults_Sort" 
                                DataKeyField="ID" 
                                AutoGenerateColumns="true"
                                Visible =" true">
                            <HeaderStyle CssClass="tblResultsHeader" />
                            <AlternatingRowStyle BackColor="#EEEEEE" />

                        </asp:GridView>

显示GridView的SQL代码：

select

    c.Name,
    COUNT(distinct jn.ID) as Jobs,
    sum(case when (select count(jbs.status) from jobstat jbs where jbs.jobid=jn.id and jbs.Status=''DEL'')>0 then 1 else 0 end) as EPOD,
     sum(case when (select count(jbs.status) from jobstat jbs where jbs.jobid=jn.id and jbs.Status=''POD'')>0 then 1 else 0 end) as POD,
    SUM((select COUNT(ID) from job_debriefs WHERE JobID = jn.ID)) as Debriefs,
    FROM customer c
    LEFT JOIN job_new jn ON jn.JobOwnerID = c.ID
    LEFT JOIN manifestdetails md ON md.JobID = jn.ID and md.ColDelReturn = ''C''
    LEFT JOIN manifest man ON md.ManifestID = man.ID
    WHERE jn.IsActive = 1 AND c.Company_ID = 12
    GROUP BY c.Name WITH ROLLUP

Answer 1

您可以使用GROUPING SQL函数来确定c.Name是否卷起特定行：

select
ifnull(c.Name,'TOTAL') as Name,
COUNT(distinct jn.ID) as Jobs,
sum(case when (select count(jbs.status) from jobstat jbs where jbs.jobid=jn.id and jbs.Status=''DEL'')>0 then 1 else 0 end) as EPOD,
 sum(case when (select count(jbs.status) from jobstat jbs where jbs.jobid=jn.id and jbs.Status=''POD'')>0 then 1 else 0 end) as POD,
SUM((select COUNT(ID) from job_debriefs WHERE JobID = jn.ID)) as Debriefs,
FROM customer c
LEFT JOIN job_new jn ON jn.JobOwnerID = c.ID
LEFT JOIN manifestdetails md ON md.JobID = jn.ID and md.ColDelReturn = ''C''
LEFT JOIN manifest man ON md.ManifestID = man.ID
WHERE jn.IsActive = 1 AND c.Company_ID = 12
GROUP BY c.Name WITH ROLLUP

但是，请注意，如果原始c.Name列中允许NULL值，则此值也将转换为单词“TOTAL”。据我所知，在MySQL中没有解决方法（当然除了消除NULL值）。

您可以参考to this link。它可能对你有所帮助。

protected void GridView1_RowDataBound(object sender, GridViewRowEventArgs e)
{
  if (e.Row.RowType == DataControlRowType.DataRow)
  {
    Label Salary = (Label)e.Row.FindControl("lblSalary");        
    m = m + int.Parse(Salary.Text);
    //Table tb = new Table();
  }

  if (e.Row.RowType == DataControlRowType.Footer)
  {
    Label lblTotalPrice = (Label)e.Row.FindControl("Salary");
    lblTotalPrice.Text = m.ToString();
  }
}

将单词TOTAL添加到Gridview的最后一行
