Dim dt As DataTable
Dim b As New SQLGroupTableBuilder("统计表3","资产总表")
b.C
b.Groups.AddDef("采购信息_购买时间",DateGroupEnum.Year,"年")
b.Groups.AddDef("采购信息_购买时间",DateGroupEnum.Quarter ,"季度")
b.Groups.AddDef("地点") 
b.Groups.AddDef("部门") 
b.Groups.AddDef("资产类型") 
b.Totals.AddDef("_Identify",AggregateEnum.Count,"设备数") 
dt = b.Build(False) \'参数设置为False,生成一个临时表,不在主界面显示
\'然后根据统计表生成目录树
Dim trv As WinForm.TreeView = e.Form.Controls("TreeView1")
trv.BuildTree(dt, "资产类型|地点|部门")
trv.StopRedraw

For Each nd As WinForm.TreeNode In trv.AllNodes
    Dim Year As Integer = nd.DataRow("年")
    Dim Quarter As Integer = nd.DataRow("季度")
    Dim Count  As String = nd.DataRow("设备数")
   Dim place As String = nd.DataRow("地点")
       Dim part As String = nd.DataRow("部门")
Dim lx As String = nd.DataRow("资产类型")
\'msgbox(nd.text)

    Select Case nd.Level
        Case 0
            nd.Text = nd.text & "(" & dt.Compute("Sum(设备数)","资产类型 = " & lx) & "台)"
     
    End Select
Next
trv.Nodes.Insert("加载所有行","加载所有行(" & dt.Compute("Sum(设备数)") & "台)",0)
trv.ResumeRedraw

黄色部分的代码好像有问题。提示找不到 某某列

改成

 

nd.Text = nd.text & "(" & dt.Compute("Sum(设备数)","资产类型 = \'" & lx & "\'") & "台)"
