各位老师好，遇到一个基础的问题研究半天没弄会，请教下老师。。

此主题相关图片如下：界面.jpg

想实现，通过目录树选择的条件来做子查询

Dim trv As WinForm.TreeView = e.Sender
Dim flt As String
For Each nd As WinForm.TreeNode In e.node.Nodes \'清除子节点选中状态
    nd.Checked = False
Next
If e.node.ParentNode IsNot Nothing Then \'去掉父节点选中状态
    e.node.ParentNode.Checked = False
End If
For Each nd As WinForm.TreeNode In trv.AllNodes
      If nd.Checked Then
        If flt > "" Then
            flt = flt & " Or "  \'注意用or而不是And
        End If
        If nd.Level = 0 Then \'注意下面的条件都要用括号括起来
            flt = flt & "( 方案名称 = \'" & nd.Text & "\')"
        Else
            flt = flt & "( 方案名称 = \'" & nd.ParentNode.Text & "\' And 鱼群名称 = \'" & nd.Text & "\')"
        End If
    End If   
Next

\'DataTables("汇总分析_VIP回访记录").loadFilter = flt
\'DataTables("汇总分析_VIP回访记录").load

Dim sql As String
sql = "Select 消费日期 As 日期, 归属门店, SUM(实销金额) As VIP销售额, COUNT(DISTINCT VIP卡号) As VIP销售笔数 FROM {VIP消费信息} where VIP电话 in  (select VIP电话 from VIP回访记录 where 方案名称 =  )  GROUP BY  消费日期, 归属门店 "
Tables("汇总分析_到店人数统计").Fill( sql,"VIP数据",True)

谢谢Bin老师。

Dim sql As String
sql = "Select 消费日期 As 日期, 归属门店, SUM(实销金额) As VIP销售额, COUNT(DISTINCT VIP卡号) As VIP销售笔数 FROM {VIP消费信息} where VIP电话 in  (select VIP电话 from VIP回访记录 where 方案名称 =  ) 【这里想要实现的是查询记录的条件是flt，但是子查询只能是具体的字段条件，而不能像loadfilter = flt 这样写。】GROUP BY  消费日期, 归属门店 "
Tables("汇总分析_到店人数统计").Fill( sql,"VIP数据",True)

Dim trv As WinForm.TreeView = e.Sender
Dim flt As String
Dim filter As String = "1=2"
For Each nd As WinForm.TreeNode In e.node.Nodes \'清除子节点选中状态
    nd.Checked = False
Next
If e.node.ParentNode IsNot Nothing Then \'去掉父节点选中状态
    e.node.ParentNode.Checked = False
End If
For Each nd As WinForm.TreeNode In trv.AllNodes
      If nd.Checked Then
        If flt > "" Then
            flt = flt & " Or "  \'注意用or而不是And
        End If
        If nd.Level = 0 Then \'注意下面的条件都要用括号括起来
            flt = flt & "( 方案名称 = \'" & nd.Text & "\')"
    filter &= " or 方案名称 = \'" & nd.Text & "\'"
        Else
            flt = flt & "( 方案名称 = \'" & nd.ParentNode.Text & "\' And 鱼群名称 = \'" & nd.Text & "\')"
    filter &= " or 方案名称 = \'" & nd.ParentNode.Text & "\'"
        End If
    End If   
Next

\'DataTables("汇总分析_VIP回访记录").loadFilter = flt
\'DataTables("汇总分析_VIP回访记录").load

4楼是复杂的，这个是简单的

Dim trv As WinForm.TreeView = e.Sender
Dim flt As String = "1=2"
For Each nd As WinForm.TreeNode In e.node.Nodes \'清除子节点选中状态
    nd.Checked = False
Next
If e.node.ParentNode IsNot Nothing Then \'去掉父节点选中状态
    e.node.ParentNode.Checked = False
End If
For Each nd As WinForm.TreeNode In trv.AllNodes
      If nd.Checked Then
        If nd.Level = 0 Then \'注意下面的条件都要用括号括起来
            flt = flt & " or ( 方案名称 = \'" & nd.Text & "\')"
        Else
            flt = flt & " or ( 方案名称 = \'" & nd.ParentNode.Text & "\' And 鱼群名称 = \'" & nd.Text & "\')"
        End If
    End If   
Next

\'DataTables("汇总分析_VIP回访记录").loadFilter = flt
\'DataTables("汇总分析_VIP回访记录").load

Dim sql As String
sql = "Select 消费日期 As 日期, 归属门店, SUM(实销金额) As VIP销售额, COUNT(DISTINCT VIP卡号) As VIP销售笔数 FROM {VIP消费信息} where VIP电话 in  (select VIP电话 from VIP回访记录 where " & flt & " )  GROUP BY  消费日期, 归属门店 "
Tables("汇总分析_到店人数统计").Fill( sql,"VIP数据",True)

对，哎，居然可以这样子，我怎么没想到呢！

谢谢甜老师！！
