苏州老街 发表于：2025/1/20 18:01:00老师好，我想在下面代码中再增加两个计算条件。标出的是新增条件。
Select Case e.DataCol.Name
Case "客户id","商品名称","摘要","付款金额"
Dim drs As List(of DataRow)
Dim Filter As String
Filter = "[_Identify] >= " & e.DataRow("_Identify") & " And [客户id] = '" & e.DataRow("客户id") & "'"
drs = e.DataTable.Select(Filter)

苏州老街 发表于：2025/1/21 16:18:00老师，“摘要”列里有两个字段一个是“押金”另一个是“退还押金”还有两列是“付款金额”，“累计付款”。我想如果是押金就累加付款金额列的数据如果是退还押金就减去付款金额列中的数据。

我想不增加列的前提下根据前面两列的条件”客户，客户ID”来计算押金和押金退还。

苏州老街 发表于：2025/1/21 20:16:00老师，我前面要加两个条件即谁给的押金，退给谁的。搞不明白。
客户，客户ID
