主题：二表间光标对应？

什么表都好，数据已经加载进来了，就要用##。

如果你不确定，就两个都试一下吧

Dim cmd As new SQLCommand
'如果是外部数据源,就加上外部数据源的名字
cmd.CommandText = "select * from {报销名单}"
Dim dt1 As DataTable = cmd.ExecuteReader
cmd.CommandText = "select * from {基本资料}"
Dim dt2 As DataTable = cmd.ExecuteReader

For Each dr As DataRow In DataTables("病案首页").DataRows
    Dim fdr1 As DataRow = dt1.Find("身份证号 = '" & dr("身份证号") & "' and 入院时间 = #" & dr("入院时间") & "# and 入院时间 Is not null")
    Dim fdr2 = dt2.Find("身份证号 = '" & dr("身份证号") & "'")
    If fdr1 IsNot Nothing Then
        dr("姓名") = fdr1("姓名")
    End If
    If fdr2 IsNot Nothing Then
        dr("性别") = fdr2("性别")
    End If
Next

”病案首页“是从“报销名单”，“基本资料"二个表资料加载而来，这里少了个”增加行“的代码，我希望是依据“报销名单”增加行，请帮改下，多谢了

For Each dr As DataRow In dt1.DataRows
    If DataTables("病案首页").Find("身份证号 = '" & dr("身份证号") & "' and 入院时间 = #") Is Nothing Then
        Dim ndr As DataRow = DataTables("病案首页").AddNew
        ndr("身份证号") = dr("身份证号")
        ndr("入院时间") = dr("入院时间")
