Question

我正在通过代码绑定gridview，我遇到的问题是显示的列之一是另一个表的外键，因此显示整数值。是否有可能显示该外键的文本值？

这就是我所做的：

     Dim cmd As New SqlCommand("SELECT ID, Customer, ContactPerson, Model, SerialNo, Status, Type, Value, InvoiceNo" &
                                  " FROM BackBillCustomer WHERE Status = 'Open'", cn)
        cn.Open()
            Dim rs As SqlDataReader = cmd.ExecuteReader()

            If rs.HasRows Then
                Dim adp As New SqlDataAdapter(cmd)
                Dim ds As New DataSet()
                rs.Close()
                adp.Fill(ds, "CustMeter")
                gvMeter.AllowPaging = True
                gvMeter.PageSize = (10)
                gvMeter.DataSource = ds
                gvMeter.DataBind()

                gvMeter.Attributes.Add("style", "word-break:keep-all;word-wrap:normal")
            Else
                rs.Close()

“类型”列是外键。在此表中只有两行ID和Type。如何显示Type而不是ID？

尝试此查询...

SELECT a.ID, Customer, ContactPerson, Model, SerialNo, Status, b.Type, Value, InvoiceNo
     FROM BackBillCustomer a inner join ForegnKeyTableName b  on a.Type=B.id and Status = 'Open'

在gridview中显示文本而不是外键的ID
