Question

对不起那个菜鸟问题..但这就是我做的事情

Dim cmd As New SqlCommand("Declare @mychar varchar(60) " & _
                              "Set @mychar = '" & TextBox2.Text & "'" & _
                              "Select * from @mychar", conn)
    Dim rdr As SqlDataReader = cmd.ExecuteReader
    While rdr.Read()
        ListView2.Items.Add(rdr("Account"))
    End While
    rdr.Close()

但是我收到一条错误，上面写着“必须声明表变量”@mychar“。”怎么了？或者这不仅仅是可能的吗？提前谢谢..

Answer 1

Dim cmd As New SqlCommand(" Select * from " & TextBox2.Text & " ", conn)
    Dim rdr As SqlDataReader = cmd.ExecuteReader
    While rdr.Read()
        ListView2.Items.Add(rdr("Account"))
    End While
    rdr.Close()

是否可以设置选择表的参数？
