mysql - VB.Net MySql命令参数MD5

Question

是否可以执行这样的命令？

select * from tbl where col1=somefunction(@param1)

或者参数是否会影响函数？到目前为止，我未能成功使命令生效。

如果这需要任何进一步的解释，请告诉我，在此先感谢您!

在 VBNet 中:

Shared Sub Main()
    con = New MySqlConnection("Your ConnectionString") 

    Dim cmd As New MySqlCommand("select * from tbl where col1 = somefunction(@param1)", con)
    cmd.Parameters.AddWithValue("param1","value HEre")

    Try
        con.Open()
        Dim reader As MySqlDataReader = cmd.ExecuteReader()
        While reader.Read()
            Console.WriteLine("{0}", reader.GetString(0))
        End While
        reader.Close()
    Finally
        con.Close()
    End Try
End Sub
