基于mysql的数据网格

我正试图使用这段代码在网格上显示，其中信息是根据前面标记的字段进行研究的

SQL = "SELECT * FROM funcionario WHERE setor ='" + TxtPesq.Text + "'"
                myCommand.Connection = conn
                myCommand.CommandText = SQL
                myAdapter.SelectCommand = myCommand
                myAdapter.Fill(myData)
                DataGridView1.DataSource = myData

• 使用

  使用
  语句正确处理对象

• 参数化查询以避免sql注入

完整代码

Dim dSet As New Dataset
Dim SQL AS String= "SELECT * FROM funcionario WHERE setor = @setor"
Using conn As New MySqlConnection("connectionStr HERE")
    Using myCommand As New MysqlCommand()
        With MyCommand
            .Connection = conn
            .CommandText = SQL
            .CommandType = CommandType.Text
            .Parameters.AddWithValue("@setor", TxtPesq.Text) 
        End With
        Using myAdapter As New MySQLDataAdapter(myCommand)
            Try
                myAdapter.Fill(dset)
                DataGridView1.DataSource = dset.tables(0)
            Catch(ex as MySQLException)
                Msgbox (ex.Messge)
            End Try
        End Using
    ENd Using

到底是什么不起作用？请提供更多详细信息。您好，您能检查mydata对象中正在提交的数据吗。。。？
