Vb.Net select tables

Question

我是Vb.NET中的新成员，我在这里有一个代码，我从例子中选择了一个表。我想要的是我想选择另一个表格..我只想选择除用户以外的另一个表格，因为我有另一个表格绑定/调用另一个表格。

我该怎么做？

Dim connection As MySql.Data.MySqlClient.MySqlConnection 
    Dim adapter As MySql.Data.MySqlClient.MySqlDataAdapter 
    Dim commandBldr As MySql.Data.MySqlClient.MySqlCommandBuilder 
    Dim command As MySql.Data.MySqlClient.MySqlCommand 
    Dim dataSet As System.Data.DataSet 
    Dim bindingSource1 As BindingSource 

    Private Sub btConnect_Click(sender As System.Object, e As System.EventArgs) Handles btConnect.Click 
     connection = New MySql.Data.MySqlClient.MySqlConnection 
     connection.ConnectionString = "user id=" & tbUserName.Text + "; password=" & tbPassword.Text & "; server=" & tbServer.Text & "; database=" & tbDatabase.Text & "; pooling=false;" 

     Try 
      connection.Open() 
      adapter = New MySql.Data.MySqlClient.MySqlDataAdapter 
      commandBldr = New MySql.Data.MySqlClient.MySqlCommandBuilder 
      command = New MySql.Data.MySqlClient.MySqlCommand 
      dataSet = New System.Data.DataSet 
      bindingSource1 = New BindingSource 

      commandBldr.DataAdapter = adapter 
      command.CommandText = "SELECT userID,pin, print1, print2 from users" 
      command.Connection = connection 
      adapter.SelectCommand = command 
      adapter.Fill(dataSet) 
      bindingSource1.DataSource = dataSet.Tables(0) 
      dgvUsers.DataSource = bindingSource1 

     Catch ex As Exception 

     End Try 

我做这个了... ...

dataSet = New DataSet 
adapter.SelectCommand.CommandText = "select * from dtr" 
adapter.Fill(dataSet)

你应该能够改变你的例子查询的命令文本匹配你想拉回来的。例如：

command.CommandText = "SELECT col1, col2 from newTable"
