Handles Me.Load
Dim ConnectionString As String
Dim cn As New SqlConnection()
Dim cmd As New SqlCommand, dr As SqlDataReader = Nothing
Try
'連線至SQL Server
ConnectionString = "Data Source=執行個體名稱;" & _
"Initial Catalog=資料庫名稱;" & _
"User ID=帳號;Password=密碼;"
cn.ConnectionString = ConnectionString
cn.Open()
'取得資料
cmd.Connection = cn
cmd.CommandText = "sql查詢語法"
dr = cmd.ExecuteReader()
'讀取並寫入資料至檔案
Dim sw As New StreamWriter("檔案路徑", True, Encoding.Default)
Do While dr.Read()
sw.WriteLine(dr("欄位名稱").ToString())
Loop
sw.Close()
Catch ex As Exception
'錯誤處理
Label1.Text = ex.Message
Finally
'不管有沒有錯誤,結束時都要關閉連接
If Not dr Is Nothing AndAlso Not dr.IsClosed Then dr.Close()
If Not cn Is Nothing AndAlso cn.State <> _
Data.ConnectionState.Closed Then cn.Close()
