要連接網絡對接數據庫,可以使用以下步驟:
Imports System.Data.SqlClient
Dim connectionString As String = "Server=myServerAddress;Database=myDataBase;User Id=myUsername;Password=myPassword;"
Dim connection As New SqlConnection(connectionString)
connection.Open()
Dim sql As String = "SELECT * FROM myTable"
Dim command As New SqlCommand(sql, connection)
Dim reader As SqlDataReader = command.ExecuteReader()
While reader.Read()
'處理查詢結果的邏輯
End While
reader.Close()
connection.Close()
以上是基本的連接網絡對接數據庫的步驟,具體的操作可以根據實際需求進行調整和擴展。
