使用VB.net列出SQLite資料的範例(select)
********************************************
Private Sub ListData_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles ListData.Click
Try
Dim zSQLFile As String = "Data Source=C:\SQLite檔案存放資料夾\NewDB3.db3"
'連接資料庫
Dim oConn As New SQLiteConnection(zSQLFile)
oConn.Open()
'執行SQL指令
Dim zSQL As String = "SELECT * from test "
Dim oCmd As SQLiteCommand = New SQLiteCommand(zSQL, oConn)
'將執行結果放到DataReader
Dim oDR As SQLiteDataReader = oCmd.ExecuteReader()
'將Dataview的資料顯示在ListBox1上
ListBox1.Items.Clear()
While oDR.Read()
'ListBox1.Items.Add(String.Format("{0},{1},{2}", oDR(0), oDR(1), oDR(2)))
ListBox1.Items.Add(String.Format("{0},{1},{2}", oDR("oid"), oDR("word"), oDR("denotation")))
End While
lblMsg.Text = "Data Added to ListBox ready!!!"
oCmd.Dispose()
oConn.Close()
Catch ex As Exception
lblMsg.Text = ex.Message
End Try
End Sub
