尝试这样的事情
Try
Dim sql As String = "SELECT first_row FROM test_table WHERE id = 1"
Dim cmd as OleDbCommand
cmd = New OleDbCommand(sql, Reconnect)
Dim itmReader as SqlDataReader
itmReader = cmd.ExecuteReader
If itmReader.Read Then
Dim firstRowData as String
firstRowData = itmReader.Item("first_row")
MessageBox.Show(firstRowData)
End If
Catch ex As Exception
MsgBox(ex.Message)
End Try
