SELECT * Not Working For Access Database

[-RaJ-]

for the first time i am havin this kind of issue, i tried some google'in but of none help.

    Private Sub frmMain_Load(ByVal sender As Object, ByVal e As System.EventArgs) Handles Me.Load
        Log("Application Started Successfully")

        Log("Attempting To Connect To Database", True)

        If dbConnect(Application.StartupPath & "\myDatabase.mdb") Then
            Log("Successfully Connected To Database", True)
        Else
            MessageBox.Show("Unable To Connect To Database Critical Error", APP_NAME, MessageBoxButtons.OK, MessageBoxIcon.Error)
            Application.Exit()
        End If

        'Using cmd As New OleDb.OleDbCommand("INSERT INTO MY_SETTING VALUES(1, 'TEST', 'TEST')", Conn)
        '    Debug.Print("Record's Affected : " & cmd.ExecuteNonQuery())
        'End Using

        Using cmd As New OleDbCommand("SELECT * from MY_SETTING;", Conn)
            Debug.Print("Total ID : " & cmd.ExecuteNonQuery())
        End Using

    End Sub

The weird problem is INSERT is working but Select is not working!

what do you meant by "it's not working" ??? Did you get toast when you asked for OJ? Did your door suddenly fall off the hinges? Did the tires fall off your car? Or did your arms fall off? We are not mind readers. People seem to think we are for some reason... I don't know why... but it's a rumour that's been around for almost as long as I can remember. Not quite sure what you're expecting to happen... perhaps if you removed the eels from your hover craft...

by not working i meant to say is its showing 0 record's affected for that query command

        Using cmd As New OleDbCommand("SELECT * from MY_SETTING;", Conn)
            Debug.Print("Total ID : " & cmd.ExecuteNonQuery())
        End Using

it must show some positive non zero values, in other word's its not able to select it !! to data reader

DataReader is showing as

.hasRow = False


this error has never happened to me before!

[techgnome]

That's because you're using the ExecuteNonQuery ... there were NO ROWS affected... you didn't CHANGE any rows... so yeah, that's what I would expect. Your datareader is showing no rows because you used the ExecuteNonQuery... and not the ExecuteReader...
ExecuteNonQuery Documentation:
http://msdn.microsoft.com/en-us/libr...enonquery.aspx

ExecuteReader Documentation:
http://msdn.microsoft.com/en-us/libr...utereader.aspx

Might want to brush up on what each one does...

What is confusing is, do you want to return rows or a count of rows?

Seeing this yet at the same time Total mixed with ID does not makes sense

Debug.Print("Total ID : " & cmd.ExecuteNonQuery())

Looks like you want total row count which would be done as follows.

cmd.CommandText = "SELECT COUNT(*) From MY_SETTING"
Dim CustCount = CLng(cmd.ExecuteScalar)

If you want rows back and not a count then use cmd.ExecuteReader.
