Error Deleting Table from Access DB

[Guest]

Not sure this is the right place for this questions, but here goes:

I get an error message when deleting an table from a Access database.

The code is as follows and the error message is after it.


***************** Start Code ********************
<%@ import Namespace="System.Data" %>
<%@ import Namespace="System.Data.Oledb" %>

Sub Page_Load(Sender as object, e as EventArgs)
if not isPostBack then
'************* Delete previous orders ********
Dim Con As OleDbConnection = New OleDbConnection
Dim DA As OleDbDataAdapter = New OleDbDataAdapter
Dim ConnectString, delCmd, x as String

x = Server.Mappath("\ASPClass\FinalProj\DB.mdb")

ConnectString = "Provider=Microsoft.Jet.OLEDB.4.0;Data Source=" & x

Con.ConnectionString = ConnectString


delCmd = "DELETE * FROM ORDERS"

DA.DeleteCommand = New OleDbCommand(delCmd, Con)
Con.Open
DA.DeleteCommand.ExecuteNonQuery()
'*********************************************
end if
End Sub
******************** End Code ********************

Thank you for your help.

delCmd = "DELETE * FROM ORDERS"This looks like an SQL command to delete all rows from the orders table
(not the orders table itself.) The proper syntax is without the *:

DELETE FROM ORDERS

If you would rather delete a single order only, try something like:

DELETE FROM ORDERS WHERE ORDERNR = 'MyOrderNumber'
