db error

I'm getting this error when I hit this line objCommand.ExecuteNonQuery()

An unhandled exception of type 'System.Data.OleDb.OleDbException' occurred in system.data.dll

Code:

---

Dim sqlCmd As String = "insert into DBATEST.PCMS_Billing_Period (begin_billing_date,end_billing_date,credit_card_no,employee_work_unit,status_ind) "
        sqlCmd = sqlCmd & "values (?,?,?,?,?)"
        Dim objCommand As New OleDbCommand(sqlCmd, objConnection)
        objCommand.Parameters.Add("@begin_billing_date", System.Data.OleDb.OleDbType.Date).Value = dp1.Value
        objCommand.Parameters.Add("@end_billing_date", System.Data.OleDb.OleDbType.Date).Value = dp2.Value
        objCommand.Parameters.Add("@credit_card_no", System.Data.OleDb.OleDbType.Char, 16).Value = txtCreditNo.Text
        objCommand.Parameters.Add("@employee_work_unit", System.Data.OleDb.OleDbType.Char, 4).Value = txtWorkUnit.Text
        objCommand.Parameters.Add("@status_ind", System.Data.OleDb.OleDbType.Char, 1).Value = Post_to_Int
        objConnection.Open()
        objCommand.ExecuteNonQuery()
        objConnection.Close()

Just wondering....

Shouldn't the ?,?,?,? in command string be replaced with @end_billing_date, @credit_card_no, @employee_work_unit, @status_ind

I've been using that code on other apps and it has been working fine...till now!

try using your table name like this

VB Code:

[DBATEST.PCMS_Billing_Period]

usually , this error caused by connection strings , SQL string(misspelled table name ..)

thanks guys...I put the DB connection in a Try, Catch block and got a more detailed error message...it was an inccorect table name..
