VB.NET Execute Multiple SQL Statements using OleDb command

[mnarewec]

I would like to execute multiple SQL Statement using OleDB command but its coming up with error " Characters found after end of statement"

Below is my pieces of code.

Public Class DalOleDb
Public Class DalOleDb
Private _dss As DataSet
    Private _daa As OleDbDataAdapter
    Private _cnn As OleDbConnection
    Private _cmd As OleDbCommand
    Private _drr As OleDbDataReader
    Private _cnnStr As String

    Public Sub New()
        Try
            cnn = New OleDbConnection(cnnString)
            daa = New OleDbDataAdapter()
            dss = New DataSet()
            cmd = New OleDbCommand()
        Catch ex As Exception
            Throw New Exception(ex.Message)
        End Try
    End Sub

Sub DeleteBatch()
Try

'Delete batches related to this company
            sb = sb.Append("DELETE FROM BATCH_HEADERS WHERE BH_CUSTNUMB=" & "'" & CompanyCode & "'")
            sb = sb.Append(";")
            sb = sb.Append("DELETE FROM BATCH_DETAILS WHERE BD_CUSTNUMB=" & "'" & CompanyCode & "'")
            sb = sb.Append(";")
            sb = sb.Append("DELETE FROM BATCH_HEADERS_BACKUP WHERE BHB_CUSTNUMB=" & "'" & CompanyCode & "'")
            sb = sb.AppendLine
            sb = sb.Append("DELETE FROM BATCH_DETAILS_BACKUP WHERE BDB_CUSTNUMB=" & "'" & CompanyCode & "'")
            sb = sb.Append(";")
ExecuteSQL(sb.ToString())

  Catch ex As Exception
            Throw New Exception(ex.Message)
        Finally
        End Try
  End Sub


Sub ExecuteSQL(ByRef SQLStatement As String)
        Try
            cmd.CommandText = SQLStatement
            cmd.Connection = cnn
            cnn.Open()
            cmd.ExecuteNonQuery()
        Catch ex As Exception
            Throw New Exception(ex.Message)
        Finally
            cnn.Close()
        End Try
    End Sub

End Class

plz change code

sb = sb & "DELETE FROM BATCH_HEADERS WHERE BH_CUSTNUMB=" & "'" & CompanyCode & "';"

sb = sb & "DELETE FROM BATCH_DETAILS WHERE BD_CUSTNUMB=" & "'" & CompanyCode & "';"
sb = sb & "DELETE FROM BATCH_HEADERS_B ACKUP WHERE BHB_CUSTNUMB=" & "'" & CompanyCode & "';"
sb = sb & "DELETE FROM BATCH_DETAILS_B ACKUP WHERE BDB_CUSTNUMB=" & "'" & CompanyCode & "';"

I recommend using Parameters instead of dynamically building your query string.
See http://bytes.com/topic/net/insights/...e-your-program for an example.
