To use with Delta imports from SQL – check if there are any lines in the Delta table before running an Import. By only running delta imports when there’s actually something to do you can save on time and transaction log space.

Const DB_CONNECT_STRING = “Provider=SQLOLEDB;Data Source=(local);Initial Catalog=DB-name;Integrated Security=SSPI”

Function DeltaImportsPending(Delta_Table)
  Dim objDB, sqlQuery, recordset

  Set objDB = CreateObject(“ADODB.Connection”)
  Set recordset = CreateObject(“ADODB.Recordset”)

  objDB.Open DB_CONNECT_STRING
  sqlQuery = “SELECT COUNT (*) AS num FROM ” & Delta_Table

  recordset.Open sqlQuery, objDB

  If recordset.Fields(“num”) > 0 Then
    DeltaImportsPending = TRUE
  Else
    DeltaImportsPending = FALSE
    WriteLog(“No pending delta imports – stopping.”)
  End If

  objDB.Close
