What happened wrong when you used the AT command? I would create a blank MDB, link the necessary tables to it so that the data can be uploaded and have an autoexec macro that loads the data. I would then write the batch that runs the SQL queries from Oracle and then opens this new MDB so that it auto loads the data. After that, set up AT to run the batch:
AT \\ServerName 0100a /every: m,t,w,th,f,s,su "C:\MyPath\MyBatchFile.bat"
I have several batches that kick off run through AT. Terry M. Hoey
