Flat file generation integrity ideas...I do not see how the file can get "scrambled". You write it out ok.
The ftp is guaranteed.
So what is the problem.

I will go along with the suggestion to zip it. It saves on the ftp time and also gives you some protection.

  I have to create packages that will generate several flat files of data from tables that will be sent to other systems to be processed.

  I am looking for ideas on how to ensure data integrity in the flat files.

  For example, the expected record count is stored on the first line of the file to ensure that the correct amount of records was received.

  The systems group is chartered to ensure the flat files are correctly FTPed between systems, so that's covered.

  I just worry that if "somehow" a flat file is scrambled then the scrambled data is loaded into the database, therefore corrupting it.

  At this phase, XML is not an option

  I keep thinking that some sort of CRC should be stored with each line in the flat file. And then before the line is loaded into the database, the CRC is compared against the generated CRC of the just read line. Has anyone done anything like this? Any examples out there?

  Many TIA!!
