  • SQL optimization in COBOL400

    I am using an SQL in Cobol 400 to delete around 100 million records out of 200 million records based on a date. What is the best way to delete this much data in one stretch? The file has key as date. My sql would look like Delete from FileA where Date < 'some date'

  • We had a security audit and one of the requirement was to raise an alarm whenever any user does a data extract.

    Is it possible to raise a alert whenever a user does a data extract using ODBC or DTF.Using CL program or any other way.
