I've not done this directly, but indirectly in AcuCOBOL by creating an XFD (External file definition) and then parsing the XFD to create SQL commands to CREATE equivalent tables. AcuCOBOL's XFD feature allowed me to identify DATEs and eliminated the need to parse the COBOL records directly. Once you know the name and datatype of the elementary data items, creating the SQL commands is pretty straightforward.
