When the data source is not an Informix database, you must find a way to convert it into a flat ASCII file; that is, a file of printable data in which each line represents the contents of one table row.
After you have the data in an ASCII file, you can use the dbload utility to load it into a table. For more information on dbload, see the IBM Informix: Migration Guide. The LOAD statement in DB-Access can also load rows from a flat ASCII file. For information about the LOAD and UNLOAD statements, see the IBM Informix: Guide to SQL Syntax.
After you have the data in a file, you can use external tables to load it into a table. For more information on external tables, see your IBM Informix: Administrator's Guide.
