Data files can be structured in a variety of ways. The HPL supports data-file records of the following formats:
You can define new format components at any time. Also, you can test your format before you actually load or unload data. For information about testing a format, see Previewing Data-File Records.
The ipload utility includes options that let you modify the data before it is inserted into the database. For information about how to modify data, see Format Options.
The ipload utility stores information about formats in the formatitem and format tables of the onpload database. For more information about the formatitem and format tables, see page Formatitem Table and page Formats Table, respectively.
