Like the Import utility, the LAOD utility is designed to read data directly from an external file and store it in a specific table. However, unlike when the import utility is used, when the Load utility is used the table to which data is to be copied must already exist in the database before the load operation is initiated.



DB2MOVE utility

Its easy to see how the export utility can be used together with the import utility or load utility to copy a table from one database to another, but what if we want to copy several tables or an entire database?

In this case, data can be copied table by table using export/import/load but a more efficient way to copy an entire DB2 database is by using the DB2MOVE utility.

One way to copy data from an external file to a database is by using DB2's import utility; the import utility is desgined to read data directly from an external file (provided the file is written in a format that is supported by DB2) and insert it in a specific table or updatable view.

The export utility is designated to extract data from a DB2 database table or view and externalize into a file using the file formats like DEL (Delimited ASCII), WSF (worksheet format), IXF (PC Information Exchange Format). Such files can then be used to provide data values to other databases and software applications such as spreadsheets and word processors.
