If you want to create a table that is similar to a table in your IBM® database, you can base the new table on the existing table definition.
To create a table from an existing table:
The IBM Table Designer opens, with the information for the selected table displayed in the fields of the designer. The value in the Table name field contains an incremental numeric suffix.
For detailed information about the fields in the designer views, see IBM Table Designer.
The table is created and added to your database.
