To map a class to multiple tables with the same update mode or excluded or output callback options (for example, to split features from the class to different tables because of size), add a table to the class map.
To add additional tables to a class map
Right-click on the class to which you want to add additional tables and then select the Add Additional Tables to Class Map command from the popup menu that is displayed. (This command is disabled if the selected class has subclasses mapped to the same table. For details, see "Mapping Subclasses to a Class Map", earlier in this chapter.)
A new row is then created below the selected row, with the cell in the Table column highlighted with a bright yellow background, indicating that it is in edit mode and a value is required. A link icon at the left of the name in the Class column indicates that the tables are linked to the same class map. The update modes and excluded and output callback options must be the same.
In the Table column, specify the name of the table to which the class is mapped. The name must be valid in the relational database and has a maximum length of 80 characters.
