Using the VARRAY Designer

The VARRAY Designer creates new VARRAY types.

The controls in the VARRAY Designer are as follows:

Control	Description
Schema name	Select the schema for the new type. The list contains all the schemas that are available to you as defined in the Filters Tab on the Connection Dialog. By default, the schema for the new VARRAY type is the one you have logged in with. If that schema was not defined in the filter tab, then the default schema is the first schema in the sorted list of available schemas.
Type name	Displays the name of the new VARRAY type. By default, the name is generated in the format VARRAYX where X can be any number.
Limit	The maximum size of the VARRAY type. Default is 80.
Element Properties	This section enables you to specify properties for the element of the VARRAY type. The first property, Type, is constant. Other properties change based on the type. Type: The data type of the element of the VARRAY type. The list contains all the database predefined types, ANSI types, and available user-defined types. When the type changes, other attribute properties change. You cannot create attributes of these data types: LONG, LONG RAW, ROWID, and UROWID. Size: Represents the size of Character types. Default is 20. Precision: For types DECIMAL, NUMBER, NUMERIC: Represents precision for numeric types. You can specify the precision for the type in this field.
