Specifying Domain properties
Specify the properties for the new Domain according to your needs. The detailed description is given below.
Name
Specify a name for the domain.
Owner
Select the owner of the Domain from the drop-down list. By default, only the owner of an object can perform various operations with the object. In order to allow other users to operate it, privileges must be granted. (However, users that have the superuser attribute can always access any object.)
Comment
Supply a comment to the Domain if necessary.
Base Type
Select the underlying data type for the Domain. This may include array specifiers.
The Length, Precision and Number of Array Dimensions fields allow you to specify the domain properties respectively.
Not Null
The checkbox indicates that the values of the Domain are not allowed to be null.
Default Value
The field is used to specify a default value for the columns of the domain data type. The Default Value field may contain any variable-free expression (however, subqueries are not allowed). The data type of the default expression must match the data type of the domain. If no default value is specified then the default value is the null value.
