Transient

Specifies whether the property is stored in the database. Applies only to persistent classes.

Usage

To specify that the property is not stored in the database, use the following syntax:

Property name As classname [ Transient ];

Otherwise, omit this keyword or place the word Not immediately before the keyword.

Details

In the case of a persistent class, specifies that the property is not stored in the database.

Note that InterSystems IRIS validates transient properties in the same way as other properties. For example, when you try to save the object, the system validates all its properties, including any transient properties.

In a subclass, you can mark a non-transient property as transient, but you cannot do the reverse.

Default

If this keyword is omitted, the property is not transient.
