AutoCreateOption Enumeration

Lists the values that specify the action which is performed when a session is connected to a data store.

Namespace:DevExpress.Xpo.DB
Assembly:DevExpress.Data.v19.1.dll

Expanded Public Members

Show: Inherited
  Name Description
Public field DatabaseAndSchema A session will try to automatically create the database if it doesn't exist. It will also create or update the database schema for any persistent classes currently being used.
Public field None A session will not automatically create the database or update the database schema. The database schema is still queried and checked to match the currently used persistent class metadata.
Public field SchemaAlreadyExists A session will never query the database for schema to validate against persistent class metadata. This will suppress the SchemaCorrectionNeededException, but a database error may occur during data operations if the schema is not compatible with run-time persistent classes metadata.
Public field SchemaOnly A session will automatically create or update the database schema for the persistent classes currently being used. If the database doesn't exist, it won't be created by a session.
Top

Expanded Remarks

The values listed by this enumeration can be used when instantiating a Data Access Layer. Additionally, you can set the mode for a specific Session, using the DevExpress.Xpo.Session.AutoCreateOption property.
