AutoCreateOption Enum

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.v21.1.dll

Declaration

public enum AutoCreateOption

Members

Name Description
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.

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.

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.

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.

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 Session.AutoCreateOption property.
