Property Value
| Type | Description |
|---|---|
| AutoCreateOption | An AutoCreateOption enumeration value that specifies the action which is performed when a data store is accessed for the first time. |
Available values:
| 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. |
