ReadOnly Property AutoCreateOption As AutoCreateOption
| Type | Description |
|---|---|
| AutoCreateOption |
An AutoCreateOption value that specifies which operations are 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.
|
In most cases, this property is initialized in the constructor of the class that implements the IDataStore interface.
