Expand description
Creates constraints for any structure that can create a database connection and execute SQL statements
Required Methods
fn get_database_backend(&self) -> DbBackend
fn get_database_backend(&self) -> DbBackend
Fetch the database backend as specified in DbBackend. This depends on feature flags enabled.
Execute a Statement
Execute a Statement and return a query
Provided Methods
fn support_returning(&self) -> bool
fn support_returning(&self) -> bool
Check if the connection supports RETURNING
syntax on insert and update
fn is_mock_connection(&self) -> bool
fn is_mock_connection(&self) -> bool
Check if the connection is a test connection for the Mock database
