Driver

A Driver creates and releases {@link DatabaseConnection | database connections} and is also responsible for connection pooling (if the dialect supports pooling).

interface Driver {

acquireConnection(): Promise<DatabaseConnection>;

beginTransaction(connection: DatabaseConnection, settings: TransactionSettings): Promise<void>;

commitTransaction(connection: DatabaseConnection): Promise<void>;

destroy(): Promise<void>;

init(): Promise<void>;

releaseConnection(connection: DatabaseConnection): Promise<void>;

rollbackTransaction(connection: DatabaseConnection): Promise<void>;

}

§Methods

acquireConnection(): Promise<DatabaseConnection>

[src]

Acquires a new connection from the pool.

beginTransaction(connection: DatabaseConnection, settings: TransactionSettings): Promise<void>

[src]

Begins a transaction.

commitTransaction(connection: DatabaseConnection): Promise<void>

[src]

Commits a transaction.

destroy(): Promise<void>

[src]

Destroys the driver and releases all resources.

init(): Promise<void>

[src]

Initializes the driver.

After calling this method the driver should be usable and acquireConnection etc. methods should be callable.

releaseConnection(connection: DatabaseConnection): Promise<void>

[src]

Releases a connection back to the pool.

rollbackTransaction(connection: DatabaseConnection): Promise<void>

[src]

Rolls back a transaction.
