ConnectionPool

Manager that handles opening/retrieving database connections.

It's a facade to the actual Doctrine DBAL DriverManager that implements TYPO3 specific functionality like mapping individual tables to different database connections.

getConnectionForTable() is the only supported way to get a connection that honors the table mapping configuration.

Methods

getConnectionByName()

Creates a connection object based on the specified identifier.

public getConnectionByName(string $connectionName) : Connection

This method should only be used in edge cases. Use getConnectionForTable() so that the tablename<>databaseConnection mapping will be taken into account.

Parameters
$connectionName : string
Tags
throws
Exception
Return values
Connection

getConnectionForTable()

Creates a connection object based on the specified table name.

public getConnectionForTable(string $tableName) : Connection

This is the official entry point to get a database connection to ensure that the mapping of table names to database connections is honored.

Parameters
$tableName : string
Return values
Connection

getConnectionMiddlewareConfigurationArrayForLowLevelConfiguration()

public getConnectionMiddlewareConfigurationArrayForLowLevelConfiguration() : array<string|int, mixed>
Internal

only for ext:lowlevel usage to retrieve configuration overview. *

Return values
array<string|int, mixed>

getConnectionNames()

Returns an array containing the names of all currently configured connections.

public getConnectionNames() : array<string|int, mixed>

This method should only be used in edge cases. Use getConnectionForTable() so that the tablename<>databaseConnection mapping will be taken into account.

Internal
Return values
array<string|int, mixed>

getQueryBuilderForTable()

Returns the connection specific query builder object that can be used to build complex SQL queries using and object-oriented approach.

public getQueryBuilderForTable(string $tableName) : QueryBuilder
Parameters
$tableName : string
Return values
QueryBuilder

registerDoctrineTypes()

Register custom and override Doctrine data types implemented by TYPO3.

public registerDoctrineTypes() : void

This method is needed by Schema parser to register the types as it does not require a database connection and thus the types don't get registered automatically.

Internal

resetConnections()

Reset internal list of connections.

public resetConnections() : void

Currently, primarily used in functional tests to close connections and start new ones in between single tests.

getConnectionParams()

protected getConnectionParams(string $connectionName) : array<string|int, mixed>
Parameters
$connectionName : string
Return values
array<string|int, mixed>

getDatabaseConnection()

Creates a connection object based on the specified parameters

protected getDatabaseConnection(string $connectionName, array<string|int, mixed> $connectionParams) : Connection
Parameters
$connectionName : string
$connectionParams : array<string|int, mixed>
Return values
Connection

getDriverMiddlewares()

Return any doctrine driver middlewares, that may have been set up in: - for all configured connections - $GLOBALS['TYPO3_CONF_VARS']['DB']['Connections']['Default']['driverMiddlewares'] for a specific connection

protected getDriverMiddlewares(string $connectionName, array<string|int, mixed> $connectionParams) : array<string|int, mixed>
Parameters
$connectionName : string
$connectionParams : array<string|int, mixed>
Return values
array<string|int, mixed>

getOrderedConnectionDriverMiddlewareConfiguration()

protected getOrderedConnectionDriverMiddlewareConfiguration(string $connectionName, array<string|int, mixed> $connectionParams) : array<non-empty-string, array{target: class-string, disabled: bool, after: string[], before: string[], type: string}>
Parameters
$connectionName : string
$connectionParams : array<string|int, mixed>
Return values
array<non-empty-string, array{target: class-string, disabled: bool, after: string[], before: string[], type: string}>
