Описание методов

__construct() публичный Метод

Constructor.
См. также: lithium\data\source\Database::__construct()
См. также: lithium\data\Source::__construct()
См. также: lithium\data\Connections::add()
public __construct ( array $config = [] ) : void
$config array The available configuration options are the following. Further options are inherited from the parent classes. Typically, these parameters are set in `Connections::add()`, when adding the adapter to the list of active connections. - `'database'` _string_: Defaults to in-memory database `':memory:'`.
Результат void

_buildColumn() защищенный Метод

Helper for Database::column().
См. также: lithium\data\Database::column()
protected _buildColumn ( array $field ) : string
$field array A field array.
Результат string SQL column string.

_column() защищенный Метод

Converts database-layer column types to basic types.
protected _column ( string $real ) : string
$real string Real database-layer column type (i.e. "varchar(255)")
Результат string Abstract column type (i.e. "string")

_execute() защищенный Метод

Execute a given query.
См. также: lithium\data\source\Database::renderCommand()
protected _execute ( string $sql, array $options = [] ) : Result
$sql string The sql string to execute
$options array No available options.
Результат lithium\data\source\Result Returns a result object if the query was successful.

_insertId() защищенный Метод

Gets the last auto-generated ID from the query that inserted a new record.
protected _insertId ( object $query ) : mixed
$query object The `Query` object associated with the query which generated
Результат mixed Returns the last inserted ID key for an auto-increment column or a column bound to a sequence.

connect() публичный Метод

Connects to the database by constructing DSN string and creating a PDO intance using the parent class. Will set specific options on the connection as provided.
public connect ( ) : boolean
Результат boolean Returns `true` if a database connection could be established, otherwise `false`.

describe() публичный Метод

A column type may not always be available, i.e. when during creation of the column no type was declared. Those columns are internally treated by SQLite3 as having a NONE affinity. The final schema will contain no information about type and length of such columns (both values will be null).
public describe ( mixed $entity, array $fields = [], array $meta = [] ) : array
$entity mixed Specifies the table name for which the schema should be returned, or the class name of the model object requesting the schema, in which case the model class will be queried for the correct table name.
$fields array Any schema data pre-defined by the model.
$meta array
Результат array Returns an associative array describing the given table's schema, where the array keys are the available fields, and the values are arrays describing each field, containing the following keys: - `'type'`: The field type name

disconnect() публичный Метод

Disconnects the adapter from the database.
public disconnect ( ) : boolean
Результат boolean True on success, else false.

enabled() публичный статический Метод

Check for required PHP extension, or supported database feature.
public static enabled ( string $feature = null ) : boolean
$feature string Test for support for a specific feature, i.e. `'transactions'`.
Результат boolean Returns `true` if the particular feature (or if Sqlite) support is enabled, otherwise `false`.

encoding() публичный Метод

Gets or sets the encoding for the connection.
public encoding ( string $encoding = null ) : mixed
$encoding string If setting the encoding, this is the name of the encoding to set, i.e. `'utf8'` or `'UTF-8'` (both formats are valid).
Результат mixed If setting the encoding; returns `true` on success, or `false` on failure. When getting, returns the encoding as a string.

error() публичный Метод

Retrieves database error message and error code.
public error ( ) : array
Результат array

sources() публичный Метод

Returns the list of tables in the currently-connected database.
public sources ( string $model = null ) : array
$model string The fully-name-spaced class name of the model object making the request.
Результат array Returns an array of objects to which models can connect.
