Метод	Описание
__construct ( string \| array $fields, array \| Cake\Database\ExpressionInterface $values, array $types = [], string $conjunction = '=' )	Constructor
isMulti ( ) : boolean	Determines if each of the values in this expressions is a tuple in itself
sql ( ValueBinder $generator ) : string	Convert the expression into a SQL fragment.
traverse ( callable $callable ) : void	Traverses the tree of expressions stored in this object, visiting first expressions in the left hand side and then the rest.

Метод	Описание
_bindValue ( ValueBinder $generator, mixed $value, string $type ) : string	Registers a value in the placeholder generator and returns the generated placeholder
_stringifyValues ( ValueBinder $generator ) : string	Returns a string with the values as placeholders in a string to be used for the SQL version of this expression
_traverseValue ( mixed $value, callable $callable ) : void	Conditionally executes the callback for the passed value if it is an ExpressionInterface

Constructor

public __construct ( string \| array $fields, array \| Cake\Database\ExpressionInterface $values, array $types = [], string $conjunction = '=' )
$fields	string \| array	the fields to use to form a tuple
$values	array \| Cake\Database\ExpressionInterface	the values to use to form a tuple
$types	array	the types names to use for casting each of the values, only one type per position in the value array in needed
$conjunction	string	the operator used for comparing field and value

Registers a value in the placeholder generator and returns the generated placeholder

protected _bindValue ( ValueBinder $generator, mixed $value, string $type ) : string
$generator	Cake\Database\ValueBinder	The value binder
$value	mixed	The value to bind
$type	string	The type to use
Результат	string	generated placeholder

Returns a string with the values as placeholders in a string to be used for the SQL version of this expression

protected _stringifyValues ( ValueBinder $generator ) : string
$generator	Cake\Database\ValueBinder	The value binder to convert expressions with.
Результат	string

Conditionally executes the callback for the passed value if it is an ExpressionInterface

protected _traverseValue ( mixed $value, callable $callable ) : void
$value	mixed	The value to traverse
$callable	callable	The callable to use when traversing
Результат	void

Determines if each of the values in this expressions is a tuple in itself

public isMulti ( ) : boolean
Результат	boolean

Convert the expression into a SQL fragment.

public sql ( ValueBinder $generator ) : string
$generator	Cake\Database\ValueBinder	Placeholder generator object
Результат	string

Callback function receives as its only argument an instance of an ExpressionInterface

public traverse ( callable $callable ) : void
$callable	callable	The callable to apply to sub-expressions
Результат	void
