All Classes | Properties | Methods

Inheritance	Yiisoft\Db\Expression\Function\MultiOperandFunction
Implements	Yiisoft\Db\Expression\ExpressionInterface

Base class for functions that operate on multiple operands with the same type.

It provides methods to add operands and retrieve them.

See also Yiisoft\Db\Expression\Function\Builder\MultiOperandFunctionBuilder base class for building SQL representation of multi-operand function expressions.

Protected Properties

Property	Type	Description	Defined By
$operands	array	List of operands.	Yiisoft\Db\Expression\Function\MultiOperandFunction

Method	Description	Defined By
__construct()		Yiisoft\Db\Expression\Function\MultiOperandFunction
add()		Yiisoft\Db\Expression\Function\MultiOperandFunction
getOperands()		Yiisoft\Db\Expression\Function\MultiOperandFunction

$operands protected property

List of operands.

protected array $operands = []

__construct() public method

public mixed __construct ( mixed $operands )
$operands	mixed	The values or expressions to operate on. String values will be treated as column names, except when they contain a parentheses `(`, in which case they will be treated as raw SQL expressions.

                public function __construct(mixed ...$operands)
{
    $this->operands = $operands;
}

add() public method

public Yiisoft\Db\Expression\Function\MultiOperandFunction add ( mixed $operand )
$operand	mixed

                public function add(mixed $operand): static
{
    $this->operands[] = $operand;
    return $this;
}

getOperands() public method

public array getOperands ( )
return	array	List of operands.

                public function getOperands(): array
{
    return $this->operands;
}
