ImplementsYiisoft\Db\Expression\ExpressionInterface

Represents SQL expression that returns the longest string from a list of operands.

This function compares the lengths of the provided strings or expressions and returns the longest one. If multiple strings have the same maximum length, it returns the first one encountered.

Example usage:

$longest = new Longest(new Value('short'), 'column_name');

See also \Yiisoft\Db\Expression\Function\LongestBuilder for building SQL representations of this function expression.

__construct() public method

Defined in: Yiisoft\Db\Expression\Function\MultiOperandFunction::__construct()

public __construct( mixed $operands ): mixed
$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.
