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

Represents a SQL GREATEST() function that returns the greatest value from a list of values or expressions.

Example usage:

$greatest = new Greatest(1, '(a + b)', $db->select('column')->from('table')->where(['id' => 1]));

GREATEST(1, (a + b), (SELECT "column" FROM "table" WHERE "id" = 1))

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