类 yii\db\conditions\BetweenColumnsCondition
继承 | yii\db\conditions\BetweenColumnsCondition |
---|---|
实现 | yii\db\conditions\ConditionInterface |
自版本可用 | 2.0.14 |
源代码 | https://github.com/yiisoft/yii2/blob/master/framework/db/conditions/BetweenColumnsCondition.php |
类 BetweenColumnCondition 表示一个 BETWEEN
条件,其中值介于两个列之间。例如
new BetweenColumnsCondition(42, 'BETWEEN', 'min_value', 'max_value')
// Will be build to:
// 42 BETWEEN min_value AND max_value
更复杂的示例
new BetweenColumnsCondition(
new Expression('NOW()'),
'NOT BETWEEN',
(new Query)->select('time')->from('log')->orderBy('id ASC')->limit(1),
'update_time'
);
// Will be built to:
// NOW() NOT BETWEEN (SELECT time FROM log ORDER BY id ASC LIMIT 1) AND update_time
公共方法
方法详情
使用 BETWEEN
运算符创建条件。
public void __construct ( $value, $operator, $intervalStartColumn, $intervalEndColumn ) | ||
$value | ||
$operator | string |
要使用的运算符(例如 |
$intervalStartColumn | string|yii\db\ExpressionInterface |
作为间隔开头的列名或表达式 |
$intervalEndColumn | string|yii\db\ExpressionInterface |
作为间隔结束的列名或表达式 |
public function __construct($value, $operator, $intervalStartColumn, $intervalEndColumn)
{
$this->value = $value;
$this->operator = $operator;
$this->intervalStartColumn = $intervalStartColumn;
$this->intervalEndColumn = $intervalEndColumn;
}
使用数组定义创建对象,如 查询构建器 - 运算符格式 指南文章中所述。
public static $this fromArrayDefinition ( $operator, $operands ) | ||
$operator | string |
大写运算符。 |
$operands | array |
对应操作数的数组 |
抛出 | yii\base\InvalidArgumentException |
如果提供了错误数量的操作数。 |

public static function fromArrayDefinition($operator, $operands)
{
if (!isset($operands[0], $operands[1], $operands[2])) {
throw new InvalidArgumentException("Operator '$operator' requires three operands.");
}
return new static($operands[0], $operator, $operands[1], $operands[2]);
}
