如何用浮点数添加InCondition?

我尝试了很多。

这工作正常:

$criteria=new CDbCriteria();
$criteria->addInCondition('order_id',array(36907));
$tasks=OrderTask::model()->findAll($criteria);

就我而言,它返回 4 个模型:

但如果我尝试

$criteria=new CDbCriteria();
$criteria->addInCondition('order_id',array(36907));
$criteria->addInCondition('step',array(3.20));
$tasks=OrderTask::model()->findAll($criteria);

或者

$criteria=new CDbCriteria();
$criteria->addInCondition('step',array("3.20"));
$tasks=OrderTask::model()->findAll($criteria);

或者

$criteria=new CDbCriteria();
$criteria->addInCondition('step',array('3.2'));
$tasks=OrderTask::model()->findAll($criteria);

结果为空。

根据日志,查询为:

system.db.CDbCommand.query(SELECT * FROM orders_tasks tWHERE step=:ycp1. 绑定:ycp1=3.2)

phpmyadmin 中的此查询返回 5360 行

SELECT * FROM  `orders_tasks`  `t` WHERE step = 3.20

phpmyadmin 中的此查询返回 0 行

SELECT * FROM  `orders_tasks`  `t` WHERE step = '3.20'
SELECT * FROM  `orders_tasks`  `t` WHERE step = '3.2'
SELECT * FROM  `orders_tasks`  `t` WHERE step = "3.20"

这次尝试

$criteria=new CDbCriteria();
$criteria->addInCondition('step',array("3,20"));
$tasks=OrderTask::model()->findAll($criteria);

返回 step=3 OR 20 的模型

phpmyadmin 中的此查询返回 step=3 OR 20 的行

SELECT * FROM  `orders_tasks`  `t` WHERE step = '3,20'

那么,如何addInCondition使用花车呢?

细节,例如

step字段是float(8,2)

Sql 表转储:

CREATE TABLE IF NOT EXISTS `orders_tasks` (
  `task_id` int(11) NOT NULL AUTO_INCREMENT,
  `order_id` int(11) NOT NULL,
  `step` float(6,2) NOT NULL,
  `done` int(1) NOT NULL DEFAULT '0',
  PRIMARY KEY (`task_id`),
  KEY `order_id` (`order_id`),
  KEY `step` (`step`),
  KEY `orderstep` (`order_id`,`step`)
) ENGINE=InnoDB  DEFAULT CHARSET=utf8 AUTO_INCREMENT=4 ;

DROP TABLE IF EXISTS `prefix_test`;

CREATE TABLE IF NOT EXISTS `prefix_test` (
  `task_id` int(11) NOT NULL AUTO_INCREMENT,
  `order_id` int(11) NOT NULL,
  `step` float(6,2) NOT NULL,
  `done` int(1) NOT NULL DEFAULT '0',
  PRIMARY KEY (`task_id`),
  KEY `order_id` (`order_id`),
  KEY `step` (`step`),
  KEY `orderstep` (`order_id`,`step`)
) ENGINE=InnoDB  DEFAULT CHARSET=utf8 AUTO_INCREMENT=4 ;


INSERT INTO `prefix_test` VALUES (1,36907,3.20,0);
INSERT INTO `prefix_test` VALUES (2,36907,3.21,0);
INSERT INTO `prefix_test` VALUES (3,37907,4.13,0);

$criteria=new CDbCriteria();
$criteria->addInCondition('order_id',array(36907));
$criteria->addInCondition('step',array(3.20));
$tests=Test::model()->findAll($criteria);


echo "Rows: ".count($tests)."<br>";
#Returns Rows: 0

Yii 日志中的查询

SELECT * FROM `prefix_test` `t` WHERE (order_id=:ycp0) AND (step=:ycp1). Bound with :ycp0=36907, :ycp1=3.2

MySql 日志中的真实查询

SELECT * FROM `prefix_test` `t` WHERE (order_id=36907) AND (step='3.2')

这将解决您的问题

ALTER TABLE `prefix_test` CHANGE `step` `step` decimal(10,2) NOT NULL;

之后您的查询返回

#Returns Rows: 1
