Yii addInCondition with floats: How to ?为什么 addInCondition('column', array(1.1, 1.3)) 不起作用?

问题描述

如何使用浮点数添加InCondition?

How to addInCondition with floats?

我尝试了很多.

这没问题:

$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:

In my case it returns 4 models:

但是如果我尝试

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

或

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

或

$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 t WHERE step=:ycp1. Bound with :ycp1=3.2)

phpmyadmin 中的这个查询返回 5360 行

This query in phpmyadmin returns 5360 rows

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

phpmyadmin 中的这个查询返回 0 行

This queries in phpmyadmin returns 0 rows

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

returns Models with step=3 OR 20

phpmyadmin 中的此查询返回 step=3 OR 20 的行

This query in phpmyadmin returns rows with step=3 OR 20

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

那么，如何使用浮点数addInCondition?

So, how to addInCondition with floats?

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 ;

Yii 版本:1.1.10

Yii version: 1.1.10

推荐答案

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

在 Yii 日志中查询

Query in Yii logs

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

Real query in MySql logs

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
