PHP mysql多个选择查询不起作用

Question

My sql Query is not working. I need to filter a data with Location but it not works. Why this is not working

$sql = "SELECT count(*) FROM entries WHERE location 
IN ('chennai,Bangalore') AND en_id = 'test' AND date(datetime) 
BETWEEN '2015-10-02' AND '2015-10-31'";

Answer 1

You need to update your query

IN ('chennai,Bangalore')

into

IN ('chennai','Bangalore')

Answer 2

try this table and query and analyst it hope will help you table as follows

CREATE TABLE IF NOT EXISTS `entries` (
 `id` int(15) NOT NULL,
 `location` varchar(255) NOT NULL,
 `en_id` varchar(25) NOT NULL ,
 `date` datetime NOT NULL DEFAULT CURRENT_TIMESTAMP
 ) ENGINE=InnoDB AUTO_INCREMENT=10 DEFAULT CHARSET=latin1;

--
-- Dumping data for table `entries`
--

 INSERT INTO `entries` (`id`, `location`, `en_id`, `date`) VALUES
 (1, 'chennai', 'test', '2015-10-31 12:53:38'),
 (2, 'Bangalore', 'test', '2015-10-31 12:53:38'),
 (3, 'chennai', 'test', '2015-10-13 12:53:38'),
 (4, 'chennai', 'test', '2015-10-05 12:53:38'),
 (5, 'chennai', 'test1', '2015-10-03 00:00:00'),
 (6, 'Bangalore', 'test', '2015-10-04 12:53:38'),
 (7, 'Bangalore', 'test1', '2015-10-03 00:00:00'),
 (8, 'chennai', 'test1', '2015-10-30 00:00:00'),
 (9, 'Bangalore', 'test1', '2015-10-30 00:00:00');

This is the query to get your desired result

 SELECT count(*) FROM entries WHERE location 
 IN ('chennai','Bangalore') AND en_id = 'test1' AND date(NOW()) 
 BETWEEN '2015-10-02' AND '2015-10-31'
