Question

我在Phpmyadmin中运行查询并使用php PDO执行相同的查询，但结果不相同。可能有什么不对？这是查询：

SELECT dim_date_key as date ,dim_jdate_key as jdate, SUM(val_call_counts) as count
FROM `fact_j_service_location_table_ts` 
WHERE `dim_time_stamp` >= '1426451400'
AND `dim_time_stamp` < '1427311800' 
AND dim_service_id  = 2  
GROUP BY dim_date_key  
LIMIT 0,10;

phpmyadmin：

date        jdate       count   
20150316    13931225    5711    
20150317    13931226    6170    
20150318    13931227    7244    
20150319    13931228    7825    
20150320    13931229    6261    
20150321    13940101    4622    
20150322    13940102    4513    
20150323    13940103    4671

但是php返回：

20150316    13931225    6295    
20150317    13931226    6170    
20150318    13931227    7244    
20150319    13931228    14170   
20150320    13931229    6261    
20150321    13940101    4622    
20150322    13940102    16879   
20150323    13940103    4671

这里是php脚本：

$sql = "SELECT dim_date_key as date ,dim_jdate_key as jdate, SUM(val_call_counts) as count
    FROM `fact_j_service_location_table_ts` 
    WHERE `dim_time_stamp` >= '1426451400'
    AND `dim_time_stamp` < '1427311800' 
    AND dim_service_id  = 2  
    GROUP BY dim_date_key  
    LIMIT 0,10;";
$db = new PDO($server ,$username, $pass, $opt);
$this_result = $db->prepare($sql);
$this_result->execute();
//$error = $this_result->errorInfo();

$res = $this_result->fetchAll(PDO::FETCH_ASSOC);

我不确定但计数和日期是MySQL中保留的关键字，所以如果你试图逃避它们，它应该有效：

AS `date`
AS `count`

phpmyadmin和php PDO之间的区别
