相同的查询和不同的结果SQL/PLUS PHP

我使用Oracle 11g和我不知道为什么我的查询返回不同的结果，当我使用SQL/PLUS，当我使用PHP相同的查询和不同的结果SQL/PLUS PHP

<?php 
$conn=oci_connect('system','3636','orcl'); 

$stid = oci_parse($conn, 
"SELECT num_chb 
FROM chambre 
WHERE num_chb NOT IN 
    (SELECT DISTINCT r.num_chb 
    FROM chambre c, 
      reservation r 
    WHERE (TO_DATE('2015-12-13','YYYY-MM-DD') NOT BETWEEN r.dat_arriv AND r.dat_depart) 
     AND (TO_DATE('2015-12-14','YYYY-MM-DD') NOT BETWEEN r.dat_arriv AND r.dat_depart)"); 


oci_execute($stid); 
$tab=array(); 

while ($row = oci_fetch_assoc($stid)) { 
    $tab[]=$row['NUM_CHB']; 
} 
print_r($tab); 
} 
?>

SQL Plus和PHP结果

您确定这两个示例（PHP和SqlPlus）都在同一个数据库上连接吗？ –

为什么你为Oracle/SQL * PLUS问题指定MySQL和sql-server标记？ –

您系统帐户的密码是'3636'？ –

我看到不同的查询：

PHP：

SELECT num_chb 
FROM chambre 
WHERE num_chb NOT IN 
    (SELECT DISTINCT r.num_chb 
    FROM chambre c, 
      reservation r 
    WHERE (TO_DATE('2015-12-13','YYYY-MM-DD') NOT BETWEEN r.dat_arriv AND r.dat_depart) 
     AND (TO_DATE('2015-12-14','YYYY-MM-DD') NOT BETWEEN r.dat_arriv AND r.dat_depart)

甲骨文：

SELECT num_chb 
FROM chambre 
WHERE num_chb NOT IN 
    (SELECT DISTINCT r.num_chb 
    FROM chambre c, 
      reservation r 
    WHERE (TO_DATE('2015-12-13','YYYY-MM-DD') NOT BETWEEN r.dat_arriv AND r.dat_depart) 
     AND (TO_DATE('2015-12-14','YYYY-MM-DD') NOT BETWEEN r.dat_arriv AND r.dat_depart) 
    AND (r.dat_arriv TO_DATE('2015-12-13','YYYY-MM-DD') NOT BETWEEN AND TO_DATE('2015-12-14','YYYY-MM-DD')) 
     AND (r.dat_depart NOT BETWEEN TO_DATE('2015-12-14','YYYY-MM-DD') TO_DATE('2015-12-14','YYYY-MM-DD'))

PD：我不能发表评论。

再次检查！
