php 's mysql_query function didn't support more LIKE statament?

I queried:

select * 
  from marrydays 
 where YMD_X like '2010-1-%' 
   and marrydays.CONG not like 'aa%' 
   and marrydays.CONG not like 'bb%' ;

But after I use mysql_fetch_object function,I didn't got exact result,the result just like I queried :

select * from marrydays where YMD_X like '2010-1-%' ;

Why?

Some code pieces:

$res1 = $db->find("select * from marrydays where YMD_X like"." '".$cnDate."%' and CONG not like '冲".$male_shu."%' ;");

public function find($sql, $key=null){ $data = array(); $result = $this->query(开发者_运维技巧$sql); while($row = mysql_fetch_object($result)){ if(!empty($key)){ $data[$row->{$key}] = $row; }else{ $data[] = $row; } } return $data; }

public function query($sql){
    $stime = microtime(true);

    $result = mysql_query($sql, $this->conn);
    $this->query_count ++;
    if($result === false){
        throw new Exception(mysql_error($this->conn)." in SQL: $sql");
    }

    $etime = microtime(true);
    $time = number_format(($etime - $stime) * 1000, 2);
    $this->query_list[] = $time . ' ' . $sql;
    return $result;
}

Since PHP's mysql_query function just passes things to MySQL as you wrote them, are you sure that running the same query directly on MySQL gives a different result?

The problem here almost certainly lies with your query.
