php获得sybase数据库内容的问题
数据库连接已经测试过了没问题，sql语句也没问题。现在问题是获取不到数据库里的数据，代码如下：
public static function Connect()<br /> {<br /> $obj =new DB();<br /> $conn=$obj->Connection=sybase_connect(SERVER_NAME, USER, PASSWORD) ; // 连接数据库<br /> if(!$conn){<br /> echo '数据库连接错误...';<br /> exit(0);<br /> }<br /> sybase_select_db(DATABASE_NAME);<br /> return $obj; <br /> }<br /> //初始化页面时查询最近一个月的销售记录<br /> public function QueryLastMonth(){<br /> $start_date=str_replace('-','',date('Y-m-d',strtotime('-1 month')));<br /> $end_date=str_replace('-','',date('Y-m-d',time()));<br /> $sql_str="select cusno as shopcode,u2.nos as salesid,u2.colthno as goodsid,u2.endprice as price,u2.nb as goodscount from u2sale u1,u2saleb u2 where u1.outdate>=";<br />$sql=$sql_str ."'".$start_date."' and u1.outdate<='".$end_date."' and u1.nos=u2.nos and u1.nb>0 and u2.endprice>0;";<br /><br /> //echo $sql;<br /> // sybase_query("set rowcount " . 20) ; // 执行SQL命令，设置返回记录行数<br /> $result = sybase_query($sql) ; // 执行SQL命令，检索数据库<br /> echo "---".$result;<br /> while($row = sybase_fetch_assoc($result)) <br /> { <br /> // echo 'xxx';<br /> echo $row["shopcode"] . "---" . $row["salesid"] . "---" . $row["goodscount"] . "\n" ;<br /> }<br /> <br /> sybase_close($conn);<br /> }
