區間查詢 默認使用AND 在最後面元素加上OR  SELECT * FROM `weibo_user` WHERE ( `id` > 1 OR `id` < 3 )
 $map[‘id‘]=array(
   array(‘gt‘,1),
   array(‘lt‘,3),
     ‘OR‘
 );
 組合查詢  SELECT * FROM `weibo_user` WHERE `id` = 1 OR ( username = "bnbbs" AND email like "%bnbb%" )
 $map[‘id‘]=array(‘eq‘,1);
 $map[‘_string‘]=‘username = "bnbbs" AND email like "%bnbb%"‘
 
;
 $map[‘_logic‘]="OR";
 請求字符串查詢
 $map[‘id‘]=array(‘eq‘,1);
 $map[‘_query‘]=‘username=bnbbs&_logic=OR‘;
 $map[‘_logic‘]=‘OR‘;
 復合查詢  SELECT * FROM `weibo_user` WHERE `id` = 1 OR ( `id` = 2 )
 $map[‘id‘]=array(‘eq‘,1);
 $where[‘id‘]=array(‘eq‘,2);
 $map[‘_complex‘]=$where;
 $map[‘_logic‘]=‘OR‘;
 統計查詢 count() 
 
SELECT COUNT(*) AS tp_count FROM `weibo_user` LIMIT 1
 最大查詢 max(id) SELECT MAX(id) AS tp_max FROM `weibo_user` LIMIT 1
 最小查詢 min(id) SELECT MIN(id) AS tp_min FROM `weibo_user` LIMIT 1
 平均值查詢 avg(id)  SELECT AVG(id) AS tp_avg FROM `weibo_user` LIMIT 1
 求和查詢 sum(id) SELECT SUM(id) AS tp_sum FROM `weibo_user`
 
 LIMIT 1
 動態查詢
 getByField(value) SELECT * FROM `weibo_user` WHERE `id` = 1 LIMIT 1
getByField(value) SELECT * FROM `weibo_user` WHERE `username` = ‘bnbbs‘ LIMIT 1
 getFieldByField(value) SELECT `id` FROM `weibo_user` WHERE `username` = ‘bnbbs‘ LIMIT 1
 SQL查詢 query($sql)只讀 execute($sql)只寫

 var_dump($user->query(‘select * from weibo_user‘));
