1.查询指定字段，条件为某个字段多个值，并分组累计，结果排序：
#!/usr/bin/python
# encoding=utf-8
from flask.ext.sqlalchemy import SQLAlchemy
import sqlalchemy
#查询语句：
ips=["10.60.147.166",
"10.60.147.167",
"10.60.148.205",
"10.60.148.5",
"10.60.148.6",
"10.60.148.71",
"10.60.149.137",
"10.60.149.158",
"10.60.149.224",
"10.60.149.225",
"10.60.149.30",
"10.60.150.170",
"10.60.150.32",
"10.60.151.92"]
qres1=db.session.query(HourStatic.static_time,sqlalchemy.sql.func.sum(HourStatic.shownum),sqlalchemy.sql.func.sum(HourStatic.clicknum)).filter(HourStatic.ip.in_(ips),HourStatic.reason==args[1],HourStatic.static_time.between(args[2],args[3])).group_by(HourStatic.static_time).order_by(sqlalchemy.asc(HourStatic.static_time)).all()
qres2=db.session.query(HourWholeStatic.static_time,sqlalchemy.sql.func.sum(HourWholeStatic.shownum)).filter(HourWholeStatic.ip.in_(ips),HourWholeStatic.static_time.between(args[2],args[3])).group_by(HourWholeStatic.static_time).group_by(HourWholeStatic.static_time).order_by(sqlalchemy.asc(HourWholeStatic.static_time)).all()
#访问结果方法：
if (qres1 is not None) and (qres2 is not None):
tdict={}
for it in qres2:
tdict[it[0]]=it[1]
for it1 in qres1:
if tdict.has_key(it1[0]):
shows.append(long(it1[1]))
clicks.append(long(it1[2]))
ctr.append(float(it1[2])/float(it1[1]))
srate.append(float(it1[1])/float(tdict[it1[0]]))
times.append(it1[0].strftime(time_format[tp])) 2.执行mysql语句：
import sqlalchemy
engine = sqlalchemy.create_engine('mysql://root:[email protected]:3306/db_news_news_report?charset=utf8', echo=True)
DB_Session =sqlalchemy.orm.sessionmaker(bind=engine)
conn = DB_Session()
items=conn.execute("select DATE_FORMAT(static_date,'%%Y%%u') week,sum(shownum) as shownum,sum(clicknum) as clicknum from tb_day_whole_static where static_date>='%s' and static_date<='%s' group by week;"%(args[0],args[1])).fetchall()
if items is not None:
for it1 in items:
shows.append(long(it1[1]))
clicks.append(long(it1[2]))
ctr.append(float(it1[2])/float(it1[1]))
if tp in time_format.keys():
times.append(it1[0].strftime(time_format[tp]))
else:
times.append(it1[0])
if isinstance(items, sqlalchemy.engine.result.ResultProxy):
items.close()
