我必须显示其创建日期的数据库列表记录吗？

Question

template1=# SELECT (pg_stat_file('base/'||oid ||'/PG_VERSION')).modification, datname FROM pg_database;

 modification  |   datname

（24行）

在这上面列表中的第3条是跳过并且仅仅记录显示
之前，从当前日起15日内

，我怎么办？

因此，只有19行显示在输出中。

我想在eclipse中的控制台上打印答案。

Answer 1

SELECT * 
    FROM (SELECT 
      (pg_stat_file('base/'||oid ||'/PG_VERSION')).modification, 
      datname 
     FROM pg_database 
     ) dbs 
WHERE datname NOT IN ('template1', 'template0', 'postgres') 
    AND age(modification) > INTERVAL '15 days'; 

Answer 2

在.py文件

@api.multi 
def get_database_list(self): 
    self._cr.execute("SELECT (pg_stat_file('base/'||oid ||'/PG_VERSION')).modification, datname FROM pg_database") 
    temp = [] 
    res=self._cr.fetchall() 
    dt=datetime.utcnow() - timedelta(15) 
    for i in res: 
     dt1 = i[0].replace(tzinfo=None) 
     if(dt1 < dt): 
      result=self.env['ir.config_parameter'].search([('key','=','database.to.skip')]) 
      test=result.value.split(',') 
      if i[1] not in test: 
       temp.append((i[1])) 
    print temp 

在.xml文件

<record id="default_database_management" model="ir.config_parameter"> 
     <field name="key">database.to.skip</field> 
     <field name="value">template1,template0,postgres</field> 
    </record>
