俺有个6G的table(存成CSV文件大概有4G)放在SQL server上,试着用pyodbc把它读到
python里,用得就是简单的"select * from table",可是运行过程中内存消耗很快就过
了20G,这是咋会事啊?

所以中文叫闭壳龟。东亚和东南亚也有很多种。市面最常见的是黄缘闭壳龟。

http://en.wikipedia.org/wiki/Box_turtle
From wiki:
Turtles can defend themselves from predation by hiding, closing their shell
and biting. The risk of death is greatest in small animals due to their size
and weaker carapace and plastron. While the shell of an adult box turtle is
impenetrable to virtually any animal, they do not always close in a case of
threat. Common predators are mammals like minks, skunks, raccoons, dogs and
rodents, but also birds (e.g. crows, ravens) and snakes (e.g. racers,
cottonmouths) are known to kill box turtles.[

Mine looks like this one at http://srelherp.uga.edu/turtles/pics/tercar5.jpg
I missed it very much.
My friend and I went fishing at a mountain after a night of rain.
He found a turtle swimming in the lake and rescued it. It was very beautiful.
So I brought it home. But soon I found my state law doesn't allow me to pet
it
so I went to the mountain and released it immediatly.
