是否可以在一个进程中访问数据库,在另一个进程中创建？我试过了:

空闲#1

import sqlite3
conn = sqlite3.connect(':memory:')
c = conn.cursor()
c.execute("create table test(testcolumn)")
c.execute("insert into test values('helloooo')")
conn.commit()
conn.close()

IDLE#2

import sqlite3
conn = sqlite3.connect(':memory:')
c = conn.cursor()
c.execute("select * from test")

错误:

Traceback (most recent call last):
  File "<pyshell#5>", line 1, in <module>
    q = c.execute("select * from test")
sqlite3.OperationalError: no such table: test
