python使用sqlite3 长语句插入出错
Python2.7
下面是源码，还有测试结果，原原本本在终端操作是没问题的，但是在python中跑就出bug了

import xlrd
import multiprocessing
from sql import sql_method
mysqlite=sql_method()
def table_compare():
query='''select * FROM compare_sales_order WHERE ( compare_sales_order.order_num, compare_sales_order.product_name, compare_sales_order.col_color) not IN(SELECT order_num, product_name, col_color FROM sales_order) '''
# print query
data=mysqlite.conn.execute(query)
for i in data:
    print i
table_compare()

原原本本的输入到终端没有任何问题
