Python uses sqlite3 long statement insertion error
Python2.7
The following is the source code, as well as the test results. It is no problem to operate in the terminal, but there is a bug when running in python

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()
