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()
