how to save mysql query output to a file named (currentTime).csv - python-2.7

Question

i am trying to store the output of mysql query to a file. I need to have a file with extension .csv and its name should be the current time of my pc e.g: 2015-03-26 19:26:13.065000.csv.
when i execute this query
conn=mysql.connector.connect(user='root',password='',host='localhost',database='ER_PC_NK')
exe2 = conn.cursor()
exe2.execute("""SELECT tbl_site.Site_name, State_Code, Country_Code,Street_Address, instrum_start_date, instrum_end_date, Comment INTO OUTFILE 'myrecord.csv' FIELDS TERMINATED BY '|' OPTIONALLY ENCLOSED BY '"' ESCAPED BY '\\\\' LINES TERMINATED BY '\\n' FROM tbl_site JOIN tbl_site_monit_invent ON site_id = tbl_Site_site_id""")
first time it saved a file named myrecord.csv but second time NOT.After a long search on the internet i found that it cannot override the file myrecord.csv, so i decided to name the file as currentTime.csv, to do this i thought to try this kind of thing:
ss=DATE_FORMAT(NOW(),'_%Y_%m_%d_%H_%i_%s');
SET #t1=1
set #FOLDER = 'c:/tmp/';
SET #PREFIX = 'orders';
SET #EXT = '.csv';
SET #CMD = CONCAT("SELECT * FROM orders INTO OUTFILE '",#FOLDER,#PREFIX,#TS,#EXT,
"' FIELDS ENCLOSED BY '\"' TERMINATED BY ';' ESCAPED BY '\"'",
" LINES TERMINATED BY '\r\n';");
PREPARE statement FROM #CMD
but found an error: user defined variables are not defined, again googled and found user defined variables are available from Connector/NET version 5.2.2 while i'm using MySQL Connector Python v2.0.3 for python v2.7
i am very confused, if you have more better solution please tell. Your effort will be of great help. Thank you.

Answer 1

instead of user defined variables you can just do
import datetime
conn = mysql.connector.connect(user='root',password='',host='localhost',database='ER_PC_NK')
exe2 = conn.cursor()
exe2.execute(
"""SELECT tbl_site.Site_name, State_Code, Country_Code,
Street_Address, instrum_start_date, instrum_end_date,
Comment INTO OUTFILE %s FIELDS TERMINATED BY '|' OPTIONALLY
ENCLOSED BY '"' ESCAPED BY '\\\\' LINES TERMINATED BY '\\n'
FROM tbl_site JOIN tbl_site_monit_invent ON site_id = tbl_Site_site_id
""", (str(datetime.datetime.now()),))
