I am using Python to query a MySQL table and getting one datetime in string format, which is stored in row[3]. I need to convert this string timestamp to epoch seconds.
import MySQLdb
import os
import datetime
try:
db = MySQLdb.connect("localhost","root","","test" )
except MySQLdb.Error, e:
print "Error %d: %s" % (e.args[0], e.args[1])
sys.exit (1)
cursor = db.cursor()
cursor.execute ("SELECT * from main_tbl WHERE login_user_name='kumar'")
data = cursor.fetchall()
for row in data :
print row[3] ###printing 2014-09-26 12:24:23
date = datetime.datetime.strptime(row[3], "%Y-%m-%d %H:%M:%S")
print date
On execution it throws this error:
2014-09-26 12:24:23
Traceback (most recent call last):
File "test1.py", line 22, in <module>
date = datetime.datetime.strptime(row[3], "%Y-%m-%d %H:%M:%S")
TypeError: must be string, not datetime.datetime
What am I doing wrong?
I have also tried the following:
epoch_start = time.mktime(time.strptime(row[3], "%Y-%m-%d %H:%M:%S"));
But I get this error:
Traceback (most recent call last):
File "test1.py", line 29, in <module>
epoch_start = time.mktime(time.strptime(row[3], "%Y-%m-%d %H:%M:%S"));
File "C:\Python27\lib\_strptime.py", line 467, in _strptime_time
return _strptime(data_string, format)[0]
File "C:\Python27\lib\_strptime.py", line 322, in _strptime
found = format_regex.match(data_string)
TypeError: expected string or buffer
row[3] is already in datetime.datetime format.
From your question its sounds like you want convert to EPOCH so do something like:
import time
epochTime = time.mktime(row[3].timetuple())
print epochTime
Then check if the converted epoch is correct or not:
print time.strftime('%Y-%m-%d %H:%M:%S', time.localtime(epochTime))
print row[3]
Verify last two statements have the same output.
