Sqlite version for Python 3.x - python

I want to use sqlite3 with Python 3.1.3 and I need to set enable_load_extension to true. To do this I believe I need sqlite version 3.x. From reading posts here it looks like a suitable version of sqlite ought to be bundled with python version 2.6 and up. However, when I do:
import sqlite3
sqlite3.version_info
The result returned is: '2.4.1'
I get the same answer on a different machine running Python 2.6.
The pysqlite site has no binaries for Python 3.x. My copy of Python came from the official Python site.
So:
1) What version of sqlite should I have with 3.1?
2) If I ought to have a more up to date version where has it gone - do I need to set an environment variable?
2) If I need to u

Don't confuse the version of SQLite with the version of pysqlite, the Python binding for the SQLite API. The version and version_info attributes you used refer to the latter.
Ever wondered why the module is named sqlite3? It only supports version 3.x!
To check the SQLite version, use sqlite_version instead:
import sqlite3
print sqlite3.sqlite_version
On my Python 2.6 installation, this prints 3.5.9. For Python 3.2, I get 3.7.4.
You can also use SQL to get the version:
>>> import sqlite3
>>> connection = sqlite3.connect(':memory:')
>>> cursor = connection.cursor()
>>> cursor.execute('SELECT sqlite_version()').fetchone()
('3.7.4',)

You need sqlite3.sqlite_version_info ... this is 3.5.9 for Python 2.6 and 3.1, 3.6.21 for Python 2.7, and 3.7.4 for Python 3.2. What you have got is the version of pysqlite.
Have you tried to "set enable_load_extension to true"?
You may wish to read some of this long saga ...

How to connect python 3.11 with mysql? [duplicate]

I am using ActiveState Python 3 on Windows and wanted to connect to my MySQL database.
I heard that mysqldb was the module to use.
I can't find mysqldb for Python 3.
Is there a repository available where the binaries exist for mysqldb?
How can I connect to MySQL in Python 3 on Windows?
There are currently a few options for using Python 3 with mysql:
https://pypi.python.org/pypi/mysql-connector-python
Officially supported by Oracle
Pure python
A little slow
Not compatible with MySQLdb
https://pypi.python.org/pypi/pymysql
Pure python
Faster than mysql-connector
Almost completely compatible with MySQLdb, after calling pymysql.install_as_MySQLdb()
https://pypi.python.org/pypi/cymysql
fork of pymysql with optional C speedups
https://pypi.python.org/pypi/mysqlclient
Django's recommended library.
Friendly fork of the original MySQLdb, hopes to merge back some day
The fastest implementation, as it is C based.
The most compatible with MySQLdb, as it is a fork
Debian and Ubuntu use it to provide both python-mysqldb andpython3-mysqldb packages.
benchmarks here: https://github.com/methane/mysql-driver-benchmarks
You should probably use pymysql - Pure Python MySQL client instead.
It works with Python 3.x, and doesn't have any dependencies.
This pure Python MySQL client provides a DB-API to a MySQL database by talking directly to the server via the binary client/server protocol.
Example:
import pymysql
conn = pymysql.connect(host='127.0.0.1', unix_socket='/tmp/mysql.sock', user='root', passwd=None, db='mysql')
cur = conn.cursor()
cur.execute("SELECT Host,User FROM user")
for r in cur:
print(r)
cur.close()
conn.close()
if you want to use MySQLdb first you have to install pymysql on your pc by typing in cmd of windows
pip install pymysql
then in python shell, type
import pymysql
pymysql.install_as_MySQLdb()
import MySQLdb
db = MySQLdb.connect("localhost" , "root" , "password")
this will establish the connection.
I also tried using pymysql (on my Win7 x64 machine, Python 3.3), without too much luck. I downloaded the .tar.gz, extract, ran "setup.py install", and everything seemed fine. Until I tried connecting to a database, and got "KeyError [56]". An error which I was unable to find documented anywhere.
So I gave up on pymysql, and I settled on the Oracle MySQL connector.
It comes as a setup package, and works out of the box. And it also seems decently documented.
Summary
Mysqlclient is the best alternative(IMHO) because it works flawlessly with
Python 3+, follows expected conventions (unlike mysql
connector), uses the object name mysqldb which enables convenient porting of
existing software and is used by Django for Python 3 builds
Is there a repository available where the binaries exist for mysqldb?
Yes. mysqlclient allows you to use mysqldb functions. Though,
remember this is not a direct port by mysqldb, but a build by mysqlclient
How can I connect to MySQL in Python 3 on Windows?
pip install mysqlclient
Example
#!/Python36/python
#Please change above path to suit your platform. Am running it on Windows
import MySQLdb
db = MySQLdb.connect(user="my-username",passwd="my-password",host="localhost",db="my-databasename")
cursor = db.cursor()
cursor.execute("SELECT * from my-table-name")
data=cursor.fetchall()
for row in data :
print (row)
db.close()
I can't find mysqldb for Python 3.
mysqldb has not been ported yet
Untested, but there are some binaries available at:
Unofficial Windows Binaries
PyMySQL gives MySQLDb like interface as well. You could try in your initialization:
import pymysql
pymysql.install_as_MySQLdb()
Also there is a port of mysql-python on github for python3.
https://github.com/davispuh/MySQL-for-Python-3
Oracle/MySQL provides an official, pure Python DBAPI driver: http://dev.mysql.com/downloads/connector/python/
I have used it with Python 3.3 and found it to work great. Also works with SQLAlchemy.

On my mac os maverick i try this:
In Terminal type:
1)mkdir -p ~/bin ~/tmp ~/lib/python3.3 ~/src 2)export TMPDIR=~/tmp
3)wget -O ~/bin/2to3
4)http://hg.python.org/cpython/raw-file/60c831305e73/Tools/scripts/2to3

9)python3.3 setup.py install --install-lib=$HOME/lib/python3.3
--install-scripts=$HOME/bin
After that, enter in the python3 interpreter and type:
import pymysql.
If there is no error your installation is ok. For verification write a script to connect to mysql with this form:
# a simple script for MySQL connection
import pymysql db = pymysql.connect(host="localhost", user="root", passwd="*", db="biblioteca") #Sure, this is
information for my db # close the connection db.close ()*
Give it a name ("con.py" for example) and save it on desktop. In Terminal type "cd desktop" and then
$python con.py
If there is no error, you are connected with MySQL server. Good luck!
CyMySQL
https://github.com/nakagami/CyMySQL
I have installed pip on my windows 7, with python 3.3
just
pip install cymysql
(you don't need cython)
quick and painless
This does not fully answer my original question, but I think it is important to let everyone know what I did and why.
I chose to continue using python 2.7 instead of python 3 because of the prevalence of 2.7 examples and modules on the web in general.
I now use both mysqldb and mysql.connector to connect to MySQL in Python 2.7. Both are great and work well. I think mysql.connector is ultimately better long term however.
I'm using cymysql with python3 on a raspberry pi
I simply installed by:
sudo pip3 install cython
sudo pip3 install cymysql
where cython is not necessary but should make cymysql faster
So far it works like a charm and very similar to MySQLdb
This is a quick tutorial on how to get Python 3.7 working with Mysql
Thanks to all from who I got answers to my questions

Problem upgrading Sqlite3 version on CentOS for Python

I have CentOS 6 on my system and I'm trying to update SQLite for Python. I've installed it from source and executing sqlite --version returns version 3.33.0 as expected.
However, when I try to check the python SQLite version using import sqlite3; sqlite3.sqlite_version; I still get the previous SQLite version 3.6.20.
Software Locations:
Python 3.6.9 - /usr/bin/python3
Sqlite3 - /usr/bin/sqlite3
I've tried the solution here, this does not work at all, after updating LD_LIBRARY_PATH and checking the python SQLite version it still gives '3.6.20', and here, when I try sudo LD_RUN_PATH=, it gives me the error No such file or directory, but when I execute it without sudo LD_RUN_PATH=, it successfully compiles but still gives me SQLite '3.6.20' (Compiled python without uninstalling).
Note: I have multiple python3 versions.
What can I do to resolve this?
When I did it (specifically trying to find a way to update sqlite3 for a running python program; did not work...), I compiled sqlite and got libsqlite3.so.0.8.6, and then replaced the system-wide sqlite3 with that. For me on debian, that was in /usr/lib/x86_64-linux-gnu. I did see (though now I can't find where) that this way may cause issues when updating in the future. It did update python's sqlite3 for me though.
You can import specific versions:
__requires__= 'sqlite3==3.6.20'
import pkg_resources
pkg_resources.require("sqlite3==3.6.20")
import sqlite
Note that this only works on the first import. If sqlite gets imported before pkg_resources, it will take the latest version.

How to change SQLite version used by Python?

I have Python 3.8 installed alongside SQLite 3.16.2 on Debian 9.12 and I need to upgrade to a newer version of SQLite. I've downloaded and compiled the amalgamation available on the SQLite's site, and put it in /usr/bin, so when I do
$ sqlite3 --version
I get 3.32.3 in response (which is the version I compiled).
However, when I do
$ python3.8
>>> import sqlite3
>>> sqlite3.sqlite_version
I get 3.16.2, which is the earlier version. How do I change the SQLite version picked up by Python?
mkrieger1 suggested that this question may answer mine. It won't work here, as the solution provided there is directed at Python 2, not Python 3. pysqlite2 does not work with Python 3.
In my case I cannot replace with newer version because I cannot find these files. (I installed the sqlite-autoconf-3350500)
I used another manner to let it work just execute below command
export LD_LIBRARY_PATH="/usr/local/lib"
>>> import sqlite3
>>> sqlite3.sqlite_version
'3.35.5'
The way I would go around it, is by finding out the path to the old sqlite version that you are importing:
import sqlite3
print(sqlite3.__file__)
For me, this outputs:
C:\Users\YOUR_USERNAME_HERE\AppData\Local\Programs\Python\Python38\lib\sqlite3\__init__.py
Go to the lib path:
C:\Users\YOUR_USERNAME_HERE\AppData\Local\Programs\Python\Python38\lib
Then find the sqlite3 folder and delete it, then replace it with your up-to-date version. Re-try:
>>> import sqlite3
>>> sqlite3.sqlite_version
You should get your new version.

I now use both mysqldb and mysql.connector to connect to MySQL in Python 2.7. Both are great and work well. I think mysql.connector is ultimately better long term however.
I'm using cymysql with python3 on a raspberry pi
I simply installed by:
sudo pip3 install cython
sudo pip3 install cymysql
where cython is not necessary but should make cymysql faster
So far it works like a charm and very similar to MySQLdb
This is a quick tutorial on how to get Python 3.7 working with Mysql
Thanks to all from who I got answers to my questions
- hope this helps somebody someday.
----------------------------------------------------
My System:
Windows Version: Pro 64-bit
REQUIREMENTS.. download and install these first...
1. Download Xampp..
https://www.apachefriends.org/download.html
2. Download Python
https://www.python.org/downloads/windows/
--------------
//METHOD
--------------
Install xampp first after finished installing - install Python 3.7.
Once finished installing both - reboot your windows system.
Now start xampp and from the control panel - start the mysql server.
Confirm the versions by opening up CMD and in the terminal type
c:\>cd c:\xampp\mysql\bin
c:\xampp\mysql\bin>mysql -h localhost -v
Welcome to the MariaDB monitor. Commands end with ; or \g.
Your MariaDB connection id is 2
Server version: 10.1.21-MariaDB mariadb.org binary distribution
Copyright (c) 2000, 2016, Oracle, MariaDB Corporation Ab and others.
This is to check the MYSQL version
c:\xampp\mysql\bin>python
Python 3.7.0b3 (v3.7.0b3:4e7efa9c6f, Mar 29 2018, 18:42:04) [MSC v.1913 64 bit (AMD64)] on win32
This is to check the Python version
Now that both have been confirmed type the following into the CMD...
c:\xampp\mysql\bin>pip install pymysql
After the install of pymysql is completed.
create a new file called "testconn.py" on your desktop or whereever for quick access.
Open this file with sublime or another text editor and put this into it.
Remember to change the settings to reflect your database.
#!/usr/bin/python
import pymysql
pymysql.install_as_MySQLdb()
import MySQLdb
db = MySQLdb.connect(user="yourusernamehere",passwd="yourpasswordhere",host="yourhosthere",db="yourdatabasehere")
cursor = db.cursor()
cursor.execute("SELECT * from yourmysqltablehere")
data=cursor.fetchall()
for row in data :
print (row)
db.close()
Now in your CMD - type
c:\Desktop>testconn.py
And thats it... your now fully connected from a python script to mysql...
Enjoy...
imports
import pymysql
open database connection
db = pymysql.connect("localhost","root","","ornament")
prepare a cursor object using cursor() method
cursor = db.cursor()
sql = "SELECT * FROM item"
cursor.execute(sql)
Fetch all the rows in a list of lists.
results = cursor.fetchall()
for row in results:
item_title = row[1]
comment = row[2]
print ("Title of items are the following = %s,Comments are the following = %s" % \
(item_title, comment))
follow these steps:
import pymysql
install
python -m pip install PyMySQL
python -m pip install PyMySQL[rsa]
python -m pip install PyMySQL[ed25519]
finally try again to install pip install mysql-connector.
these steps solved my error
