python manage.py migrate returns with django.db.utils.ProgrammingError: (1064... error

Question

I am a newbie and I am trying to create a django project on Windows 8 with Python 3 and Django 1.8.6 using mysql database

When I execute python manage.py migrate I get an error as

django.db.utils.ProgrammingError: (1064 ....

I have cross checked my settings.py file and everything. In fact the connection is established and sometimes it successfully creates tables django_content_type and django_migrations and then gives this error and sometimes without creating these tables itself I get this error.

The stack trace printed ends as follows :

django.db.utils.ProgrammingError: (1064, "You have an error in your SQL syntax; check the manual that corresponds to your MySQL server version for the right syntax to use near '%s' at line 1")

I have also referred and tried to follow the instructions (installed mysql-connector-python-2.1.3) in other similar queries at this site, but nothing seems to be working

The complete stack trace is as follows :

D:\pythonLearn\learningDjango\mysite>python manage.py migrate

Answer 1

django.db.utils.ProgrammingError: (1064, "You have an error in your SQL syntax; check the manual that corresponds to your MySQL server version for the right syntax to use near '(6) NOT NULL)' at line 1")

Need to upgrade mysql to 5.6 or later. This is caused because of DATETIME(6). which is supported 5.6 or lated version.

Reference https://docs.djangoproject.com/en/2.1/ref/databases/#fractional-seconds-support-for-time-and-datetime-fields

Answer 2

Your error message says ...

...for the right syntax to use near '%s' at line 1

This means the query your program passed to MySQL contained the text string %s . It looks to me like your program has not substituted a value into that string. It must do so before trying to use the string as a query.

This business of using placeholders in queries is commonplace. Is it possible your query says something like this?

 INSERT INTO names (name) VALUES (%s)

It needs to say this instead

 INSERT INTO names (name) VALUES ('Ban Ki Moon')

Answer 3

As @krishna chandak said, you should upgrade the MySQL version because of DATETIME(6) .

How to update MySQL version:

Make sure yum is up-to-date

yum update yum

Install yum-utils (it provides yum-config-manager)

yum install yum-utils

Backup: dump all databases to all_dbs.sql

mysqldump --lock-all-tables --all-databases -uroot -yourpassword >/root/all_dbs.sql

Stop MySQL daemon

service mysqld stop

Download latest MySQL

------ for CentOS 6

wget https://dev.mysql.com/get/mysql80-community-release-el6-2.noarch.rpm
sudo rpm -Uvh mysql80-community-release-el6-2.noarch.rpm

------ for CentOS 7

wget https://dev.mysql.com/get/mysql80-community-release-el7-3.noarch.rpm
sudo rpm -Uvh mysql80-community-release-el7-3.noarch.rpm

Remove old version and install 5.7 version

sudo yum-config-manager --enable mysql57-community
sudo yum-config-manager --disable mysql80-community
yum remove mysql55-server
yum install mysql57-server
yum update mysql

Start MySQL

service mysqld start

If you get any errors you have to remove deprecated variables in etc/my.cnf

Upgrade existing databases

mysql_upgrade -uroot -p

IF YOU HAME ERROR WITH *.sock

Change config /etc/my.cnf by adding

datadir=/var/lib/mysql

and commenting this string

# socket=/var/lib/mysql/mysql.sock

Then do steps to updating database and return config to previous state.
