Update Values in Mysql - python

from dataa import *
dataman = mysql.connector.connect(host='localhost', user='root', passwd='12345678', database='basictest')
databoy = dataman.cursor()
with open('data.txt') as g:
data = g.read().split('\n')
vl = ['']
vm = ['SELECT Name FROM Patient', 'SELECT DOB FROM Patient', 'SELECT Email FROM Patient',
'SELECT Username FROM Patient', 'SELECT Password FROM Patient', 'SELECT Mobile FROM Patient']
x = 0
for j, i in zip(data, vm):
if
vl[0] = j
x += 1
databax = ("INSERT INTO Patient(Name) VALUES(%s)")
d = [('a')]
databoy.execute(databax, d)
dataman.commit()
print(x)
I want to append each value of J to each column seperately. Only thing I can do is that append all of that to same column . on addition of other column, it throws an error. What can I do. No use of classes will be apppreciated. Can I select each column seperately and update it each time I update the form. This is the registration form of a application

How to use multiple variables in pymysql

How can I use multiple variables in my query:
import pymysql
def get_firstname(y):
db = pymysql.connect(host="xxx.xxx.xxx.xxx",
user="xxxx",
passwd="xxxxx",
db="XXXXXXX")
cur = db.cursor()
query = "SELECT first_name FROM information WHERE x = y;"
cur.execute(query, (y))
result = str(cur.fetchone()[0])
return(result)
x = user_id
y = 1
print (get_firstname(y))
I would like to be able to change x to different variables, depending on my choice. Like user_id, last name, email etc. All columns in my database. #y is another variable which represent the value of the column in my database.
Ex1: if x is "user_id" and y is "1", then the result is the first name of the person with user_id 1.
Ex2: if x is "email" and y is "person#person.com", then the result is the first name of the person with the email person#person.com.

Use the below code:
import pymysql
def get_firstname(x, y):
db = pymysql.connect(host='xxx.xxx.xxx.xxx',
port=3306,
user='xxxx',
password='xxxxxxxx',
db='test_db')
cur = db.cursor()
query = "SELECT first_name FROM `information` WHERE %s" %(x)
final_query = query+"=%s"
#print(final_query)
cur.execute(final_query, (y,))
result = cur.fetchall()
return(result)
x = 'user_id'
y = 1
output = get_firstname(x,y)
if output:
for x in output:
print(x)[0]
Sample Inputs:
x = 'email_id'
y = 'xx#gmail.com'
or
x = 'user_id'
y = 1 // Not enclosed with single quotes

Working with dictionaries and data to and from database - Python 3

I have a data which looks like (as example) -
{"phone_number": "XXX1","phone_number_country": "XXX2","text": "XXX2"}
where XXX is my data (it can be different types of data)
Also, I have DB with data, which looks like (as example) -
[
Data is taken from DB:
con = sqlite3.connect('dab')
cur = con.cursor()
c = cur.execute('SELECT * FROM some')
u_data = c.fetchall()
Each row is a set of data.
The data is taken from the first row and data from column_1 goes to the place of XXX1, data from column_2 goes to the place of XXX2 and data from column_3 goes to the place of XXX3...
After that I should get the data from the original array (template) + data taken from the database...then this dict should be committed to DB and the loop should go on until the data from the DB and every time commit my new dict to DB...
Now I have some code:
import sqlite3
from itertools import product
a = {"phone_number": "XXX","phone_number_country": "XXX","text": "XXX"}
con = sqlite3.connect('dab')
cur = con.cursor()
c = cur.execute('SELECT * FROM some')
u_data = c.fetchall()
s = list(u_data)
b = list(zip(*u_data))
out = product(*b)
tout =list(out)
i = 0
for elem in b:
b[i] = elem
a["phone_number"] = elem[0]
a["phone_number_country"] = elem[1]
a["text"] = elem[2]
print(a)
and in console i have this:
{'text': 'phone_number31', 'phone_number_country': 'phone_number21', 'phone_number': 'phone_number11'}
{'text': 'phone_number_c32', 'phone_number_country': 'phone_number_c22', 'phone_number': 'phone_number_c12'}
{'text': 'text33', 'phone_number_country': 'text23', 'phone_number': 'text13'}
It should be:
{"phone_number": "phone_number11","phone_number_country": "phone_number_c12","text": "text13"}
{"phone_number": "phone_number21","phone_number_country": "phone_number_c22","text": "text23"}
{"phone_number": "phone_number31","phone_number_country": "phone_number_c32","text": "text33"}

Dictionaries in python do not maintain the insertion order by default. You need ordered dictionary for this.
I have reproduced a part of your code below:
import collections
a = collections.OrderedDict()
for elem in b:
b[i] = elem
a["phone_number"] = elem[0]
a["phone_number_country"] = elem[1]
a["text"] = elem[2]
print(a)

Answer here:
a = {"phone_number": "XXX","phone_number_country": "XXX","text": "XXX"}
con = sqlite3.connect('dab')
cur = con.cursor()
c = cur.execute('SELECT * FROM some')
u_data = c.fetchall()
s = list(u_data)
i = 0
for elem in s:
s[i] = elem
a["phone_number"] = elem[0]
a["phone_number_country"] = elem[1]
a["text"] = elem[2]

Python does not commit on insert query

I am trying to bulk insert locations on wordpress. I have defined functions to check and adding terms and taxonomy
def checkTerm(term,con):
cur = con.cursor()
query = "SELECT term_id FROM wp_terms as t WHERE t.name = '%s'" % term
print query
cur.execute(query)
rows = cur.fetchall()
if rows: return rows[0][0]
else : return None
def addTerm(term,slug,con):
cur = con.cursor()
try:
query = "INSERT INTO `wp_terms` (`name`,`slug`,`term_group`) VALUES ('%s','%s',0)" % (term,slug)
print query
cur.execute(query)
con.commit()
rows = checkTerm(term,con)
if rows: return rows[0][0]
else : return None
except:
return None
def checkTaxonomy(term_id,con):
cur = con.cursor()
query = "SELECT tt.term_taxonomy_id,tt.parent FROM wp_term_taxonomy AS tt INNER JOIN wp_terms AS t ON tt.term_id = t.term_id WHERE tt.taxonomy = 'project_location' AND t.term_id = '%s'" % term_id
print query
cur.execute(query)
rows = cur.fetchall()
if rows: return rows
else : return None
def addTaxonomy(term_id,taxonomy,description,parent,count,con):
cur = con.cursor()
query = "INSERT INTO `wp_term_taxonomy` (`term_id`,`taxonomy`,`description`,`parent`,`count`) VALUES ('%s','%s','%s','%s','%s')" % (term_id,taxonomy,description,parent,count)
print query
cur.execute(query)
con.commit()
rows = checkTaxonomy(term_id,con)
if rows: return rows
else: return None
I store cities in dictionary of dicionaries
df = pd.read_table('./Argentina.csv',sep='\t',header=None,engine='python')
for line in xrange(len(df)):
stringa = str(df[17][line])
location = str(df[1][line])
population = int(df[14][line])
if population < limit_pop: continue
string_state = stringa.split("/")
country = string_state[1]
state = string_state[2]
if not country in states:
states[country] = {}
if not state in states[country]:
states[country][state] = [location]
else :
states[country][state].append(location)
Then I try to insert terms and taxonomies in the wordpress db
con = mdb.connect('localhost', 'root', 'mypassword, 'Wordpress')
for country in states:
country_id = checkTerm(country.replace("_"," "),con)
if not country_id:
country_id = addTerm(country.replace("_"," "),country,con)
taxonomy = checkTaxonomy(country_id,con)
if not taxonomy:
taxonomy = addTaxonomy(country_id,'project_location','','0','0',con)
parent = dict((y, x) for x, y in taxonomy)
if not 0 in parent:
taxonomy = addTaxonomy(country_id,'project_location','','0','0',con)
for state in states[country]:
state_id = checkTerm(state.replace("_"," "),con)
if not state_id:
state_id = addTerm(state.replace("_"," "),state,con)
taxonomy = checkTaxonomy(state_id,con)
if not taxonomy:
taxonomy = addTaxonomy(state_id,'project_location','',country_id,'0',con)
parent = dict((y, x) for x, y in taxonomy)
if not country_id in parent:
taxonomy = addTaxonomy(state_id,'project_location','',country_id,'0',con)
for location in states[country][state]:
location_id=checkTerm(location.replace("_"," "),con)
if not location_id:
location_id = addTerm(location.replace("_"," "),location,con)
taxonomy = checkTaxonomy(location_id,con)
if not taxonomy:
taxonomy = addTaxonomy(location_id,'project_location','',state_id,'0',con)
parent = dict((y, x) for x, y in taxonomy)
if not state_id in parent:
taxonomy = addTaxonomy(location_id,'project_location','',state_id,'0',con)
When I try to execute the script I found this behaviour
SELECT term_id FROM wp_terms as t WHERE t.name = 'Argentina'
INSERT INTO `wp_terms` (`name`,`slug`,`term_group`) VALUES ('Argentina','Argentina',0)
SELECT term_id FROM wp_terms as t WHERE t.name = 'Argentina'
SELECT tt.term_taxonomy_id,tt.parent FROM wp_term_taxonomy AS tt INNER JOIN wp_terms AS t ON tt.term_id = t.term_id WHERE tt.taxonomy = 'project_location' AND t.term_id = 'None'
INSERT INTO `wp_term_taxonomy` (`term_id`,`taxonomy`,`description`,`parent`,`count`) VALUES ('None','project_location','','0','0')
SELECT tt.term_taxonomy_id,tt.parent FROM wp_term_taxonomy AS tt INNER JOIN wp_terms AS t ON tt.term_id = t.term_id WHERE tt.taxonomy = 'project_location' AND t.term_id = 'None'
And the script stop with the following error
./import.py:59: Warning: Truncated incorrect DOUBLE value: 'None'
cur.execute(query)
./import.py:69: Warning: Incorrect integer value: 'None' for column 'term_id' at row 1
cur.execute(query)
Traceback (most recent call last):
File "./import.py", line 115, in <module>
parent = dict((y, x) for x, y in taxonomy)
TypeError: 'NoneType' object is not iterable
This means that the insert statements are not executed. I don't understand. I con.commit() the query but it is still not executed. Where is the problem?

Solution:
I changed
import MySQLdb as mdb
to
import mysql.connector
and
con = mdb.connect(host='localhost',user='root', password='passowrd',database= 'Wordpress');
to
con = mysql.connector.connect(host='localhost',user='root', password='password',database= 'Wordpress',autocommit=False,buffered=False);

UnboundLocalError: local variable 'Core_prices' referenced before assignment

i use a function calculate servers prices so i made a function which retrieve a defalut prices of a server components and calculate server price for each server exsit in my DB but i try to run this function, i get this error:
function.py
import MySQLdb
def calculations_metric (param) :
db = MySQLdb.connect("localhost", "root", "aqw", "PFE_Project")
cursor = db.cursor()
sql = "SELECT * FROM examples_calculationsmetric"
cursor.execute(sql)
results = cursor.fetchall()
for row in results:
RAM_prices = int(row[1])
Core_prices = int(row[2])
HHD_SATA_prices =int(row[3])
HHD_SSD_prices =int(row[4])
CPU_priority = int(row[5])
Avaibility = int(row[6])
db.close()
db1 = MySQLdb.connect("localhost", "root", "aqw", "PFE_Project")
cursor1 = db1.cursor()
sql1 = "SELECT * FROM examples_servercomponents WHERE id ='%d'" %(param)
cursor1.execute(sql1)
results1 = cursor1.fetchall()
for row in results1:
if row[6] == 'SATA':
Core_price = int(row[2]) * Core_prices # the error is here
Priority_price = int(row[3]) * CPU_priority
RAM_price = int(row[4]) * RAM_prices
HDD_price = int(row[5]) * HHD_SATA_prices
Availibility_price = int(row[7])*Avaibility
elif row[6] == 'SSD':
Core_price = int(row[2]) * Core_prices
Priority_price = int(row[3]) * CPU_priority
RAM_price = int(row[4]) * RAM_prices
HDD_price = int(row[5]) * HHD_SSD_prices
Availibility_price = int(row[7])*Avaibility
price = Core_price + Priority_price + RAM_price + HDD_price + Availibility_price
db1.close()
return price
i don't get what is the error so if can anyone help i will be so greatful

When your SELECT * FROM examples_calculationsmetric doesn't return any results, Core_prices is never set (nor are the other variables in that loop).
Python names do not exist until assigned to, so if results is an empty list, the names inside the for loop never get assigned to and thus do not exist by the time you loop over results1 later on.
You could set default values for those names as a work-around:
RAM_prices = 0
Core_prices = 0
HHD_SATA_prices = 0
HHD_SSD_prices = 0
CPU_priority = 0
Avaibility = 0
to at least ensure that they are defined.
