SQL query with parameters

I use SQLite to merge two dataframes I have parameters in. Some work, others don't.
This works:
s = path_autre_qdv+'\\' + fichier_in
DATA = p.read_csv(s)
con = sql.connect('test_db.sqlite')
con.create_function('POWER', 2, sqlite_power)
c = con.cursor()
COM_DETAIL.to_sql('COM_DETAIL_SQL', con, if_exists='replace', index = False)
DATA.to_sql('DATA_SQL', con, if_exists='replace', index = False)
sq = """
SELECT
c.COM_CODE
,c.COM_NAME
,c.COM_LONG
,c.COM_LAT
,d.*
FROM
COM_DETAIL_SQL c
INNER JOIN
DATA_SQL d
ON POWER((c.COM_LONG - d.longitude)/ ? ,2) + POWER((c.COM_LAT - d.latitude)/ ? ,2) <= 1;
"""
par = (0.5, 0.5,)
RES = read_query(con,sq,par)
This doesn't:
s = path_autre_qdv+'\\' + fichier_in
DATA = p.read_csv(s)
con = sql.connect('test_db.sqlite')
con.create_function('POWER', 2, sqlite_power)
c = con.cursor()
COM_DETAIL.to_sql('COM_DETAIL_SQL', con, if_exists='replace', index = False)
DATA.to_sql('DATA_SQL', con, if_exists='replace', index = False)
sq = """
SELECT
c.COM_CODE
,c.COM_NAME
,c.COM_LONG
,c.COM_LAT
,d.*
FROM
COM_DETAIL_SQL c
INNER JOIN
DATA_SQL d
ON POWER((c.COM_LONG - d.longitude)/ ? ,2) + POWER((c.COM_LAT - d.latitude)/ ? ,2) <= 1
AND d.? IS NOT NULL AND d.? IS NOT NULL AND d.? IS NOT NULL;
"""
par = (0.5, 0.5,cinqv,meanv,nonentecinqv,)
RES = read_query(con,sq,par)
Difference is last filter, with three new parameters: cinqv, meanv and nonentecinqv given in input of the function, and are columns of DATA dataframe.
The error :
OperationalError: near "?": syntax error

Update Values in Mysql

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 get a map of all data types from pymysql.cursor.description?

For sql_select_query = 'select * from table', you can use pymysql python module to connect to MySql database and cursor.description to extract values.
def conn():
myDb=pymysql.connect(server,user,password,database)
return myDb
dbc = conn() #database connection
dbCursor = dbc.cursor() # cursor
# gathers all column field names and their type
field_names_and_type = [desc[:2] for desc in dbCursor.description]
Example output:
print(field_names_and_type)
[('ItemId', 1), ('ItemName', 3)]
type 1 is nvchar
type 3 is int
Question: how to i map these?
I've checked pymysql docs but could not find the mapping for cursor.description output.

Pymysql type codes are defined in pymysql.constants.FIELD_TYPE
DECIMAL = 0
TINY = 1
SHORT = 2
LONG = 3
FLOAT = 4
DOUBLE = 5
NULL = 6
TIMESTAMP = 7
LONGLONG = 8
INT24 = 9
DATE = 10
TIME = 11
DATETIME = 12
YEAR = 13
NEWDATE = 14
VARCHAR = 15
BIT = 16
JSON = 245
NEWDECIMAL = 246
ENUM = 247
SET = 248
TINY_BLOB = 249
MEDIUM_BLOB = 250
LONG_BLOB = 251
BLOB = 252
VAR_STRING = 253
STRING = 254
GEOMETRY = 255
CHAR = TINY
INTERVAL = ENUM

Python query wrong output

I had a query that should return all permittedUserId when userId matched with what was supplied my the user. I wanted to use the result of the query for a different query and noticed I kept getting the same output.
sql = "SELECT permittedUserId FROM PermittedSharedUSer WHERE PermittedSharedUSer.userId = %s"
Here is what the table looks like
Why do I get this output?
[{'num': 3}, {'num': 3}, {'num': 3}, {'num': 3}]
The output I want should be number 7,6,2,3, not 3,3,3,3
Here's the whole code:
self.ensureConnected()
applicationUser = (content['userID'], )
sql = "SELECT permitedUserId FROM PermittedSharedUSer WHERE PermittedSharedUSer.userId = %s"
crows = self.cursor.execute(sql, applicationUser)
result = self.cursor.fetchall()
if(len(result) > 0 ):
d = collections.OrderedDict()
objects_list = []
for row in result:
d['num'] = row[0]
#sqlname = "SELECT name , username FROM Users WHERE Users.id=%s"
#valname = (row[0],)
#self.cursor.execute(sqlname,valname)
#resultName = self.cursor.fetchall()
#for row2 in resultName:
# d['name'] = row2[0]
# d['username'] = row2[1]
objects_list.append(d)
return (json.dumps(dict(data = objects_list), default=str), 200)
elif(crows ==None):
return (json.dumps(dict(data = "empty")), 200)

Here's a sample table which I created in SQL
and the code to fetch the data from it
import mysql.connector
db = mysql.connector.connect(host='localhost',user='root',passwd='5548',database='test')
cursor =db.cursor()
n='1'
cursor.execute("select permission from test where userid = %s",(n,))
v = cursor.fetchall()
for i in v:
print(i[0],end=" ")
and the output is
7 6 2 4
Hence, the way you are establishing the connection and retrieving the data is fine.
Looking at the for loop - I can see the probable error
objects_list.append(d)
should be
objects_list.append(d['num'])
The code should look like this
applicationUser = (content['userID'], )
sql = "SELECT permitedUserId FROM PermittedSharedUSer WHERE PermittedSharedUSer.userId = %s"
crows = self.cursor.execute(sql, applicationUser)
result = self.cursor.fetchall()
if(len(result) > 0 ):
d = collections.OrderedDict()
objects_list = []
for row in result:
d['num'] = row[0]
#sqlname = "SELECT name , username FROM Users WHERE Users.id=%s"
#valname = (row[0],)
#self.cursor.execute(sqlname,valname)
#resultName = self.cursor.fetchall()
#for row2 in resultName:
# d['name'] = row2[0]
# d['username'] = row2[1]
objects_list.append(d['num'])

Python clipping database returned variables

I'm busy with a script to get some data from the database and arrange it for output later and I would like to know how to clip the variables being returned
I have my script
# CONNECT TO DATABASE
#=====================================================================
varPgSQL = connectToDatabase()
# PREPARE SQL STATEMENTS
#=====================================================================
cur_users = varPgSQL.cursor()
cur_users.execute("prepare cur_users as " +
"select * from users " +
"where usr_idno > $1")
cur_details = varPgSQL.cursor()
cur_details.execute("prepare cur_details as " +
"select * from details " +
"where dtl_usr_idno = $1")
# EXECUTE SQL STATEMENTS
#=====================================================================
la_results = []
cur_users.execute("execute cur_users(%s)", str(0))
for lr_user in cur_users:
cur_details.execute("execute cur_details(%s)", str(lr_user[0]))
for lr_detail in cur_details:
# STORE RESULTS
la_results.append({
"usr_idno": lr_user[0],
"usr_name": lr_user[1],
"dtl_usr_idno": lr_detail[0],
"dtl_usr_accn": lr_detail[1],
"dtl_usr_accs": lr_detail[2]
})
# CLOSE CONNECTION
#=====================================================================
varPgSQL.close()
# CHECK RESULTS
#=====================================================================
for lr_result in la_results:
print(
" | " +
lr_result["usr_name"] +
" | " +
lr_result["dtl_usr_accn"] +
" | " +
lr_result["dtl_usr_accs"] +
" | "
)
The output of this code though is not clipping the variables, the output is
| mavis | service acc | active |
Which is what I expected because it's the length of the fields in the database but is it possible to clip the variables for output to achieve
| mavis | service acc | active |

If the gaps are being created by whitespace you can use the built in String method strip()
If its is a database artifact you may have to give us more information.
