How to Retrieve SQL Result Column Value Using Column Name in Python

Python/Pandas How to get columns names AND values from a sql query

I'm not sure about using a cursor, but I use the following format when doing this and it works.

import mysql.connector
import pandas as pd

db_conn = mysql.connector.connect(
  host="SQLServer",
  user="sqlusr",
  password="usrpasswd",
  database="sqldb"
)

query = """SELECT * FROM direction_prix_proxi.matrice_sigma
            LEFT JOIN direction_pri.trans_int_prix_gen using(SIGMA, UV)
            LEFT JOIN direction_pri.trans_int_prix_module using(SIGMA, UV)
            LEFT JOIN direction_pri.trans_int_vol1an_hors_module using(SIGMA, UV)
            LEFT JOIN direction_pri.trans_int_vol1an_module using(SIGMA, UV);
        """

df = pd.read_sql(query, db_conn)
df.to_excel(file_path1, index = False, header=True)

How to get column names SQL in python

What work to me is:

field_names = [i[0] for i in self.cursor.description ]

How to write a table output with column names in SQL in python?

I'd recommend using pandas' built in read_sql function to read from your sql database.
This should read your header in properly and the datatypes too!

You'll need to define a sqlAlchemy connection to pass to pd.read_sql but that is simple for mssql:

from sqlalchemy import create_engine
engine = create_engine('mssql://timmy:tiger@localhost:5432/mydatabase')
connection = engine.connect()
query = "SELECT * FROM mytable"

df = pd.read_sql(query, engine)

EDIT:
As per Ratha's comment, it should be noted that the sqlAlchemy connection isn't essential for read_sql to work, and indeed, from the docs a connection is defined as:

con : SQLAlchemy connectable (engine/connection) or database string URI
or DBAPI2 connection (fallback mode)

Using SQLAlchemy makes it possible to use any DB supported by that library. If a DBAPI2 object, only sqlite3 is supported.

How to get fields by name in query Python?

Instead you can use pandas library

import pandas as pd
sql = "SELECT * FROM local"
df = pd.read_sql(sql,conn)

for index,row in df.iterrows():
    print(row['name'])

MySQL: Get column name or alias from query

cursor.description will give you a tuple of tuples where [0] for each is the column header.

num_fields = len(cursor.description)
field_names = [i[0] for i in cursor.description]

How to get column names from a SQL query?

I think that it your are searching for

cnx = mysql.connector.connect(user=DB_USER, password=DB_USER_PASSWORD, host=DB_HOST, database=DB_NAME)
cursor = cnx.cursor()
query = ("SELECT `name`, `ftp_name`, `created_at`, `status` AS `status_customer` FROM `customers"
         "WHERE `status` = %(status)s")

cursor.execute(query, { 'status': 1 })

# cursor.description will give you a tuple of tuples where [0] for each is the column header.

num_fields = len(cursor.description)
field_names = [i[0] for i in cursor.description]

print(num_fields)

print(field_names)

>>> 4
>>> [u'name', u'ftp_name', 'created_at', u'status_customer']

# OR just use this cursor function:

print(cursor.column_names)

>>> (u'name', u'ftp_name', 'created_at', u'status_customer')

Hope this helps!
