Answer 1

Here the code.

import csv
import sys
import cx_Oracle

db = cx_Oracle.connect('user/pass@host:1521/service_name')
SQL = "select * from dual"
print(SQL)
cursor = db.cursor()
f = open("C:\dual.csv", "w")
writer = csv.writer(f, lineterminator="\n", quoting=csv.QUOTE_NONNUMERIC)
r = cursor.execute(SQL)

#this takes the column names
col_names = [row[0] for row in cursor.description]
writer.writerow(col_names)

for row in cursor:
   writer.writerow(row)
f.close()
