I am making a program that fetches column names and dumps the data into csv format. Now everything is working just fine and data is being dumped into csv, the problem is, I am not able to fetch headers into csv. If I open the exported csv file into excel, only data shows up not the column headers. How do I do that?
Here's my code:
import cx_Oracle
import csv
dsn_tns = cx_Oracle.makedsn(--Details--)
conn = cx_Oracle.connect(--Details--)
d = conn.cursor()
csv_file = open("profile.csv", "w")
writer = csv.writer(csv_file, delimiter=',', lineterminator="\n", quoting=csv.QUOTE_NONNUMERIC)
d.execute("""
select * from all_tab_columns where OWNER = 'ABBAS'
""")
tables_tu = d.fetchall()
for row in tables_tu:
writer.writerow(row)
conn.close()
csv_file.close()
What code do I use to export headers too in csv?
Place this just above your for
loop:
writer.writerow(i[0] for i in d.description)
Because d.description
is a read-only attribute containing 7-tuples that look like:
(name,
type_code,
display_size,
internal_size,
precision,
scale,
null_ok)
