[英]Export Oracle database column headers with column names into csv
I am making a program that fetches column names and dumps the data into csv format.我正在制作一个获取列名并将数据转储为 csv 格式的程序。 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.
现在一切正常,数据正在转储到 csv 中,问题是,我无法将标题提取到 csv 中。 If I open the exported csv file into excel, only data shows up not the column headers.
如果我将导出的 csv 文件打开到 excel 中,则只显示数据而不显示列标题。 How do I do that?
我怎么做?
Here's my code:这是我的代码:
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?我也使用什么代码在 csv 中导出标题?
Place this just above your for
loop:把它放在你的
for
循环之上:
writer.writerow(i[0] for i in d.description)
Because d.description
is a read-only attribute containing 7-tuples that look like:因为
d.description
是包含 7 元组的只读属性,如下所示:
(name,
type_code,
display_size,
internal_size,
precision,
scale,
null_ok)
