如何将表导出为csv或excel格式

Question

I need to export a oracle table to a csv/excel file format (along with the column headings). A solution through cx_oracle or through sqlplus welcome.

Python code from the comment:

con = cx.connect() 
cur = con.cursor() 
printer = cur.execute(sqlcode) 
con.commit() 

Answer 1

perhaps use csv module (from standard library):

import csv
cursor = connection.cursor() # assuming you know how to connect to your oracle db
cursor.execute('select * from table_you_want_to_turn_to_csv')
with open('output_file.csv', 'wb') as fout:
    writer = csv.writer(fout)
    writer.writerow([ i[0] for i in cursor.description ]) # heading row
    writer.writerows(cursor.fetchall())

If you have loads of data, unroll the fetchall() into a loop.

Happy trails!

要创建XLS文件，请使用python-excel项目中的xlwt模块。

对于非python解决方案，Tom Kyte有一些优秀的脚本， 可以使用PL / SQL（UTL_FILE），SQL * Plus和Pro * C 生成CSV文件 。
