本文实例讲述了Python使用cx_Oracle模块将oracle中数据导出到csv文件的方法。分享给大家供大家参考。具体实现方法如下：
?
1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 24 25 26 27 28 29 # Export Oracle database tables to CSV files # FB36 - 201007117 import sys import csv import cx_Oracle connection = raw_input("Enter Oracle DB connection (uid/pwd@database) : ") orcl = cx_Oracle.connect(connection) curs = orcl.cursor() printHeader = True # include column headers in each table output sql = "select * from tab" # get a list of all tables curs.execute(sql) for row_data in curs: if not row_data[0].startswith('BIN$'): # skip recycle bin tables tableName = row_data[0] # output each table content to a separate CSV file csv_file_dest = tableName + ".csv" outputFile = open(csv_file_dest,'w') # 'wb' output = csv.writer(outputFile, dialect='excel') sql = "select * from " + tableName curs2 = orcl.cursor() curs2.execute(sql) if printHeader: # add column headers if requested cols = [] for col in curs2.description: cols.append(col[0]) output.writerow(cols) for row_data in curs2: # add table rows output.writerow(row_data) outputFile.close()希望本文所述对大家的Python程序设计有所帮助。
