示例:python用dataset导入900w条数据到oracle
dataset可以批量导入数据库,以dict结构就可以导入数据库
import dataset
import logging
import time
def handle_txt():
ids = []
uids= []
with open('./xxx.txt',mode='r',encoding="utf8") as f:
rows = f.readlines()
for row in rows:
text = row.split(',')
ids.append(text[0])
uids.append(text[1])
logging.StreamHandler(stream=None)
db = dataset.connect('oracle://"用户名":“密码”@“数据库连接名”')
table = db['tablename']
import_data = []
data = zip(ids,uids)
data = list(data)
for i in data :
start_time = time.time()
import_data.append(dict(id=i[0], uid=i[1]))
if len(import_data) == 20000:
table.insert_many(import_data)
import_data = []
end_time = time.time()
cost_time = end_time - start_time
logging.info("%s" % cost_time)
import_data = []
start_num = len(data) % 20000
print(start_num)
data_save = data[-start_num:]
for i in data_save:
import_data.append(dict(id=i[0], uid=i[1]))
table.insert_many(import_data)
db.commit()
if __name__ == '__main__':
data= handle_txt()
