python导入csv数据-使用python将csv文件导入Mysql数据库
这是我的代码:#!/usr/bin/pythonimport MySQLdbimport csvdb = MySQLdb.connect(host="host", # The Hostuser="username", # usernamepasswd="pwd", # passworddb="databasename"
这是我的代码:#!/usr/bin/python
import MySQLdb
import csv
db = MySQLdb.connect(host="host", # The Host
user="username", # username
passwd="pwd", # password
db="databasename") # name of the data base
sqlLoadData = 'LOAD DATA LOCAL INFILE "csv?_file_name.csv" INTO TABLE tablename '
sqlLoadData += 'FIELDS TERMINATED BY "," LINES TERMINATED BY " "'
sqlLoadData += 'IGNORE 1 LINES'
sqlLoadData += 'ENCLOSED BY '"' ESCAPED BY "\" '
try:
curs = db.cursor()
curs.execute(sqlLoadData)
resultSet = curs.fetchall()
except StandardError, e:
print e
db.rollback()
db.close()
我收到一条错误消息:您的SQL语法有错误;请检查与Mysql服务器相关的手册。
当我移除部件sqlLoadData += 'ENCLOSED BY '"' ESCAPED BY "\" '时,一切工作正常。我使用最后一部分只是为了从值中删除引号。
我也试过:cursor = mydb.cursor()
reader = csv.reader(open('Cumulative.csv', 'rb'))
reader.next() for row in reader[1:]:
cursor.execute('INSERT INTO Cumulative (C1, C2, C3, C4, C5, C6) VALUES(%s, %s, %s, %s, %s, %s)', row)
cursor.commit()
关闭与数据库的连接。cursor.close()
我只想删除引号,这样整数字段将支持数据。所以带引号的“1”将被视为字符串而不是整数
有人能帮我理解这个吗?
谢谢!
