Question

我想将文本文件数据导出到MySQL数据库

import MySQLdb
import re

conn = MySQLdb.connect (host = "127.0.0.1", user = "root", passwd = "123456")
mycursor =conn.cursor()
mycursor.execute("CREATE DATABASE IF NOT EXISTS  EMP")
mycursor.execute("USE  EMP")
mycursor.execute("CREATE TABLE IF NOT EXISTS emp_details  (Id VARCHAR(255) , Firstname VARCHAR(255),Lastname VARCHAR(255),department VARCHAR(255),salary VARCHAR(255)) ")

f = open("new.txt", "rb")
print (f.next())

for x in f:

  mycursor.execute("INSERT INTO emp_details VALUES (%s,%s,%s,%s,%s)",x)
  conn.commit()

print(mycursor.rowcount, "record inserted.")

我遇到错误

query = query % args
TypeError: not all arguments converted during string formatting

this is what my text file data looks like

Answer 1

以逗号分隔行，因为必须为该执行字符串提供5个参数。另外，您应该明确命名这些列：

mycursor.execute("INSERT INTO emp_details (Id, Firstname, Lastname, department, salary) VALUES (%s,%s,%s,%s,%s)", x.split(","))

Answer 2

在您的代码中，您没有提到列以及如何拆分数据

此代码非常好

import MySQLdb
import re

conn = MySQLdb.connect (host = "127.0.0.1", user = "root", passwd = "123456")
mycursor =conn.cursor()
mycursor.execute("CREATE DATABASE IF NOT EXISTS  EMP")
mycursor.execute("USE  EMP")
mycursor.execute("CREATE TABLE IF NOT EXISTS emp_details  (Id VARCHAR(255) , Firstname VARCHAR(255),Lastname VARCHAR(255),department VARCHAR(255),salary VARCHAR(255)) ")

f = open("new.txt", "rb")
f.next()


for x in f:

  print (x)
  sql=("INSERT INTO emp_details (Id,Firstname,Lastname,department, salary) VALUES (%s,%s,%s,%s,%s)")
  var=( x.split(","))
  mycursor.execute(sql,var)
  conn.commit()


print(mycursor.rowcount, "record inserted.")
