如何在Mysql中使用User_input输入表名？

Question

Enter DATA Into DATABASE

import MySQLdb
import time
import datetime
import calendar
localtime = time.asctime(time.localtime(time.time()))
print "Local current time :", localtime

Open database connection

db = MySQLdb.connect("localhost","root","","attendence" )

prepare a cursor object using cursor() method

cursor = db.cursor()

Enter subject

subject=raw_input("Enter Subject Name:")

Drop table if it already exist using execute() m ethod.

sql="DROP TABLE IF EXISTS %s"%(subject)
cursor.execute(sql)

Create table as per requirem ent

sql1= """CREATE TABLE %s (Sl_No. INT(200),NAME CHAR(20))"""%(subject)
cursor.execute(sql)

disconnect from server

db.close()

Answer 1

Surely,you can do so.But it donot recommend.And your code have some error,such as Sl_No. is invalid col name. So i change your code a little.

import MySQLdb
import time
import datetime
import calendar
localtime = time.asctime(time.localtime(time.time()))
print ("Local current time :", localtime)
db = MySQLdb.connect("localhost","root","","attendence" )
cursor = db.cursor()
subject = raw_input("Enter Subject Name:")
cursor.execute("show tables")
dele = "DROP TABLE IF EXISTS {tab}".format(tab=subject)
cre  = """CREATE TABLE {tab} (Sl_No INT(200),NAME CHAR(20))""".format(tab=subject)

def commit(sql):
    cursor.execute(sql)
    db.commit()

if subject.strip() in [tab[0] for tab in cursor.fetchall()]:
    commit(dele)
    commit(cre)
else:
    commit(cre)
db.close()

Answer 2

db = MySQLdb.connect（“ localhost”，“ root”，“ reverend”，“ TESTDB”）
