python使用sqlite3的简单代码

#Filename: DBcon.py
 
import sqlite3
import time
 
conn=sqlite3.connect(r'D:ExercisePythonDBexample.db')
c=conn.cursor()
c.execute("Create table if not exists stocks (date text,trans text,symbol text,qty real,price real)")
flag=raw_input("Do you wanna clean the table?(y/n):")
if flag=='y':
    c.execute("delete from stocks")
c.execute("Insert into stocks values('"+time.strftime('%Y-%m-%d %H:%m:%S')+"','Buy','Rhatd',1000,23.14)")
conn.commit()
c.execute('select * from stocks')
res=c.fetchall()
count=0
print res
print '-'*60
for line in res:
    for f in line:
        count=count+1
        print count,f,print
print '-'*60
print '-'*60
print 'There are %d records!'  %count
c.close()
conn.close()
