Python 2.5开始提供了对sqlite的支持,带有sqlite3库.
没有sqlite的版本需要去PySqlite主页上下载安装包.
import sqlite3 #导入模块
cx = sqlite3.connect("d:\\test.db")cu = cx.cursor()#这样定义了一个游标。
游标对象有以下的操作:
import sqlite3 #导入模块
cx = sqlite3.connect("d:\\test.db") cu=cx.cursor()
cu.execute("""create table catalog ( id integer primary key, pid integer, name varchar(10) UNIQUE )""") cu.execute("insert into catalog values(0, 0, 'name1')")
cu.execute("insert into catalog values(1, 0, 'hello')")
cx.commit()cu.execute("select * from catalog")
print cu.fetchall()cu.execute("select * from catalog where id = 1")
print cu.fetchone() cu.execute("update catalog set name='name2' where id = 0")
cx.commit()
cu.execute("select * from catalog")
print cu.fetchone() cu.execute("delete from catalog where id = 1")
cx.commit()
cu.execute("select * from catalog")
cu.fetchall()
#cu.close()
#cx.close()
