示例：基于Python DB API开发应用程序。

#Example.py
#演示基于Python开发的主要步骤，涉及连接数据库、创建表、插入数据等。
from decimal import Decimal
import yasdb

connection=yasdb.connect(
	dsn='127.0.0.1:1688',
	user='sales',
	password='sales',
)
cursor=connection.cursor()

cursor.execute("drop table if exists bind")
cursor.execute("create table bind(id int , name varchar(256))")

def bind_param():
        cursor = connection.cursor()
        cursor.execute("drop table if exists bind_param_heap_1")
        cursor.execute("create table bind_param_heap_1(a int, b double, c int)")
        cursor.execute("insert into bind_param_heap_1 values(:1, :2, 30)",(1,10))
        cursor.execute("insert into bind_param_heap_1 values(:1, :2, 40)",(2,20))
        connection.commit()
        cursor.execute("delete from bind_param_heap_1 where a=:1",(1,))
        connection.commit()
        cursor.execute("select * from bind_param_heap_1")
        cursor.execute("update bind_param_heap_1 set c=:1", (50,))
        connection.commit()
        cursor.execute("select * from bind_param_heap_1")

bind_param()

cursor.close()
connection.close()
