//引用cx_Oracle>>> import cx_Oracle;
//Oracle连接，输入用户名密码和网络服务名
>>> conn=cx_Oracle.connect('sde/sde@orcl_165')
//定义参数获得游标
>>> cursor=conn.cursor();
//建立一个查询语句
>>> sql="select * from owner where objectid<3"
//获得游标对象
>>> cursor.execute(sql)
<__builtin__.OracleCursor on
//获得游标指向的rows
>>> rows =cursor.fetchall()
//循环row
>>> for row in rows:
//输出row信息
... print row

//Make a connection to the SQL Server database using database authentication or Windows authentication by passing in the //appropriate parameters such as the server name, user ID (UID) and password (PWD)://Database authentication string:
con = pyodbc.connect('DRIVER={SQL Server};SERVER=Prod1SQL2008R2;DATABASE=SDE;UID=sa;PWD=sa')
//Windows authentication string:
con = pyodbc.connect('Trusted_Connection=yes', driver = '{SQL Server}',server = ‘Prod1SQL2008R2 ‘, database = ‘SDE')
//Define a parameter to access the cursor method:
cur = con.cursor()
//Create a query string:
querystring = "select * into ParcelsA from ParcelsB"
//Pass the query string into the cursor method:
cur.execute(querystring)
con.commit()
