（转发）python sqlalchemy中create_engine用法

用法 

engine = create_engine('dialect+driver://username:password@host:port/database')

dialect -- 数据库类型

driver -- 数据库驱动选择

username -- 数据库用户名

password -- 用户密码

host 服务器地址

port 端口

database 数据库

 

 

engine = create_engine('postgresql+psycopg2://scott:tiger@localhost/mydatabase')

pg8000

engine = create_engine('postgresql+pg8000://scott:tiger@localhost/mydatabase')</pre>

MySQL

The MySQL dialect uses mysql-python as the default DBAPI. There are many MySQL DBAPIs available, including MySQL-connector-python and OurSQL:

<pre style="margin: 5px 0px; padding: 10px; font-size: 1.2em; border: 1px solid rgb(204, 204, 204); box-shadow: rgb(223, 223, 223) 2px 2px 3px; overflow: auto; line-height: 1.3em;"># default
engine = create_engine('mysql://scott:tiger@localhost/foo')

mysql-python

engine = create_engine('mysql+mysqldb://scott:tiger@localhost/foo')

MySQL-connector-python

engine = create_engine('mysql+mysqlconnector://scott:tiger@localhost/foo')

Oracle

create_engine('oracle://scott:tiger@127.0.0.1:1521/sidname')

 

MSSQL

engine = create_engine('mssql+pyodbc://scott:tiger@mydsn')

engine = create_engine('mssql+pymssql://scott:tiger@hostname:port/dbname')</pre>

下面mysql作为例子

yconnect = create_engine('mysql+mysqldb://root:password@host:port/db?charset=utf8')  
pd.io.sql.to_sql(DataResultDF,'tablename', yconnect, schema='db', if_exists='append')
