pandas读取MySql/SqlServer数据

用过的东西总是会忘记，尤其是细节，还是记下来比较靠谱。

读取MySql数据

 import MySQLdb
 import pandas as pd
 
 conn = MySQLdb.connect(host = host,port = port,user = username,passwd = password,db = db_name)
 df = pd.read_sql('select * from table_name',con=conn)
 conn.close() 

读取SqlServer数据

import pymssql

conn = pymssql.connect(host=host, port=port ,user=username, password=password, database=database)
df = pd.read_sql("select * from table_name",con=conn)
conn.close()
