Python 连接sqlserver数据库

python连接sqlserver数据库通常可以使用pymssql库和pyodbc库来实现，下面使用pyodbc展示连接的方式

database = "database"
conn_info = 'DRIVER={SQL Server};DATABASE=%s;SERVER=%s;UID=%s;PWD=%s'%(database, host, user, password)
mssql_conn = pyodbc.connect(conn_info)
mssql_cur = mssql_conn.cursor()
mssql_cur.execute("select DeviceCode,Count from [dbo].[S59M101PT10M_Aggrega]")
row = mssql_cur.fetchall()
line = pd.read_sql_query("select DeviceCode,Count from [dbo].[S59M101PT10M_Aggrega]",mssql_conn)
