import pymssql
import pandas as pd


sql = "select TOP 50 * from [dbo].[AM4313000001] ORDER  BY  1 DESC"
conn = pymssql.connect(server='134.175.74.32', user='sa', password='JDDBM999@', database='Power4313000003')
cursor = conn.cursor()
sql2 = "insert into [dbo].[AM4313000001] VALUES ('2020-04-15 11:19:08','231.463','231.463','231.463','655.35','655.35','655.35','655.35','655.35','655.35','0.1','0.2','71335.7','71335.7','71335.7','71335.7','71335.7','71335.7','71335.7','71335.7','71335.7','71335.7','925.959','925.959','925.959','925.959','925.959','925.959','50.959','925.959','-1.959','925.959','0','925.959','0')"
cursor.execute(sql2)

df0 = pd.read_sql(sql, conn)
conn.commit()
conn.close()
df1 = pd.DataFrame(df0)
print(df0)
