python对Oracle数据库接口cx_Oracle

python对oracle数据库的操作用cx_oracle库

操作简单，例如

#例子
import cx_oracle

con = cx_oracle.connect("pythondemo/welcome@192.168.188.11:1521/std1")
cur = con.cursor()

rows = [ (1, "first" ), (2, "second" ),
         (3, "third" ), (4, "fourth" ),
         (5, "fifth" ), (6, "sixth" ),
         (7, "seventh" ) ]

cur.execute("truncate table mytab")
cur.executemany("insert into mytab(id, data) values (:1, :2)", rows)
con.commit()

cur.execute('select * from mytab')
res = cur.fetchall()
print(res)

cur.close()
con.close()

例2

import pandas as pd
import cx_oracle

con = cx_oracle.connect("scott","tiger","192.0.2.21:1521/std1")

d = pd.read_sql('select * from emp',con)
