python通过jdbc连接数据库

python要访问sybase或oracle数据库，尝试通过odbc以及pyodbc等方式去访问数据库，一直没有成功，通过JayDeBeApi模块调用 java jdbc 成功访问数据库。

1、安装 jaydebeapi

pip install JayDeBeApi

2、连接Sybase数据库

import jaydebeapi
import pandas as pd
 
url='jdbc:jtds:sybase://127.0.0.1:5000/db;loginTimeout=1;socketTimeout=15000;charset=GB2312'
user='sa'
password='password'
dirver='net.sourceforge.jtds.jdbc.Driver'
jarFile='jtds-1.2.5.jar'
sqlStr='select * from v_bill'
conn=jaydebeapi.connect(dirver,url,[user,password],jarFile)
curs = conn.cursor()
data=pd.read_sql_query(sqlStr,conn)
print(data)
curs.close()
conn.close()

调用存储过程的方式：

import jaydebeapi
import pandas as pd
 
url='jdbc:jtds:sybase://127.0.0.1:5000/db;loginTimeout=1;socketTimeout=15000;charset=GB2312'
user='sa'
password='password'
dirver='net.sourceforge.jtds.jdbc.Driver'
jarFile='jtds-1.2.5.jar'
conn=jaydebeapi.connect(dirver,url,[user,password],jarFile)
curs = conn.cursor()
curs.execute('db..proc_Test')
result=curs.fetchall()
print(result)
curs.close()
conn.close()

3、连接Oracle数据库

import jaydebeapi
 
url='jdbc:oracle:thin:@192.168.1.63:1521:orcl'
user='dbuser'
password='password'
dirver='oracle.jdbc.OracleDriver'
jarFile='ojdbc6.jar'
sqlStr='select * from dual'
conn=jaydebeapi.connect(dirver,url,[user,password],jarFile)
curs = conn.cursor()
curs.execute(sqlStr)
result=curs.fetchall()
print(result)
curs.close()
conn.close()
