python连接dm8数据库

• 一、安装dmPython
• 二、测试
• • 1.创建python测试脚本
  • 2.执行脚本
• 三、建表测试
• 问题总结

添加环境变量

[root@localhost dmPython]# vim ~/.bash_profile 
export LD_LIBRARY_PATH="$LD_LIBRARY_PATH:/dm8/bin"
export DM_HOME="/dm8"
[root@localhost dmPython]# source  ~/.bash_profile 

安装dmPython

[root@localhost dmPython]# python setup.py install

[root@localhost dmPython]# vim ConnDM.py
import dmPython
try:
  conn = dmPython.connect(user='SYSDBA', password='szoscar55@', server='localhost', port=5237)
  cursor = conn.cursor()
  print('python: conn success!')
  conn.close()
except (dmPython.Error, Exception) as err:
  print(err)

问题：

代码如下（示例）：

[root@localhost dmPython]# python ConnDM.py

[root@localhost dmPython]# vim connPython2.py
import dmPython

try:
   conn = dmPython.connect(user='SYSDBA', password='szoscar55@', server='localhost', port=5237)
   cursor = conn.cursor()
   print('python: conn success!')
   cursor.execute("create table test5(c1 int, c2 varchar)")
   cursor.execute("insert into test5 values(2,'yhy')")
   cursor.execute("select * from test5")
   res = cursor.fetchall()
   for tmp in res:
     for c1 in tmp:
       print(c1)
       print('python: select success!')
       conn.close()
except (dmPython.Error, Exception) as err:
  print(err)

1.代码缩进问题

解决：
该行代码没有缩进，添加空格缩进就可以了
