我正在从使用 ASCII 字符 254 作为分隔符的数据库中提取数据。我很困惑如何搜索为 254 返回的字符串,然后根据它创建字典?
我的蟒蛇课
import sys
sys.path.append('C:\\IBM\\UniDK\\uojsdk\\lib\\asjava.jar')
import os.path
from asjava.uniclientlibs import UniDynArray, UniDataSet
from asjava.uniobjects import UniSession, UniFile
from asjava.uniobjects import UniSubroutineException
from asjava.uniobjects.UniObjectsTokens import AT_FM
class u2py :
def __init__ (self):
self.conn = UniSession()
def get_db(self):
""" establish a connection to Unidata """
username = 'dbuser'
password = 'SuperSecretPassword'
return self.conn.connect("host", username, password, "ACCOUNT")
def close_db(self):
""" drop connection to Unidata """
if self.conn.isActive():
self.conn.disconnect()
def open_file(self,file_name,rec):
""" open a U2 file read a record and return it """
uvfile = self.conn.open(file_name)
uvrec = uvfile.read(rec)
dataset = uvrec
uvfile.close()
return dataset
def open_field(self,file_name,rec,field):
""" open a U2 file read a record and return it """
uvfile = self.conn.open(file_name)
uvrec = uvfile.readField(rec,field)
dataset = uvrec
uvfile.close()
return dataset
这是我在控制台中的代码:
from u2py import *
u2 = u2py()
c = u2.get_db() #creates the connection to the DB
c #actually makes the connection
rec = u2.open_file('SOFILE','SO133700')
print rec
然后将其打印到屏幕上:
ZZZAA■XN3■CEL■931819501■20020215■BWI/PP■■
“■”实际上是字段标记 chr(254)
编辑:
当我使用这个时:
>>>rec = u2.open_file('SOFILE','SO133699').split(chr(254))
我收到这个错误
Traceback (most recent call last):
File "<stdin>", line 1, in <module>
AttributeError: 'asjava.uniclientlibs.UniString' object has no attribute 'split'
编辑和最终答案:
使用 UniObjects Java
rec.toString().split(chr(254))
成功!!!!
