Synopsis
I am developing an integration process, using Python Win 2.5.4, that performs both geo- and tabular manipulations, and the process must work with standard Oracle 10g R2 databases (non-SDE databases) from across the enterprise. It works well in this regards.
However, we also have an Oracle 10g R 2 'ASP' GDB in an enterprise SDE, and cx_Oracle query results appear to be returning unicode when in fact the unicode is part of the output string.
Specifics:
Here's the crux of how 'cx_Oracle' is used to return results from an Oracle table within our ASP GDB:
>>> import os
>>> os.environ["NLS_LANG"] = "AMERICAN_AMERICA.WE8MSWIN1252"
>>> import cx_Oracle
>>> import string
>>> oraConnectAsp = cx_Oracle.Connection(oraUserAsp + "/" + oraPwAsp + "@" + oraDbAsp)
>>> oraCursorAsp = oraConnectAsp.cursor()
>>> whereCol = "a2a2_" + string.lower(envArg)
>>> sql = "SELECT sys_acct FROM " + tblAspNotify + " WHERE " + whereCol + " = 'Y'"
>>> print sql
SELECT sys_acct FROM ASP.ASP_Notification WHERE a2a2_dev = 'Y'
>>> oraCursorAsp.execute(sql)
<__builtin__.OracleCursor on <cx_Oracle.Connection to asp@SDEPID>>
>>> statusMsgList = oraCursorAsp.fetchall()
>>> print statusMsgList
[(u'nmassaro',), (u'smitchel',)]
>>> print statusMsgList[0]
(u'nmassaro',)
The output looks like unicode but in fact it is part of the string...
>>> x = statusMsgList[0]
>>> x
(u'nmassaro',)
>>> print x
(u'nmassaro',)
...whereas unicode behaves as follows:
>>> x = u"nmassaro"
>>> x
u'nmassaro'
>>> print x
nmassaro
As stated, using 'cx_Oracle' to connect to a standard Oracle 10g R2 database (ie, a non SDE database) it is not an issue. Here's an example of the results of a query on a table in an AGED database:
>>> oraConnectAge = cx_Oracle.Connection(oraUserAge + "/" + oraPwAge + "@" + oraDbAge)
>>> oraCursorAge = oraConnectAge.cursor()
>>> itmStr = "upunttime, uphour, uphour, upminute, usleep, udependency"
>>> sql = "SELECT " + itmStr + " FROM " + tblDb_UpdtParam + " WHERE uname = 'A2A2'"
>>> print sql
>>> oraCursorAge.execute(sql)
<__builtin__.OracleCursor on <cx_Oracle.Connection to geocode@AGED>>
>>> oraResultAge = oraCursorAge.fetchall()
>>> print oraResultAge
[('01:09:00', 1, 1, 9, 30, 'A2A1_FINISHED SW_FINISHED')]
>>> updtDependency = string.split(str(oraResultAge[5]))
>>> print updtDependency
['A2A1_FINISHED', 'SW_FINISHED']
>>> print str(updtDependency[0]) + " " + str(updtDependency[1])
A2A1_FINISHED SW_FINISHED
If the query results were truly Unicode I could convert to ASCII, but when what appears to be Unicode is part of the output then the onus is a lot of string manipulation- not desirable.
Ideas how to return either simple ASCII or, at the worst, true Unicode?
Thanks-
