In this example, I will list a set of columns in a table using python. First we need to connect to the oracle database
username = "user"
password = "*****"
ip = "220.127.116.11"
port = 1521
SID = 'ORCL'
table = 'mytablename'
dsn_tns = cx_Oracle.makedsn(ip, port, SID)
db = cx_Oracle.connect(user,passwword, dsn_tns)
All I did was create the entry like it would appear in the tnsname.ora file then pass that information along with the username and password to the database.
Great, now we are connected to the oracle database. Now the database can be queried.
cursor = db.cursor()
results = cursor.execute("select * from %s where 1=0" % table)
[('OBJECTID', <type 'cx_oracle.number'="">, 39, 22, 38, 0, 0), ('NEWNAME', <type 'cx_oracle.unicode'="">, 50, 100, 0, 0, 1)]
Now you do not have to use arcpy to list the fields in a table. Some other ideas you could do with your enterprise database is: rename fields, create views, etc...
