cx-oracle

I'm trying to use cx_Oracle module in python to access a remote database and insert or delete rows in tables. BTW I have downloaded oracle instant client 11.1 and also odbc and sqlplus versions. I have set environment variables ORACLE_HOME and TNS_ADMIN to directory I have unzipped files there and add this this directory to the PATH variable. As I googled I think there should be some .ora files but I can't find them. I can use sqlplus commands from command line, but my main problem is that I can't install and use cx_Oracle . I don't want to use any command line scripts; I just want to use cx

I want to execute an Oracle PL/SQL statement via cx_oracle in Python. Code looks like this: db = cx_Oracle.connect(user, pass, dsn_tns) cursor = db.cursor() ... sel = """ DECLARE c NUMBER := 0.2; mn NUMBER := 1.5; res NUMBER; BEGIN res := c+mn/6.; END; """ try: cursor.execute(sel) print "PL/SQL successful executed ..." except cx_Oracle.DatabaseError as e: err, = e.args print "\n".join([str(err.code),err.message,err.context]) The code is running without problems, but is there any chance to get the result back to Python? You can bind input and output variables to the block like so. import cx

I'm creating a RESTful API which needs to access the database. I'm using Restish, Oracle, and SQLAlchemy. However, I'll try to frame my question as generically as possible, without taking Restish or other web APIs into account. I would like to be able to set a timeout for a connection executing a query. This is to ensure that long running queries are abandoned, and the connection discarded (or recycled). This query timeout can be a global value, meaning, I don't need to change it per query or connection creation. Given the following code: import cx_Oracle import sqlalchemy.pool as pool conn

I'm trying to install the cx_Oracle for Python 2.6, but it is failing. I don't know enough about C or MS Vis. Studio's compiler to even approach fixing it myself. This is what is output on the command line: C:\pydev\cx_Oracle-5.0.1>C:\python26\python setup.py install running install running build running build_ext building 'cx_Oracle' extension C:\Program Files\Microsoft Visual Studio 9.0\VC\BIN\cl.exe /c /nologo /Ox /MD /W3 /GS- /DNDEBUG -IC:\Oracle\instantclient\sdk\include -IC:\p ython26\include -IC:\python26\PC /Tccx_Oracle.c /Fobuild\temp.win32-2.6-11g\Release\cx_Oracle.obj -DBUILD

I have a connection string that looks like this con_str = "myuser/mypass@oracle.sub.example.com:1521/ora1" Where ora1 is the SID of my database. Using this information in SQL Developer works fine, meaning that I can connect and query without problems. However, if I attempt to connect to Oracle using this string, it fails. cx_Oracle.connect(con_str) DatabaseError: ORA-12514: TNS:listener does not currently know of service requested in connect descriptor This connection string format works if the ora1 is a service name, though. I have seen other questions that seem to have the reverse of my
