Not only in Oracle. This is standard SQL behaviour. NULL means
"unknown", and if you compare two unknown values, the result is of
course also unknown.
However, Oracle adds an additional complication because it converts ''
(the empty string) to NULL on insert.

Yup. In addition, because that won't accept an empty string, you'll have
to use some non-empty string (e.g. '-' or '(no project)') to signify
that there is no project. (One might argue that this is better design
anyway (explicit rather than implicit).)

It can with a bitmap index. However, last time I looked (admittedly long
ago) this was an enterprise edition feature.

Obviously, the "PROJECT" column is causing the issue. NULL in Oracle
database is never equal to anything. If :7 is NULL, your "not matched"
condition is satisfied and your MERGE statement will insert a new and
exciting row. That has nothing to do with Python. The only solution is
"ALTER TABLE my_table modify(project not null)" or
"ALTER TABLE my_table add constraint project_nn check(project is not null)" I
If you already have NULL values in the PROJECT column than use "add constraint"
with NOVALIDATE option. Other than that, allowing NULL values in key columns is
a sign of bad design. Namely, Oracle cannot index NULL columns, so PROJECT IS
NULL
predicate cannot be resolved by an index.

Perhaps the issue is that NULL is not equal to anything. Oracle provides
the IS NULL function to determine if a value is NULL.
Note also you define "cur" but executemany with "cur3".
And is "rows = [tuple(x) for x in df.values]" what you want? Print it.

MERGE SQL in cx_Oracle executemany
Hi there,
I'm looking to insert values into an oracle table (my_table) using the query
below. The insert query works when the PROJECT is not NULL/empty (""). However
when PROJECT is an empty string(''), the query creates a new duplicate row
every time the code is executed (with project value populating as null). I
would like to modify my query so a new row is not inserted when all column
values are matched (including when project code is null).
I'm guessing I would need to include a "when matched" statement, but not too
sure on how to get this going. Would appreciate help with this, thanks.
```
con = cx_Oracle.connect(connstr)
cur = con.cursor()
rows = [tuple(x) for x in df.values]
cur3.executemany('''merge into my_table
using dual
on (YEAR = :1 and QUARTER = :2 and CODE = :3 and AMOUNT = :4 and DATE = :5 and
COMMENTS = :6 and PROJECT = :7)
when not matched then insert values (:1, :2, :3, :4, :5, :6, :7)
''',rows)
con.commit()
cur.close()
con.close()
```

cx_Oracle, callfunc and varray
Hi
I'm trying to return a simple array of numbers from a package using cx_oracle
(5.1.2). I believe this is possible. I've not been able to find anything that
suggest it isn't
create or replace TYPE NUMARRAY
-- Simple VArray of numbers
is VARRAY(3) OF NUMBER;
/
create or replace PACKAGE SIMPLEPACKAGE
AS
FUNCTION DoSomethingSimple(
cust_id INTEGER)
RETURN numarray;
FUNCTION DoSomethingSimpler(
cust_id INTEGER)
RETURN INTEGER;
END SIMPLEPACKAGE;
/
create or replace PACKAGE BODY SIMPLEPACKAGE
AS
FUNCTION DOSOMETHINGSIMPLE(
cust_id INTEGER)
RETURN numarray
AS
simple_array numarray := numarray();
BEGIN
simple_array.extend;
simple_array(1) := cust_id;
simple_array.extend;
simple_array(2) := cust_id;
simple_array.extend;
simple_array(3) := cust_id;
RETURN SIMPLE_ARRAY;
END DOSOMETHINGSIMPLE;
FUNCTION DOSOMETHINGSIMPLER(
cust_id INTEGER)
RETURN INTEGER
AS
BEGIN
RETURN cust_id;
END DOSOMETHINGSIMPLER;
END SIMPLEPACKAGE;
/
The python (2.7) is very simple
import cx_Oracle
if __name__ == '__main__':
with cx_Oracle.connect('soe', 'soe', 'oracle12c2/soe') as connection:
try:
cursor = connection.cursor();
ArrayType = cursor.arrayvar(cx_Oracle.NUMBER,3)
NumberType = cursor.var(cx_Oracle.NUMBER)
cursor.callfunc("SIMPLEPACKAGE.DOSOMETHINGSIMPLER", NumberType,
[99])
cursor.callfunc("SIMPLEPACKAGE.DOSOMETHINGSIMPLE", ArrayType, [99])
except cx_Oracle.DatabaseError as dberror:
print dberror
finally:
cursor.close()
The call to return works just fine. The call to return the function gives the
error
ORA-06550: line 1, column 13:
PLS-00382: expression is of wrong type
ORA-06550: line 1, column 7:

Problem in fetching blob or clob data with python and cx_oracle
It seems that when I attempt to download blob or clob data using fetchmany, it can not keep track of the LOB variable in subsequent fetch. The problem is over if I fetch one row at a time but it is not optimal. Can anyone give me an idea how to efficiently fetch columns with clob or blob data from oracle DB using python.

Doesn't make particular sense to me either, but I don't know anything about Oracle :) Glad it's working, anyhow. If nothing else, you have a clean installation of version 12, so if your v11 was wrong in some way, this simply sidestepped it. Often that's the easiest fix.

Re: cx_Oracle throws: ImportError: DLL load failed: This application has failed to start ...
Thx for all the suggestions!
I hope this doesn't come as a disappointment but it seems the final solution
was to install version 12 (instead of 11) of Oracle's instantclient and to
include the inner folder (holding OCI.DLL and related files) to "Path" and
"ORACLE_HOME".
I haven't the slightest clue why version 11 just - wouldn't - run but due to
backward compatibility it seems a stressful weekend got a happy ending anyway.

It looks like it's a path issue.
You say that msvcr80.dll is in
C:\WINDOWS\WinSxS\x86_Microsoft.VC80.CRT_1fc8b3b9a1e18e3b_8.0.50727.91_x-ww_0de56c07,

Have a look at the Windows' PATH environment variable.
===> Unlike in Linux with LD_LIBRARY_PATH, you can change PATH at runtime in
Windows, e.g
import os, sys, ctypes
if sys.platform.startswith("win"):
os.environ["PATH"] += (os.pathsep + r"c:\your\new\path")

You only have a single placeholder variable,
so your statement is equivalent to
SELECT field1,field2,field3
FROM my_table
WHERE field_3 IN ('CNI,CNP')
Presumably 'CNI,CNP' is not a valid value for field_3,
thus your query finds no records.
> suggestions?
To verify that you have the correct syntax, try it
with a single value first:
my_dict = {'location':"X",
'oracle_user':'user',
'oracle_password':'pass',
'dsn':'dsn',
'mailto':'some...@somewhere.org',
'codes':"CNI"}
It that produces some of the records you want, then the
question is really: can you somehow pass a list of values
via a single placeholder variable?
I'm, not a cx_Oracle expert, but I think the answer is "no".
If you want to pass exactly two values, then the work-around
would be to pass them in separate variables:
my_dict = {'location':"X",
'oracle_user':'user',
'oracle_password':'pass',
'dsn':'dsn',
'mailto':'some...@somewhere.org',
'code1':"CNI",
'code2':"CNP"}
sql = """SELECT field1,field2,field3
FROM my_table
WHERE field_3 IN (:arg_1, :arg_2)"""
args = (my_dict['code1'],my_dict['code2'])
If the number of codes can vary, you'll have to generate a
query with the correct number of placholders in it. Mabye
something like this (untested):
my_dict = {'location':"X",
'oracle_user':'user',
'oracle_password':'pass',
'dsn':'dsn',
'mailto':'some...@somewhere.org',
'codes':"Ornhgvshy,vf,orggre,guna,htyl"}
args = my_dict['codes'].split(",")
placeholders = ','.join(":x%d" % i for i,_ in enumerate(args))
sql = """SELECT field1,field2,field3
FROM my_table
WHERE field_3 IN (%s)""" % placeholders
con = cx_Oracle.connect(my_dict["oracle_user"],
my_dict["oracle_password"],
my_dict["dsn"])
cur = con.cursor()
cur.execute(sql,args)
rs = cur.fetchall()
Hope this helps,

The best place to ask questions about cx_Oracle would be the

With the bind parameter you're only passing in a single string, so
your query is effectively equivalent to:
SELECT field1,field2,field3
FROM my_table
WHERE field_3 IN ('CNI,CNP')
You can't pass an actual list into a bind parameter the way that you
would like. You need to use a separate parameter for each item in the
list. This may mean constructing the query dynamically:
in_vars = ','.join(':%d' % i for i in xrange(len(sequence_of_args)))
sql = """
SELECT field1,field2,field3
FROM my_table
WHERE field_3 IN (%s)
""" % in_vars

cx_Oracle clause IN using a variable
Hi all,
I don't know if it is the correct place to set this question, however,
I'm using cx_Oracle to query an Oracle database.
I've a problem to use the IN clause with a variable.
My statement is
sql = "SELECT field1,field2,field3
FROM my_table
WHERE field_3 IN (:arg_1)"
where arg_1 is retrive by a dictionary
that is build so
my_dict = {'location':"X",
'oracle_user':'user',
'oracle_password':'pass',
'dsn':'dsn',
'mailto':'some...@somewhere.org',
'codes':"CNI,CNP"}
args = (dict['codes'],)
con = cx_Oracle.connect(my_dict["oracle_user"],
my_dict["oracle_password"],
my_dict["dsn"])
cur = con.cursor()
cur.execute(sql,args)
rs = cur.fetchall()
but it doesn't work in the sense that doesn't return anything
If i use the statment without variable
SELECT field1,field2,field3
FROM my_table
WHERE field_3 IN ('CNI','CNP')
the query works
what is wrong?
suggestions?

You're using Oracle 11 vs our v10 (we also have v8, v9 and v11 in production, but not on this HP-UX server), but I think the problem with the libnnz is the same: Oracle doesn't put correct shared library dependencies into the libnnzXX.so dynamic section header (it should list libttshXX.so as NEEDED but apperently doesn't).

Re: Trouble importing cx_Oracle on HPUX
Hi, thank you for getting back to me. Yes, our entire toolchain is 64 bit - a mix of stuff I have downloaded and built and some packages from HP (in the form of depot files) GCC was downloaded from HP, for example. I had to manually add -mlp64 to the CC and CXX lines in the Python Makefile to get it to build 64 bit Python 3. I also had to define PATH_MAX in about 5 files, because it was not resolving it, and it was just easier to add it than to spend more time trying to make it work. I hate HP-UX, BTW. Python -d did not generate any additional information, and so was not helpful (should this work?). Python -v did, however, and it came up with a number of unresolved symbols all seeming to be from libnnz11.so. I tried linking against all of the *.so files in ORACLE_HOME/lib, but I don't remember trying libttsh11 specifically. I will try it again on Monday. -- Cliff On Sat, Aug 28, 2010 at 9:11 AM, Alexander Gattin wrote: > Hello, > > On Thu, Aug 26, 2010 at 08:08:42PM -0700, Cliff > Martin wrote: > > I have just gotten done building Python 3.1.2 on > > HPUX 11.31 Itanium (IA64) using gcc 4.4.3, and > > have tried building cx_Oracle to go with it.

The dynamic loader has a list of directories where it tries to find these files; if they aren't there, then the import of cx_Oracle will fail.

No, isn't that only if I have an actual Oracle client installed (not
the instant client)?
But great tip, wasn't exactly the solution, but your question
triggered me to check the Windows environment variables*. I included
env. variable name PATH and the value ;C:\Python31;C:\MinGW\bin;C:\TEMP
\ORAIC10\bin.
Only thing I set manually in the command prompt was: SET ORACLE_HOME=C:
\TEMP\ORAIC10 , before the build.
*=I checked the setup.py script which says:
userOracleHome = os.environ.get("ORACLE_HOME")
Checking in Visual Basic::environ("path") only included info from the
Windows env. variables, and not the ones I set via the command prompt
with PATH=%PATH%;... so I reckon if it applies to VB it also does for
os.environ
I can now import without errors!
Thanks Alexander for putting me in the right direction.

As a quick workourd you can extend the LD_LIBRARY_PATH variable with the path and check if cx_Orcacle get now the lib. Lets assume you "installed" python at /opt/Python2.7a, then you need to extend the variable in this way: export LD_LIBRARY_PATH="$LD_LIBRARY_PATH:/opt/Python2.7a/lib" afterwards do the ldd again and check if the lib could be found now. If not, you've got the wrong path. Now you need to perist the changed library path. For this, you need to be root: 1. echo "/opt/Python2.7a/lib" > /etc/ld.so.conf.d/Pathon2.7a.conf 2. refresh your shared library cache with "ldconfig" Now you OS knows the new library location. But this is not clean. As Daniel mention, you should try to get a rpm. Otherwise you may get in trouble, if you install a newer Python2.7 version and forget to maintain you library paths.

I want a libpython2.7.so.1.0 generated when I've didn't read your complete mail... In addition to the steps I've described in my other mail, you need to the "configure" script, that you like to have shared libraries. So you need to add --enable-shared to your configure call: ./configure --prefix=/opt/Python2.7a --enable-shared Now you got the shared libraries in the lib folder.

Problems with cx_Oracle and Oracle 11.1 on Windows

I have a full install of Oracle (not an instant client). I know in UNIX, you have to set the LD_LIBRARY_PATH variable, but I am not sure if there is an equivalent in Windows.

cx_Oracle implements DBAPI 2.0, then you should follow the general

LOBs are an extension to DBAPI -- see

If I: python

'ORACLE_HOME': '/Users/bft228/Library/Oracle/
instantclient_10_2',
'LD_LIBRARY_PATH': '/Users/bft228/Library/Oracle/
instantclient_10_2'
If I hard-code the userOracleHome, cx_Oracle will compile, but I'm
getting errors wen attempting to connect to Oracle, like:
cx_Oracle.InterfaceError: Unable to acquire Oracle environment handle
I've been wrestling with this for quite some time. My Oracle person
assures me that my user has appropriate permissions for the schema. My
Oracle experience is pretty limited, but this seems like it's an issue
with the environment on my Mac.
Does anyone have any ideas? I would REALLY appreciate some insight.

cx_Oracle-5.0 Problem
Hello everyone, I'm Brandon Taylor, senior web developer with the University of Texas at Austin. We're using Python 2.6.1 and having a lot of difficulty getting the cx_Oracle-5.0 library to install on one of our MacBooks running OS X 10.5.6. We can get cx_Oracle to compile, but after running setup.py install and trying to import the library, we are getting an error: Traceback (most recent call last): File "", line 1, in ImportError: dlopen(/Library/Frameworks/Python.framework/Versions/2.6/ lib/python2.6/site-packages/cx_Oracle.so, 2): Symbol not found: ___divdi3 Referenced from: /Users/mas80/Library/Oracle/instantclient_10_2/ libclntsh.dylib.10.1 Expected in: flat namespace Can anyone shed some light on how we can solve this issue? It's a show stopper for us of we can not connect to Oracle from Python. Kind regards, Brandon Taylor -- http://mail.python.org/mailman/listinfo/python-list

Hi again. A further update to these issues is that I found some java
executable which seemed to execute the SQL query without hitch. My
Java isn't great but from what I could make out it seems that the
query is broken down from:
select (obj.function(value)) from table where id=blah
to:
select value from table where id=blah
obj.function(value)
So make two queries. In the first retrieve the BLOB (value) and store
it in a java.sql.blob object. Then pass this back in to the stored
procedure. I'm a bit puzzled as to why this way would work over just
performing the straight select statement. Culd it be the jdbc
connector handles BLOBs better? Anyway I was wondering if I could
implement something similar using cx_Oracle. however I am a bit stuck
on how to pass a BLOB in to the second query - specifically:
cursor.execute(obj.function(value))
where value is the BLOB. I get an error:
cx_Oracle.NotSupportedError: Variable_TypeByValue(): unhandled data
type cx_Oracle.LOB
So I wonder if I need to set something for the input type but I do not
know how to do this.
Any suggestions?
Many thanks again.

Hi all,
So I tried Rons query but unfortunately I got 0 records returned.
However I can confirm that running the select query from a client does
indeed generate the same error. Is there anything else I could try?
Otherwise I'll just get in touch with the vendor I guess.

Hi,
Sure you can. You can see the PL/SQL source from the ditionary view
ALL_SOURCE:
select text from all_source where name = 'NAME_OF_FUNCTION';

Ron's point was that you cannot fix this problem on the side of cx_Oracle because the exception occurs before cx_Oracle ever sees the result, during the execution of PL/SQL code. This is easy to verify: simply run the function the same way in sqlplus. If the problem persists, it's a bug in the function (or in the way you're calling it, or setting up the data, etc.) and you should complain to your vendor, or somehow work around the problem. Otherwise it's a cx_Oracle related problem. -- http://mail.python.org/mailman/listinfo/python-list

Hi thanks for the responses. Unfortunately the procedure in question
is from a third party vendor so I can't really debug it so I'd say I
was fairly stumped. Just out of interest how do you increase the
output buffer size with cx_Oracle?

This error is a problem with the PL/SQL, not cx_Oracle. You need to
debug obj.function to see what kind of data is being accessed and then
a data analysis of that data to understand why this error occurs. I
can tell you the function is most likely expecting characters from a
column that are numeric [0 .. 9] and is getting alpha characters.

cx_Oracle issues
Hey all. When using cx_Oracle to run a procedure like:
cursor.execute("select (obj.function(value)) from table where
id=blah")
I am getting the following error:
ORA-06502: PL/SQL: numeric or value error: character string buffer too
small ORA-06512: at line 1
Looking at cursor.description I get:
[('(obj.function(value))', , 4000, 4000, 0,
0, 1)]
Any tips - i have never seen this error before but am guessing that
the value being returned is too big for the buffer size set for the
cursor. the procedure fetches data from a LOB.
Any suggestions/confirmations?
Many thanks

There is no mode parameter to connect. use try-catch around

Python cx_Oracle and Apache
Hi,
I am trying to write a cgi program which would be executed on
browser with Apache server installed.
The program would make a connection to a database using cx_Oracle
module and display results on page.
The code is working fine on the command line but when executing it on
the browser i get the famouse "Premature end of script headers" error.
I went ahead and found the problem occuring exactly when the code is
asking for a connection to the database.
I am attaching the program for reference. Let me know if there is
anything I need to make changes to apache or any other way to overcome
this issue.

Hello,
Thanks for your reply. The secound parameter in curs.execute has to be
list. I passed only one parameter so it looks bizzare but this is
right.
Anyway i know why it was wrong. Problem is in the cx_array_string.
This type has to be INDEX BY BINARY_INTEGER I hope it will help
somebody in the future.

p_array appears to be some sort of cxOracle array, but when you pass it
to curs.execute you wrap it in a new list: [p_array]. Try removing the
parens and see what happens.

cx_Oracle + array parameter
Hello,
I'm trying to pass array as an argument into PL/SQL procedure.
According to cursor manual (http://cx-oracle.sourceforge.net/html/

array type in PL/SQL:
CREATE OR REPLACE TYPE cx_array_string is table of varchar2(200);
and simple procedure:
CREATE OR REPLACE PROCEDURE text(ret IN cx_array_string) IS
BEGIN
null;
END text;
My python code:
p_array = curs.arrayvar(cx_Oracle.STRING, ['1','3'])
curs.execute('BEGIN text( :1 ); end;', [p_array] )
And it gives me back an error:
cx_Oracle.DatabaseError: ORA-06550: line 1, column 7:
PLS-00306: wrong number or types of arguments in call to 'TEXT'
ORA-06550: line 1, column 7:
PL/SQL: Statement ignored
It's the same when i try to use callproc() instead of execute(). I've
searched whole internet with no luck. Could anyone please give me a
working example python + pl/sql how to pass string array form py to
oracle procedure, please.
Thank you!

cx_Oracle: Non-ASCII characters handling with different versions
Hi!
I have a problem with the cx_Oracle module (Oracle database access):
On a computer with cx_Oracle version 4.1 (Python 2.4.3, Oracle 10g)
I can get query results consisting of strings including non-ASCII
characters, e.g. the code example below outputs "é 0xe9" (which is
the correct ISO-8859-1 hex code for "é"). On a newer installation
with cx_Oracle 4.3.3 (Python 2.5.1, connecting to the same Oracle
10g server) these characters are interpreted as ASCII (output "e
0x65"). The database encoding is the default (and it's the same DB
in both cases anyways); I have no NLS environment environment
variables set on either system (I'm running cygwin). The HISTORY
file of my more recent cx_Oracle names a few changes related to
character sets, but noone strikes me to be relevant for this case.
There is non-ASCII data strings in a database, and I need to find a
way to get it out correctly.
Is anybody able to help me?
Thanks!

Re: cx_oracle
Hi Lukas, you will need a working oracle OCI client middleware before cx_oracle can talk to your database. The easiest nowadays is the so-called instant client, which must be available from the otn.oracle.com site (downloads might require a free registration). Try to get sql*plus working (the standard Oracle command-line client), and cx should then pose no problem. Cheers, Bernard. -- http://mail.python.org/mailman/listinfo/python-list

Hi,
I want to get an access to an oracle database.
For that I found the module cx_oracle
(http://www.python.net/crew/atuining/cx_Oracle/) and
I have installed the version 'Windows Installer (Oracle 10g, Python 2.5)'.
Now I tried to run the script in the readme file:
---
import cx_Oracle
# connect via SQL*Net string or by each segment in a separate argument
#connection = cx_Oracle.connect("user/[EMAIL PROTECTED]")
connection = cx_Oracle.connect("user", "password", "TNS")
cursor = connection.cursor()
cursor.arraysize = 50
cursor.execute("""
select Col1, Col2, Col3
from SomeTable
where Col4 = :arg_1
and Col5 between :arg_2 and :arg_3""",
arg_1 = "VALUE",
arg_2 = 5,
arg_3 = 15)
for column_1, column_2, column_3 in cursor.fetchall():
print "Values:", column_1, column_2, column_3
---
And I got an error:
---
Traceback (most recent call last):
File "C:\Python25\cal_adjustment.py", line 1, in
import cx_Oracle
ImportError: DLL load failed: Das angegebene Modul wurde nicht gefunden.

Do someone have an idea to solve the problem? A reinstall doesn't work.
