ab42359f26 Fix cursor.scroll() to calculate row count correctly in all situations and 
add test cases to verify that it does in fact work.

59053718be Remove memory leak when function call raises an exception. 2017-01-12 14:09:27 -07:00
Anthony Tuininga
d4eb90d848 The current position does not need to be checked upon execute (since we are 
always moving forward) and especially not since its value is always zero in
any case!

9c8cc1160b Only allow up to 10,000 arguments -- any more than that likely wouldn't work 
anyway (or be reasonable) and this prevents a possible improper memory access
from taking place if an attempt was made to pass more than 10,000 arguments.

39805c66d7 Added support for binding objects with sub objects attached to them; ensured 
that instances are created when an empty object variable is created; enhanced
test cases for binding objects.

3eeff96403 Added support for scrollable cursors. 2016-02-05 17:19:40 -07:00
Anthony Tuininga
812ad4bd25 Added support for large row counts (larger than 2 ** 32) and laid the 
groundwork for adding support for scrollable cursors.
 2016-02-05 09:34:00 -07:00

e24fa35d93 Added support for getting implicit results (available in Oracle 12.1). 2016-01-21 17:11:57 -07:00
Anthony Tuininga
c863777917 Added support for pickling/unpickling error objects; this addresses issue 23 
(https://bitbucket.org/anthony_tuininga/cx_oracle/issues/23/cx_oracle_error-is-not-un-picklable)
 2016-01-20 16:39:25 -07:00
Anthony Tuininga
8c1e6f68e4 Added support for binding boolean values to PL/SQL booleans -- a feature that 
is only available in Oracle 12.1 and higher.

31013767c6 Eliminate compiler warning. 2016-01-13 11:33:07 -07:00
Anthony Tuininga
3c36e8cde3 Added support for NCHAR, FIXED_NCHAR and LONG_NCHAR, which are the same as the 
types UNICODE, FIXED_UNICODE and LONG_UNICODE (now deprecated).
 2015-06-06 21:01:37 -06:00

85b6adeb6b Reorganize the code for handling errors so that the same code can be used for 
managing batch errors as well as raising exceptions in the ordinary case.
 2015-02-25 21:50:30 -07:00
Anthony Tuininga
fc1bc2ecda Need to use type ub4 instead of ub8 for determining number of batch errors. 2014-09-30 20:53:49 -06:00
Anthony Tuininga
633a3bcad5 Added support for retrieving batch errors. 2014-09-24 22:22:13 -06:00
Anthony Tuininga
8f6f54801c Added support for getting array DML row counts (new to Oracle 12c). 2014-09-24 20:45:06 -06:00
Anthony Tuininga
d255b7457f Expose the UNICODE, FIXED_UNICODE and LONG_UNICODE types so that in Python 3 
one can actually specify the use of the NCHAR type fields when binding or using
setinputsizes().
 2014-07-07 12:41:37 -06:00
Anthony Tuininga
6aa817956f OCI_ATTR_PARSE_ERROR_OFFSET should be of type ub2; also handle case when the 
exception has been normalized already (and with this change force the exception
to be normalized) as in that case the cx_Oracle.Error object is not directly
accessible as originally assumed (which caused a segfault to take place).

f80fc7f211 Use the actual name of the class, not a manufactured name. 2013-04-02 13:16:11 -06:00

3d0c96cb78 Set the row number for PL/SQL blocks as well as requested by Robert Ritchie. 2012-03-27 09:44:27 -06:00
Anthony Tuininga
04f1904a7d Remove "unicode" mode and simply permit unicode to be used everywhere within 
cx_Oracle; stop using "unicode" mode in the OCI as well since that appears to
have bugs in some places and doesn't really solve any problems anyway.

9be85a356c Free temporary LOBs prior to each fetch in order to avoid leaking them; thanks 
to Uwe Hoffmann for the initial patch.

0665dff62b Remove unnecessary code. 2010-11-04 16:48:33 +00:00
Anthony Tuininga
cf2da5efc8 Check the result of freeing the handle if an exception should be raised; in 
addition, null the handle so that a second attempt is not made when the cursor
is freed after close() has been called.

b1b4c403fb Added support for creating an object variable via a named type -- the first 
step on the road to adding full object support.
 2010-07-31 05:32:30 +00:00

25274ca3fb Fix error message. 2010-05-28 18:10:12 +00:00
Anthony Tuininga
0c859f8b87 Added support for named arguments in callproc() and callfunc() which make use 
of PL/SQL notation for making such calls.

1470723453 Use the OCI_ATTR_CHAR_SIZE attribute to determine the character size of the 
value retrieved rather than attempt to assume things since the database
character set plays a role in how this is determined and that information is
not readily available. Thanks to Christopher Jones for the tip.
 2009-09-15 03:55:03 +00:00
Anthony Tuininga
057f7ee133 Move the resetting of the setinputsizes flag to before the binding takes place 
so that if an error takes place and a new statement is prepared subsequently
that spurious errors will not occur.

919c5b4559 Implemented a parse error offset as requested by Catherine Devlin. 2009-05-21 04:51:00 +00:00

b32352b54c Don't lose the Python lock before all possible Python code has been executed. 2009-01-07 15:50:16 +00:00
Anthony Tuininga
c6603b324d Add new attributes size, bufferSize and numElements to variable objects, 
deprecating allocelems (replaced by numElements) and maxlength (replaced by
bufferSize); avoid increasing memory allocation for strings when using variable
width character sets and increasing the number of elements in a variable during
executemany(). Thanks to Don Reid for pointing out this issue.

607f9019d1 Call the type's tp_free and tp_alloc methods at all times in order to deal with 
inheritance properly; use "self" at all times in the constructor and destructor
routines.

4b208c603a Ensure memory is freed if the acuisition of the bind names fails entirely. 2008-11-21 16:08:51 +00:00
Anthony Tuininga
4692ae6a71 Never mind using row_factory, the signature of the method is different. 2008-10-19 04:54:53 +00:00
Anthony Tuininga
080b53f147 Use row_factory in preference to rowfactory since the builtin sqlite3 module 
does it that way and its better to be compatible with such things.
 2008-10-17 22:53:20 +00:00
Anthony Tuininga
ebc2437935 Make the bind variables and fetch variables accessible although they need to be 
treated carefully since they are used internally; return the cursor from
the execute() method as a convenience.

93bdbb7425 Replace PyBytes_ with cxString to make Python 3.x happy. 2008-10-17 03:30:07 +00:00
Anthony Tuininga
3e55613248 Replace all occurrences of PyInt_AS_LONG with PyInt_AsLong since Python 3.x 
doesn't have a separate integer type.
 2008-10-17 03:04:48 +00:00
Anthony Tuininga
5bf582907c Remove remaining references to PyString_* functions to enable support for full 
Unicode mode and eventual support for Python 3.x.

eae705cef1 Rename additional macro as suggested by Amaury Forgeot d'Arc; added additional 
support for full Unicode; in Python 2.x allow for keyword arguments which use
strings and simply convert them to Unicode on the way through.

7d67968e3a Rename macros as suggested by Amaury Forgeot d'Arc. 2008-10-14 15:55:37 +00:00
Anthony Tuininga
2e26d0beb8 Continued work on Unicode support; added new test cases for full unicode 
support within Python 2.x; move away from character semantics which Oracle is
deprecating anyway to byte semantics which should hopefully eliminate the
problem with a backend character set of UTF-8.
 2008-10-14 04:51:43 +00:00
Anthony Tuininga
45faba4a48 Further work on supporting Unicode. 2008-10-11 05:04:26 +00:00
Anthony Tuininga
dcb996e338 Explicitly drop support for versions earlier than Python 2.3 with the advent 
of Python 2.6.

4271cb4af4 If the variable creation fails, don't use the result! 2008-10-09 22:01:34 +00:00
Anthony Tuininga
a2466272b5 Expose the DATETIME variable type properly instead of using the return value 
type; thanks to Amaury Forgeot d'Arc for pointing out this discrepancy.
 2008-10-09 21:59:09 +00:00
Anthony Tuininga
08e308b83b Added support for specifying an input type handler to control what kind of 
variable is created and eliminated the leak when an output type handler would
be specified.
 2008-10-08 22:41:47 +00:00
Anthony Tuininga
79679142d2 Added support for specifying converters for both input and output. 2008-10-08 19:11:23 +00:00
