a3947fb244 Added support for binding native integers which has a slight performance 
advantage.

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)

8c1e6f68e4 Added support for binding boolean values to PL/SQL booleans -- a feature that 
is only available in Oracle 12.1 and higher.
 2016-01-14 21:41:36 -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

3d160bf54a Remove conditional statements looking for SQLT_BFLOAT since that was 
introduced in 10g Release 1 and cx_Oracle does not support anything earlier
than that anyway!
 2015-04-25 19:31:03 -06:00

98886fe3bc Correct execution of tests with Oracle 11g client. 2015-04-03 22:50:31 -06:00
Anthony Tuininga
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.

faadbe4730 Remove code specific to strings being 4000 characters now that Oracle 12c has 
the ability to have strings up to 32k characters. This implies that using
setinputsizes() is necessary if a long string type is desired as this will not
occur automatically when the string exceeds 4000 characters. Tests are tidied
up to remove the "p_" prefix from all bind variables.

b353be865a Booleans are subclassed to integer so ensure that the boolean is checked first; 
this wasn't a problem in Python 2.x but has become one in Python 3.x.
 2014-08-05 15:50:05 -06:00

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

4838055084 Ensure that in Python 3 NCHAR and NVARCHAR2 and NCLOB columns are retrieved 
properly without conversion issues. Thanks to Joakim Andersson for pointing
out the issue and the possible solution.

96a3468db6 Added suport for LONG_UNICODE which is a type that is used to handle long 
unicode strings. These are not explicitly supported in Oracle but can be used
to bind to NCLOB, for example, without getting the "unimplemented or
unreasonable conversion requested" error.

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.

b1b4c403fb Added support for creating an object variable via a named type -- the first 
step on the road to adding full object support.

f3282b2ae2 Added check for attempts to call executemany() with arrays which are not 
supported by the OCI; thanks to Amaury Forgeot d'Arc for the suggestion.

1ef0f27b70 Change order of assignment in order to make VC++ happier. 2009-09-28 15:51:41 +00:00

04a4428fee Add additional cast as requested by Marco de Paoli in order to support 
compiling with Microsoft Visual C++ 2008.

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.

6e899f435e NCLOB variables need to be retained even in Unicode mode as Oracle will not 
allow you to read/write those type of LOB values with SQLCS_IMPLICIT for
reasons known only to itself.

231377127e Added support for interval day to second in Oracle, represented as Python 
datetime.timedelta objects.

699d1eef58 Reverse the comparison for character data or bad things can happen! 2008-10-17 04:06:29 +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.

c2fbe9a801 Further work toward supporting Python 3.x. 2008-10-16 21:37:08 +00:00

60cd74aed4 Use sb4 instead of int in order to handle 64-bit platforms properly. 2008-10-16 16:31:35 +00:00

4d2a8c57de Dropped support for Python 2.3. 2008-10-16 04:19:14 +00:00

5bf582907c Remove remaining references to PyString_* functions to enable support for full 
Unicode mode and eventual support for Python 3.x.

d8f9b4687e Tweaks to make pickier compilers happy and handle wide unicode correctly. 2008-10-16 02:31:04 +00:00
Anthony Tuininga
515bca0f96 All test cases now run correctly in Unicode mode. There are still additional 
things that need to be dealt with but the majority of the code has now been
transformed to use either Unicode or encoded strings with Oracle.

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

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.

dcb996e338 Explicitly drop support for versions earlier than Python 2.3 with the advent 
of Python 2.6.
 2008-10-10 04:30:53 +00:00
Anthony Tuininga
c424a823a8 First cut at adding support for full unicode which is required by Python 3 but 
the code is structured so that this can be done with Python 2.x as well if
desired; the only thing currently working is the determination of error
messages.

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

1a5c2bfaa7 To be consistent with the output converter always call the input converter 
even if the value coming is is null.

c857cb1f0b Fix reference to input type handler. 2008-10-09 13:32:32 +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
Anthony Tuininga
8e506ceeea Make a base type for all variables so that the attributes and methods are 
shared without having to specify such; remove references to methods that get
the attributes and methods dynamically since these are deprecated in Python 2.6
and above. Thanks to Amaury Forgeot d'Arc for the initial patch.
 2008-10-02 19:00:06 +00:00

243849a5ff Use Py_TYPE to determine the type of an object rather than referencing the 
attribute directly as suggested by Amauary Forgeot d'Arc.

abecfc7631 Tweaked source as suggested by Amaury. 2008-10-02 14:31:59 +00:00

e0e7675264 Verify that the variable returned can support the fetch. 2008-09-30 22:04:25 +00:00
Anthony Tuininga
ea3def86c5 Added support for returning unicode values for nchar and nvarchar data and 
for binding unicode. Thanks to Amaury Forgeot d'Arc for the initial patch.

6b1a551997 Use a cx_Oracle.Error instance rather than a string to hold the error as 
requested by Helge Tesdal.
