* Added support for Oracle REF datatype
- Added OCI_RefCreate()
- Added OCI_RefFree()
- Added OCI_RefGetObject()
- Added OCI_RefAssign()
- Added OCI_RefIsNull()
- Added OCI_RefSetNull()
- Added OCI_RefToText()
- Added OCI_RefGetHexSize()
- Added OCI_GetRef2()
- Added OCI_GetRef()
- Added OCI_BindRef()
- Added OCI_BindArrayOfRefs()
- Added OCI_RegisterRef()
- Added OCI_ElemGetRef()
- Added OCI_HandleGetRef()
- Added OCI_ObjectGetRef()
- Added OCI_ObjectGetSelfRef()
* Added some tracing features
- Added OCI_SetTrace()
- Added OCI_GetTrace()
* Extended Object API
- Fixed internal handling of null attributes (it has been rewritten)
- Modified local (transients) objects creation. Now :
* By default, all attributes are set to NULL
* Non scalar attributes must be set by calling new functions OCI_ObjectSetXXX()
- Added setters functions for non scalar object attributes
* OCI_ObjectSetDate
* OCI_ObjectSetInterval
* OCI_ObjectSetTimestamp
* OCI_ObjectSetColl
* OCI_ObjectSetObject
* OCI_ObjectSetFile
* OCI_ObjectSetLob
* OCI_ObjectSetRef
- Added Miscellaneous Object functions
* Added OCI_ObjectIsNull()
* Added OCI_ObjectAssign()
* Added OCI_ObjectGetType()
* Extended Collection elements API
- Fixed : OCI_ElemSetNull() that was only udpating null indicator
- Fixed : some functions were not checking input elem handle nullity
- Added checks on element type in OCI_ElemGetXXX() calls that throw an exception if the element type is not the same type as the one requested
- Added setters functions for non scalar element base datatypes
* OCI_ElemSetDate()
* OCI_ElemSetInterval()
* OCI_ElemSetTimestamp()
* OCI_ElemSetColl()
* OCI_ElemSetObject()
* OCI_ElemSetFile()
* OCI_ElemSetLob()
* OCI_ElemSetRef()
* Extended Bind informations
- Modified : OCI_Bind handles are now public and can be retrieved for public information
- Added OCI_GetBindCount()
- Added OCI_GetBind()
- Added OCI_GetBind2()
- Added OCI_BindGetName()
- Added OCI_BindGetType()
- Added OCI_BindGetSubtype()
- Added OCI_BindGetStatement()
- Added OCI_BindGetData()
- Added OCI_BindGetDataCount()
- Added OCI_BindGetDataSize()
- Added OCI_BindGetDataSizeAtPos()
- Added OCI_BindSetDataSize()
- Added OCI_BindSetDataSizeAtPos()
- Added OCI_SetNull2()
- Added OCI_SetNullAtPos2()
- Extended OCIBindxxx() calls satefy :
* An error OCI_ERR_BIND_ALREADY_USED is now raised if the bind name or position is already binded to the statement
* With the bind mode by position, provided bind indexes <= 0 and > OCI_BIND_MAX will cause an error OCI_ERR_OUT_OF_BOUNDS
- Extended binds/registers limits :
* OCI implements the SQL returning clause through binds operations
* OCILIB wraps the result of the returning clause within OCI_Resultet object but has to use internal binds to create its resultset
* Prior to v3.1.0, OCI_BIND_MAX (default 512) was the maximum of OCI_bindxxx() including OCI_Registerxxx() that an OCI_Statement could handle
* With v3.1.0, OCILIB can handle OCI_BIND_MAX user binds handle and OCI_BIND_MAX items in the returning clause
* Fixed Unicode support for Unixes platforms
* Unicode support for platforms with 4 bytes wchar_t was broken
* Fixed configure script was setting bad charset macros
* Fixed some internal buffer expansion functions
* Miscellaneous public modifications
- Added OCI_IsNull2()
- Added OCI_ResultsetGetStatement()
- Added OCI_BindArrayOfColls()
- Added functions to retrieve OCI_Schema object from various OCILIB object bases on Oracle object type :
* Added OCI_ObjectGetSchema()
* Added OCI_CollGetSchema()
* Added OCI_RefGetSchema()
- Added runtime information about OCILIB builds modes :
* Added OCI_GetImportMode()
* Added OCI_GetCharsetMetaData()
* Added OCI_GetCharsetUserData()
- On Oracle versions >= 11g, OCILIB now sets the client driver layer name information
* Value set to the constant OCILIB_DRIVER_NAME (by default "OCILIB")
* It's recorded in the system views V$SESSION_CONNECT_INFO and GV$SESSION_CONNECT_INFO
- Modified ocilib demo to properly support MinGw and unix based unicode console output
* Miscellaneous internal modifications
- Added internal reference counter to OCI_Schema object
* Some OCILIB objects keep a pointer to a some OCI_schema objects
* If OCI_SchemaFree() was called, these objects were holding a reference to a freed block of memory and then accessing this reference could cause a segfault
* Now OCI_SchemaFree() only frees an schema object if its reference counter is zero.
* Miscellaneous fixes
- OCI_IsConnected() was always returning FALSE since v3.0.0
- OCI_SchemaGet() with OCI_SCHEMA_TABLE was causing an ORA-24328 with Oracle 8 and 9 (working fine with Oracle 10) since v3.0.0
- Fixed demo file output.c
- Fixed some preprocessor directives in oci_loader.h
- OCI_Fetchxxx() functions could return TRUE even if the given SQL statement had some SQL conversion function that failed (like to_date(), etc..)
- OCI_Getxxx() functions could cause a segfault called before any OCI_Fetchxxx() calls
- Fixed OCI_Object reusability: internal sub object could not be freed when fetching next object and thus lead to memory leaks
- Since v3.0.0, fetching LONG column with OCI_LONG_IMPLICIT mode was truncating data to its half length in Unicode and Mixed Builds
- Fixed some prepocessor directives for MinGw support
- Fixed runtime loading of oracle libs that might have not worked if the provided OCI library location ended with an existing slash
- Fixed internal OCI_CopyString() that might caused some troubles in unicode builds
- Fixed some internal wrong arrays size used for memmory allocation
