oci的源码,可以在任何平台上编译,相当方便实用

      - Fixed <a class="code" href="group__g__long.html#gd7e0ba53269cc2d5aace557a984c8717" title="Read a portion of a long into the given buffer [Obsolete].">OCI_LongRead</a>() : internal offset variable was not reset across <a class="code" href="group__g__fetch.html#g36ac26dcea78f6074421781e401f97ba" title="Fetch the next row of the resultset.">OCI_FetchNext</a>() calls causing NULL reads after some fetch sequences
      - Fixed memory leak in internal function OCI_ObjectInit()
      - Fixed configure script for GNU package to detect OCI header location of some older versions ($ORACLE_HOME/rdbms/demo)
      - Fixed internal OCI_StringCopy2to4bytes() when converting internal Oracle UTF16 strings with odd lengths to Unix UTF32 strings
      - Renamed OCI_ColumnGetFractionnalPrecision() to <a class="code" href="group__g__fetch.html#g2b6cb330cfc05cb6510917563698de62" title="Return the fractional precision of the column for timestamp and interval columns...">OCI_ColumnGetFractionalPrecision</a>() - added macro for backward compatibility
      
    * Updated windows package

      - Added 2 code::blocks projects
         - ocilib_static_lib_mingw.cbp : to build OCILIB as a 32 bits static library (ansi, mixed and unicode builds) in ocilib/proj/mingw
         - ocilib_demo_codeblocks.cbp  : to build OCILIB 32 bits demo application (ansi, mixed and Unicode builds) in ocilib/proj/test
      - Precompiled OCILIB 32 bits static libraries are now provided within the package :
         - built with Code::Block 8.03 (minGW / gcc-core-3.4.5)
         - available static libs in ocilib/lib32 : libociliba.a (ansi), libocilibm.a (mixed), libocilibw.a (unicode)
      - OCILIB prebuilt Dlls are still compiled with Microsoft Visual Studio
      
    * Miscellaneous internal changes

      - The <span class="keywordtype">object</span> cache is now freed when a connection is terminated
      - Internal source file schema.c has been renamed to typeinfo.c
      - Internal source file dirpath.c has been added
      - Fixed some internal calls to please GDCC and its aliasing warnings with -Wall options
      
    * Documentation updates 

      - Added notes in <a class="code" href="group__g__connect.html#gdb6e2cdf759587dd81c2fda7c5f44338" title="Create a physical connection to an Oracle database server.">OCI_ConnectionCreate</a>() documentation for using External credentials
      - Added notes in <a class="code" href="group__g__bind.html#g60d87fbeb94afeaf410ec243eb8c0f98" title="Set the input array size for bulk operations.">OCI_BindArraySetSize</a>() documentation for modifying input array number of elements between statement executions
      - All OCILIB headers and sources files (45 files - 43.000 lines) have been checked with spell checker to correct typos (my English remains not so good !)
