ORACLE编程的好东西,纯C写的OCI封装.很好用,支持数据池.

      - See section in the documentation (page <module>, section <Installation>)
      - Added configure option : --with-oracle-headers-path
      - Added configure option : --with-oracle-lib-path

    * Extended OCILIB documentation:

      - Added "Installation" page
      - All examples have been checked, updated, corrected and extended
      - All examples are now provided as full programs sources code

    * Added more demo source code

      - 26 full application sources codes are now provided in the ocilib/demo directory
      - Theses application examples are now integrated in the OCILIB documentation
 
    * Misc:

      - Added const qualifier to return values of OCI_HandleXXX() calls
      - Fixed parameter checking in some OCI_ObjectXXX() calls

2008-04-24 Version 2.4.0 Vincent Rogier [e-mail]

    * Extended support for handling all integers types

      - Added type big_int (64bits <span class="keywordtype">long</span> <span class="keywordtype">long</span> if supported or <span class="keywordtype">int</span> if 64bits integers not available)

      - Added    : OCI_Initialize() with OCI_CHARSET_UNICODE and Oracle client 8 raises now an error (Oracle 8i cannot handle Unicode metadata strings)
      - Added    : OCI_xxxFmt() calls raise now an error if a format identifier is invalid
      - Added    : OCI_Immediatexxx() calls raise now an error if the type value is not an OCI_ARG_XXX constant
      - Modified : Internal error functions (added OCI_ErrorGeneric())

    * Modified <a class="code" href="group__g__format.html#g85318e359913e49d5654d2f53a070ef7" title="Perform 3 calls (prepare+execute+fetch) in 1 call.">OCI_Immediate</a>() and <a class="code" href="group__g__format.html#g845524c6dce7499a0cc27488052a93c2" title="Performs 4 call (prepare+bind+execute+fetch) in 1 call.">OCI_ImmediateFmt</a>()

      - Extended type safety (public interface modifications) :

        * For output placeholders, you have to pass NOW one of the OCI_ARG_xxx constant to tell OCILIB the type the placeholder pointer
        * Every placeholder pointer has to be preceded by the type constant
        * Example : <a class="code" href="group__g__format.html#g85318e359913e49d5654d2f53a070ef7" title="Perform 3 calls (prepare+execute+fetch) in 1 call.">OCI_Immediate</a>(st, "select int_col, str_col from my_table", OCI_ARG_INT, &amp;my_int, OCI_ARG_TEXT, my_text);
        * Output placeholders : support NOW for <span class="keywordtype">short</span>, <span class="keywordtype">unsigned</span> <span class="keywordtype">short</span>, <span class="keywordtype">unsigned</span> <span class="keywordtype">int</span>, big_int, big_uint
        * Updated section in the documentation (page &lt;module&gt;, section &lt;Formatted functions&gt;)
  
      - Fixed    : For <a class="code" href="group__g__format.html#g845524c6dce7499a0cc27488052a93c2" title="Performs 4 call (prepare+bind+execute+fetch) in 1 call.">OCI_ImmediateFmt</a>(), temporary Statement <span class="keywordtype">object</span> was not freed (line commented in 2.3.0 with no reasons !)
      - Fixed    : If internal <a class="code" href="group__g__fetch.html#g755a9b07c174feacd05c86e0e44b0ab0" title="Return the current string value of the column at the given index in the resultset...">OCI_GetString</a>() returned NULL, a segmentation fault could happen 
      - Modified : No check was done on scalar C type placeholder pointers nullity (possible source of seg fault)
      - Modified : <a class="code" href="struct_o_c_i___date.html" title="Oracle internal date representation.">OCI_Date</a> handling was not updated with v2.3.0 modifications
      - Modified : <a class="code" href="struct_o_c_i___long.html" title="Oracle Long datatype.">OCI_Long</a> and <a class="code" href="struct_o_c_i___statement.html" title="Oracle SQL or PL/SQL statement.">OCI_Statement</a> handling was not removed as stated in the changelog of v2.3.0
      - Modified : Factorization of the 2 functions code
