datatypes through scalar C datatypes</li><li>Oracle opaque/complex objects though opaque library handles</li><li>Library objects for manipulating the database: connections, transactions, statements...</li></ul><p><dl class="user" compact><dt><b>Supported Oracle datatypes</b></dt><dd></dd></dl><ul><li>All Database types are supported excluding REFs.</li></ul><p>Here is a summary of the supported datatypes:<p><ul><li>Scalar types CHAR/NCHAR, VARCHAR2/NVARCHAR2, NUMBER, FLOAT, REAL, RAW, ...</li><li>Binary types: RAW, LONG RAW, VARRAW, ..</li><li>Larges Objects (Lobs and Files) : BLOB, CLOB, NCLOB, BFILE</li><li>LONG types: LONG, VAR LONG</li><li>Date, Timestamps et Intervals: DATE, TIMESTAMP, INTERVAL</li><li>PL/SQL types: Ref cursors, PL/SQL Tables</li><li>Named Types (by value): Builtin system objects and User defined objects</li><li>VARRAYs and Nested Tables</li><li>ROWIDs</li></ul><p><dl class="user" compact><dt><b>OCILIB library objects</b></dt><dd></dd></dl>The public OCILIB library interface implements encapsulation for representing database objects (such as connections, statements, ...) through opaque structures (pointers to structures whose definition is kept private)<p>Instead of directly manipulating the structures and their members, the library has functions to access the underlying members.<p>It's designed to make the user code as more independant as possible of the library details. <p><table border="0" cellpadding="0" cellspacing="0"><tr><td></td></tr><tr><td colspan="2"><br><h2>Data Structures</h2></td></tr><tr><td class="memItemLeft" nowrap
