++++ Introduction
+Doctrine uses DataDict module internally to convert native RDBMS types to Doctrine types and the reverse. DataDict module uses two methods for the conversions:
+1. getPortableDeclaration(), which is used for converting native RDBMS type declaration to portable Doctrine declaration
+2. getNativeDeclaration(), which is used for converting portable Doctrine declaration to driver specific type declaration
+
+
++++ Getting portable declaration

+
+$decl = $conn->dataDict->getPortableDeclaration('VARCHAR(255)');
+
+print_r($decl);
+/*
