Purpose

This document outlines why the optimization of queries containing bind variables may be deferred until execution time. Remember that that a SQL statement submitted while CURSOR_SHARING is set to 'FORCE' will, in effect, become a statement with system-generated bind variables.  For information about the sharing of cursors, refer to :

Oracle Database Online Documentation 12c Release 1 (12.1)
Database SQL Tuning Guide
Chapter 15 Controlling Cursor Sharing
