<a href="intro.html"><h2>SQLite C Interface</h2></a>
<h2>Prepared Statement Object</h2>
</div>
<blockquote><pre>
typedef struct sqlite3_stmt sqlite3_stmt;
</pre></blockquote>
<p>
An instance of this object represents a single SQL statement that
has been compiled into binary form and is ready to be evaluated.</p>
<p>Think of each SQL statement as a separate computer program. The
original SQL text is source code. A prepared statement object
is the compiled object code. All SQL must be converted into a
prepared statement before it can be run.</p>
<p>The life-cycle of a prepared statement object usually goes like this:</p>
<p><ol>
<li> Create the prepared statement object using <a href="../c3ref/prepare.html">sqlite3_prepare_v2()</a>.
<li> Bind values to <a href="../lang_expr.html#varparam">parameters</a> using the sqlite3_bind_*()
interfaces.
<li> Run the SQL by calling <a href="../c3ref/step.html">sqlite3_step()</a> one or more times.
<li> Reset the prepared statement using <a href="../c3ref/reset.html">sqlite3_reset()</a> then go back
to step 2. Do this zero or more times.
<li> Destroy the object using <a href="../c3ref/finalize.html">sqlite3_finalize()</a>.
</ol>
