+<h2>Column Names In A Result Set</h2>
+</div>
+<blockquote><pre>
+const char *sqlite3_column_name(sqlite3_stmt*, int N);
+const void *sqlite3_column_name16(sqlite3_stmt*, int N);
+</pre></blockquote>
+<p>
+These routines return the name assigned to a particular column
+in the result set of a <a href="../lang_select.html">SELECT</a> statement. The sqlite3_column_name()
+interface returns a pointer to a zero-terminated UTF-8 string
+and sqlite3_column_name16() returns a pointer to a zero-terminated
+UTF-16 string. The first parameter is the <a href="../c3ref/stmt.html">prepared statement</a>
+that implements the <a href="../lang_select.html">SELECT</a> statement. The second parameter is the
+column number. The leftmost column is number 0.</p>
+
+<p>The returned string pointer is valid until either the <a href="../c3ref/stmt.html">prepared statement</a>
+is destroyed by <a href="../c3ref/finalize.html">sqlite3_finalize()</a> or until the statement is automatically
+reprepared by the first call to <a href="../c3ref/step.html">sqlite3_step()</a> for a particular run
+or until the next call to
+sqlite3_column_name() or sqlite3_column_name16() on the same column.</p>
+
+<p>If sqlite3_malloc() fails during the processing of either routine
+(for example during a conversion from UTF-8 to UTF-16) then a
+NULL pointer is returned.</p>
+
+<p>The name of a result column is the value of the "AS" clause for
+that column, if there is an AS clause. If there is no AS clause
+then the name of the column is unspecified and may change from
+one release of SQLite to the next.
