<a href="intro.html"><h2>SQLite C Interface</h2></a><h2>Name Of A Host Parameter</h2><blockquote><pre>const char *sqlite3_bind_parameter_name(sqlite3_stmt*, int);
</pre></blockquote><p>
The sqlite3_bind_parameter_name(P,N) interface returns
the name of the N-th <a href="../c3ref/bind_blob.html">SQL parameter</a> in the <a href="../c3ref/stmt.html">prepared statement</a> P.
SQL parameters of the form "?NNN" or ":AAA" or "@AAA" or "$AAA"
have a name which is the string "?NNN" or ":AAA" or "@AAA" or "$AAA"
respectively.
In other words, the initial ":" or "$" or "@" or "?"
is included as part of the name.
Parameters of the form "?" without a following integer have no name
and are referred to as "nameless" or "anonymous parameters".</p>
<p>The first host parameter has an index of 1, not 0.</p>
<p>If the value N is out of range or if the N-th parameter is
nameless, then NULL is returned. The returned string is
always in UTF-8 encoding even if the named parameter was
originally specified as UTF-16 in <a href="../c3ref/prepare.html">sqlite3_prepare16()</a> or
<a href="../c3ref/prepare.html">sqlite3_prepare16_v2()</a>.</p>
