</pre></blockquote><p>
122
This routine can be used to find the number of <a href="../c3ref/bind_blob.html">SQL parameters</a>
123
in a <a href="../c3ref/stmt.html">prepared statement</a>. SQL parameters are tokens of the
124
form "?", "?NNN", ":AAA", "$AAA", or "@AAA" that serve as
125
placeholders for values that are <a href="../c3ref/bind_blob.html">bound</a>
126
to the parameters at a later time.</p>
128
<p>This routine actually returns the index of the largest (rightmost)
129
parameter. For all forms except ?NNN, this will correspond to the
130
number of unique parameters. If parameters of the ?NNN form are used,
131
there may be gaps in the list.</p>
