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