Element 

Type

Description

qry_hndl

resource

A valid query handle

<return>

mixed

Integer on success, False on failure

Semantics

The fbird_num_fields function returns the number of parameter markers (“?”) in the prepared query specified by the query handle. This is the number of binding arguments that must be present when calling fbird_execute.

The function returns False upon failure.

Example

The below example code fragment prepares a query and echoes the number of parameter markers to the browser (“1” in the example):

$sql = "UPDATE table SET field2 = ?";
$qry = fbird_prepare($sql);
echo fbird_num_params($qry);
