Parameters in <parameter>parameter_array</parameter> will be
substituted for placeholders in the prepared statement in order.
Elements of this array will be converted to strings by calling this
function.
</para>
<para>
Any parameters in <parameter>parameter_array</parameter> which
start and end with single quotes will be taken as the name of a
file to read and send to the database server as the data for the
appropriate placeholder.
</para>
<simpara>
If you wish to store a string which actually begins and ends with
single quotes, you must add a space or other non-single-quote character
to the beginning or end of the parameter, which will prevent the
parameter from being taken as a file name. If this is not an option,
then you must use another mechanism to store the string, such as
executing the query directly with <function>odbc_exec</function>).

$a = 1;
$b = 2;
$c = 3;
$stmt = odbc_prepare($conn, 'CALL myproc(?,?,?)');
$success = odbc_execute($stmt, array($a, $b, $c));
?>
]]>
</programlisting>
</example>
</para>
<para>
If you need to call a stored procedure using INOUT or OUT parameters,
the recommended workaround is to use a native extension for your database
(for example, <link linkend='ref.mssql'>mssql</link> for MS SQL Server,
or <link linkend='ref.mssql'>oci8</link> for Oracle).
