<para>
Execute a query prepared by <function>ibase_prepare</function>. If
the query raises an error, returns &false;. If it is successful and
there is a (possibly empty) result set (such as with a SELECT query),
returns a result identifier. If the query was successful and there were
no results, returns &true;.
</para>
<para>
This is a lot more effective than using <function>ibase_query</function>
if you are repeating a same kind of query several times with only
some parameters changing.

<note>
<para>
In PHP 5.0.0 and up, this function returns the number of rows affected by
the query (if > 0 and applicable to the statement type). A query that succeeded,
but did not affect any rows (e.g. an UPDATE of a non-existent record) will return
&true;.
