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>
In PHP 5.0.0 and up, this function will return the number of rows
affected by the query for INSERT, UPDATE and DELETE statements. In order
to retain backward compatibility, it will return &true; for these
statements if the query succeeded without affecting any rows.

If you get some error like "arithmetic exception, numeric overflow, or
string truncation. Cannot transliterate character between character sets"
(this occurs when you try use some character with accents) when using this
and after <function>ibase_query</function> you must set the character set
(i.e. ISO8859_1 or your current character set).
