<simpara>
<function>dbx_fetch_row</function> returns a row on success, and
<literal>0</literal> on failure (e.g. when no more rows are available).
When the <constant>DBX_RESULT_UNBUFFERED</constant> is not set in the
query, <function>dbx_fetch_row</function> will fail as all rows have
already been fetched into the results <property>data</property> property.
</simpara>
<simpara>
As a side effect, the <property>rows</property> property of the query-result
object is incremented for each successful call to
<function>dbx_fetch_row</function>.
</simpara>

<para>
The <parameter>result_identifier</parameter> parameter is the result
object returned by a call to <function>dbx_query</function>.
</para>
<para>
The returned object contains the same information as any row would have
in the dbx_query result <property>data</property> property, including
columns accessible by index or fieldname when the flags for dbx_guery
were set that way.
