<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>.
