dbx_fetch

Description

mixed dbx_fetch_row ( object result_identifier )

dbx_fetch_row() returns a row on success, and 0 on failure (e.g. when no more rows are available). When the DBX_RESULT_UNBUFFERED is not set in the query, dbx_fetch_row() will fail as all rows have already been fetched into the results data property.

As a side effect, the rows property of the query-result object is incremented for each successful call to dbx_fetch_row().

例子 1. How to handle the returned value


<?php
$result = dbx_query($link, 'SELECT id, parentid, description FROM table', DBX_RESULT_UNBUFFERED);

echo "<table>\n";
while ($row = dbx_fetch_row($result)) {
    echo "<tr>\n";
    foreach ($row as $field) {
        echo "<td>$field</td>";
    }
    echo "</tr>\n";
}
echo "</table>\n";
?>

The result_identifier parameter is the result object returned by a call to dbx_query().

The returned object contains the same information as any row would have in the dbx_query result data property, including columns accessible by index or fieldname when the flags for dbx_guery were set that way.

Use this function ONLY if you are using:

DBX_RESULT_UNBUFFERED



and make sure the database you're using will allow DBX_RESULT_UNBUFFERED as a flag on the connect line. 



I spent 2 days trying to figure out WHY I couldn't use the dbx_fetch_row() function.  Too many languages!
