db2_fetch_row

说明

Use db2_fetch_row() to iterate through a result set, or to point to a specific row in a result set if you requested a scrollable cursor.

To retrieve individual fields from the result set, call the db2_result() function.

Rather than calling db2_fetch_row() and db2_result(), most applications will call one of db2_fetch_assoc(), db2_fetch_both(), or db2_fetch_array() to advance the result set pointer and return a complete row as an array.

参数

返回值

Returns TRUE if the requested row exists in the result set. Returns FALSE if the requested row does not exist in the result set.

范例

例子 1. Iterating through a result set The following example demonstrates how to iterate through a result set with db2_fetch_row() and retrieve columns from the result set with db2_result(). <?php $sql = 'SELECT name, breed FROM animals WHERE weight < ?'; $stmt = db2_prepare($conn, $sql); db2_execute($stmt, array(10)); while (db2_fetch_row($stmt)) {     $name = db2_result($stmt, 0);     $breed = db2_result($stmt, 1);     print "$name $breed"; } ?> 上例将输出： cat Pook gold fish Bubbles budgerigar Gizmo goat Rickety Ride
