db2_fetch_row Sets the result set pointer to the next row or requested row


bool db2_fetch_row ( resource $stmt [, int $row_number ] )

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.

Список параметров


A valid stmt resource.


With scrollable cursors, you can request a specific row number in the result set. Row numbering is 1-indexed.

Возвращаемые значения

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


Пример #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().

'SELECT name, breed FROM animals WHERE weight < ?';
$stmt db2_prepare($conn$sql);
db2_execute($stmt, array(10));
while (
db2_fetch_row($stmt)) {
$name db2_result($stmt0);
$breed db2_result($stmt1);
"$name $breed";

Пример #2 i5/OS recommended alternatives to db2_fetch_row/db2_result

On i5/OS it is recommended that you use db2_fetch_both(), db2_fetch_array(), or db2_fetch_object() over db2_fetch_row()/db2_result(). In general db2_fetch_row()/db2_result() have more issues with various column types in EBCIDIC to ASCII translation, including possible truncation in DBCS applications. You may also find the performance of db2_fetch_both(), db2_fetch_array(), and db2_fetch_object() to be superior to db2_fetch_row()/db2_result().

$stmt db2_exec($conn$sql, array('cursor' => DB2_SCROLLABLE));
  while (
$row db2_fetch_both($stmt)){
"<br>db2_fetch_both {$row['SPECIFIC_NAME']} {$row['ROUTINE_CREATED']} {$row[5]}";
$stmt db2_exec($conn$sql, array('cursor' => DB2_SCROLLABLE));
  while (
$row db2_fetch_array($stmt)){
"<br>db2_fetch_array {$row[1]}  {$row[5]}";
$stmt db2_exec($conn$sql, array('cursor' => DB2_SCROLLABLE));
  while (
$row db2_fetch_object($stmt)){
"<br>db2_fetch_object {$row->SPECIFIC_NAME} {$row->ROUTINE_CREATED}";
