# db2_fetch_row

(PECL)

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

## Descrição

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.

## Parâmetros

`stmt`

  A valid `stmt` resource.

`row_number`

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

## Valores de retornado

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

## Exemplos

Exemplo 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"; } ?>`

Exemplo 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().
`<?php $conn = db2_connect("","",""); $sql = 'SELECT SPECIFIC_SCHEMA, SPECIFIC_NAME, ROUTINE_SCHEMA, ROUTINE_NAME, ROUTINE_TYPE, ROUTINE_CREATED, ROUTINE_BODY, IN_PARMS, OUT_PARMS, INOUT_PARMS, PARAMETER_STYLE, EXTERNAL_NAME, EXTERNAL_LANGUAGE FROM QSYS2.SYSROUTINES FETCH FIRST 2 ROWS ONLY'; $stmt = db2_exec($conn, $sql, array('cursor' => DB2_SCROLLABLE)); while ($row = db2_fetch_both($stmt)){ echo "<br>db2_fetch_both {$row['SPECIFIC_NAME']} {$row['ROUTINE_CREATED']} {$row[5]}"; } $stmt = db2_exec($conn, $sql, array('cursor' => DB2_SCROLLABLE)); while ($row = db2_fetch_array($stmt)){ echo "<br>db2_fetch_array {$row[1]} {$row[5]}"; } $stmt = db2_exec($conn, $sql, array('cursor' => DB2_SCROLLABLE)); while ($row = db2_fetch_object($stmt)){ echo "<br>db2_fetch_object {$row->SPECIFIC_NAME} {$row->ROUTINE_CREATED}"; } db2_close($conn); ?>`
