db2_fetch_assoc

(PECL)

db2_fetch_assoc -- Returns an array, indexed by column name, representing a row in a result set

Popis

array db2_fetch_assoc ( resource stmt [, int row_number] )

Returns an array, indexed by column name, representing a row in a result set.

Seznam parametrů

stmt: A valid stmt resource containing a result set.
row_number: Requests a specific 1-indexed row from the result set. Passing this parameter results in a PHP warning if the result set uses a forward-only cursor.

Návratové hodnoty

Returns an associative array with column values indexed by the column name representing the next or requested row in the result set. Returns FALSE if there are no rows left in the result set, or if the row requested by row_number does not exist in the result set.

Příklady

Příklad 1. Iterating through a forward-only cursor

If you call db2_fetch_assoc() without a specific row number, it automatically retrieves the next row in the result set.


<?php

$sql = "SELECT id, name, breed, weight FROM animals ORDER BY breed";
$stmt = db2_prepare($conn, $sql);
$result = db2_execute($stmt);

while ($row = db2_fetch_assoc($stmt)) {
    printf ("%-5d %-16s %-32s %10s\n", 
        $row['ID'], $row['NAME'], $row['BREED'], $row['WEIGHT']);
}
?>

Výše uvedený příklad vypíše:

0     Pook             cat                                    3.20
5     Rickety Ride     goat                                   9.70
2     Smarty           horse                                350.00

Příklad 2. Retrieving specific rows with db2_fetch_assoc() from a scrollable cursor

If your result set uses a scrollable cursor, you can call db2_fetch_assoc() with a specific row number. The following example retrieves every other row in the result set, starting with the second row.


<?php

$sql = "SELECT id, name, breed, weight FROM animals ORDER BY breed";
$result = db2_exec($stmt, $sql, array('cursor' => DB2_SCROLLABLE));

$i=2;
while ($row = db2_fetch_assoc($result, $i)) {
    printf ("%-5d %-16s %-32s %10s\n", 
        $row['ID'], $row['NAME'], $row['BREED'], $row['WEIGHT']);
    $i = $i + 2;
}
?>

Výše uvedený příklad vypíše:

0     Pook             cat                                    3.20
5     Rickety Ride     goat                                   9.70
2     Smarty           horse                                350.00
