db2_fetch_both

(PECL ibm_db2 >= 1.0.0)

db2_fetch_both — Returns an array, indexed by both column name and position, representing a row in a result set

설명

array db2_fetch_both ( resource $stmt [, int $row_number = -1 ] )

Returns an array, indexed by both column name and position, representing a row in a result set. Note that the row returned by db2_fetch_both() requires more memory than the single-indexed arrays returned by db2_fetch_assoc() or db2_fetch_array().

인수

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.

반환값

Returns an associative array with column values indexed by both the column name and 0-indexed column number. The array represents 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.

예제

Example #1 Iterating through a forward-only cursor

If you call db2_fetch_both() without a specific row number, it automatically retrieves the next row in the result set. The following example accesses columns in the returned array by both column name and by numeric index.


<?php

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

while ($row = db2_fetch_both($stmt)) {
    printf ("%-5d %-16s %-32s %10s\n", 
        $row['ID'], $row[0], $row['BREED'], $row[3]);
}
?>

Example #2 Retrieving specific rows with db2_fetch_both() from a scrollable cursor

If your result set uses a scrollable cursor, you can call db2_fetch_both() 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_both($result, $i)) {
    printf ("%-5d %-16s %-32s %10s\n", 
        $row[0], $row['NAME'], $row[2], $row['WEIGHT']);
    $i = $i + 2;
}
?>
