PHP-Handbuch: Makes the next row in a result set available for reading

Beschreibung

mixed sqlsrv_fetch ( resource $stmt [, int $row [, int $offset ]] )

Makes the next row in a result set available for reading. Use sqlsrv_get_field to read the fields of the row.

Parameter-Liste

stmt

A statement resource created by executing sqlsrv_query or sqlsrv_execute.

row

The row to be accessed. This parameter can only be used if the specified statement was prepared with a scrollable cursor. In that case, this parameter can take on one of the following values:

SQLSRV_SCROLL_NEXT
SQLSRV_SCROLL_PRIOR
SQLSRV_SCROLL_FIRST
SQLSRV_SCROLL_LAST
SQLSRV_SCROLL_ABSOLUTE
SQLSRV_SCROLL_RELATIVE

offset

Specifies the row to be accessed if the row parameter is set to SQLSRV_SCROLL_ABSOLUTE or SQLSRV_SCROLL_RELATIVE. Note that the first row in a result set has index 0.

Rückgabewerte

Returns TRUE if the next row of a result set was successfully retrieved, FALSE if an error occurs, and NULL if there are no more rows in the result set.

Beispiele

Beispiel #1 sqlsrv_fetch example

The following example demonstrates how to retrieve a row with sqlsrv_fetch and get the row fields with sqlsrv_get_field.


<?php
$serverName = "serverName\sqlexpress";
$connectionInfo = array( "Database"=>"dbName", "UID"=>"username", "PWD"=>"password");
$conn = sqlsrv_connect( $serverName, $connectionInfo);
if( $conn === false ) {
     die( print_r( sqlsrv_errors(), true));
}

$sql = "SELECT Name, Comment 
        FROM Table_1
        WHERE ReviewID=1";
$stmt = sqlsrv_query( $conn, $sql);
if( $stmt === false ) {
     die( print_r( sqlsrv_errors(), true));
}

// Make the first (and in this case, only) row of the result set available for reading.
if( sqlsrv_fetch( $stmt ) === false) {
     die( print_r( sqlsrv_errors(), true));
}

// Get the row fields. Field indeces start at 0 and must be retrieved in order.
// Retrieving row fields by name is not supported by sqlsrv_get_field.
$name = sqlsrv_get_field( $stmt, 0);
echo "$name: ";

$comment = sqlsrv_get_field( $stmt, 1);
echo $comment;
?>
