SQLSRV_SCROLL_NEXT,SQLSRV_SCROLL_PRIOR,SQLSRV_SCROLL_FIRST,SQLSRV_SCROLL_LAST,SQLSRV_SCROLL_ABSOLUTEand,SQLSRV_SCROLL_RELATIVE(the default). When this parameter is specified, thefetchTypemust be explicitly defined. -

Примеры
Пример #1 Retrieving an associative array.
<?php
$serverName = "serverName\instanceName";
$connectionInfo = array( "Database"=>"dbName", "UID"=>"username", "PWD"=>"password");
$conn = sqlsrv_connect( $serverName, $connectionInfo );
if( $conn === false ) {
die( print_r( sqlsrv_errors(), true));
}
$sql = "SELECT FirstName, LastName FROM SomeTable";
$stmt = sqlsrv_query( $conn, $sql );
if( $stmt === false) {
die( print_r( sqlsrv_errors(), true) );
}
while( $row = sqlsrv_fetch_array( $stmt, SQLSRV_FETCH_ASSOC) ) {
echo $row['LastName'].", ".$row['FirstName']."<br />";
}
sqlsrv_free_stmt( $stmt);
?>
Пример #2 Retrieving a numeric array.
<?php
$serverName = "serverName\instanceName";
$connectionInfo = array( "Database"=>"dbName", "UID"=>"username", "PWD"=>"password");
$conn = sqlsrv_connect( $serverName, $connectionInfo );
if( $conn === false ) {
die( print_r( sqlsrv_errors(), true));
}
$sql = "SELECT FirstName, LastName FROM SomeTable";
$stmt = sqlsrv_query( $conn, $sql );
if( $stmt === false) {
die( print_r( sqlsrv_errors(), true) );
}
while( $row = sqlsrv_fetch_array( $stmt, SQLSRV_FETCH_NUMERIC) ) {
echo $row[0].", ".$row[1]."<br />";
}
sqlsrv_free_stmt( $stmt);
?>
Примечания
Not specifying the fetchType or explicity using the
SQLSRV_FETCH_TYPE constant in the examples above will
return an array that has both associative and numeric keys.
If more than one column is returned with the same name, the last column will take precedence. To avoid field name collisions, use aliases.
If a column with no name is returned, the associative key for the array element will be an empty string ("").
