范例
示例 #1 sqlsrv_next_result() example
The following example executes a batch query that inserts into a table and then selects from the table. This produces two results on the statement: one for the rows affected by the INSERT and one for the rows returned by the SELECT. To get to the rows returned by the SELECT, sqlsrv_next_result() must be called to move past the first result.
<?php
$serverName = "serverName\sqlexpress";
$connectionInfo = array("Database"=>"dbName", "UID"=>"userName", "PWD"=>"password");
$conn = sqlsrv_connect( $serverName, $connectionInfo);
$query = "INSERT INTO Table_1 (id, data) VALUES (?,?); SELECT * FROM TABLE_1;";
$params = array(1, "some data");
$stmt = sqlsrv_query($conn, $query, $params);
// Consume the first result (rows affected by INSERT) without calling sqlsrv_next_result.
echo "Rows affected: ".sqlsrv_rows_affected($stmt)."<br />";
// Move to the next result and display results.
$next_result = sqlsrv_next_result($stmt);
if( $next_result ) {
while( $row = sqlsrv_fetch_array( $stmt, SQLSRV_FETCH_ASSOC)){
echo $row['id'].": ".$row['data']."<br />";
}
} elseif( is_null($next_result)) {
echo "No more results.<br />";
} else {
die(print_r(sqlsrv_errors(), true));
}
?>

You can use a for loop to iterate through the results:
If you know how many results there should be it's easier, otherwise you can put a large number in the loop constructor and break when done:
<?
for ($i=0; $i< (Large # or Exact #); $i++)
{
$rows_affected = sqlsrv_rows_affected($q2);
if ($rows_affected === false)
{
echo 'Inserts Failed<br />\n';
} else if ( $rows_affected == -1) {
echo "No information available.<br />\n";
} else {
echo $rows_affected." rows were added.<br />\n";
}
$next_result = sqlsrv_next_result($q2);
if (!$next_result)
{
break;
}
}
?>
