Примеры

Пример #1 sqlsrv_query() example
$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 = "INSERT INTO Table_1 (id, data) VALUES (?, ?)";
$params = array(1, "some data");
$stmt = sqlsrv_query( $conn, $sql, $params);
if( $stmt === false ) {
     die( print_r( sqlsrv_errors(), true));
}


Примечания

For statements that you plan to execute only once, use sqlsrv_query(). If you intend to re-execute a statement with different parameter values, use the combination of sqlsrv_prepare() and sqlsrv_execute().
