在sfs 2x執行SQL語法
是透過IDBManager物件來處理
如果要傳入參數給SQL語法的話
要用PreparedStatement物件來處理
取出陣列，直接傳給Client

IDBManager dbManager = getParentExtension().getParentZone().getDBManager(); String sql = "SELECT * FROM people";

response.putSFSArray("people", res);
send("getPeople", response, sender);
} catch (SQLException e)
{ trace(ExtensionLogLevel.WARN, "SQL Failed: " + e.toString());
