SQL Server 2005 SP3
نیاز به sql server
public string Content { get; set; }
بنابراین اگر هدف، ثبت اطلاعات در فیلدی از نوع ntext در این بانک اطلاعاتی باشد باید به یکی از دو روش زیر عمل کرد:
[MaxLength] public string Content { get; set; }
[Column(TypeName = "ntext")] public string Text { get; set; }
بنابراین قید MaxLength بر روی خواصی که قرار است حاوی متونی طولانی باشند، میتواند به عنوان یک کار مفید جهت سازگاری با بانکهای مختلف، به شمار آید.
Not many are familiar with this awesome feature of dotnet core. Aspnet
team is actively maintaining a project named JavascriptServices
; Along with other packages, it includes the NodeServices
package. Using this package, one can easily create an instance of node
and execute JavaScript code (function) in the backend. If you think of it right now, you can see that it actually opens up a wide variety of development opportunities. By opportunities, I mean; the ASP.NET core project is trying hard to make its package eco-system (NuGet) rich but while doing it, why not get advantages of other package eco-system as well, right? When I talk about other than nuget package manager, the first name that comes to my mind is Npm
(node package manager). Npm
is the largest package manager out there on this very day and its growing rapidly. By using NodeServices
package, we can now use (not all of the npm
packages but) most of the npm
packages in our backend development. So, let me show you how to configure NodeServices
in your aspnet core project and use it to execute JavaScript code on the backend.

ممکن است هنگام تلاش جهت اتصال به دیتابیس اس کیوال سرور 2005 به بعد از طریق management studio با پیغام خطای زیر مواجه شوید:
The database XYZ is not accessible. (ObjectExplorer)
و یا اگر بر روی همین دیتابیس کلیک راست کرده و به خواص آن مراجعه کنیم، خطای 952 زیر صادر شود:
Database 'XYZ' is in transition. Try the statement later. (Microsoft SQL Server, Error: 952)
اصلا نگران نباشید؛ هیچ مشکلی نیست!
ابتدا رویهی ذخیره شدهی sp_who2 را اجرا کنید. یک لیست از کانکشنهای باز به دیتابیسهای موجود را به شما خواهد داد.
در این لیست به دنبال کانکشنهای موجود به دیتابیسی که این خطا را میدهد بگردید. Pid این کانکشنها را یافته و سپس با دستور kill pid آنها را از بین ببرید. مشکل حل خواهد شد.
عموما نبستن خود management studio سبب این مشکل میشود. بنابراین حتی یکبار باز و بسته کردن آن نیز باید این مشکل را برطرف کند (یا تمام management studio های متصل، که البته راه سادهتر همان kill کردن pid آنها است).
