سلام به دوستان خوبم
نکته💡💡💡
در پروژه های هوش تجاری بخصوص پروژههای بزرگ، زمانی که چند نفر همزمان بر روی انبار داده مشغول به کار هستند، ممکن است اثر تغییر دستورات DDL همکارتون بر کار شما اثر بذاره برای مثال شما یک ویو با ساختار قبلی داشته اید و اکنون ویو شما دچار مشکل شده.
قطعا برای اکثرتون پیش اومده، ابتدای روز که میرید شرکت میبینید به روز رسانی انبار داده با خطا مواجه شده و پیدا کردن مشکل و رفعش و لود دوباره داده در طول روز مدت زمان زیادی رو از شما خواهد گرفت.
راه حل چیست❓
راه حل پیشنهادی من استفاده از schema binding در اسکریپت تون هست.
در واقع با استفاده از این دستور، هر زمان تغییری در انبار داده بخواهید ایجاد کنید که View یاStore procedure همراه با schema binding را دچار خطا کند، شما با ارور مواجه خواهید شد.
CREATE VIEW

Telegram Q&A

Q: How does hottg.com work?

Once you've set up a username, you can give people a hottg.com/username link. Opening that link on their phone will automatically fire up their Telegram app and open a chat with you. You can share username links with friends, write them on business cards or put them up on your website.This way people can contact you on Telegram without knowing your phone number.

With Telegram, you can send messages, photos, videos and files of any type (doc, zip, mp3, etc), as well as create groups for up to 200,000 people or channels for broadcasting to unlimited audiences. You can write to your phone contacts and find people by their usernames. As a result, Telegram is like SMS and email combined — and can take care of all your personal or business messaging needs. In addition to this, we support end-to-end encrypted voice calls.

Q: What is Telegram? What do I do here?

Telegram is a messaging app with a focus on speed and security, it’s super-fast, simple and free. You can use Telegram on all your devices at the same time — your messages sync seamlessly across any number of your phones, tablets or computers.
