• هرگاه در اجرای Count ،هدفتان بدست آوردن تعداد ستون خاصی است، از (Count(column استفاده نمایید.

• روش اول 

(a+b)+ABS(a-b)

0.5(a+b)+ABS(a-b)

DECLARE @Value1 DECIMAL(5,2) = 80.22
DECLARE @Value2 DECIMAL(5,2) =90.34
SELECT (0.5 * ((@Value1 + @Value2) + ABS(@Value1 - @Value2))) AS MaxColumn  

• روش دوم

در این روش اگر مقدار یکی از اعداد Null باشد،ماکزیمم بین دو عدد، عدد غیر Null می‌باشد.

5- مشاهده مشخصات کلیه دیتابیس‌های موجود در SQL Server با استفاده از Sys.Databases .

Select * From sys.databases

خروجی بصورت زیر خواهد بود:

6- بوسیله دستور OUTPUT می‌توان خروجی Query‌های Delete،Update و Insert را مشاهده نمود:

مثال اول برای Query Delete :

در شکل، تک رکورد حذف شده را مشاهده می‌نمایید.

مثال دوم برای Query Update بصورت زیر میباشد:

در شکل، مقدار A، مقدار جدیدی است که بروز رسانی شده است و مقدار B مقداری است که مربوط به قبل از بروز رسانی می‌باشد.

مثال سوم برای Query Insert بصورت زیر میباشد:

موفق باشید.
