Repeat Hire Rate

In The Top 3% Freelancers. SQL Server Consultant.

Top-rated elite freelancer, specialized in Microsoft SQL Server on-premises or in the cloud. If you hire me for remote consultation: 1 of 3 things will happen from this consultation... 1) You will find that my consultation is not for you and that's OKAY - but you might think of someone you know that I can help. 2) You will get results from the consultation which helps your current situation - but you don't need any more and that's OKAY too. 3) You will get so much from this one consultation that you would like to explore how longer term consultation can have a positive impact on your life and business and we can agree on a way forward and that's OKAY too. This is remarkable: "It's hard to make our server 100x faster - but it's really easy to make our database design and queries suddenly 100x more efficient. Fixing queries and tables and indexes is indeed hard work - but it's totally worth it."

Does the below SQL code generate an error or run successfully in SQL Server?

IF EXISTS ( SELECT *
FROM Sales.Customers
GROUP BY country )

PRINT 'This works! Thanks Dmitri Korotkevitch for the tip!';

If you got surprised after running the code and thinking "what's wrong with SQL Server". The answer is, it runs successfully due to "unnesting/substitution of table expressions" in SQL Server.

A genius guy Brendan described the speed of a server (Database Server) in terms of human being.

He said- suppose if 1 CPU cycle is of 1 second then Level 1 cache access will take 3 seconds, Level 2 cache access will take 9 seconds, Level 3 cache access will take 43 seconds, Main memory access (RAM) will take 6 minutes, Solid state disk (SSD) I/O will take 2-6 days, Rotational disk I/O will take 1-12 months and so on.

I awarded first project by Tim Austin Mills of SQL Assistance on 09 Sep 2020. Project description looked simple but after understanding requirements completely; It was though.

After working for few hours I ended up with very tricky SQL Script that fulfilled needs completely. I delivered prod ready SQL Script to Tim; In return I got bonus amount, 5 star rating and great review.
