SQL SERVER – How to Connect Using NT AUTHORITY \ SYSTEM Account?

Pinal Dave

SQL Tips and Tricks

Command Line, SQL Server, SQL Server Security

Sometimes it is needed to connect to SQL Server using System account. Don’t literally ask me if this is a valid scenario in first place. Someone just pinged to say – they want to do it. I was personally not sure why, but they had their own internal requirement to do the same. Let us learn about in this blog post about how to connect using NT AUTHORITY \ SYSTEM Account?

It is not possible to provide windows credential in SSMS and they are always grayed out. My exploration is always to keep trying to find a solution to such typical use cases. I was able to find that PSExec can be used to achieve this. I am a big fan of some of the tools from sysinternals. These are handy and quite small footprint of the servers. One of the tools I have day-in day-out is ZoomIt while doing presentations.

Interview Question of the Week #057 – What is GO Statement in SQL SERVER?

Pinal Dave

SQL Interview Questions and Answers

SQL Scripts, SQL Server

GO is not a Transact-SQL statement; it is often used in T-SQL code. Go causes all statements from the beginning of the script or the last GO statement (whichever is closer) to be compiled into one execution plan and sent to the server independent of any other batches. SQL Server utilities interpret GO as a signal that they should send the current batch of Transact-SQL statements to an instance of SQL Server. The current batch of statements is composed of all statements entered since the last GO, or since the start of the ad hoc session or script if this is the first GO.

SQL Tips and Tricks

SQL Error Messages, SQL Server

Doing repetitive tasks is something everyone hates. I am sure many of us have resorted to ingenious techniques to figure out doing the task efficiently. There is no standard tool or technique that everyone uses. Recently I was asked to install a SQL instance with same configuration on 10 servers. Who would like to log in to all those servers, run setup.exe and go through the same setup wizard? Luckily, the SQL Server setup allows to create a configuration file. The very thought of extracting it as configuration is something that made me jump out of my seat. Let us learn about Install Error – The /UIMode setting cannot be used in conjunction with /Q or /QS.

SQL Performance

In-Memory OLTP, SQL Scripts, SQL Server

InMemory is an awesome concept and I have been fortunate to learn about the same from my friends in the industry over blogs. It holds deep concepts and is sometimes tough to understand how the building blocks come together. I am not the only one doing the exploration, but a number of you also do and pass those learnings to me via your interesting questions. Thanks to each one of you who take a moment to ask me some of these questions that shake the fundamentals and make my understanding stronger. In the same lines, one of the readers wrote back to me after reading the MSDN on InMemory OLTP, what does the concepts of Optimistic multi-version concurrency really mean. On first thought, it looks simple, but the question was very loaded.

SSMS is a nice tool for database developers. However, it is far from being ideal, and this is because some routine operations in SSMS are extremely inconvenient to perform. Let us learn about dbForge Object Search for SQL Server.

Very often, developers face the challenge of searching a database for all occurrences of an object, column, variable, or search simultaneously all the objects, in which a search value occurs. If you happen to solve a similar problem, then you must know that this problem is not the most trivial and Ctrl + F will not help here.
