Good day, and welcome to the TechNet wiki summit 2015.

This is how I opened my lecture yesterday…

This simple sentence is very meaningful! It hides so much in two words. Usually when I start a lecture I open with “Good morning” or Good evening” or something that make sense to the current audience at the current time in the current place. In this case, our event appeals to variety audience which engage with variety technologies, from all over the world in different time-zones.  In my opinion this is the main feature of the TechNet WIKI summit.

In some case we have to use single value, in order to represent a list of elements (values). This is a very common needs in hardware and software developing. All the logics that we discus in this article, can be implements regardless of database use. In this article we will focus on using SQL Server to implement our logics. This might be an external demand (applications for example) or even a result of bad database design. Yet, the needs is clear, we want to store multiple elements in one column. Those elements can be properties list, options, security permissions, dates, or any other data.

In this article we will go over several solutions, using different logics. Our challenge is to find a good logic, which give us a one-to-one correspondence, between each available combination of our elements, to a single value which represent this combination.

Sometimes A new version or feature release and a new bug which related to this feature revealed, but sometimes we stuck with a BUG for years.. many years... 15 years even... will it be fix in the next version?

Using User Defined Function In Constraint can lead to a BUG! In this short blog I will just reproduce the BUG and show a simple workaround. This is not a new topic, and you probably can find lot of articles on net,on the same issue, but since it came up again... i decided to post this blog again.

Short and simple Stored Procedure to find the pearson who was the last one who deleted a record from a table. Very useful when your boss delete row and start to shout at you why the data is not accurate, or why tour application have a bug :-)

This is small set of script in order to get the connection properties. You can use it in order to compare two execution of the same query on the same database which use different Execution Plan as a result of different Connection Properties.

This short blog give a simple example how to use "FOR XML" hint in order to consolidate data in different rows into a single row in the result SET (an operation known as Un-Split data). In this example we are going to group together only rows with the same value in specific column/s. In short we can call this action "Un-split data with grouping"

SQL Server can listen to request which come to specific IP address on specific port, or to all request regardless the IP, It can listen to request which come to a Named pipe, as well. By default, SQL server uses port 1433 in TCP/IP, and default instance of Microsoft SQL Server listens on "\\.\pipe\sql\query" named pipe.

In this short article I will show how we can configure those options.
