ASP.net VB.net SQL - query issue

Hi

I have a GridView on my ASP.net web form  with the SQL table shown in the following image bound to it. I need to get the data into the format in the second image. What SQL or technique would I use to do this. The second image doesn't show the X values but I plan to show them there:

In SQL that would be termed a "pivot", and it can be achieved using SQL

Is the number of columns always the same?
or are you expecting the number of columns to increase/decrease?

This leads to a need to what is known as "dynamic sql"
essentially it is a query that concatenates information together, and the information happens to be the next sql statement.

you then execute that "dynamically generated" sql statement

if you search here at EE for "dynamic pivot tsql" you will see many Questions and Answers on that topic, if you would like to see some example.

What I would suggest now is  that you prepare a new question.
Identify the tables and fields involved
provide some sample data (is a reusbale format, not an image)
and an expected result
specify that the number of columns has to be 'dynamic'

perhaps title the question as:

Need help with dynamic pivot in TSQL


one last thing.
the term "pivot" is generic
but there is also a "pivot" feature in TSQL, however you do not have to use that feature to achieve the result. sometimes using case expressions and group by is just as easy - or even easier.

Hope this helps.
