TSQL Technique for attribute evaluation


TSQL Technique for attribute evaluation

I think the issue was by ths following , I have a table with 20 columns. The first is my primary key. The remaining columns are attributes about the primary key. I need to evaluate each column on a row by row basis. If a attribute column has a value other than null, then do some further processing. , You could unpivot the table and filter out things that are not NULL:
code :
select pk, col, val
from (select pk, col, val
      from table t
      unpivot (val for col in (attr1, attr2, . . . )) as unpivot
     ) u
where val is not null;

Does that help You can't rely on SQL Server not evaluating the second expression if the first one is false. See my answer to the question linked by Martin in his comment.

wish of those help Although you can use where 1 = 0 for this purpose, I think top 0 is more common:
code :
select top 0 . . . 
. . .
where condition x or condition y
where 1 = 0 and condition x or condition y

wish help you to fix your issue Best is to solve this issue directly in the back end, as it is discouraged by search engines to use JavaScript to form you structured data.
Although Google is more and more implementing ways to dynamically (thus with JavaScript) crawl through your site, I advice you to take the safe road and fix this within your back end logic.

like below fixes the issue
Create a synthetic data set with known edges, for example by 3D rendering, by compositing 2D images with precise masks (as may be obtained in royalty free photosets), or by introducing edges directly (thin/faint lines). Remember to add some confounding non-edges that look like edges, of a type appropriate for what you're tuning for.
