It might be easier to skip to the examples.</p> <p>A table has an id and four columns that each allow null. </p> <pre><code>ID, Col1, Col2, Col3, Col4 </code></pre> <p>There are x number of rows. ( Usually less than 4 ) And only up to 4 distinct values will be used across the columns.</p> <p>I am looking to return up to 4 rows, where each row in the resulting set is basically a column value where the value is selected left from right starting at the top preserving Col number. If another row has a value that is not column unique it is shifted to the next available column.</p> <p>Examples:</p> <p>If I have:</p> <pre><code>ID, Col1, Col2, Col3, Col4 0, A , B , , D 1, , , C , </code></pre> <p>I would like to return</p> <pre><code>A B C D </code></pre> <p>and</p> <pre><code>ID, Col1, Col2, Col3, Col4 0, A , B , C , 1, D , , , </code></pre> <p>Gives</p> <pre><code>A B C D </code></pre> <p>Thanks! The scenario when there are non unique columns and spaces between values can be thrown out.<br> This will not happen:</p> <pre><code>a,b,,d c,,, </code></pre> <p>This might help:</p> <pre><code>CREATE TABLE #original ( id int ,A INT, B INT, C INT, D INT ); INSERT INTO #original SELECT 0,1,2,null,4 union select 1,null,null,3,null --SELECT 0,1,2,3,null --union --select 1,4,null,null,null select * from #original order by id asc DROP TABLE #original </code></pre>

    2. COIm new to stack overflow. What do I do? I commented on the last question that none of the suggested answers worked. No one responded so I tweaked the question provided better examples and reposted.

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.
