    <p>Perhaps you're making this more complicated than it needs to be. Partly because I couldn't wrap my little brain around the number of <code>PIVOT</code>/<code>UNPIVOT</code>/whatever combinations and a dynamic SQL "sea of red" would be necessary to pull this off. Since you know the table has exactly one row, pulling the value for each column can just be a subquery as part of a set of <code>UNION</code>ed queries.</p> <pre><code>DECLARE @sql NVARCHAR(MAX) = N'INSERT dbo.B([Key], Value) ' SELECT @sql += CHAR(13) + CHAR(10) + ' SELECT [Key] = ''' + REPLACE(name, '''', '''''') + ''', Value = (SELECT ' + QUOTENAME(name) + ' FROM dbo.A) UNION ALL' FROM sys.columns WHERE [object_id] = OBJECT_ID('dbo.A'); SET @sql = LEFT(@sql, LEN(@sql)-9) + ';'; PRINT @sql; -- EXEC sp_executesql @sql; </code></pre> <p>Result (I only created 4 columns, but this would work for any number):</p> <pre><code>INSERT dbo.B([Key], Value) SELECT [Key] = 'Column1', Value = (SELECT [Column1] FROM dbo.A) UNION ALL SELECT [Key] = 'Column2', Value = (SELECT [Column2] FROM dbo.A) UNION ALL SELECT [Key] = 'Column3', Value = (SELECT [Column3] FROM dbo.A) UNION ALL SELECT [Key] = 'Column4', Value = (SELECT [Column4] FROM dbo.A); </code></pre> <p>The most efficient thing in the world? Likely not. But again, for a one-row table, and hopefully a one-off task, I think it will work just fine. Just watch out for column names that contain apostrophes, if you allow those things in your shop...</p> <p><strong>EDIT</strong> sorry, couldn't leave it that way. Now it will handle apostrophes in column names and other sub-optimal naming choices.</p>

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.
