    <p>Seems that you are able to get the column names, so I'm assuming you can get to the column types. So you can do this (pesudo code)</p> <pre><code>CREATE TABLE #XXX (Measure &lt;type&gt;) // generate scripts like SET @SQL = N'ALTER TABLE #XXX ADD '+ ColumnName+' '+ColumnTypeInfo EXEC SP_ExecuteSQL @SQL // SET @query = 'INSERT INTO #XXX ([MEASURE], '+@cols+') SELECT [Measure],' + @cols + ' FROM ( SELECT [NewName], [Measure], [Amount] FROM #UnpivottedData x ) x PIVOT ( SUM(Amount) FOR [NewName] in (' + @cols + ') ) p '; EXECUTE(@query); </code></pre> <p>P.S. </p> <ol> <li>I, myself, would choose <code>EXEC sp_executeSQL @SQL</code> over <code>EXEC (@SQL)</code>, but in this case is just a matter of taste</li> <li>I would simplify the code - you don't really need the <code>STUFF</code> part because you need your first comma in your concatenation, so there is no need to remove it. Also, you are forcing an XML column ( with the <code>TYPE</code> clause) only to convert it to <code>NVARCHAR</code></li> </ol> <p><strong>Later edit</strong></p> <p>Disclaimer: this is not tested, as I didn't have your table structure and data</p> <pre><code>DECLARE @cols NVARCHAR(MAX), @query NVARCHAR(MAX), @alter_query NVARCHAR(max); SET @cols = ( SELECT ',' + QUOTENAME(b."NewName") FROM ( SELECT myKey, win = SUM(win) FROM xxx.dbo.yyy GROUP BY myKey ) x INNER JOIN #NameSwitch b ON x.myKey = b.myKey ORDER BY x.win DESC FOR XML PATH('') ) -- this will render smth like ",col1,col2" SET @alter_query = ( SELECT ';ALTER TABLE #XXX ADD ' + QUOTENAME(b."NewName") +' '+ QUOTENAME(b."ColType") +' NULL' FROM ( SELECT myKey, win = SUM(win) FROM xxx.dbo.yyy GROUP BY myKey ) x INNER JOIN #NameSwitch b ON x.myKey = b.myKey ORDER BY x.win DESC FOR XML PATH('') ) -- this will render smth like ";ALTER TABLE #XXX ADD col1 VARCHAR(MAX);ALTER ..." CREATE TABLE #XXX (Measure INT NULL) EXEC sp_ExecuteSQL @alter_query SET @query = 'INSERT INTO #XXX (Measure+'@Cols+') SELECT [Measure]' + @cols + ' FROM ( SELECT [NewName], [Measure], [Amount] FROM #UnpivottedData x ) x PIVOT ( SUM(Amount) FOR [NewName] in (' + STUFF(@cols, 1, 1, '') + ') -- here you need the STUFF to remove the first comma ) p '; EXEC sp_ExecuteSQL @Query SELECT * from #XXX </code></pre>

    1. CO+1 @Daniel thanks for the help and the extra tips; I think yours is probably more what I was looking for (although the use of `##` tables in the other answer is pretty nifty). Are you saying I can just drop 'STUFF' and it will still run? Have you got time to simplify my `SET @cols = ...` script and place the simplified version in your answer?

    3. COthanks for all the help/advice - it all seems to work ok - I think I need to read up about this `FOR XML PATH` as it seems pretty powerful

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.
