Have you tried using SELECT INTO?

Hi

Below code is giving error Incorrect syntax near )

declare @cols as nvarchar(max) = '';

declare @query as nvarchar(max) = '';

select @cols = @cols + QuoteName(itemname) + ',' from (select distinct itemname from #temp)

as tmp

select @cols = substring(@cols,0,len(@cols))

set @query =

'select * into #FinalResult from

(select Name, ' + @cols + ' from (select name,quantity,itemname from #temp) x

pivot (sum(quantity) for itemname in (' + @cols + ')) piv ';

)

execute (@query)

Thanks

Try this

SET @query
    = N'select * into #FinalResult from

(select Name, ' + @cols
      + N' from (select name,quantity,itemname from #temp) x

pivot (sum(quantity) for itemname in (' + @cols + N')) piv 

) x';

Note that the temporary table will only exist within the scope of the dynamic statement here though, so after EXEC sys.sp_executesql @query has been run, the table would be dropped; so you wouldn't be able to refer to it outside of the dynamic pivot.

I suspect there's more to the story here; we already found out that the OP is asking about a dynamic pivot, rather than a standard one. What is the goal of putting the data into a (temporary) table here? Normally pivoting such as this is better off in your presentation layer; if you want to work with the data in your RDBMS leave it normalised.

Hi

It does not show results. It gives message 2 rows affected. I have written execute(@query) also

Thanks

Of course it won't, the data was inserted into a table, not returned to the application. If you want to INSERT it into a temporary table, why do you want to return the resultset to the application too? We definitely don't have the full picture; explain your full requirements.

Hi

Main requirement is to show data in Pivot & display Grand Totals of columns. Columns will be dynamic.

Display the results

Thanks

So as mentioned, why not pivot your data in the presentation layer; that is by far the best place. Otherwise, if you "must" do this in the SQL layer, I suggest switching to using conditional aggregation, then you don't have to clumb your data into a temporary table to then try and work out the grant totals too.

If you don't know how to do this, post your sample data as DDL and DML statements and show the results you want.

This should be done in the presentation layer (Excel, SSRS, PowerBI etc).

This is a "dynamic" Pivot. I don't use Pivots at all. They're generally slower and more difficult to manipulate than an ancient "Black Art" known as a CROSS TAB.

Whether the needed query is dynamic or not and if need to know more about CROOSSTabs, see the following article:

If the needed query does need to be dynamic, then also see the this article, as well...

RBAR is pronounced "ree-bar" and is a "Modenism" for Row-By-Agonizing-Row.
First step towards the paradigm shift of writing Set Based code:
________Stop thinking about what you want to do to a ROW... think, instead, of what you want to do to a COLUMN.

Change is inevitable... Change for the better is not.
