T-SQL: Rotate Columns into Rows, Take 2

I posted some code yesterday that rotates one row of sql results into a vertical name/value result set.
It serves its purpose. But it was weak: you had to pass it straight forward select statements that return one result, and you had to piece together the arguments, rather that just giving it a SQL statement and letting it do its job.

The code below is an improvement.

It will take arbitrary well formed sql statements of any sort and invert them into name value pairs. It is not intended to be high performance code. And it shamelessly uses a global temp table and three cursor loops (although I think it could be refactored to two) two cursor loops.

/*
Rotate 'select top 1 * from Production.Product'
*/
alter procedure Rotate(@sql nvarchar(1000)) as

set nocount on

set @sql = replace(@sql, ' from ', ' into ##t from ')

exec sp_executesql  @sql

declare @columnName varchar(25)

declare c2 cursor dynamic for select sc.name from tempdb..sysobjects so 
	inner join tempdb..syscolumns sc on sc.id = so.id 
	where so.name like '##t%'
open c2

fetch next from c2 into @columnName

	set @declareSql = @declareSql  + 'declare @' + @columnName + ' varchar(1000)

	set @insertSql = @insertSql + ';insert #namevalue values(''' + @columnName + ''', @' + @ColumnName + ')'

end
