Getting access to a dynamic table from dynamic sql

Question

Good day StackOverflow

The table that I create from my dynamic sql can have any number of columns as it is a pivot table.

-- Pivot the table so we get the UW as columns rather than rows
DECLARE @SQL NVARCHAR(MAX)
SET @SQL = '
SELECT *
FROM #PreProcessed
PIVOT (SUM(Quotes)
        FOR [UW] IN (' + @UWColumns + ')
        ) AS bob'

I run this code to run my dynamic sql.

EXEC sp_executesql @SQL,
                  N'@UWColumns nvarchar(MAX)',
                  @UWColumns

My question is, how do I store the resulting table? Especially when I don't know how many columns it will have or even what the columns will be called?

I tried the code below but it doesn't work

   INSERT INTO #Temp
   EXEC sp_executesql @SQL,
                  N'@UWColumns nvarchar(MAX)',
                  @UWColumns

Thanks everyone

The only way I could find around this problem was to do all of my calculations in the dynamic sql. Which meant I had to work on two tables.

-- Pivot the table so we get the UW as columns rather than rows
DECLARE @SQL NVARCHAR(MAX)
SET @SQL = '
SELECT * INTO #temp
FROM #PreProcessed
PIVOT (SUM(Quotes)
        FOR [UW] IN (' + @UWColumns + ')
        ) AS bob

SELECT DISTINCT t1.Date, d.Declines AS ''Declines'' , '+@UWColumns+'
FROM #temp AS t1 LEFT OUTER JOIN
#Declines AS d ON t1.DATE = d.DATE
'

PRINT @SQL

EXEC(@SQL)

SQL Server uses SELECT * INTO ...., as opposed to the CREATE TABLE AS syntax. So you'll need to modify your dynamic sql to:

 SELECT * INTO <YOUR TABLE>
    FROM #PreProcessed
    PIVOT (SUM(Quotes)
            FOR [UW] IN (' + @UWColumns + ')
            ) AS bob'
