This seems relatively simple, but apparently it's not.
I need to create a temp table based on an existing table via the select into syntax:
SELECT * INTO #TEMPTABLE FROM EXISTING_TABLE
The problem is, the existing table name is accepted via a parameter...
I can get the table's data via:
execute ('SELECT * FROM ' + @tableName)
but how do I marry the two so that I can put the results from the execute directly into the temp table.
The columns for each table that this is going to be used for are not the same so building the temp table before getting the data is not practical.
I'm open to any suggestions except using a global temp table.
Update:
This is completely ridiculous, BUT my reservations with the global temp table is that this is a multi user platform lends itself to issues if the table will linger for long periods of time...
Sooo.. just to get past this part I've started by using the execute to generate a global temp table.
execute('select * into ##globalDynamicFormTable from ' + @tsFormTable)
I then use the global temp table to load the local temp table:
select * into #tempTable from ##globalDynamicFormTable
I then drop the global table.
drop table ##globalDynamicFormTable
this is dirty and I don't like it, but for the time being, until i get a better solution, its going to have to work.
In the End:
I guess there is no way to get around it.
The best answer appears to be either;
Create a view in the execute command and use that to load the local temp table in the stored procedure.
Create a global temp table in the execute command and use that to load the local temp table.
With that said i'll probably just stick with the global temp table because creating and dropping views is audited in my organization, and I'm sure they are going to question that if it starts happening all the time.
Thanks!

Take a look at OPENROWSET
, and do something like:
SELECT * INTO #TEMPTABLE FROM OPENROWSET('SQLNCLI'
, 'Server=(local)\SQL2008;Trusted_Connection=yes;',
'SELECT * FROM ' + @tableName)
How I did it with a pivot in dynamic sql (#AccPurch was created prior to this)
DECLARE @sql AS nvarchar(MAX)
declare @Month Nvarchar(1000)
--DROP TABLE #temp
select distinct YYYYMM into #temp from #AccPurch AS ap
SELECT @Month = COALESCE(@Month, '') + '[' + CAST(YYYYMM AS VarChar(8)) + '],' FROM #temp
SELECT @Month= LEFT(@Month,len(@Month)-1)
SET @sql = N'SELECT UserID, '+ @Month + N' into ##final_Donovan_12345 FROM (
Select ap.AccPurch ,
ap.YYYYMM ,
ap.UserID ,
ap.AccountNumber
FROM #AccPurch AS ap
) p
Pivot (SUM(AccPurch) FOR YYYYMM IN ('+@Month+ N')) as pvt'
EXEC sp_executesql @sql
Select * INTO #final From ##final_Donovan_12345
DROP TABLE ##final_Donovan_12345
Select * From #final AS f
DECLARE @count_ser_temp int;
DECLARE @TableName AS VARCHAR(100)
SELECT @TableName = 'TableTemporal'
EXECUTE ('CREATE VIEW vTemp AS
SELECT *
FROM ' + @TableTemporal)
SELECT TOP 1 * INTO #servicios_temp FROM vTemp
DROP VIEW vTemp
-- Contar la cantidad de registros de la tabla temporal
SELECT @count_ser_temp = COUNT(*) FROM #servicios_temp;
-- Recorro los registros de la tabla temporal
WHILE @count_ser_temp > 0
BEGIN
END
END
declare @sql varchar(100);
declare @tablename as varchar(100);
select @tablename = 'your_table_name';
create table #tmp
(col1 int, col2 int, col3 int);
set @sql = 'select aa, bb, cc from ' + @tablename;
insert into #tmp(col1, col2, col3) exec( @sql );
select * from #tmp;
