Help - To use Create #table in Exec command

Hi,
I need the use Create table #table command in the Exec command
Example
declare @.chr_CreateSql nVarchar(4000)
,@.err Varchar(255)
select @.chr_CreateSql = ' Create table #test (ss varchar(255))'
Exec (@.chr_CreateSql)
select * from #test
When I run this I get the following error
But when I change #test to ##test
It works fine.
The reason I need the create table in exec command the number of columns in
temp table is dynamic. Please help me to resolve this issue
Thanks

Every day, it seems.
EXEC() has its own scope. When EXEC() has finished, your #temp table no
longer exists.
You can fool it by doing this all in one EXEC() call:
EXEC('CREATE TABLE #test(ss VARCHAR(255)); SELECT * FROM #test')
Or, figure out a way to drop the temp table, or the dynamic SQL, or both.
Neither are considered "best practices"... dynamic SQL is treated quite well

This is a global temp table. I recommend you do not use this syntax unless
you know the pros and cons.

Why not use all the columns and then ignore the ones you don't need.
