选择null作为testdate进入#temp_table

Question

Is there a way to insert/update a datetime value ( getdate() ) into a temp table created like the following:

select id, null as testdate
into #temp_table

and then later statement:

update #temp_table 
set testdate=getdate()

I get error:

cannot convert datetime into int...

Thanks.

Cast the column in the select into

select id, cast(null as datetime) as testdate
into #temp_table
