Question

I am looking to create a temporary table which is used as an intermediate table while compiling a report.

For a bit of background I am porting a VB 6 app to .net

To create the table I can use…

SELECT TOP 0 * INTO #temp_copy FROM temp;

This creates an empty copy of temp, But it doesn’t create a primary key

Is there a way to create a temp table plus the constraints?

Should I create the constraints afterwards?

Or am I better off just creating the table using create table, I didn’t want to do this because there are 45 columns in the table and it would fill the procedure with a lot of unnecessary cruft.

The table is required because a lot of people may be generating reports at the same time so I can’t use a single intermediary table

Answer 1

Do you actually need a Primary Key? If you are flitering and selecting only the data needed by the report won’t you have to visit every row in the temp table anyway?
