Temp Table in view

Question

I Know we cannot use Temp table,table variable in View but i want to know the reason behind it

Answer 1

Assuming the second batch is executed from a 2nd connection, there is no doubt that the query should return 46 on that 2nd connection. If the 1st connection would run the same SELECT statement, it should return 33.
And if the definition of the temp tables are
CREATE TABLE #temp(a int NOT NULL)
CREATE TABLE #temp(b float NOT NULL)
Keep in mind how view definitions are stored in SQL Server.
I don't know exactly why the original poster wanted this, but what does make sense is of course a temporary view, and preferrably one that does not require a batch of its own. A couple of years ago, I wrote a stored procedure where I found that I repeated
the same conditions all over again. This made me year for something like a module-level CTE and I submitted this Connect item:
