sql query takes more time when run in a view

Question

HI all,

I have a huge sql query. When i put that query in a stored Proc it takes 5 seconds to execute which i run it just as a query it takes 4-5 seconds but when i run

Answer 1

I agree with Vash in that the additional time when run as a vaiew may be due to the extra time to compile an execution plan.

Try running this

Set Statistics Time On
Select * from view

and then Set Statistics On
Exec yourSPHere

You'll get something like this

SQL Server parse and compile time:
CPU time = 0 ms, elapsed time = 1 ms.

SQL Server Execution Times: CPU time = 0 ms, elapsed time = 1 ms.

(5475 row(s) affected) Table 'ContactBase'. Scan count 1, logical reads 428, physical reads 0, read-ahead reads 0, lob logical reads 0, lob physical reads 0, lob read-ahead reads 0.

SQL Server Execution Times: CPU time = 47 ms, elapsed time = 470 ms.

If the "SQL Server parse and compile time:" accounts for the difference between the two times that your answer is that the View is having to Create a execution plan each time while the Sproc is using a cached execution plan.
