Do stored procedure runs faster than query?
Stored procedures are precompiled and optimised, which means that the query engine can execute them more rapidly. By contrast, queries in code must be parsed, compiled, and optimised at runtime.
Why stored procedure are used?
By grouping SQL statements, a stored procedure allows them to be executed with a single call. This minimizes the use of slow networks, reduces network traffic, and improves round-trip response time. OLTP applications, in particular, benefit because result set processing eliminates network bottlenecks.
Are there any stored procedures that have no plans in Cache?
Many, maybe all, of the statements inside the stored procedures also didn’t have plans in cache. Some of the stored procedures execute pretty frequently like a few times per second. No memory pressure whatsoever. One of the servers has far more hardware than is needed.
Is the execution plan still in the cache?
Thinking about, you haven’t stated that you checked whether the execution plan is still in cache or not. You should query the cache to figure that out. However, since you say your query runs only once a day, the plan might just be expired.
Which is better execution plan or stored procedure?
For a stored procedure, the execution plan is precomputed, which leads to a slight benefit over ordinary queries the first time the stored procedure is invoked. Execution Plan Caching and Reuse article on MSDN doesn’t make difference between parametrized queries and stored procedures.
Where does SQL Server store the execution plan?
After you run a query, SQL Server may keep the data in cache. Therefore, it doesn’t have to read from disk to get the information, instead it can pull it from RAM, which is much faster. While your execution plan may also be stored in the plan cache, I highly doubt compiling an execution plan is increasing your query execution time seven-fold.
