Question: Which Is Better Stored Procedure Or Function?

Is SQL faster than C#?

They are both as fast as possible, if you make good code and good queries.

SQL Server also keeps a lot of statistics and improve the return query – c# did not have this kind of part, so what to compare ?.

Why we Cannot call stored procedure?

You cannot execute a stored procedure inside a function, because a function is not allowed to modify database state, and stored procedures are allowed to modify database state. … User-defined functions cannot be used to perform actions that modify the database state.

What is difference between function and stored procedure?

The function must return a value but in Stored Procedure it is optional. Even a procedure can return zero or n values. Functions can have only input parameters for it whereas Procedures can have input or output parameters. Functions can be called from Procedure whereas Procedures cannot be called from a Function.

Why stored procedure is 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. This all costs time.

Why you should not use stored procedures?

Stored procedures are difficult to unit test. With an ORM, you can mock your database code so as to be able to test your business logic quickly. With stored procedures, you have to rebuild an entire test database from scratch. Stored procedures offer no performance advantage whatsoever.

What is the advantage of using stored procedure?

To help you build powerful database applications, stored procedures provide several advantages including better performance, higher productivity, ease of use, and increased scalability.

Can SQL function call stored procedure?

If a function called a stored procedure, the function would become able to have side-effects. So, sorry, but no, you can’t call a stored procedure from a function. Another option, in addition to using OPENQUERY and xp_cmdshell, is to use SQLCLR (SQL Server’s “CLR Integration” feature).

Which is better view or stored procedure?

Views should be used to store commonly-used JOIN queries and specific columns to build virtual tables of an exact set of data we want to see. Stored procedures hold the more complex logic, such as INSERT, DELETE, and UPDATE statements to automate large SQL workflows.

When you should use a function over a procedure?

Procedure can return zero or n values whereas function can return one value which is mandatory. Procedures can have input, output parameters for it whereas functions can have only input parameters.More items…•

Are views faster than queries?

Views make queries faster to write, but they don’t improve the underlying query performance. … In short, if an indexed view can satisfy a query, then under certain circumstances, this can drastically reduce the amount of work that SQL Server needs to do to return the required data, and so improve query performance.

How can you tell if a stored procedure is slow?

When you need to find out why a stored procedure is running slow, here’s the information to start gathering:Check to see if the plan is in the cache. … Collect a set of parameters that work. … Find out if those parameters are fast, slow, or vary. … Find out if the stored proc does any writes.More items…•

How can we optimize stored procedure?

Optimizing Stored Procedures In SQL ServerThe simplest guidance is do not create the stored procedure with prefix “sp_”. … Include the SET NOCOUNT ON statement as the first statement of the procedure.Do not write “Select count(*) from Table” statement to get the count of the records. … Try to avoid dynamic SQL queries as much as possible.More items…•

Which is used to call the stored procedures and functions?

CallableStatement interface is used to call the stored procedures and functions. We can have business logic on the database by the use of stored procedures and functions that will make the performance better because these are precompiled.

How do you execute a stored procedure?

To execute a stored procedure Expand the database that you want, expand Programmability, and then expand Stored Procedures. Right-click the user-defined stored procedure that you want and click Execute Stored Procedure.

Can function return multiple values?

Even though a function can return only one value but that value can be of pointer type. … If we want the function to return multiple values of same data types, we could return the pointer to array of that data types. We can also make the function return multiple values by using the arguments of the function.

Can we call a procedure inside a function?

7 Answers. You cannot execute a stored procedure inside a function, because a function is not allowed to modify database state, and stored procedures are allowed to modify database state. … Therefore, it is not allowed to execute a stored procedure from within a function.

How do you improve database performance?

The Path to Improving Database PerformanceImprove your indexing strategies. … Steer clear of correlated subqueries and coding loops. … Keep certain files on separate disks. … Upgrade your hardware. … Know who has access. … Check your connection capacity. … Get smart about caching. … More quick tips for boosting database performance.More items…•

Do stored procedures improve performance?

Stored procedures improve database performance as they allow cached query plans to be reused. In the case of dynamic SQL, you will have to use parameterized queries to increase cached query plan reusability.

What does a stored procedure do?

A stored procedure is a prepared SQL code that you can save, so the code can be reused over and over again. … You can also pass parameters to a stored procedure, so that the stored procedure can act based on the parameter value(s) that is passed.
