Why Stored Procedures Are Bad?

Which is better view or stored procedure?

In general, a Stored Procedure stands a good chance of being faster than a direct SQL statement because the server does all sorts of optimizations when a stored procedure is saves and executed the first time.

A view is essentially a saved SQL statement..

Is a stored procedure faster than a query?

“Stored procedures are precompiled and cached so the performance is much better.” 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 stored procedure is better than query?

The primary advantage to parameterized queries and stored procedures is that they don’t have to go through the compile process over and over again. Stored procedures also offer some additional security aspects. Ad hoc queries are just query strings passed to the server directly. They are compiled and stored in memory.

Are stored procedures dead?

Stored Procedures are nowhere near dead. While Entity Framework may be used to create the DB (Code First), Code First can be set to create procedures for CRUD ops.

Are stored procedures more secure?

Parametrized SQL does take care of this, but technically stored procedures are still a little more secure, because the user accessing information in the table doesn’t need Read Access. It only needs to be able to execute the stored procedure. Depending on your need this may or may not come into play.

Where are stored procedures stored?

The stored procedure are stored as named objects in the SQL Server Database Server. When you call a stored procedure for the first time, SQL Server creates an execution plan and stores it in the cache.

Is SQL Server dying?

No. SQL Server is not dying. I see more and more people shying away from those open source technologies and coming to SQL Server every day. Those platforms are good for some things, but they work best when used in conjunction with SQL Server or some other major RDBMS.

Is stored procedure faster than query in MySQL?

Stored procedures have many other benefits than speed, security being high on the list. … In MySQL or any other SQL server as MSSQL or Oracle, stored procedures increase dramatically the speed of the queries involved because this are already compiled.

How do I save a stored procedure?

You can change the SQL code, then save the stored procedure to update the stored procedure in the database. To save a stored procedure to the database, right-click the editor and select Save to Database from the menu or press Ctrl+S. Next, you can paste this statement into Query Designer and modify it as before.

How do I view stored procedures?

To view the definition a procedure in Object ExplorerIn Object Explorer, connect to an instance of Database Engine and then expand that instance.Expand Databases, expand the database in which the procedure belongs, and then expand Programmability.More items…•

Can a view call a stored procedure?

Well, you can’t use temp tables in a view (which would totally solve the problem, because temp tables rock). You can do the subqueries-to-temp table stuff in a stored procedure, but you can’t call a stored procedure from a view.

Do stored procedures prevent SQL injection?

Stored procedures only directly prevent SQL injection if you call them in a paramerized way. If you still have a string in your app with the procedure name and concatenate parameters from user input to that string in your code you’ll have still have trouble.

Why executing stored procedures from triggers is not a good idea?

No, you do not need cursors. When your trigger is executed, if more than one row is affected, there will be multiple rows in inserted / deleted pseudo tables too. In your case you do not read which rows are updated either, so just run the procedure. … Looping with cursors is practically never good idea in the database.

Why use stored procedures?

Following are the advantages of stored procedures: Since stored procedures are compiled and stored, whenever you call a procedure the response is quick. you can group all the required SQL statements in a procedure and execute them at once. Since procedures are stored on the database server which is faster than client.

What is difference between stored procedure and function?

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.

What are the disadvantages of stored procedures?

-Disadvantages of the Stored procedure.A large number of Logical operations increase CPU usage.Difficult to Debug.Not easy to Develop and Maintain.Not designed for developing Complex or Flexible business logic.

Can a trigger call a stored procedure?

MySQL allows you to call a stored procedure from a trigger by using the CALL statement. By doing this, you can reuse the same stored procedure in several triggers. However, the trigger cannot call a stored procedure that has OUT or INOUT parameters or a stored procedure that uses dynamic SQL.

How can stored procedure improve performance?

Improve stored procedure performance in SQL ServerUse SET NOCOUNT ON. … Use fully qualified procedure name. … sp_executesql instead of Execute for dynamic queries. … Using IF EXISTS AND SELECT. … Avoid naming user stored procedure as sp_procedurename. … Use set based queries wherever possible. … Keep transaction short and crisp.

Is a stored procedure an API?

Stored procedures: the database-as-API mindset An Application Programming Interface (API) is a set of interfaces that allows a system to interact with another system. … Stored procedures are the only construct available in SQL Server that can provide the type of interfaces necessary for a comprehensive data API.
