Why do we use sp?

Use of stored procedures can Reduce network traffic between clients and servers, because the commands are executed as a single batch of code. This means only the call to execute the procedure is sent over a network, instead of every single line of code being sent individually.

Using stored procedures can Help simplify and speed up the execution of SQL queries. Stored procedures can reduce network traffic between servers and clients, for example. This is a result of the commands being executed as a single batch of code rather than multiple.

A stored procedure is a prepared SQL code that you can save, so the code can be reused over and over again. So if you have an SQL query that you write over and over again, save it as a stored procedure, and then just call it to execute it.

The main purpose of stored procedures To hide direct SQL queries from the code and improve performance of database operations such as select, update, and delete data.

Stored procedures can be invoked explicitly by the user. It’s like a java program , it can take some input as a parameter then can do some processing and can return values. On the other hand, trigger is a stored procedure that runs automatically when various events happen (eg update, insert, delete).

A stored procedure is invoked as a function call instead of a SQL query. Stored procedures can have parameters for both passing values into the procedure and returning values from the call. Results can be returned as a result set, or as an OUT parameter cursor.

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.

Also, if you have a very complex query that could take a lot of horsepower on the client end, a stored procedure would help. Any query that could be dynamic should not be a SP. If it’s something that changes frequently, or something you need fast access to, it’s a bad idea to make an SP.

You can find the stored procedure In the Object Explorer, under Programmability > Stored Procedures As shown in the following picture: Sometimes, you need to click the Refresh button to manually update the database objects in the Object Explorer.

Expand the database that you want, expand Programmability, and then expand Stored Procedures. Right-click the user-defined stored procedure that you want and select Execute Stored Procedure. In the Execute Procedure dialog box, specify a value for each parameter and whether it should pass a null value.

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

Different Types of stored procedure sql Server

• System Defined Stored Procedure. These stored procedures are already defined in SQL Server. …
• Extended Procedure. Extended procedures provide an interface to external programs for various maintenance activities. …
• User-Defined Stored Procedure. …
• CLR Stored Procedure.

There are Four Different types of MySQL procedures: 1.

A view is essentially a saved SQL statement. Therefore, I would say that in general, A stored procedure will be likely to be faster than a view IF the SQL statement for each is the same, and IF the SQL statement can benefit from optimizations. Otherwise, in general, they would be similar in performance.

An index Contains keys built from one or more columns in the table or view. These keys are stored in a structure (B-tree) that enables SQL Server to find the row or rows associated with the key values quickly and efficiently. SQL Server documentation uses the term B-tree generally in reference to indexes.

Trigger functions invoked by per-row triggers can return a table row (a value of type HeapTuple) to the calling executor, if they choose. A row-level trigger fired before an operation has the following choices: It can return NULL to skip the operation for the current row.

What is the difference between a query and stored procedure? query and stored procedure do the same thing but the difference is that A query should be compiled everytime the query is executed,while the stored procedure is in compiled form when executed first time.

“Stored procedures are precompiled and cached So the performance is much better.” The stored procedure is stored in a pre-compiled form. we can’t require write code again and again.

Code reusability and better maintainability

It is easier to troubleshoot a stored procedure than inline query as we can isolate it. There is also a way to write unit test in SQL server which help to confirm the logic of stored procedure.

Stored procedures are simply a group of statements that perform some functions on the database. These functions can be insertion, updating, selecting or deleting rows on one or more database tables. Ad hoc queries on the other hand serves the same purpose as stored procedures with one big difference.

In the SQL RANK functions, we use the OVER() clause to define a set of rows in the result set.

A quick summary of SQL RANK Functions.

Storage of Execution Plan – One of the biggest reasons why you are facing slow procedures in SQL Server is probably because Your Execution plan is stored in the cache. To find out if it is in the cache, you need to search it there and see if it exists in the top 10 appearing plans.

Stored procedures handle large quantities of data much better; in fact EF has some limitations on how much data can be handled.

Well, SQL Server has an often-overlooked alternative to views and stored procedures that you should consider: Table-valued user defined functions (UDFs). Table-valued UDFs have all the important features of views and stored procedures and some additional functionality that views and stored procedures lack.
