When should I use stored procedures and when should I use views in SQL Server?
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..
What is the 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.
What are the disadvantages of stored procedures?
The main disadvantages of stored procedures are given below:Testing – Testing of a logic which is encapsulated inside a stored procedure is very difficult. … Debugging – … Versioning – … Cost – … Portability –
When should I use stored procedures?
The benefits of using stored procedures in SQL Server rather than application code stored locally on client computers include:They allow modular programming.They allow faster execution.They can reduce network traffic.They can be used as a security mechanism.
Which is better view or stored procedure?
In short, based on my experience in some complex queries, Stored procedure gives better performance than function. But you cannot use results of stored procedure in select or join queries. … Everything you can do in a view you can do in a stored procedure. But in a stored procedure, you can do with much more flexibility.
Can we use view in stored procedure?
Stored Procedures : They are a collection of pre-executed sql Statements where you can send the parameters as input and retrieve the output data. Views can be used in the Stored Procedure but the Stored Procedure cannot be used in Views…!
How do you view a procedure?
To view the definition a procedure in 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.
Why Stored procedures are bad?
Stored procedures require you to reinvent wheels. … Very often, you will end up reinventing these wheels using copy and paste code, which again is a bad practice. 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.
What is the use of stored procedures?
What is a Stored Procedure? 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.
What is the purpose of a stored procedure?
A stored procedure is used to retrieve data, modify data, and delete data in database table. You don’t need to write a whole SQL command each time you want to insert, update or delete data in an SQL database. A stored procedure is a precompiled set of one or more SQL statements which perform some specific task.
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.
Where are views stored?
View is a simple SQL statement that is stored in database schema (INFORMATION_SCHEMA. Views). So when ever we call the view the SQL statement gets executed and return the rows from main physical table. You can also tell the view as a Logical table that store the defination (the sql statement) but not the result.
