Data Modification LanguageDML (Data Modification Language) triggers.
This is the most used class of triggers..
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.
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.
When should I use stored procedures?
We use stored procedures for all of our reporting needs. They can usually retrieve the data faster and in a way that the report can just spit out directly instead of having to do any kind of calculations or similar.
Which is faster query or stored procedure?
“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.
Are views faster than queries?
MS SQL Indexed views are faster than a normal view or query but indexed views can not be used in a mirrored database invironment (MS SQL). A view in any kind of a loop will cause serious slowdown because the view is repopulated each time it is called in the loop. Same as a query.
What is the purpose of 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 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.
Why do we need triggers?
Triggers help the database designer ensure certain actions, such as maintaining an audit file, are completed regardless of which program or user makes changes to the data. … The programs are called triggers since an event, such as adding a record to a table, fires their execution.
What are the types of stored procedures?
Different Types of stored procedure sql ServerSystem 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. These procedures are created by the user for own actions. … CLR Stored Procedure.
How do I create a stored procedure?

What are the disadvantages of stored procedures?
Drawbacks of Stored ProceduresTestability. First and foremost business logic which is encapsulated in stored procedures becomes very difficult to test (if tested at all). … Debugging. … Versioning. … History. … Branching. … Runtime Validation. … Maintainability. … Fear of change.More items…•
What is difference between stored procedure and trigger?
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).
What are the advantages of stored procedure and stored procedure?
A Stored Procedure can be used as a modular programming which means create once, store and call for several times whenever it is required. This supports faster execution. It also reduces network traffic and provides better security to the data.
What is the advantage of 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.
Where do we 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.
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 are the advantages and disadvantages of stored procedures?
The procedure calls are quick and efficient as stored procedures are compiled once and stored in executable form….Portability –AdvantagesDisadvantagesIt is pre-compiled.Need expert developer, since difficult to write code.It reduces network traffic.It is database dependent.3 more rows•Jun 5, 2020
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.
What is a stored procedure and how is it used?
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.
