Question: When Should I Use Stored Procedures?

Why use stored procedures instead SSIS?

Second, the graphical interface lets you build large, complex and reliable transforms much more easily than hand-crafted T-SQL.

And third, SSIS lets you more easily interact with additional external sources, which can be very handy for things like data cleansing..

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.

How does stored procedure work?

Stored procedures differ from ordinary SQL statements and from batches of SQL statements in that they are precompiled. The first time you run a procedure, Adaptive Server’s query processor analyzes it and prepares an execution plan that is ultimately stored in a system table.

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 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 are three advantages to using SQL?

Advantages of SQLHigh speed. Using the SQL queries, the user can quickly and efficiently retrieve a large amount of records from a database.No coding needed. In the standard SQL, it is very easy to manage the database system. … Well defined standards. … Portability. … Interactive language. … Multiple data view.

What is the use of begin and end in stored procedure?

BEGIN and END keywords are not required in Transact-SQL. BEGIN and END are used in Transact-SQL to group a set of statements into a single compound statement, so that control statements such as IF … ELSE, which affect the performance of only a single SQL statement, can affect the performance of the whole group.

Why do we use trigger?

In a DBMS, a trigger is a SQL procedure that initiates an action (i.e., fires an action) when an event (INSERT, DELETE or UPDATE) occurs. … Triggers are used to maintain the referential integrity of data by changing the data in a systematic fashion. Each trigger is attached to a single, specified table in the database.

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 are advantages of stored procedures?

Advantages of Stored ProceduresTo help you build powerful database applications, stored procedures provide several advantages including better performance, higher productivity, ease of use, and increased scalability. … Additionally, stored procedures enable you to take advantage of the computing resources of the server.More items…

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.

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 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.

Where are stored procedures used?

Another advantage to using stored procedures allows for multiple client applications written in any language and running on any platform to have consistent database routines. Each application uses the same procedures and simply has to embed a standard procedure call for the language in the calling program.

What is difference between views and stored procedures?

View is simple showcasing data stored in the database tables whereas a stored procedure is a group of statements that can be executed. A view is faster as it displays data from the tables referenced whereas a store procedure executes sql statements.
