Quick Answer: 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.

Which is faster stored procedure or function?

Stored Procedures can be fast, very fast, as they are pre-compiled. … A Stored Procedure will return results in a table form. Functions can be Scalar (returning a single result) or return Tabular data.

Is a view faster than a stored procedure?

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.

Why you should not use stored procedures?

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.

Which is better stored procedure or query?

There is no noticeable speed difference for stored procedures vs parameterized or prepared queries on most modern databases, because the database will also cache execution plans for those queries. … The main reason imo to still favor stored procedures today has more to do with security.

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.

How do I execute a stored procedure?

When should I use stored procedures and when should I use views in SQL Server?
