What are the two types of stored procedures?

• User-Defined Stored Procedure.
• CLR Stored Procedure.

Why stored procedure is better than query?

every query is submited it will be compiled & then executed. where as stored procedure is compiled when it is submitted for the first time & this compiled content is stored in something called procedure cache,for subsequent calls no compilation,just execution & hence better performance than query.

What are the advantages of using a stored procedure?

Advantages of Stored Procedures

• To 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.

Why you shouldn’t use stored procedures?

Stored procedures promote bad development practices, in particular they require you to violate DRY (Don’t Repeat Yourself), since you have to type out the list of fields in your database table half a dozen times or more at least. This is a massive pain if you need to add a single column to your database table.

What are the disadvantages of stored procedures?

• Testability. 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.

Implement referential integrity across databases.
