How do you view a procedure?

Select New Query Editor Window.
This will display the procedure definition..
Can we use view in stored procedure?
These base views can be created in two ways: Importing a database table, function or stored procedure directly from the graphical interface using introspection. Creating a view with the “Create from query” option using a SQL query on the data source.
How can you tell if a stored procedure is slow?
When you need to find out why a stored procedure is running slow, here’s the information to start gathering:Check to see if the plan is in the cache. … Collect a set of parameters that work. … Find out if those parameters are fast, slow, or vary. … Find out if the stored proc does any writes.More items…•
Why stored procedure is used?
A stored procedure provides an important layer of security between the user interface and the database. It supports security through data access controls because end users may enter or change data, but do not write procedures. … It improves productivity because statements in a stored procedure only must be written once.
Why view is faster than table?
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). … In this situation a temporary table using # or @ to hold your data to loop through is faster than a view or a query.
Why do we use views?
Views are used for security purposes because they provide encapsulation of the name of the table. Data is in the virtual table, not stored permanently. Views display only selected data. We can also use Sql Join s in the Select statement in deriving the data for the view.
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.
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.
Does stored procedure increase performance?
Stored procedures improve database performance as they allow cached query plans to be reused. … In the absence of parameterized query plans, SQL server automatically detects parameters and generates cached query plans resulting in improved performance.
What is the difference between view and stored procedure?
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. A view is a simple way to save a complex SELECT in the database.
Are stored procedure faster than queries?
Your statement that Stored Procedures are faster than SQL Queries is only partially true. … So if you call the stored procedure again, the SQL engine first searches through its list of query plans and if it finds a match, it uses the optimized plan.
Does View improve performance?
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.
Can we create indexes on views?
The first index created on a view must be a unique clustered index. … Creating a unique clustered index on a view improves query performance because the view is stored in the database in the same way a table with a clustered index is stored. The query optimizer may use indexed views to speed up the query execution.
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.
Which is better trigger or stored procedure?
Stored procedures can be invoked explicitly by the user. … On the other hand, trigger is a stored procedure that runs automatically when various events happen (eg update, insert, delete). Triggers are more like an event handler they run at the specific event. Trigger can not take input and they can’t return values.
