Why we use stored procedure?
What is a 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..
Is stored procedure faster than query?
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 difference between stored proc and query?
What is the difference between a query and stored procedure? query and stored procedure do the same thing but the difference is that a query should be compiled everytime the query is executed,while the stored procedure is in compiled form when executed first time.
What is function in stored procedure?
The function always returns a value. Stored Procedure will not return a value, but the procedure can return “0” or n values. Functions have only input parameters for it. Whereas, Procedures can have output or input parameters.
Can we write procedure inside trigger?
Is it possible to write a procedure or function inside a database trigger, and vice versa? Yes. You can call a procedure or function from a database trigger.
How do we call a stored procedure?
The first and most common approach is for an application or user to call the procedure. The second approach is to set the procedure to run automatically when an instance of SQL Server starts. When a procedure is called by an application or user, the Transact-SQL EXECUTE or EXEC keyword is explicitly stated in the call.
How do I create a stored procedure in SQL?
How to create a SELECT stored procedure? Click on your Database and expand “Programmability” item and right click on “Stored Procedures” or press CTRL + N to get new query window. In the query area between BEGIN and END, type your SELECT statement to select records from the table.
How is view stored in database?
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.
Can I call stored procedure in view?
7 Answers. This construction is not allowed in SQL Server. An inline table-valued function can perform as a parameterized view, but is still not allowed to call an SP like this. I was able to call stored procedure in a view (SQL Server 2005).
How do I view a procedure in SQL Server?
Using SQL Server Management Studio Expand Stored Procedures, right-click the procedure and then click Script Stored Procedure as, and then click one of the following: Create To, Alter To, or Drop and Create To. Select New Query Editor Window. This will display the procedure definition.
What is MySQL stored procedure?
A procedure (often called a stored procedure) is a subroutine like a subprogram in a regular computing language, stored in database. A procedure has a name, a parameter list, and SQL statement(s). All most all relational database system supports stored procedure, MySQL 5 introduce stored procedure.
Can we call trigger manually?
Yes,triggers are executed manually. Triggers are special types of Stored Procedures that are defined to execute automatically in place of or after data modifications. They can be executed automatically on the INSERT, DELETE and UPDATE triggering actions.
Can we call trigger in stored procedure?
You cant call Trigger from Stored Procedure, as Trigger are created on table and get fired implicitly. But you can call stored procedure to from trigger, but do remeber it should not be recursive.
Is view a 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.
What is a procedure?
1a : a particular way of accomplishing something or of acting. b : a step in a procedure. 2a : a series of steps followed in a regular definite order legal procedure a surgical procedure. b : a set of instructions for a computer that has a name by which it can be called into action.
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.
Is a view faster than a stored procedure?
A view is essentially a saved SQL statement. 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.
What is an example of a trigger?
Trigger: A trigger is a stored procedure in database which automatically invokes whenever a special event in the database occurs. For example, a trigger can be invoked when a row is inserted into a specified table or when certain table columns are being updated.
