# Explain the SQL Stored Procedures.

#### SQL Stored Procedure

SQL [Stored Procedures](https://www.mindstick.com/forum/540/using-stored-procedures-with-entity-framework-in-an-asp-dot-net-application) The powerful feature of SQL databases is that they allow you to embed complex SQL logic and [complex business](https://www.mindstick.com/forum/161972/is-sql-more-vital-for-solving-complex-business-problems-or-power-bi-tableau-for-insights) rules in reusable blocks of code.

Here is a breakdown of what they do and how they work.

#### What is a Stored Procedure

A [stored procedure](https://www.mindstick.com/articles/803/using-stored-procedure-in-asp-dot-net) is a collection of pre-collected SQL statements and information about flow options stored in a database. They can retrieve parameters, perform operations, and return results, making it versatile for different projects.

#### Key Features of Stored Procedures

**Encapsulation-** [Combine multiple](https://www.mindstick.com/forum/160929/help-with-writing-a-query-to-combine-multiple-rows-into-one-in-sql-server) SQL statements into a single object. This encapsulation makes it easier to deal with complex logic.

**Reusability-** Once defined, the stored procedure can be executed repeatedly without having to rewrite the SQL code.

**Performance-** Stored routes are collected once and stored in the database, which can [improve performance](https://www.mindstick.com/forum/160287/how-can-parameterized-stored-procedures-improve-performance-compared-to-dynamic-sql-queries) due to reduced search time

**Security-** Data can be helped to be protected by limiting direct access to the underlying tables. Users can be allowed to execute a stored procedure without accessing the base tables.

**Parameterization-** Stored objects can accept parameters, allowing dynamic actions to be taken based on input values.

#### Basic Structure of a Stored Procedure

Here is a simple syntax of creating a stored [procedure in SQL](https://www.mindstick.com/forum/158350/what-is-a-stored-procedure-in-sql-server-and-how-to-create-one) Server,

```plaintext
USE DatabaseName
GO
CREATE PROCEDURE Pro_ProcedureName
(
@Parameter1 datatype,
@Parameter2 datatype,
........
)AS
BEGIN
SET NOCOUNT ON;
--SQL statement here
SET NOCOUNT OFF;
END
```

- `USE DatabaseName`- the SQL database name in which you want to create stored procedure.
- `CREATE PROCEDURE/PROC` is the SQL statement that is used to create a stored procedure.
- `Pro_ProcedureName` is the name of stored procedure.
- `@Parameter1 datatype`and `@Parameter2 datatype` is the parameters with datatype which are used to accept the values and [return the result](https://www.mindstick.com/forum/159730/how-can-i-return-the-result-from-the-ajax-call) based on it.
- `BEGIN … END` is the body area of stored procedure in which SQL statement is placed.
- `SET NOCOUNT ON/OFF` is used to ignore the affected row that is returned by the SQL statement in the body area.

## Example-

Here are the two SQL tables, **Employees** with the columns, `EmpId`, `EmpName`, `Gender`, `Salary`, `DepartmentId` and **Departments** table with the columns, `ID`, `Name`, `Location`

Let's create a stored procedure that accepts the department name as a parameter and returns all the employees of that department,

```plaintext
USE MyCollegeDb
GO
CREATE PROCEDURE [dbo].[Pro_GetEmpbyDepartment]
(
@DeptName NVARCHAR(50) -- parameter
)AS
BEGIN
SET NOCOUNT ON;
 -- body area
 SELECT Emp.EmpId, Emp.EmpName, D.Name AS DepartmentName, Emp.Gender, Emp.Salary
 FROM Employees AS Emp INNER JOIN Departments D ON D.ID = Emp.DepartmentId
 WHERE D.Name = @DeptName
 -- use for better comparision D.Name LIKE '%'+@DeptName+'%'
SET NOCOUNT OFF;
END
```

Now, execute the stored procedure,

If you notice in the above result table all the employees' data is returned from the **'HR'** department.

## SQL Stored Procedure Without Parameter

you can also create stored procedure without any parameter or parameterless stored procedure, Let's see the example below,

```plaintext
USE MyCollegeDb
GO
CREATE PROCEDURE [dbo].[Pro_GetEmployeeDetails]
AS
BEGIN
SET NOCOUNT ON;
 -- body area
 SELECT Emp.EmpId, Emp.EmpName, D.Name AS DepartmentName, Emp.Gender, Emp.Salary
 FROM Employees AS Emp INNER JOIN Departments D ON D.ID = Emp.DepartmentId
 ORDER BY Emp.EmpName DESC
SET NOCOUNT OFF;
END
```

## Output-

#### Benefits of Using Stored Procedures

**Modularity-** Break up complex logic into manageable chunks.\
**Maintainability-** Changes can be made in one area without affecting the entire application.\
**Consistency-** Ensures logic is consistently addressed across applications and users.

#### Use Cases for Stored Procedures

**Data Manipulation-** Inserting, updating, or deleting records based on extreme circumstances.\
**[Batch processing](https://www.mindstick.com/forum/158518/what-is-the-difference-between-batch-processing-and-real-time-processing-in-big-data-applications)-** Executing multiple SQL statements as a batch to improve performance.\
**Data Validation-** Implementation of business rules and verification checks before data manipulation.\
**Reporting-** Gathering and organizing data and producing complex reports.

\

Stored procedures are an important part of **SQL** design that provide significant benefits in [terms of performance](https://www.mindstick.com/forum/160322/what-are-the-benefits-of-set-in-terms-of-performance-and-functionality), security, and maintainability. It is widely used in enterprise applications to efficiently manage database interactions.
