# What are SQL Stored Procedures in the Database?

#### SQL Stored Procedure

SQL Stored Procedures are a collection of one or more precompiled SQL statements that are stored and executed on the database server. It is used to prevent and automate recurrence of complex or frequent database operations, improving performance, stability and security.

#### Key Characteristics of Stored Procedures

## Precompiled

[SQL procedures](https://www.mindstick.com/blog/304484/explain-the-sql-stored-procedures) are compiled once and stored in the database. This reduces the need for repeated parsing and aggregation of SQL statements, improving efficiency.

## Encapsulation

Multiple SQL statements are compiled into a single operation, allowing you to create complex programs and logic without repeating the code in multiple places

## Reusability

Stored methods can be reused across multiple application components or applications, ensuring consistent logic and reducing code duplication

## Security

Using stored procedures allows you to limit direct access to database tables, reduce the risk of SQL injection, and control access to They a users are given a stored procedure without direct access to the underlying table.

## Parameters

Stored procedures can accept parameters, which allow for dynamic execution and optimization based on input values.

## Example-

```plaintext
-- Example in SQL Server
CREATE PROCEDURE GetEmployeeById
   @EmployeeId INT
AS
BEGIN
   SELECT * FROM Employees
   WHERE EmployeeId = @EmployeeId;
END;
```

Use the following SQL statement to execute the stored procedure,

```plaintext
EXEC GetEmployeeById @EmployeeId = 123;
```

#### Advantages

## Performance

Improved execution speed due to precompilation.\
Configuration: Easy to manage and update business logic in one place.\

## Security

Maintaining database access and processing.

\
Stored Procedure is a powerful tool for managing and optimizing database interactions, providing a structured approach to repetitive tasks and complex workflows
