Using Stored Procedures - (BCA / B.Tech)

Stored Procedures in .NET in Hindi | Stored Procedures in .NET in Hindi:

A stored procedure is a powerful tool for database management.
It is used not only to improve performance, but it also increases code reuse and security.
Using it with .NET and C# is simple and effective.
All aspects of Stored Procedures are included.
This includes their introduction, use, execution, the process of sending parameters, and an example with C# in .NET.

Introduction to Stored Procedures in Hindi | Introduction to Stored Procedures:

A stored procedure is a database object that is a collection of one or more SQL statements programmed in SQL Server.
It is stored in the database and can be executed whenever needed.
The main use of a stored procedure is to fetch, update, or perform other operations on data from the database.
These improve performance, make code reusability possible, and increase database security.

Advantages of Stored Procedures in Hindi | Advantages of Stored Procedures

Improved performance: SQL Server pre-compiles and optimizes the stored procedure.
Code reuse: There is no need to write frequently used code again and again.
Improved security: Data security can be increased by allowing access only to the procedure.
Less network traffic: Instead of sending multiple SQL statements at once, only the procedure name and parameters are sent.

Using Stored Procedures in Hindi | Using Stored Procedures:

A stored procedure is defined in SQL Server and is called using the EXEC command.

How to Create Stored Procedures? How to create a stored procedure?

A stored procedure is created using the CREATE PROCEDURE command.

Syntax:

CREATE PROCEDURE Procedure_Name

BEGIN

-- SQL Statements

END

An example:

CREATE PROCEDURE GetAllEmployees

BEGIN

SELECT * FROM Employees;

END;

Executing a Stored Procedure in Hindi | Executing a Stored Procedure:

A stored procedure can be executed through SQL Server Management Studio (SSMS) or through code.
The EXEC or EXECUTE command is used to call it.

Example:

EXEC GetAllEmployees;

Sending Parameters to Stored Procedures in Hindi | Sending Parameters to a Stored Procedure:

It is possible to pass parameters in a stored procedure. Parameters can be of two types:

Input parameter: To receive data from the user.
Output parameter: To return a result.
Example: Procedure with an input parameter

CREATE PROCEDURE GetEmployeeByID

@EmployeeID INT

BEGIN

SELECT * FROM Employees WHERE ID = @EmployeeID;

END;

Executing:

EXEC GetEmployeeByID @EmployeeID = 101;
Using Stored Procedures in .NET with C#
To use a stored procedure in .NET, the SqlConnection, SqlCommand, and SqlDataReader classes are used.

Example:

using System;

using System.Data;

using System.Data.SqlClient;

class Program

{

static void Main()

{

string connectionString = "Server=YourServerName;Database=YourDatabaseName;Trusted_Connection=True;";

using (SqlConnection connection = new SqlConnection(connectionString))

{

try

{

connection.Open();

// Name of the stored procedure

string procedureName = "GetEmployeeByID";

using (SqlCommand command = new SqlCommand(procedureName, connection))

{

command.CommandType = CommandType.StoredProcedure;

// Sending parameters

command.Parameters.Add(new SqlParameter("@EmployeeID", SqlDbType.Int)).Value = 101;

// Reading data

using (SqlDataReader reader = command.ExecuteReader())

{

while (reader.Read())

{

Console.WriteLine($"ID: {reader["ID"]}, Name: {reader["Name"]}");

}

catch (Exception ex)

{

Console.WriteLine($"Error: {ex.Message}");

}

With the above example, you can easily implement stored procedures in your projects.
