Example of using LINQ to SQL Database connection in Asp.Net

Step-1 :- Design Page like this

Source Code :-

---------------------------------------

<title>On Click Events</title>

</head>

<body>

<div>

<tr>

<td>

NAME

</td>

<td>

<asp:TextBox ID="txtName" runat="server"></asp:TextBox>

</td>

</tr>

<tr>

<td>

Company

</td>

<td>

</td>

</tr>

<tr>

<td>

City

</td>

<td>

<asp:TextBox ID="txtCity" runat="server"></asp:TextBox>

</td>

</tr>

<tr>

<td></td><td><asp:Button ID="btnsave" Text="save" runat="server"

onclick="btnsave_Click" /></td>

---------------------------------------

Step-2 :- Create Table "tblEmp"

Source Code :-

---------------------------------------

Create Table tblEmp

(

ID int identity(1,1) primary key,

Name varchar(50),

Company varchar(50),

City varchar(50),

)

---------------------------------------

Step-3 :- Add DBML Class in Application

Step-4 :- After then drag table "tblEmp" on DBML Class

Step-5 :-then write code for the Button "btnSave"

and GridView "grv1"

Source Code :-

---------------------------------------

using System;

using System.Collections.Generic;

using System.Linq;

using System.Web;

using System.Web.UI;

using System.Web.UI.WebControls;

namespace JavaScriprt_Examples

{

public partial class firstPage : System.Web.UI.Page

{

protected void Page_Load(object sender, EventArgs e)

{

if (!IsPostBack)

{

ShowGrid();

}

EmpDataBaseDataContext _eDBobj = new EmpDataBaseDataContext();

protected void btnsave_Click(object sender, EventArgs e)

{

tblEmp tblEmpObj = new tblEmp();

tblEmpObj.Name = txtName.Text;

tblEmpObj.Company = txtCompany.Text;

tblEmpObj.City = txtCity.Text;

_eDBobj.tblEmps.InsertOnSubmit(tblEmpObj);

_eDBobj.SubmitChanges();

lblmsg.Visible = true;

lblmsg.Text = "Add Successfully";

clearform();

}

protected void clearform()

{

txtName.Text = "";

txtCompany.Text = "";

txtCity.Text = "";

}

protected void ShowGrid()

{

var v = from m in _eDBobj.tblEmps select m;

grv1.DataSource = v;

grv1.DataBind();

}

In SQL function is a Stored Program that you can pass parameters into and returns a value.

A function must always return a value & but a procedure may or may not return a value.

Example :- (Return a single value from a Customer Table.)
------------------------------------------------
Create table Customer
(
SrNo int identity(1,1) primary key,
Name Varchar(50),
Age varchar(50),
ContactNo varchar(50)
)
------------------------------------------------

Create Function
----------------------------------------------

Create FUNCTION FUN1
(
-- Add the parameters for the function here
@id int
)
returns varchar(50)
as
BEGIN

-- Declare the return variable here
DECLARE @Name varchar(50)

-- Add the T-SQL statements to compute the return value here
SELECT @name=Name from Customer WHERE SrNo= @id

-- Return the result of the function
Return @name

END
----------------------------------------------

Execute Function
----------------------------------------------
select dbo.fun1(1)
----------------------------------------------

Ternary Operator in C#

Ternary operator:-

The Ternary operator is not a type of conditional statement but it is also used to check the conditions. It returns only one value based on conditions. Use the ternary operator to check many values in a single line of coding.

Syntax:-

Variable = condition ? True Part : False Part;

Conditional Operator:-

The conditional operator (?:) returns one of two values depending on the value of a Boolean expression. Following is the syntax for the conditional operator.

Syntax:-

Variable = condition ? first_expression : second_expression;

Source Code :-

static void Main(string[] args)

{

int a, b, Value;

a = 100;

b = 50;

Value = a > b ? a : b ;

Console.WriteLine("Greater Value:" + Value);

Console.Read();

}

Output:-

Greater Value:100

Continue and Break Statement in C# (Console Application)

--------------------------------------------------------------------------------------------------------------------------

Difference b/w Continue and Break statement :-

Continue statement :- A Continue statement jumps out of the current loop condition and jumps back to the starting of the loop code.

Break statement :- A Break statement breaks out of the loop at the current point or we can say that it terminates the loop condition.

----------------------------------------------------------------------------------------------------------------------------------

Source Code :-

using System;

using System.Collections.Generic;

using System.Linq;

using System.Text;

namespace Continue_Break_Prog

{

class Program

{

static void Main(string[] args)

{

int x;

for (x = 0; x <= 10; x++)

{

if (x == 5)

continue;

if (x == 8)

break;

Console.WriteLine("Number =" + x);

}

Console.ReadLine();

}

Result :-

Number = 0

Number = 1

Number = 2

Number = 3

Number = 4

Number = 6

Number = 7

Stored Procedures in Sql

"A Stored Procedures is a group of SQL Statements that has been Created and Stored in the database."

............................................................................................................

Advantage :-

Better performance
Less Traffic
Security
Integrity
Code-Reuseblity

Disadvantage :-

Work with Same Database

............................................................................................................

Design a database like this image :-

---------------------------------------------------------------------------------------------------------

Create a Table "Student"

Create table Student ( RollNo int primary key, Name nvarchar(50), MobileNo nvarchar(50), dob nvarchar(50) )

-------------------------------------------------------------------------------------------------------

Create a Stored Procedures..........................

A Single Stored Procedures for multiple Query Insert,Update,Delete, & Select .. i.e. SP_Query

-------------------------------------------------------------------------------------------------------------------------

Create proc SP_Query

@op nvarchar(50)='g',

@RollNo int=0,

@Name nvarchar(50)=null,

@MobileNo nvarchar(50)=null,

@dob nvarchar(50)=''

begin

if @op='insert'

begin

insert into Student values(@RollNo,@Name,@MobileNo,@dob)

end

if @op='update'

begin

update Student set

Name=@Name,

MobileNo=@MobileNo,

dob=@dob

where RollNo=@RollNo

end

if @op='delete'

begin

delete from Student where RollNo=@RollNo

end

if @op='select'

begin

select * from Student where RollNo=@RollNo

end

else

begin

select * from Student

end

--------------------------------------------------------------------------------------------------------------------------

Execute a Stored Procedures..........................

1. executing procedure for insert the data in Student table

exec SP_Query 'insert',3,'Mr. VICKY','09654388184','02-03-1993'

2. executing procedure for updating data in Student table

exec SP_Query 'update',2,'Mr. Vijay','08826439190','11-Oct-1993'

3. executing procedure for select data in Student table

exec SP_Query 'select',1

4. executing procedure for delete data in Student table

exec SP_Query 'delete',4

5. executing default procedure for Student table

exec SP_Query
