ASP.Net Example

we must add using System.Data.SqlClient; namespace. 

now following code you can use.

This is Vary old Techniques. If we use techniques with Asp.net 

there is Pooling required because if there is large amount of users

Insert into database using sqlcommand 

using System;
using System.Data;
using System.Data.SqlClient;

   class sqlcommandexample

{
      static void Main() 
      {

string CN="server=(local)\\SQLEXPRESS;database=DBTEST;Integrated Security=SSPI"; 

SqlConnection objCn = new SqlConnection(CN);
         SqlCommand objCmd= objCn.CreateCommand();

         try 
         {

objCn.Open();

objCmd.CommandText = "CREATE DATABASE NewDB";
Console.WriteLine(objCmd.CommandText);

objCmd.ExecuteNonQuery();
Console.WriteLine("Now is Database created and database");
objCn.ChangeDatabase("NewDB");

objCmd.CommandText = "CREATE TABLE aspdotnetTable(COL1 integer)";
Console.WriteLine(objCmd.CommandText);
Console.WriteLine("NO Rows Affected is: {0}", objCmd.ExecuteNonQuery());

objCmd.CommandText = "INSERT INTO aspdotnetTable VALUES (100)";
Console.WriteLine(objCmd.CommandText);
Console.WriteLine("NO Rows Affected is: {0}", objCmd.ExecuteNonQuery());
         
         } catch (SqlException ex) {
         
            Console.WriteLine(ex.ToString());
         
         } finally {  
         
            objCn.Close();
            Console.WriteLine("Connection Closed.");
         
         }
      }
