What are good ADO.NET object(s) to replace the ADO Recordset object?

The differences includes

In ADO, the in-memory representation of data is the recordset.

In ADO.net, it is the dataset

A recordset looks like a single table in ADO

In contrast, a dataset is a collection of one or more tables in ADO.net

ADO is designed primarily for connected accessADO.net the disconnected access to the database is used

In ADO you communicate with the database by making calls to an OLE DB provider.

In ADO.NET you communicate with the database through a data adapter (an OleDbDataAdapter,

SqlDataAdapter, OdbcDataAdapter, or OracleDataAdapter object), which makes calls to an OLE

DB provider or the APIs provided by the underlying data source.

In ADO you cant update the database from the recordset. ADO.NET the data adapter allows you

to control how the changes to the dataset are transmitted to the database.

How do you declare a static variable and what is its lifetime? Give an example.

Answer1static int MyintThe life time is during the entire application.

br> Answer2

The static modifier is used to declare a static member, which belongs to the type itself rather

than to a specific object. The static modifier can be used with fields, methods, properties,

operators, events and constructors, but cannot be used with indexers, destructors, or types. In

C#, the static keyword indicates a class variable. In VB, the equivalent keyword is Shared. Its

scoped to the class in which it occurs.

Example

a. Static int var //in c#.net

b. static void Time( ) //in c#.net

How do you separate business logic while creating an ASP.NET application?

There are two level of asp.net debugging

1. Page level debugging

For this we have to edit the page level debugging enable the trace to true in the line in the html

format of the page.%@ Page Language=vb trace=trueAutoEventWireup=false

Enable trace enabled=true.

If there is a calendar control to be included in each page of your application, and and we do not

intend to use the Microsoft-provided calendar control, how do you develop it? Do you copy and

paste the code into each and every page of your application?

Create the Calendar User Control

The control we will create will contain a calendar control and a label which has the correspondingdate and time written

Steps are:-

Creating a CalenderControl

1) To begin, open Visual Studio .NET and begin a new C# Windows Control Library.

2) You may name it whatever you like, for this sample the project name will be CalenderControl

Using the Calender Control in a Windows Application

Its just like adding any other control like a button or a label.

1) First, create a new Windows Application project named: CustomControl.

2) Add a reference to the Calender Control DLL named: CalenderControl.dll.

3) Now you a can customize the Toolbox:

Right-Click the Toolbox> .NET Framework Components> Browse> select the

CalenderControl.dll.

4)The Calender Control is now added to the Toolbox and can be inserted in Windows Form as

any other control. The control itself will take care of the date display

Which command using Query Analyzer will give you the version of SQL Server and

Operating System?

@@VERSION

Returns version, processor architecture, build date, and operating system for the current

installation of SQL Server.

How to find the SQL server version from Query Analyser

Answer1

To determine which version of Microsoft SQL Server 2005 is running, connect to SQL Server

2005 by using SQL Server Management Studio, and then run the following Transact-SQL

statement:

SELECT SERVERPROPERTY(productversion), SERVERPROPERTY (productlevel),

SERVERPROPERTY (edition)

The results are:

The product version (for example, 9.00.1399.06?)

. The product level (for example, RTM). The edition (for example, Enterprise Edition).

For example, the result looks similar to:

9.00.1399.06 RTM Enterprise Edition

How to determine which version of SQL Server 2000 is running

To determine which version of SQL Server 2000 is running, connect to SQL Server 2000 by

using Query Analyzer, and then run the following code:

SELECT SERVERPROPERTY(productversion), SERVERPROPERTY (productlevel),

SERVERPROPERTY (edition)


6/26

The results are:

The product version (for example, 8.00.534).

The product level (for example, RTM or SP2?).

The edition (for example, Standard Edition). For example, the result looks similar to

:

8.00.534 RTM Standard Edition

Answer2

One can also use SELECT @@Version where the result would look like

Microsoft SQL Server 2005 - 9.00.1399.06 (Intel X86)

Copyright (c) 1988-2005 Microsoft Corporation

Express Edition on Windows NT 5.1 (Build 2600: Service Pack 2)

Using query analyzer, name 3 ways you can get an accurate count of the number of

records in a table.

Answer1.

a. Select count(*) from table1

b. SELECT object_name(id) ,rowcnt FROM sysindexes WHERE indid IN (1,0) AND

OBJECTPROPERTY(id, IsUserTable) = 1c. exec sp_table_validation @table = authors

Answer2.

SELECT count( * ) as totalrecords FROM employee

This will display total records under the name totalrecords in the table employee

use COUNT_BIG

Returns the number of items in a group.

@@ROWCOUNT

Returns the number of rows affected by the last statement.

Use this statement after an SQL select * statement, to retrieve the total number of rows in the

table
