Sql Server Database Backup

iampriya — Sun, 29 Aug 2010 06:40:58 +0000

DECLARE @name VARCHAR(50) -- database name DECLARE @path VARCHAR(256) -- path for backup files DECLARE @fileName VARCHAR(256) -- filename for backup DECLARE @fileDate VARCHAR(20) -- used for file name


SET @path = 'C:\Backup\'
SELECT @fileDate = CONVERT(VARCHAR(20),GETDATE(),112)
DECLARE db_cursor CURSOR FOR

SELECT name

FROM master.dbo.sysdatabases

WHERE name NOT IN ('master','model','msdb','tempdb')
OPEN db_cursor

FETCH NEXT FROM db_cursor INTO @name
WHILE @@FETCH_STATUS = 0

BEGIN

Cursor Components

Based on the example above, cursors include these components:

DECLARE statements – Declare variables used in the code block
SET\SELECT statements – Initialize the variables to a specific value
DECLARE CURSOR statement – Populate the cursor with values that will be evaluated
- NOTE – There are an equal number of variables in the DECLARE CURSOR FOR statement as there are in the SELECT statement. This could be 1 or many variables and associated columns.
OPEN statement – Open the cursor to begin data processing
FETCH NEXT statements – Assign the specific values from the cursor to the variables
- NOTE – This logic is used for the initial population before the WHILE statement and then again during each loop in the process as a portion of the WHILE statement
WHILE statement – Condition to begin and continue data processing
BEGIN…END statement – Start and end of the code block
- NOTE – Based on the data processing multiple BEGIN…END statements can be used
Data processing – In this example, this logic is to backup a database to a specific path and file name, but this could be just about any DML or administrative logic
CLOSE statement – Releases the current data and associated locks, but permits the cursor to be re-opened
DEALLOCATE statement – Destroys the cursor

FloatingPoblem

iampriya — Wed, 18 Aug 2010 11:00:22 +0000

When we want to float a html control above the object control then we will not be able to float it by
increase the z-index property but it can be possible if we use both as object

DATA=’objNew.html’ style=’z-index:12; width:100%; position:absolute; height:5px;’
TYPE=’text/x-scriptlet’ >

In the above example in between object we fetch html and do needed coding there.

In other way it can also be possible by taking iframe instead of object

Howto run a query from mysql command prompt

We need to follow the following steps to run database query from mysql comand prompt
1>Go to Mysql comand promt.
2>Specify the connecting password.
3>Now create a sql file which we can use as source file to run all the query.
That is our comand will be =>
source (The sql file location where everything specified)
4>The sql file should be look like..

rnd_db_ddl.sql
drop database if exists rnd_db;

create database rnd_db;
use rnd_db;

\. C:/Projects/rnd_db/organization.sql=>this comand will execute the organization.sql
from the mention path.

Organization.sql should be look like this
organization.sql
drop table if exists organization;
create table `organization` (
`organization_id` int not null auto_increment,
`organization_name` varchar(200) not null,
`is_active` tinyint(1) not null,

How to use JSdoc

JSDoc is meant to do for Javascript, what Javadoc does for Java.

It does.

We can download and install JSDoc easily:

1. Download JSDoc
2. Expand the tgz.gz file (I use Winrar)
3. Optional – I copy the jsdoc folder to my D: drive to make things easier
4. Reminder – you need a perl runtime installed. ActivePerl is recommended
5. Open up a command prompt
6. Change to your JSDoc folder (mine is D:\JSDoc-1.10.2\)
7. Run it: “perl jsdoc.pl test.js” (to test it against the built in JS file)

JSDoc is like the following image

In the following all the parameter are showing..

ag Reference

The following is a summary of the supported tags (‘@’-attributes) that are supported by JSDoc. For actual examples of the usage of these tags, please see the test.js JavaScript file that is included in the JSDoc distribution.

@param	Provide information about a function parameter. A datatype indicator can be added between curly braces with this tag, as follows: /** * @param {String} paramName This is a string parameter */
@argument	Synonym for @param
@return	Provide information about the return value of a function.
@returns	Synonym for @return
@author	Provide information about the author of a JavaScript file or a function.
@deprecated	Signify that a function or class is deprecated, and should not be used if possible.
@see	Link to another class or function that is of importance to the current class or function. This tag can take several forms. To link to another method within the same class: @see #methodName To link to another class: @see ClassName To link to a specific method of another class: @see ClassName#methodName
@version	Show the version number of the current file or class
@requires	Define a dependency upon another class. The syntax for this tag is as follows: @requires OtherClassName This is text to be shown
@throws	Show that a method can throw a certain type of exception. The syntax for this tag is: @throws ExceptionType This is the label text
@exception	Synonym for @throws
@link	This is a powerful tag that can be used to link to a large number of other pages. It is also the only tag that can be used in the description text of a documentation string before the ‘@’-tag section. The usage is very similar to that of the @see tag, but the entire tag is wrapped in curly braces. For example: /** * This utility method is also a member of the {@link String} class, * in the form of the {@link String#utility} method. */
@fileoverview	This is a special-use tag. If the first block of documentation in a file starts with a @fileoverview tag, the rest of the documentation block will be used to provide a file overview in the documentation.
@class	This tag is used in a constructor’s documentation block to provide information about the actual class. The included documentation will then not be included in the constructor’s documentation.
@constructor	Signify that a function is the constructor for a class.
@type	Show the return type of a function. For example: /** * This function returns a String. * @return The name of the current user * @type String */
@extends	Used to show that a class is a subclass of another class. JSDoc is often quite good at picking this up on its own, but in some situations this tag is required.
@private	Signify that a function or class is private. Private classes and functions will not be available in the documentation unless JSDoc is run with the –private commandline option.
@final	Flag a value as being a final (constant) value.
@member	Show that a function is a member of a given class: /** * @member MyClass */ function SomeFunc(){ }
@ignore	Tell JSDoc to totally ignore this method.
@base	Force JSDoc to view the current class constructor as a subclass of the class given as the value to this tag: /** * This is a subclass of Shape * @constructor * @base Shape */ function Circle(){ // ... }
@addon	Mark a function as being an “addon” to a core JavaScript function that isn’t defined within your own sources, as shown below: /** * This is an addon function to SomeCoreClass which is * not defined within our own sources. * @addon */ SomeCoreClass.someFunction = function(){ // ... }
@exec	*Experimental!* Force JSDoc to “execute” this method as part of its preprocessing step, in the same way that class contructors are executed. This can allow attributes to be added to a class from within a function.

Security Issues

iampriya — Sat, 13 Feb 2010 07:58:29 +0000

Security Issues with ViewState

ViewState in ASP.NET can easily be tampered cause the ViewState data is not encrypted. Therefore, please do not store important data or information in ViewState. But if you really need to store the important data in Viewstate, few steps can be used to protect and encrypt the ViewState Data.
1. Enable ViewState Mac in page directives or in the web.config level

<%@Page EnableViewStateMAC=true %>

2. Set the machine.config key by using validation such as 3Des or Sha1. Sha1 is more secured compare to 3Des as it produces a larger hash than MD5 and is cryptographically stronger.

You need to edit your machine.config files like this.

<machineKey validation="3Des" validationKey="AutoGenerate,IsolateApps"/> or
<machineKey validation="SHA1" validationKey="AutoGenerate,IsolateApps"/>

If you are running WebFarm on your machine, you cannot use AutoGenerate in your validationKey, hence you must set the same key for all your web farm machine. Otherwise, ViewState generated from one machine could not be POSTed back to a machine farm with different key!. The keys should be 128 characters long(the maximum) and generated totally by random means.

Create XMl

iampriya — Sat, 13 Feb 2010 07:53:02 +0000

How to create xml

To create xml we need to do following steps=>

1)First include the name i)System.Xml ii)System.IO iii)System.Text.

2)create writer object

>XmlTextWriter writer = new XmlTextWriter(Server.MapPath(“xml/userInfo.xml”), Encoding.UTF8);

In Server.MapPath we specify the path where we would like to create xml file.

statr to write by writer.WriteStartDocument();

writer.WriteStartElement(“userInfo”); this specify strat element with element userInfo

writer.WriteElementString(“urlReferrer”, “none”);this specify sub element with element urlReferrer and value none

writer.WriteAttributeString(“timeVisited”, DateTime.Now.ToString());this specify a element attribute with timeVisited

writer.WriteEndElement(); this specify end of a element

writer.WriteEndDocument(); this specify end of a document.

writer.Close(); this specify close of a document.

Store Procedure example

CREATE PROCEDURE [dbo].[test_sp_add_user]
AS

DECLARE @UserPKID BIGINT

INSERT INTO test_user
(FirstName,LastName,Address1,Address2,
Country,EmailID,Password,Status)
VALUES
(@FirstName,@LastName,@Address1,@Address2,
@Country,@EmailID,@Password,@Status)

SET @UserPKID = @@identity
GO

(
@FirstName VARCHAR(255),
@LastName VARCHAR(255),
@Address1 VARCHAR(255),
@Address2 VARCHAR(255),
@Country VARCHAR(255),

@Password VARCHAR(255),
@Status BIT
)

CREATE PROCEDURE [dbo].[test_sp_delete_user]

GO

Add the following code to the section to redirect the user to a custom page:

This setting goes in your web.config file. It affects the entire application, though… I don’t think you can set it per page.

“xxx” is in KB. The default is 4096 (= 4 MB).

Cursor

iampriya — Mon, 02 Nov 2009 12:31:35 +0000

Cursors can be considers as result sets which allow a user to move through each record one by one.
Whenever we find some situation where we need to process each record individually we can use cursors.

In order to work with a cursor we need to perform some steps in the following order

1. Declare cursor
2. Open cursor
3. Fetch row from the cursor
4. Process fetched row
5. Close cursor
6. Deallocate cursor

First of all we need to declare a cursor with the help of Declare statement and in
order to specify the result set contained by this cursor we use Select statement.
For example we can define a cursor named “MyCur” and we can use a table named Users
having two columns UserName, and Password.

Declare MyCur Cursor
For
Select * From Users

Open MyCur

Now, fetch first row from this cursor and loop through the cursor records until the specified criteria is found

Declare @UserName Varchar(50)

Declare @Password Varchar(50)

Fetch Next From Cursor Into @UserName, @Password

While @@Fetch_Status = 0

Begin

–Check if appropriate row was found then process it

–Othewise

–Fetch the next row as we did in the previous fetch statement

End

When we have worked with the cursor, we’ll close it and deallocate it so that there will remain no reference to this cursor any more.

Close MyCur
Deallocate MyCur
