"< noscript >...< /noscript >" in JAVASCRIPT

-
It also known as  "Javascript Fallback Content "  People can turn Javascript off in their browser software which can cause your document to appear broken or incomplete to them if you are using Javascript to render content in any way. There are also situations in which automated software is attempting to index your document's content and it may not be able to process Javascript. HTML sports a Javascript content fallback feature in which anyone without Javascript enabled will be served up your alternate content, while regular users see the Javascript enabled content. This is done using the <noscript> element of HTML. If the user has Javascript enabled the <script> element will process while the <noscript> element is completely ignored. If the user does not have Javascript enabled the <script> element gets ignored, and the <noscript> element will process. Example : < head runat ="server"> < title ></ title...

nav element in HTML5

-
Like <header> , <nav> is a section element with a clear purpose. I have it on the left on this site though it's often placed horizontally above or below the header. Technically you can place it (or them – there can be more than one) anywhere you want, but remember never make it difficult for visitors. One of the most common mistakes beginners – and for that matter, many professionals – make is to not make navigation simple, straight forward and intuitive . The <nav> element is for "major navigation blocks" * . It can go in the header or article tags (which we will look at next); or it can be on its own. On the left I have it on its own and in the article element the "previous" and "next" links are in nav tags. Example  : <!DOCTYPE html> <html> <body> <nav> <a href="/html/">HTML</a> | <a href="/html5/">HTML5</a> | <a href="/css/">CSS...

HOW TO USE THEAD , TBODY , TFOOT IN HTML

-
Image
DESCCRIPTION : The <tbody> tag is used to group the body content in an HTML table. The <tbody> element is used in conjunction with the < thead > and < tfoot > elements to specify each part of a table (body, header, footer). Browsers can use these elements to enable scrolling of the table body independently of the header and footer. Also, when printing a large table that spans multiple pages, these elements can enable the table header and footer to be printed at the top and bottom of each page. The <tbody> tag must be used in the following context: As a child of a <table> element, after any <caption>, <colgroup>, and <thead> elements. EXAMPLE : <table border="1">   <thead>     <tr>       <th>NIHAR </th>       <th>BLOG</th>     </tr>   </thead>   <tfoot>   ...

Difference between == and === in JAVASCRIPT / PHP

-
=== and !== are strict comparison operators: JavaScript has both strict and type-converting equality comparison. For strict equality the objects being compared must have the same type and: Two strings are strictly equal when they have the same sequence of characters, same length, and same characters in corresponding positions. Two numbers are strictly equal when they are numerically equal (have the same number value). NaN is not equal to anything, including NaN. Positive and negative zeros are equal to one another. Two Boolean operands are strictly equal if both are true or both are false. Two objects are strictly equal if they refer to the same Object. Null and Undefined types are == (but not ===). Example :                0 == false   // true                  1 === "1"     // false, because they are of a di...

How the ALL keyword works in oracle

-
Multiset operators combine the results of two nested tables into a single nested table. The examples related to multiset operators require that two nested tables be created and loaded with data as follows: First, make a copy of the oe.customers table called customers_demo . We will add the nested table columns to customers_demo . CREATE TABLE customers_demo AS SELECT * FROM customers; Simple Example : Condition               Equivalent expression x > ALL  ( 1 ,  2 )           x >  2 x < ALL  ( 1 ,  2 )           x <  1 x = ALL  ( 1 ,  2 )          ( x =  1 )  AND  ( x =  2 ) x <> ALL  ( 1 ,  2 ) ...

Importing MS Excel data to SQL Server 2008

-
Image
The Import and Export Wizard The import and export wizard was available even with SQL 2000 has remained an important tool for exporting from and importing into SQL Server data from many different kinds of data sources. It can also be used for transferring data between non-Microsoft data sources. In this article, an example of transferring an MS Excel spreadsheet data to SQL Server 2008 is described. In any of the transformations it is important to realize that data types used in data sources are not exactly the same and that there are differences to be reckoned with. The basic steps to take are to indicate the source of data and the destination to which it needs to be transferred. In order to match the differences some mappings may be necessary if the source and destination are not both SQL Servers. The MS Excel file PrincetonTemp.xls used in this example is a simple spread sheet data that shows the temperature variations during a year and the maximum recorded temperature. The data...

-
Method 1 : INSERT INTO SELECT This method is used when table is already created in the database earlier and data is to be inserted into this table from another table.
