👉Pattern Matching

✅LIKE Predicate

The LIKE predicate allows the comparison of one string value with another string value, which is not identical.

Wildcard Characters:
% allows matching any string of any length.
_  allows matching on a single character.


✅IN and NOT IN predicate

If a value needs to be compared to a list of values, then the IN predicate is used.

NOT IN is used to select all the rows where values do not match the values in the list.

   👉 Javascript with OOPs (Inheritance) In Javascript, Inheritance is done using prototype object. A prototype object is an object pointing to another object. We don't have a direct inheritance in Javascript, we can mimic inheritance using prototype. Let's say, we have one more class that inherits from Customer, and it submits to Server2. function CustomerChild(){         this.submit = function() {         alert ("this submits the data to Server2" + " "      +  this.CustomerName + " "                                       + this.CustomerCode");   }}             CustomerChild.prototype = new Customer(); var cust = new Customer(); cust.CustomerName ("John"); cust.Submit();  --this is a call to the submit method of the Customer class.  cust = new CustomerChild(); cust...

Javascript-Unobtrusive - (6)

  👉 Unobtrusive Javascript In web pages, we have presentation and behavior. Presentation is controlled by HTML and behavior is controlled by javascript. <input type = "button" onclick = "Fun1();" id = btn1/> <script language = javascript>              Function Fun1()                       {alert ("Hi");} </script> Here, button is tightly linked with the behavior. Unobtrusive javascript seperates presentation from behavior, making HTML more sleek. <input type = "button"  id = btn1/> <script src = "jscript1.js" type = "text/ javascript"> </script> code of jscript1.js file: <script language = "javascript">            Function Fun1() {                      alert("Hi");             } var e1 = document.getElementByID("btn1"); e1.onclick = ...
