While you’re using the DELETE or UPDATE to change the data in any database like MySQL or ORACLE, the WHERE clause can be used to avoid inadvertently changing data everywhere.
<u>Explanation:</u>
The WHERE clause checks the condition and the changes mentioned by the DELETE or UPDATE command will be done if the condition is true. There are also other clauses like HAVING, IN which will have range either inclusive or exclusive.
It is also noted that in MySQL, there is a method called WorkBench which enables safe mode and doesn’t execute statements without the WHERE clause.

The Correct syntax for inserting an image as hyperlink is given in explanation section
Explanation:
To make an image act as a hyperlink, place the image element within the HTML anchor "<a></a>" element.
The syntax of inserting image hyperlink in XHTML is given below.
<a href = "link_that_can_be_accessible"><img src="source of image" alt="display name if image not shown in the browser" border="0"/></a>
for example lets insert image as hyperlink
<a href="ajax.html"><img src="logo.gif" alt="AJAX" border="0" /></a>
The default appearance is a blue border around the image. Specifying border="0" removes the border around the image.
if you want to insert image from another folder then the image hyperlink looks like this:
<a href="ajax.html"><img src="/images/html5/logo.gif" alt="AJAX" border="0" /></a>
If you want to insert image from another server then image hyper link looks like this:
<a href="ajax.html"><img src="https://www.myExample.com/images/html5/logo.gif" alt="AJAX" border="0" /></a>
