Hi All,

I have 10 records only on whole table , now I want to update records So 

When do we use next(), hasNext() and _next()

Hi,

var gr=new GlideRecord('incident');

gr.addQuery('category','software');

gr.query();

if(gr.hasNext())

{

if(gr.next())

{

gr.description="ABC";

gr.update();

}

}

is it correct ? to check Query condition ?

[Upender Kumar]

Your code will run only once. To update all the records use below code

var gr=new GlideRecord('incident');
	gr.addQuery('category','software');
	gr.query();
	while(gr.next())
	{
		gr.description="ABC";
		gr.update();
	}
