What is the use of get method in Glide record?
The ‘get’ method is used to return first record in the result set.
The ‘get’ method can also be used when you know the sys_id of that record. It returns Boolean values based on the result.
Example 1:
var grIncident=new GlideRecord('incident');
if(grIncident.get('9e7f9864532023004247ddeeff7b121f')){
gs.print('There exist incident with sys_id 9e7f9864532023004247ddeeff7b121f');
}else{
gs.print('There is no incident with sys_id 9e7f9864532023004247ddeeff7b121f');
}
Example 2:
var grIncident=new GlideRecord('incident');
if(grIncident.get('number','INC0000601')){
gs.print('There exist incident with number INC0000601');
}else{
gs.print('There is no incident with number INC0000601');

How can we update records without updating system fields like Updated, Created, etc. for a particular update?
The autoSysFields is used to disable the update of ‘sys’ fields (Updated, Created, etc.).
Example Script:
var gr = new GlideRecord('incident');
gr.addQuery('category', hardware);
gr.query();
while(gr.next()){
gr.autoSysFields(false);
gr.category = 'software';
gr.update();
}

What is the necessity of script action if we already have script include to write server side script?
Script Actions are executed asynchronously while Script Includes are executed synchronously.
If there is scenario where script execution is going to take longer time then it's always better to go with Script Actions as user don't need to wait for script execution completion.
