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.).

gr.addQuery('category', hardware);
gr.query();
while(gr.next()){
gr.autoSysFields(false);
gr.category = 'software';
gr.update();
}
