How is update function works in server side script

@praveensnow9984 

which update method you are referring?

GlideRecord update?

if yes then it simplys updated the record with the fields you set just before using the update() method

Hi @praveensnow9984,

In ServiceNow scripting, how the update() function works depends on the context you are using it in. There are two completely different types of "update" functions in ServiceNow server-side architecture: 

• gr.update() (GlideRecord API): Used to save record changes directly to the database.

• c.server.update() / server.update() (Service Portal API): Used to trigger a server-side refresh or pass data from a Service Portal widget's client controller to its server script.

If you find my answer useful, please mark it as helpful and correct. ‌‌😊

Hello @praveensnow9984 ,

The GlideRecord update() method is used in backend like Business Rules, Script Includes, and Background Scripts. It saves changes made to a record back into the database.

Calling .update() commits those adjustments directly to the ServiceNow database.

for ex :

// Example in a Background Script or Script Include
var gr = new GlideRecord('incident');
if (gr.get('sys_id_of_the_record')) { 
    gr.short_description = 'Updated via Server Script';
    gr.update(); //Commit and trigger system engines
}

Additionally we have c.server.update() : Service Portal Communication -

In Service Portal Widgets, c.server.update() is a client-side controller method that triggers execution of the widget's server-side script.
