use an encoded query embedded in the GlideRecord, e.g.

var grProf=new GlideRecord('x_cls_clear_skye_i_profile');

grProf.addQuery('status=1owner=NULL');

even better use the glideRecord addNotNullQuery or addNullQuery

(this might be the most powerful. See this link)

if (current.operation() == 'insert' && JSUtil.notNil(current.parent) && !current.work_effort.nil())

there might be times when you need to get inside the GlideRecord and perform the check there, for example if the code goes down 2 optional routes depending on null / not null

var grAppr=new GlideRecord('sysapproval_approver');

var grUser=new GlideRecord('sys_user');

if (grUser.get('sys_id', current.approver)){

if (!gs.nil(grUser.email)){

gs.addInfoMessage('resent approval to ' + grUser.email);

check if this works outside global scope!

var table_name = 'incident';

var field_name = 'u_interaction';

if (current_sys_id == undefined) current_sys_id = this.getParameter('sysparm_current_sys_id');

var record = this.getGlideRecord(table_name, field_name, current_sys_id);

use empty string, either within GlideRecord filter (for not null) or after the gr.next()

var gr=new GlideRecord('sys_user');

gr.addQuery('name', '!=', '');

var gr=new GlideRecord('sys_user');

gr.addQuery('active', true);

if (gr.getValue('name')==''){

Classic UI : var sURL_editparam = gs . action . getGlideURI (). getMap (). get ( ' sysparm_aparameter ' ); if ( sURL_editparam == 'true' ) { gs . addInfoMessage ( 'parameter passed ); } Portal : var sURL_editparam = $sp . getParameter ( " sysparm_aparameter " ); if ( sURL_editparam == 'true' ) { gs . addInfoMessage ( 'parameter passed ); }
