ServiceNow GlideRecord: initialize versus newRecord

initialize documentation > Creates an empty record within the current GlideRecord that is suitable for population before an insert

sNewRecord=true before insert, is populated before .insert()

in a nutshell,
isNewRecord() allows you to query values / perform validation before the insert (e.g. if you wanted to include conditions) and populates the records holding the values in memory
in the rare case for example you wanted to create/update a related record (e.g. in a custom table) BEFORE the insert operation, newRecord() enables values to be referenced


var gr=new record ('incident)';

gr.initialize() / gr.newRecord()




from Chuck Tomasi in this article,


  • initialize(): Creates an empty record suitable for population before an insert.
  • newRecord(); Creates a GlideRecord, set the default values for the fields and assign a unique id to the record.

Try these two in scripts background and you'll see that initialize gives no value to opened_at, whereas newRecord does.

var inc = new GlideRecord('incident');



var inc = new GlideRecord('incident');



I have always trusted newRecord more since learning about this a few years ago."

ServiceNow check for null or nil or empty (or not)

Haven't tested these all recently within global/local scopes, so feel free to have a play! option 1 use an encoded query embedded in the GlideRecord , e.g.  var grProf = new GlideRecord ( 'x_cls_clear_skye_i_profile' ); grProf . addQuery ( 'status=1^ owner=NULL ' ); grProf . query (); even better use the glideRecord  addNotNullQuery or addNullQuery option 2 JSUtil.nil / notNil (this might be the most powerful. See this link ) example: if ( current . operation () == 'insert' && JSUtil . notNil ( current . parent ) && ! current . work_effort . nil ())  option 3 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 can use gs.nil : var grAppr = new GlideRecord ( 'sysapproval_approver' ); var grUser = new GlideRecord ( 'sys_user' ); if ( grUser . get ( 'sys_id' , current . approver )){

Get URL Parameter - server side script (portal or classic UI)

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 ); }
