ServiceNow Function Fields for Database Transformations and Calculations


ServiceNow Function Fields for Database Transformations and Calculations


Create function fields and scripts in the Now Platform to perform common database transformations and calculations.

Regular fields store a value in the database. Instead of storing data, a function field displays the results of a database query. Function fields do not have an associated database column. Instead, function fields generate a value based on simple computations of other fields and constants. They can be used like any other fields in the system: in forms, lists, query conditions, reports, and so on.

Warning: A function field that references another function field in the function will result in an error. Function fields don't hold data or evaluate in run-time.

Example: Use case

You want to identify all incidents with a probably useless short description of fewer than 10 characters.

Instead of querying all records to determine which record meets a given criteria, create a function field or function script that retrieves only the records that meet the criteria.

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 ); }
