addNullQuery

Filters for records where a specific field is null. This is technically different than ISNOTEMPTY in a query. Basically, null is empty, but empty is not always null. A null field is usually produced by older records where a field may not have existed at the time.

Functionally, this just appends <fieldName>=NULL to the GlideRecord's internal encoded query.

Parameters:

• fieldName: String

Returns: String

Returns <fieldName>=NULL.

Mutates Self?

Yes, the gliderecord's internal encoded query will be modified.

Examples:

Script

//TODO: this is throwing error rn and I don't know why
var incidentGr = new GlideRecord('incident'); 
gs.print(incidentGr.addNullQuery('caller_id'));
gs.print(incidentGr.getEncodedQuery());
