What is getRefRecord? ›

getRefRecord() returns a GlideRecord object for a given reference element. This is used widely in business rule scripts but incorrect usage of this can cause some major issues. This will explain you some issues seen and the best practice to follow to avoid these.

getReference gets the record used in another reference field. For example you have the Caller ID (reference to the sys_user table) and with getReference, you will retrieve the User record and save this as a gliderecord into a variable.

getReference() method requests the whole Record (one Object with all fields values) to the server. It may cause slowness to your Client Side action. Many cases one or very few fields are necessary for us. So, instead of getReference we can use GlideAjax.

The GlideRecord class is the way to interact with the ServiceNow database from a script. See the GlideRecord API reference for a complete list of methods. GlideRecord interactions start with a database query. The generalized strategy is: Create a GlideRecord object for the table of interest.

While it is easy to add multiple addQuery methods to our GlideRecord object, we need to add the OR condition in one of the existing addQuery method's object, as shown here: var gr = new GlideRecord('incident'); var qc = gr. addQuery('category', 'network'); qc.

g_scratchpad is sent once when a form is loaded (information is pushed from the server to the client), whereas GlideAjax is dynamically triggered when the client requests information from the server. If you're using getReference you will get ALL data for each record you "get" whether you need it or not.

getReference returns the GlideRecord of specified field and getValue() returns the current value of field. We use getReference on Reference fields to access the values of referenced tables.

The getDisplayValue() method is used when you need to retrieve the display value of a field. This is particularly useful when you want to display the value of a field as it appears to the user on the form, including any formatting or translations.

Using setWorkflow(false) prevents any related Business Rules from running as a result of your script. In many instances you want them to run, removing related records is one good example, in other cases you want the script to not affect anything else and you would want to use it.

For example: addQuery('priority', '=', '1') would filter records where the 'priority' field is equal to 1. addEncodedQuery: This method allows you to provide a pre-built encoded query string. An encoded query string is a URL-encoded string representing a query condition.

When a record field is updated with NULL value instead of (empty string), a before business rule that evaluates if the value is empty by calling the . nil() method will return false. The expected result is true because an empty value is written to the database.
