ServiceNow initialize vs newRecord | Servicenow tips and tricks | Sevicenow GlideRecord examples

Hi All,

Hope you are doing fine.
In this tutorial we will be looking into a basic question on ServiceNow glideRecord i.e. what is the difference between initialize and new record in ServiceNow.
First we will try to understand what is ServiceNow glideRecord ?
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.
– Build the query condition(s).
– Execute the query.
– Apply script logic to the records returned in the GlideRecord object.

Here is what the generalized strategy looks like in pseudo-code:

// 1. Create an object to store rows from a table
var myObj = new GlideRecord(‘table_name’);

// 2. Build query
myObj.addQuery(‘field_name’,’operator’,’value’);
myObj.addQuery(‘field_name’,’operator’,’value’);

// 3. Execute query
myObj.query();

// 4. Process returned records
while(myObj.next()){
//Logic you want to execute.
//Use myObj.field_name to reference record fields
}

What is servicenow gliderecord initialize ?
Creates an empty record within the current GlideRecord that is suitable for population before an insert.

What is servicenow gliderecord newRecord?
Creates a GlideRecord, sets the default values for the fields, and assigns a unique ID to the record.
