Hi All,

I am new in Scripting can anyone explain me what the below 2 lines do?

var myObj = new GlideRecord('incident');

myObj.query(); //// -------??????

while(myObj.next()){----??????

[Aryan]

myObj.query(); 

while(myObj.next())

???

This line of code will check the complete records as there is no condition added and will return you all records which are there in the "incident" table. 
For example: If there are 1000 records, the while loop will return 1000 iterations inside the loop.

Thank you

The best way to check your code would be:

Run the same three line of code in the "Scripts - Background" module in your Servicenow instance.

var myObj = new GlideRecord('incident');

myObj.query(); //// -------??????

while(myObj.next()){
gs.info("Incident Row Count: "+myObj.number);
}
