How can you use GlideRecord in ServiceNow to query records from a table? Explain its basic syntax, key methods like addQuery(), addEncodedQuery(), and next(), and provide an example of retrieving specific records based on conditions. How does GlideRecord differ from standard SQL queries in databases?

In ServiceNow, GlideRecord is used to query records from tables. Here’s how you can use it:

var gr = new GlideRecord('incident');  
gr.addQuery('priority', '1');  
gr.query();  

while (gr.next()) {  
    gs.info(gr.number);  
}

This retrieves all high-priority incidents. Dev Technosys provides expert Hire developers in USA for seamless implementations.
