Hi @vinod6 ,

If you want to update the records you can use next() method

next() - goes to every record

hasNext() - tells whether there is record satisfying the query

_next() - used when your table field/column name as "name".

Thanks,

Danish

@vinod6 Here is answer to your question with example.

• hasNext()
  Determines if there are any more records in the GlideRecord.

var now_GR = new GlideRecord('kb_knowledge');
now_GR.query();
if (now_GR.hasNext()) {
  gs.info('Record found'); // found it, do it
} else {
  gs.info('Record not found'); // didn't find it
}

• _next()
  Moves to the next record in the GlideRecord. Provides the same functionality as next(), intended to be used in cases where the GlideRecord has a column named next.

var rec = new GlideRecord('sys_template');
rec.query();
while (rec._next()) { 
  gs.print(rec.number + ' exists');
}
