after execution of query . you can limit the number of records that your query will return.
eg:
if you will query of incident table to check how many active incident is available then you can simply write glide record then it will return you list of incidents number now you only want to 10 records rather than all incidents then in such scenario you will use setLimit();
var abc= new GlideRecord('incident');
abc.addActiveQuery();
abc.query();
while(abc.next())
{
gs.print(abc.number);
}
var abc= new GlideRecord('incident');
abc.addActiveQuery();
abc.setLimit(10);
abc.query();
while(abc.next())
{
gs.print(abc.number);
}
hope it will help you
