How to get the record count in the while loop?

Rick54 · ‎03-18-2019

Hello,

I am trying to get the count of all record that matches the query condition. When I use the below script, the count is always being '1' even though there are 1+ records that matches the condition. I am I missing anything? Please suggest.

var count = 0;
var gr= new GlideAggregate('cmdb_ci_db_mssql_instance');
gr.addAggregate('COUNT');
gr.addQuery('sys_id', 'IN', instances);//This variable holds 1 or more record sys ids
gr.addQuery('install_status',7);
gr.query();
while(gr.next()){
	instanceCount = gr.getAggregate('COUNT');
	gs.print(instanceCount);
	
}

This time I have 2 records that matched the condition
Output:
*** Script: 0
*** Script: 1
*** Script: 1
*** Script: 0

Expected Ouput: 2

My expectation is that these records are queried one after one that's the reason I am getting individual record's count. Is there any way to count all looped records and combine and output as 2? Thanks

here we go

var count=0;
var rcount;
var gr = new GlideRecord('cmdb_rel_ci');
gr.addQuery('child.sys_id','d53a14fddbd8330080e0a08a48961902');
gr.query();
if(gr.next())
{
gs.print(gr.parent.getDisplayValue());
var gr2 = new GlideRecord('cmdb_rel_ci');
gr2.addQuery('parent.sys_id',gr.parent);

gr2.query();
rcount=gr2.getRowCount();
while(gr2.next())
{
if(gr2.child.install_status== 7){
count++;
//gs.print(gr2.child.install_status);
}
}

}

if(rcount == count)
{

gs.print('hey harsh please update the database');

}
else
{
gs.print('no need to update the database');
}

Thanks for your time on this Brian. I did the above and it gave me multiple records.

Can you do a gs.print(instances.toString().split(',')); to make sure it is giving us what we are expecting.

Brian, below is the complete question. I am stuck with a logic.

Something more like this.

var rel2 = new GlideRecord('cmdb_rel_ci');
rel2.addEncodedQuery("type=55c95bf6c0a8010e0118ec7056ebc54d^child.sys_class_name=cmdb_ci_db_mssql_instance^parent.sys_class_name=cmdb_ci_database^parent.sys_id="+db+"");//db variable holds one database record
rel2.query();
var instance = [];
while(rel2.next()){
	instances.push(rel2.child);
	var instCount = rel2.getRowCount();//this is giving me the correct count in this case 3 count
}

var inst = new GlideRecord('cmdb_ci_db_mssql_instance');
	inst.addQuery('sys_id', 'IN', instances);
	inst.addQuery('install_status', '7');
	inst.query();
	while(inst.next()){
		var instanceCount = inst.getRowCount();//always gives me 1 as count 
		if(instCount == instanceCount){
			
		//do something in this loop
		}
		
	}

Can you try running this is script background and see what it returns. You will need to put in the comma separated list of sys_id.

var inst = new GlideRecord('cmdb_ci_db_mssql_instance');
var i = 0;
inst.addQuery('sys_id', 'IN', 'sys_id1, sys_id2, sys_id3');
inst.addQuery('install_status', '7');
inst.query();
while(inst.next()){
	i ++;
	
}
gs.print(i);
