How to duplicate a GlideRecord on ServiceNow

servicenowWhile working on generating thousand of rows to stress my application on ServiceNow I figure a way to duplicate any GlideRecord.

It’s important to note that in my example I’m querying a table and duplicating each record, this method should work with any single GlideRecord.

For the sake of simplicity here’s the code:

//query the rows we want to copy
var ga = new GlideRecord('cmdb_ci_server');
ga.query();

while (ga.next()) {
    //get all the fields for this record
    var fields = ga.getFields();
    //create a new record
    var gr = new GlideRecord('cmdb_ci_server');
    gr.initialize();
    for (var i = 0; i < fields.size(); i++) {
        var glideElement = fields.get(i);
        //make sure we don't copy the sys_id
        if(glideElement.getName() != 'sys_id')
        {
            gr[key] = ga.getValue(glideElement.getName());                  
        }
    }
    var newSysId = gr.insert();
};

    • True.
      There is a line missing (insert on line 13):

      var key = glideElement.getName();
      //make sure we don’t copy the sys_id

  2. This works for duplicating a record real well:

    var gr = new GlideRecord(‘myTableName’);
    gr.initialize();
    gr.get(current.sys_id);
    gr.insert();

    • For task records, you need to add gr.number = null after getting the copied record so that it doesn’t copy the number itself.

      var gr = new GlideRecord(‘myTableName’);
      gr.initialize();
      gr.get(current.sys_id);
      gr.number = null;
      gr.insert();

      • Here’s a better solution:

        var gr = new GlideRecord(‘myTableName’);
        gr.initialize();
        gr.get(current.sys_id);
        gr.number = new NumberManager(‘myTableName’).getNextObjNumberPadded();
        gr.insert();
