is there a removeQuery, changeQuery, or other way to manipulate a query in a business rule?

[akaupisch]

So the reason I'm doing this is to get around a bug in servicenow. The issue involves Resource Workbench and it overwriting my date with their hard coded default date.

My Business Rule:

When: Before

Query: true (the rest false)

No filter conditions

Advanced: true

under the Advanced Tab, Script:

(function executeRule(current, previous /*null when async*/) {
   try {
             if (current.getTableName() == 'roster_schedule_span')
                       return;
             var map = gs.action.getGlideURI().getMap();
             var referringProcessor = map.get('sysparm_processor');
             if (JSUtil.notNil(referringProcessor)) {
                       if (referringProcessor.toString().indexOf("com.snc.resource_management") > -1)
                                 current.addQuery("show_as", "!=", "on_call"); // another bug fix that we have....sigh
                       else if (referringProcessor.toString().indexOf('ResourceWorkbenchService') > -1) {
                                 /* This is a total hack to get around 2 bugs with ResourceWorkbench
                                 * Bug 1: They hard code the default view to be 12 months -1 day from today
                                 * Bug 2: If you set the EndDate prior to selecting the Group, it 
                                 *               automatically overrides your date with their default 12
                                 *               months - 1 day. 
                                 * As such, we check to see if the end date is exactly 1 year - 1 day 
                                 *     from today. If it is, then we default to 3 months out
                                 */
                                 var endDate = new GlideDateTime(map.get('sysparm_end_date').toString());
                                 var defaultDate = new GlideDateTime();
                                 defaultDate.addYears(1);
                                 defaultDate.addDays(-1);
                                 if (defaultDate.equals(endDate))
                                           ;// !!!!!!! this is where I'd like to remove the end_date part of the query and instead
                                             // default to a different date something like current.changeQuery('end_date', myDefaultDate);
                         }
               }
   }
   catch(ex)
   {
             gs.error('Schedules Exception:\r\n' + ex );
   }
})(current, previous);

Check below the 'if (defaultDate.equals...)' statement, that's where I'd like to override/change this query.

The best you can probably do is use .addOrCondition() with your date query.

There is no API to change or remove an existing query without re-initializing current.

[akaupisch]

the or condition wont work as it'll include the dates we don't want. I like the idea of re-init, but is there a way to grab the original conditions before you re-init?

[drjohnchun]

You might try

var oldQuery = current.getEncodedQuery();   // returns an Encoded Query String with all queries added to current so far
var newQuery = oldQuery.replace(defaultDate, myDate);   // use RegEx to match defaultDate
current.initialize();
current.addQuery(newQuery);
