ServiceNow GlideRecord VS GlideRecordSecure

 https://developer.servicenow.com/blog.do?p=/post/gliderecord-vs-gliderecordsecure/

GlideRecord performs get/create/update operations to DB without concern of permission. 

Best practice is to call  canRead(), canWrite(), canDelete() and canCreate() functions when need permission

GlideRecordSecure checks permisssion on its on before performing get/create/update operations to DB 

GlideRecord Query with Access Check

var catSysIds = getCatSysIds();

function getCatSysIds() {
    var cats = [];

    var catData = new GlideRecord("x_abc_britt_app.cat_data");
    catData.query();

    while (catData.next()) {
        if (!catData.canRead()) {
            continue;
        }
        cats.push(catData.getUniqueValue());
    }

    return cats;
}

GlideRecordSecure Query (Access Check Built In)

var catSysIds = getCatSysIds();

function getCatSysIds() {
    var cats = [];

    var catData = new GlideRecordSecure("x_abc_britt_app.cat_data");
    catData.query();

    while (catData.next()) {
        cats.push(catData.getUniqueValue());
    }

    return cats;
}
