General Recommendations

  • Create constants with meaningful names.

  • To speed up the selection, use the selectAttributes() method of the SimpleRecord class.

    The following example generates an array that contains the record IDs:

    selectAttributes
    const user = new SimpleRecord('user');
    user.addQuery('email', 'like', '@bestcompany');
    user.selectAttributes('sys_id'); // select sys_id only
    user.query();
    const userIDs = [];
    while (user.next()) {
    userIDs.push(user.sys_id);
    }
  • Use operators in/not in for building conditions:

    is one of in query
    const tableIds = [
    '156950363112415683',
    '156950616617772294',
    '155931135900000083',
    current.getValue('child_table_id')
    ]
    const column = new SimpleRecord('sys_db_column');
    column.addQuery('table_id', 'in', tableIds);
    column.query();

    instead of multiple addOrCondition():

    addOrCondition
    const column = new SimpleRecord('sys_db_column');
    column.addQuery('table_id', current.getValue('child_table_id'));
    column.addOrCondition('table_id', '156950363112415683');
    column.addOrCondition('table_id', '156950616617772294');
    column.addOrCondition('table_id', '155931135900000083');
    column.query();
  • Add record count preview before the update/delete operation:

    updateMultiple
    const record = new SimpleRecord('sys_vcs_preview_log');
    record.addQuery('retrieved_pack_id', current.sys_id);
    record.addQuery('state', 'skipped');
    record.addQuery('error_text', 'The system has a newer record');
    record.query();
    ss.addInfoMessage(`Correction for ${record.getRowCount()} objects`);
    record.setMultipleValue('state', 'good');
    //record.updateMultiple();
    deleteMultiple
    const record = new SimpleRecord('imp_ldap_users');
    record.addEncodedQuery('imp_company%3DSofaShop.ru^sys_created_atLIKE2019-');
    record.query();
    ss.addInfoMessage(record.getRowCount());
    //current.deleteMultiple();
  • The script that creates the record and its related records (for example, a Task record and child records of the tasks) must check a root record creation before the related records are created:

    const recordTask = new SimpleRecord('task');
    //recordTask.subject = 'Main Task';
    const insertedID = recordTask.insert(); // ID of inserted record OR 0

    const activities = [
    'Analysis',
    'Coding',
    'Review',
    'Testing',
    'Merging',
    'Release'
    ];

    if (insertedID != 0) { // if Task created than create related tasks
    const subtasksID = [];
    activities.forEach(activityName => {
    const subTaskRecord = new SimpleRecord('task');
    subTaskRecord.parent_id = insertedID;
    subTaskRecord.subject = activityName;
    subtasksID.push(subTaskRecord.insert());
    });
    } else {
    ss.addErrorMessage(JSON.stringify(recordTask.getErrors()));
    }
  • Comment your code when you use the Choice attributes in your scripts:

    Adding comments
    if (current.stage == '4' || current.stage == '6') { // Canceled OR Completed
    const start = new SimpleDateTime(current.start_time);
    //...
  • Use the getAttributes() method to check an object before inserting or updating:

    const task = new SimpleRecord('task');
    task.initialize();
    ss.info(JSON.stringify(task.getAttributes(), null, 2));
    /* Info: {
    "sys_id": "",
    "parent_id": "",
    "assigned_user": "",
    "number": "",
    "short_description": "",
    "active": 1,
    ...
    */

    This method also checks whether an object has a specified attribute or not before calling:

    getAttributes
    if (task.getAttributes()['has_breached'] != undefined) {
    task.has_breached = true; // SLA Breached
    task.update();
    }
  • Use the source messages as an argument:

    Source Message as an argument
    ss.addInfoMessage('The protocol was send on email');
    // Source Message and Message was previously added

    instead of message preparing:

    Message preparing
    const sm = new SimpleMessage();
    const localizedMessage = sm.getMessage('The protocol was send on email');
    ss.addInfoMessage(localizedMessage);

    and instead of hardcode messaging:

    Hardcode messaging
    if (ss.getUser().language_id.language === 'en') {
    ss.addInfoMessage('The protocol was send on email');
    } else {
    ss.addInfoMessage('Протокол был отправлен на почту');
    }
