This class provides methods to manage for managing the database in client-side scripts: auto auto population of the fields, displaying some form elements and setting mandatory attribute for them regarding the values set in the Reference Fields.

The SimpleRecord client class allows a user to manage both records in the tables and its fields.

In this class, client-side queries are executed on the server. That is, to get a record data, a request from the client side should be sent to the server.

The functionality of the client-side SimpleRecord class can be not enough for managing some business tasks. In this case, use the SimpleAjax class or Table API.

addQuery()

Use this method to filter the records by specifying certain conditions (field, operator, value). You can also add a condition to get records with a field equal to the value, or that is in the list?

Within this method, it is possible to use any preferred condition operator. Notice that it is necessary to use the system name of the operator in the script.

Code Block

language	js
theme	Eclipse
title	addQuery
linenumbers	true

const record = new SimpleRecord('task');
record.addQuery('number', 'like', 'TSK');
record.addQuery('subject', 'startswith', 'Email');
record.query(() => {
    while (record.next()) {

function callback(response) {
    const answer = response.responseXML.documentElement.getAttribute('answer');
