Query Builder #
The IQNOX Query Builder Widget is a powerful and intuitive tool designed to simplify complex query creation within the ThingWorx platform. Built on top of the popular jQuery QueryBuilder library, this widget provides a user-friendly, visual interface for building dynamic and nested queries without writing a single line of code.
Example
Usage #
The Query Builder Widget empowers both technical and non-technical users to:
- Build advanced queries for infotables or data services
- Filter large datasets efficiently based on dynamic criteria
- Accelerate development time by eliminating the need for manual query coding
- Enable end-users to customize filters in dashboards or reports directly
Properties #
| Properties | Type | Binding | Default | Description |
|---|---|---|---|---|

DataShapes
To utilize the query builder, it is required to create a datashape that defines the fields intended to be used and displayed by it.
To constrain the selectable options on a specific field, the corresponding row in the dataset must include an infotable within the column mapped to the ValuesField. This infotable is required to conform to the IQNOX_CommonDisplayValue_DS datashape, which defines the structure of the permissible values.
IQNOX_CommonDisplayValue_DS
value: STRING // actual value
display: STRING // text to show in the value dropdown
section: STRING // under what section should it be locatedBehavior
- If valid
Datais provided forvalues, the Dropdown will display these server-provided options. - If no matching entry is found in
Datafor a column, the dropdown will fall back to the default behavior – using input from the user.
Important notes
- Inserting a query programmatically that has more groups than allowed in
AllowGroupswill not register the entire query in the widget.
