Overview
The Dataset module offers powerful configuration options for managing queries efficiently. Users can define queries with custom names, select database configurations, and input SQL statements, including tag embedding. Mapping options enable data population from query results, and users can specify time references (UTC or Local) for DateTime fields.
Additionally, the Dataset module allows users to display query results using DataGrids in screens and dashboards, simplifying data visualization. Query results can also trigger actions in custom scripts and tags, enhancing automation capabilities for notifications and tag updates. For more advanced functionalities, users can explore Stored Procedures.

Queries
Queries configuration properties in the Dataset module enable users to create and manage data retrieval queries efficiently. Key fields include:
Dataset Query Configuration Properties | |
|---|---|
Column | Description |
Name | Enter a name for the query. The system allows you to know if the name is not valid. |
DB | Select the database configuration. |
SqlStatement | Enter the query using SQL syntax. You can embed tags directly on the SQL statement, embracing the tag with curtly brackets. E.g. " Alternatively, you can also update the SQLStatement with the Script Module accessing the property Dataset.Query.QueryName.SqlStatement. When doing so, if you access that property from multiple tasks, be aware of potential concurrency issues, for advanced information on that refer to the page Advanced Dataset Guide |
Mapping | Click "..." to select the tags that you want to populate with data from specific columns returned by the query. |
MappingDateTime | Select the time reference (UTC or Local). |
Description | Enter a description for the table configuration. |
Showing DataGrids Tables on Displays
One of the key features of the Dataset module is the ability to display query results on screens and dashboards using visualization tools like DataGrids. Here are some steps for using DataGrids to display query results:
- Create a query in the Dataset module to retrieve the desired data.
- In the Displays Module, add a DataGrid control to the screen or dashboard.
- Configure the DataGrid to display the query results by selecting the data source and column mappings.
- Save and preview the screen or dashboard to display the query results on the DataGrid.
Using Query Results on Scripts and Tags
Users can use query results to trigger actions in custom scripts and tags. Here are some steps for using query results in scripts and tags:
- Create a query in the Dataset module to retrieve the desired data.
- In the Scripting Module, create a custom script that references the query results.
- Use the query results to trigger specific actions within the script, such as sending notifications or updating tags.
- Save and execute the script to perform the desired actions.
