How Do I Use Datasets?
Datasets have been re-written from scratch to be more powerful and easier to use. Unlike our previous Datasets (which required being saved in a POD file to utilize in the Windward engines), new Datasets can be used like all other Datasources. This makes Datasets easier to manage and deploy in an application.
Datasets are analogous to SQL views. They can help simplify Tag queries by showing only the relevant subset of a data source in the Data Tree views and Select Wizards.
Datasets are created in the Connection Editor for valid Datasource Providers. Valid Datasource Providers include
- SQL Datasources (Microsoft SQL Server, Oracle, MySQL, or DB2)
- XPath 2.0
- Microsoft Access (ODBC)
Datasets can be created by selecting the desired active Datasource connection and clicking the “Data Set” button. This creates an empty Dataset based on the selected Datasource.
Next, create a query for the Dataset by either manually entering a query or by using a Wizard. When you’re finished editing a Dataset, click “Update” to save all changes.
