Where are Named Queries Used?
Named Queries may be used in multiple locations in Ignition. They are used in all the same places that a normal SQL query would be used. Here are a few examples of locations in which named queries can be used. A more detailed example of a named query is provided here.
Binding
A Query Binding type has been added to leverage named queries for any component property bindings. Named Query Parameters may be bound to Tags or other properties on the same window, allowing your users to modify the resulting dataset by manipulating other components similar to the original SQL Query binding type. You can also select and update a query to simulate a bi-directional binding to the database.

Reporting
A Named Query Data Source has been added to Reports. Report Parameters may be used by the Named Query to generate dynamic reports.

Scripting
The system.db.runNamedQuery() function may be used to called a Named Query from any Python Script. This provides a secure method to execute a query from any location in Ignition.
