Executing Parameterized SELECT Statements

The following sections show the schema, instance, and response for the following parameterized query:

SELECT Id, Fullname FROM [My Contacts] WHERE Updated = @Updated

Mapping the SELECT Schema to the Request and Response

SELECT schemas in solicit-response send ports have both a response section and an input parameters section.

SELECT Schema

Below is an example schema for a parameterized query executed from a solicit-response send port.
