If your staging control accesses the data from a database table, you have the capability of defining the selection criteria. XAI inbound services that reference the CISStagingUpload adapter may contain a collection of fields that are used in an SQL WHERE clause. When adding a new XAI Staging Control record, you can define the values for the WHERE clause.
For example, imagine that you have a work management system where new premises are defined. Rather than waiting for this system to "push" new data to you, you design the interface to have the system "pull" the new data by looking directly at the "new property" database table.
The Request XML for your XAI service contains SQL statements used to access the data. You could define a Staging Control Parameter of "Add Date". When creating your staging control, you may enter a parameter value of today's date. When this record is processed, it only retrieves new properties from this work management table whose Add Date is today.
The following example shows part of the Request XML schema for an XAI Service that SELECTs premises based on postal code.
The postal code value to substitute into the WHERE clause is defined on the individual XML Staging Control records.
