A web operation is a child object of a web service. It allows you to define the SQL statement of a web service and to display its parameters and result columns.
Web Operation Properties
You can modify an object's properties from its property sheet. To open a web operation property sheet, double-click its Browser entry in the Operations folder beneath the parent web service. The following sections detail the property sheet tabs that contain the properties most commonly entered for web operations.
Web Operation Result Columns
Result columns are sub-objects of web operations. They are part of the SQL statement defined in the Implementation tab of a web operation property sheet, and belong to a table in the target database. They are listed in the Result Columns tab of a web operation property sheet.
