Release 10.1A: OpenEdge Development:
.NET Open Clients

Passing a TABLE or TABLE-HANDLE as an OUTPUT parameter

When the client application calls a method with a static temp-table (TABLE parameter) OUTPUT parameter, the client must provide a variable of the strongly typed DataTable class provided by ProxyGen. In this case, the client does not need to instantiate the object.

When the client application calls a method with a dynamic temp-table (TABLE-HANDLE parameter) OUTPUT parameter, the client must provide a variable of type System.Data.DataTable. Again, the client does not need to instantiate the object. In this case, the parameter can be returned as Unknown or undefined. As a result, you must ensure the client code is written to handle these cases.

On return from the method, the client can access rows of the temp-table using the Rows property on the strongly typed DataTable or System.Data.DataTable class.

Any data in the parameter at the time of the method is replaced on return from the proxy call. All output data is immediately available to the client after the proxy call returns.
