E.2 Simplify access for single-row results
You can use the Fetch only single row for queries option for query operations that you
know will return only a single row to reduce the complexity of the service response data
structure. It simplifies the message response by removing the tag around the single
row result. Since it’s known that the query operation only returns one result row, the data
web services runtime can skip the row delimiter tag in the response.
TheRankEmployee operation for example always returns a single row only. To remove
the tag:
1. From the Data Project Explorer, right-click the operation in your web service and
select Edit, as shown in Figure E.7.

2. Select the Fetch only single row for queries option and click Finish as shown in
Figure E.8.
