Getting Started with IBM Data Studio for DB2

376 Getting Started with IBM Data Studio for DB2
Only the maximum number of result sets returned is known, which forces Data Studio to
assign a very generic result set definition represented by the
anonymousResultSetType, as shown in Listing E.6.
Listing E.6 – The anonymousResultSetType
You can see the reference to the anonymousResultSetType in the XML schema definition
for the PRODUCT_CATALOG stored procedure response message, as shown in Listing E.5.
Listing E.5 – Reference to the anonymousResultSetType
The generic result set information can cause problems with web service clients that rely on
the message schema provided with the WSDL file – as you could see in Chapter 10 with
the Web Services Explorer, where the result set content was not displayed correctly
(Figure 10.25).
Data Studio provides a way to circumvent this problem, but your stored procedure must
match the criteria that it always returns the same number of result sets with the same
metadata information for every possible invocation. If this is the case, you can add a
more detailed result set XML schema. Follow these steps to add the additional result set
information for thePRODUCT_CATALOG procedure:
1. From the Data Project Explorer, right-click the PRODUCT_CATALOG operation
and select Edit to open the Edit Operation window.
2. Click Next to open the Generate XML Schema for Stored procedure page, then
click Generate, as shown in Figure E.9.
