This portal is to open public enhancement requests against IBM Z Software products. To view all of your ideas submitted to IBM, create and manage groups of Ideas, or create an idea explicitly set to be either visible by all (public) or visible only to you and IBM (private), use the IBM Unified Ideas Portal (https://ideas.ibm.com).
We invite you to shape the future of IBM, including product roadmaps, by submitting ideas that matter to you the most. Here's how it works:
Start by searching and reviewing ideas and requests to enhance a product or service. Take a look at ideas others have posted, and add a comment, vote, or subscribe to updates on them if they matter to you. If you can't find what you are looking for,
Post an idea.
Get feedback from the IBM team and other customers to refine your idea.
Follow the idea through the IBM Ideas process.

We often generate services to retrieve SQL data from AS/400 using the Data Access Application wizard. The generated services contain several functions amongst which the function to retrieve a list of data which can be specified with the fromTablesWhere attribute. This function is called ?GetxxxxxxxxList'. In this function 2 SQL statements are prepared: 1 to retrieve the data, and 1 to retrieve the row count. This works OK. However when we set the fromTablesWhere to retrieve the data in a sequence specified by an ?ORDER BY' the row count prepared statement fails. This is due to the fact that the ?ORDER BY' is not accepted in a ?SELECT COUNT(*)' statement.
To work around this problem we now included a few lines of code in every data service we create. In the GetxxxxxxxList function before the prepare of the count statement we add these lines in order to remove the ?ORDER BY' part:
length int = characterlen(clip(listSpec.fromTablesWhere));
startpos int = strlib.indexof(listSpec.fromTablesWhere,"ORDER BY");
if (startpos != 0)
listSpec.fromTablesWhere = listSpec.fromTablesWhere[1:startpos-1];
end
We like a solution where no manual changes are needed after generating a service by the Data Access Application wizard. If you consider this RFE to be a defect we'll be glad to open a PMR.
