ORDER BY makes data service fail

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.

    Thanks you for the input. We agree this is useful functionality, but we don't have a closed plan to deliver currently. We will consider this in our future planning.
