Hi,
I noticed in JDBCCategoryDataset class on line 235 it reads
Comparable columnKey = metaData.getColumnName(column);
I propose that it would be instead
Comparable columnKey = metaData.getColumnLabel(column);
The column name retrieves the name of the column in the original table and thus ignores renaming of the column using SQL's AS construct.
So it leaves no opportunity for the user to modify the name of the category.
