Whats the difference between BIRT sorting and a SQL ORDER BY clause?
BIRT provides a sorting option on tables and lists. When you define groups, BIRT implicitly defines a sort order. When using these options, BIRT will perform the sorting within BIRT’s own data engine. If your SELECT statement has an ORDER BY clause, and you omit the sort specification within BIRT, then you can ensure that the sorting is done on the database instead of in BIRT.
