Jeff, Nice one.
However, it does not quite work with my DBD and database. What I see is the first 70 rows repeated as I scroll through the table. The SQL being executed does not seem correct: select * from ( select top 70 * from ( select top 70 col,col from table ) as foo ) as bar then when you go past the 70th row I get variations like: select * from ( select top 70 * from ( select top 350 col,col from table ) as foo ) as bar which obviously returns the same first 70 rows. I'm investigating. I think the issue may be in SQL-Abstract-Limit. Do you have any ideas? Martin -- Martin J.
