Hi Brian.
Minor update. As Sybase doesn't support LIMIT/OFFSET like structure (same
thing as for MSSQL) we use a method called "pivoting" (one column is used
as a "pivot" for retrieving other column values) for deriving row content
from tables. Now, problem is that pivoting requires "derived" tables.
Sorry, but this moment it has to stay as it is for proper dumping of Sybase
tables in general.
Kind regards,
Miroslav Stampar
