Subject RE: How to get table info from DynaBeans in Iterator returned in query() or fetch()?

Thanks for the info, I figured that out when I was going through the
code. It is a pity as I am using PostgreSQL :(

Thanks again

Depending on the database you're working against, DdlUtils may not be
able to determine the table from the result set alone. E.g. PostgreSQL
does not provide enough info for this. This is why there are variants of
the fetch/query methods where you gan give table hints to DdlUtils. Only
if DdlUtils can resolve the table(s) and column(s) in the result, set, a
SqlDynaClass/SqlDynaBean is used, otherwise it is a plain DynaBean.
