I am looking to get the number of rows in a table however I can't seem to find any methods through the ResultSet and ResultSetMetaData classes .

As far as I know the only way to get the number of records in a resultset is to read through the whole resultset and count (put the info in a collection so you can read through it again if need be) or make a seperate query (or as a returned field if you want)using the COUNT(*) database function.

hmm i think i found an even faster way of dooing this . Since i like keeping sequences tied up to my row numbers i simply do
select currval('sequence_of_hugetable') and get the last row's nr
