resultset type

good day,
i use connection.preparecall to call a procedure that returns some rows.
my java code has to do something with the last row returned. so, in order to perform that logic, i could comeup with only two options

1. we have to find out the total rows returned which can be done in the procedure. is there a way to find the total rows returned by the cursor, without doing looping and fetching.

2. use resultset.isLast(). i have used the following code.
callableStatement = connection.prepareCall("{call Pkg_test.prget(?,?,?)}", ResultSet.TYPE_SCROLL_SENSITIVE, ResultSet.CONCUR_UPDATABLE);
but somehow the type is reset to TYPE_FORWARD_ONLY by the driver. why is my type not feasible. due to this, i couldn't use isLast().

have a nice day,
krishna prasad


have a great day,

Why not use ORDER BY to change the order around so the last item now is the first item then, also combined with a limitation on the number of rows (TOP 1 in MS SQL Server, LIMIT 0 in MySQL).
