Re: Stored procedures

As far as I know, you always work with a ResultSet.
If you know your stored procedures will always return an Integer and you don't
wanna deal with the executeQuery and stuff every time, you could create a
class with methods explicitly for accesing your stored procedures, for
example:

assuming you have a pg function returning an INT, called countPeople(), you
could do

public class MyStoredProcs {
private static int executeAnyProc(Connection conn, String procName) throws
SQLException{
Statement stmt=conn.createStatement();
ResultSet rs=stmt.executeQuery("SELECT * FROM "+procName+"()");
rs.next();
return rs.getInt(1);
}

public static int countPeople() throws SQLException{
return executeAnyProc("countPeople");
}
};

You could add methods to access every stored procedure in your database (even
returning other data types), and you would use it like this in your code:

...
int count=MyStoredProcs.countPeople();
// do something with the value
if (count>100) {
...

hope this is what you were looking for.
