Select and update in same instruction

Question

Can i select and update a column in table by one query only
I donot want to execute two queries one for updation and one for retrieval
e.g. instead of UPDATE t1 set val=val+1 and then SELECT val from t1;
i wanna have a single query (compliant to mysql and ORACLE)
because when i passa query UPDATE t1 set val=val+1; SELECT val from t1; on the command prompt is is fine but when i do so through jdbc it gives me errror
please help

Why would a stored procedure change anything?
The stored procedure would have the UPDATE ... ; SELECT sequence in it.
Which results in the same "work" the database has to do, compared to sending the two statements via JDBC.
The only thing that a stored procedure would save, is the second JDBC call, but I doubt that this makes a big difference (provided this is not done in a loop. Then I'd retrieve the new values in one statement after all the updates have been committed)
So I would simply do Statement statement = connection.createStatement();
int rows = statement.executeUpdate("UPDATE ....");
ResultSet rs = statement.executeQuery("SELECT ... ");
String val = null;
if (rs.next()) val = rs.getString(1);
rs.close();The code for the stored procedure would look very similar to this with the disadvantage that that you have to maintain it for every DBMS that has to be supported.
