Callable Statatement returning multiple Result Sets

Question

Hello all,
I've got a stored procedure that will be returning multiple result sets and i was wondering if someone could show me how to pull the multiple result sets out of the CallableStatement object. Any help would be greatly appreciated.

Here is a sample that does what you want. You will have to substitute the call to DBConn.getConnection() with your own DB connection. Also remove the import of com.ovotron.util.*.import com.ovotron.util.*;
import java.sql.*;
public class MultiSQL {
    private static Connection conn = null;
    public static void main(String[] args) {
        // Just gets a connection to the DB.
        conn = DBConn.getConnection();
        getResults(conn);
    * Cycles through multiple result sets returned from a stored procedure.
    * Only the first column is output.
    * <p>
    private static void getResults(Connection conn) {
        // Not sure which DBMS you are using. This is the syntax for
        // SQLServer V7.0.
        String            sql     = "{call getMultiResults}";
        CallableStatement stmt    = null;
        ResultSet         rs      = null;
        int               setNo   = 0;
        try {
            stmt = conn.prepareCall(sql);
            boolean found = stmt.execute();
            while (found) {
                setNo++;
                rs = stmt.getResultSet();
                while (rs.next()) {
                    System.out.println("Result set " + setNo +
                                       ": value: " + rs.getString(1));
                    System.out.flush();
                rs.close();
                found = stmt.getMoreResults();
        catch (SQLException e) {
            e.printStackTrace();
        finally {
            try {
                if (rs   != null) rs.close();
                if (stmt != null) stmt.close();
            catch (SQLException e) {
                // Tried already to clean up.
}The procedure I used is:CREATE PROCEDURE [getMultiResults] AS
select  col1 from tab1;
select col2 from tab1;
select col3 from tab1;Of course you will need to create and populate tab1.
