Executing Multiple Select Queries in a Single attempt

Question

HI,
I executed two select queries in a single statement execute. It is executing without any error. Hence there must be two resultset objects within that single statement.
What the problem is that I m able to fetch the first resultset and its data, But I execute stmt.getMoreResults() to move to the next resultset, it returns false, which means there is no more results. I want to know what is the problem ?? (Record exist in the database for both queries)
And How can I rertieve both the resultsets. ??
Plz help me asap.
For ur convenience I m posting the Java code also which I m trying.
sql.delete(0, sql.length());
sql.append("select FIRST_NAME , MIDDLE_NAME , LAST_NAME from USER_MASTER where USER_ID=4;");
sql.append("select producttransaction_id, product_type from product_transaction where transaction_id=102 order by product_type desc");
Statement stmt = con.createStatement();
stmt.execute(sql.toString());
int resultsetcount =1;
ArrayList arrlist = new ArrayList();
rs = stmt.getResultSet();
if(rs !=null)
if(rs.next())
.........// logic here working properly
//Now when I move to next resultset using the below statement
//it returns false indicating that there r no more results.
// Why this is so ?????
boolean moreresultsets = stmt.getMoreResults();
System.out.println("MoreResultsets::"+moreresultsets);
if(moreresultsets)
rs = stmt.getResultSet();          
if(rs!=null)
while(rs.next())
//...Logic.......
     rs.close();
Thanks

I've never seen this used the way you are using it. In my experience the only way to do this would be to execute a single SQL statement that returns multiple result sets - you are trying to append two SQL statements.
You could define an in-line procedure wrapping your two select statements, or you could define a stored procedure to do the same thing. Then (either way) use CallableStatement to execute the call to the procedure.
