Maybe this is a little tricky, but I think it might help you.

JDBC ResultSet objects have a getMetaData() method that returns a ResultSetMetaData object that contains, among other things, the column names and column types. You could do something like this:

ResultSet rs;
String strSQL;

...

strSQL = "create table tbl ("
for(i=0;i0)
        strSQL += ", "
    strSQL += rs.getMetaData().getColumnName(i) 
           + " " 
           + rs.getMetaData().getColumnType(i);
}
strSQL+= ")"

....

You can construct this way a valid SQL DML that has the columns you need. After that, all that remains is populate the table.

Hope this helps you.
