I think your asking about multiple result sets, not multiple columns in a single result set.
In that case, you have to make sure the database/driver support this fluidly. If so, you can use getMoreResults() and getResultSet() to iterate through additional results sets.
I refer you to the following IBM article:
1. Invoke the Statement.execute method or PreparedStatement.execute method to call the stored procedure. Use PreparedStatement.execute if the stored procedure has input parameters. 2. Invoke the getResultSet method to obtain the first result set, which is in a ResultSet object. 3. In a loop, position the cursor using the next method, and retrieve data from each column of the current row of the ResultSet object using getXXX methods. 4. If there are n result sets, repeat the following steps n-1 times: 1. Invoke the getMoreResults method to close the current result set and point to the next result set. 2. Invoke the getResultSet method to obtain the next result set, which is in a ResultSet object. 3. In a loop, position the cursor using the next method, and retrieve data from each column of the current row of the ResultSet object using getXXX methods.
