Java Database Connectivity (JDBC)

Hello,
I am writing a query and execute it with rs = statement.executeQuery(query)
everything works fine until rs tries to retrieve the second value.
rs.getString(1) works but fails while working on rs.getString(2).
I executed the query on sql and that works fine as well. My exact error log is:

java.sql.SQLException: Invalid Column Index
