Thanks a lot Christophe,
Is there any advantage and/or performance increase using QueryBuilder
instead of using dql directly? or this is just for developer convenience?
There is no real performance change (well, at level of
micro-optimisations, providing the string directly in the source code
will be faster than doing a building with concatenation, but this is
totally negligeable compared to the query execution).
the main advantage of the QueryBuilder is that you have an
object-oriented builder, allowing to reuse your building logic (you can
pass the builder to a method adding some filtering), while doing the
same with DQL strings would require doing weird string replacements (and
likely buggy).
