Not if you use an efficient object-relational tool.

You may want to take a look at Metastorage. This is a tool that
generates efficient persistent object classes from a model definition in
a simple XML format of classes, variables, relationships, validation
rules, functions to manipulate the objects.

Then Metastorage generates classes of persistent objects that perform
the necessary object-relational mapping that you can use right away in
your applications.

It supports its own Object Query Language (OQL) so you can express
object search and filter conditions, that may include parameter values
passed to your persistent object classes at runtime.

Metastorage compiles the OQL expressions into efficient SQL that is
embedded into the generate PHP code of the persistent object classes.

You may find all about Metastorage here:
