PostgreSQL 15.2
select
current.id as currentId,
current.date as currentDate,
current.position as currentPosition,
current.relevant_url as currentRelevantUrl,
current.restrictions_probability as currentRestrictionsProbability,
current.url_changed as currentUrlChanged,
current.identifier_id as currentIdentifierId,
current.phrase_id as phraseId,
previous.id as previousId,
previous.date as previousDate,
previous.position as previousPosition,
previous.relevant_url as previousRelevantUrl,
previous.restrictions_probability as previousRestrictionsProbability,
previous.url_changed as previousUrlChanged,
previous.identifier_id as previousIdentifierId,
semantics_clusters.id as clusterId,
semantics_clusters.name as clusterName,
site_pages.id as pageId,
site_pages.url as pageUrl,
site_pages.site_id as siteId,
site_sites.url as siteUrl,
semantics_core_phrases.frequency as frequency
from (
select
id,
date,
position,
relevant_url,
restrictions_probability,
url_changed,
identifier_id,
phrase_id
from overoptimisation
where identifier_id = 1) current
left join (
select
id,
date,
position,
relevant_url,
restrictions_probability,
url_changed,
identifier_id,
phrase_id
from overoptimisation
where identifier_id = 1) previous
on current.phrase_id = previous.phrase_id
inner join semantics_core_phrases on current.phrase_id = semantics_core_phrases.id
inner join semantics_clusters on semantics_core_phrases.cluster_id = semantics_clusters.id
inner join site_pages on semantics_clusters.page_id = site_pages.id
inner join site_sites on site_pages.site_id = site_sites.id
This select works. But I have failed to add sorting.
How can I add order by for these fields?
siteId
pageId
clusterId
frequency

I don't see any problem to add order by clause.
Basically your SQL is valid, you can check it, for example, here
If you add order by clause in the end, then it is valid too:
select
current.id as currentId,
current.date as currentDate,
current.position as currentPosition,
current.relevant_url as currentRelevantUrl,
current.restrictions_probability as currentRestrictionsProbability,
current.url_changed as currentUrlChanged,
current.identifier_id as currentIdentifierId,
current.phrase_id as phraseId,
previous.id as previousId,
previous.date as previousDate,
previous.position as previousPosition,
previous.relevant_url as previousRelevantUrl,
previous.restrictions_probability as previousRestrictionsProbability,
previous.url_changed as previousUrlChanged,
previous.identifier_id as previousIdentifierId,
semantics_clusters.id as clusterId,
semantics_clusters.name as clusterName,
site_pages.id as pageId,
site_pages.url as pageUrl,
site_pages.site_id as siteId,
site_sites.url as siteUrl,
semantics_core_phrases.frequency as frequency
from
(
select
id,
date,
position,
relevant_url,
restrictions_probability,
url_changed,
identifier_id,
phrase_id
from
overoptimisation
where
identifier_id = 1
) current
left join (
select
id,
date,
position,
relevant_url,
restrictions_probability,
url_changed,
identifier_id,
phrase_id
from
overoptimisation
where
identifier_id = 1
) previous on current.phrase_id = previous.phrase_id
inner join semantics_core_phrases on current.phrase_id = semantics_core_phrases.id
inner join semantics_clusters on semantics_core_phrases.cluster_id = semantics_clusters.id
inner join site_pages on semantics_clusters.page_id = site_pages.id
inner join site_sites on site_pages.site_id = site_sites.id
order by
siteId
The same way you can order by pageId, clusterId, frequency
