Unable to get complete data using mysql 3 joins query - mysql

Question

i have 1500 records in domains table but by using this query only get 1215 records. How to modify this query to give desired outcome and better performance
SELECT
d.id, d.domain_name, d.action, d.comment, d.agent_email,
d.assigned_date, d.added_date, dd.registered_on, dd.expiry_date,
dd.updated_date, dd.acquire_price, dd.acquire_date, dd.email,
dd.effective_price, dd.registrar, dd.status, dd.servers,
count(l.lead_domain), d.domainer_email, d.current_status,
d.undeveloped, d.sedo, d.afternic, d.flippa, d.uniregistry,
d.go_daddy, d.domr, d.minimum_offer, d.buy_it_now_price,
d.way_to_find_leads, dd.tlds_taken
FROM domains d
right join domains_data dd on d.domain_name=dd.domain_name
left outer join lead_domains l on d.domain_name=l.domain_name
and d.domainer_email=l.domainer_email
group by d.domain_name
having d.action='all' and d.domainer_email='abc#gmail.com'
order by d.added_date desc;

Answer 1

Your results depend on the domains_data table.
Since you are right joining domains to domains_data, the entries that are in domains_data are taken. If you want the entries of domains to be considered, use a left join like below.
SELECT d.id, d.domain_name, d.action, d.comment, d.agent_email, d.assigned_date, d.added_date, dd.registered_on, dd.expiry_date, dd.updated_date, dd.acquire_price, dd.acquire_date, dd.email, dd.effective_price, dd.registrar, dd.status, dd.servers, COUNT(l.lead_domain), d.domainer_email, d.current_status, d.undeveloped, d.sedo, d.afternic, d.flippa, d.uniregistry, d.go_daddy, d.domr, d.minimum_offer, d.buy_it_now_price, d.way_to_find_leads, dd.tlds_taken
FROM domains d
LEFT JOIN domains_data dd ON d.domain_name=dd.domain_name
LEFT OUTER JOIN lead_domains l ON d.domain_name=l.domain_name AND d.domainer_email=l.domainer_email
GROUP BY d.domain_name
HAVING d.action='all' AND d.domainer_email='abc#gmail.com'
ORDER BY d.added_date DESC;
If you are still not able to get the desired results, check the having conditions.

#Harshal As per my understanding, I don't think that query you have provided will work as GROUP BY rules are not followed properly.
SELECT d.id,
d.domain_name,
d.action,
d.comment,
d.agent_email,
d.assigned_date,
d.added_date,
dd.registered_on,
dd.expiry_date,
dd.updated_date,
dd.acquire_price,
dd.acquire_date,
dd.email,
dd.effective_price,
dd.registrar,
dd.status,
dd.servers,
(SELECT COUNT(lead_domain) FROM lead_domains WHERE domain_name = d.domain_name AND domainer_email = d.domainer_email) AS lead_domain,
d.domainer_email,
d.current_status,
d.undeveloped,
d.sedo,
d.afternic,
d.flippa,
d.uniregistry,
d.go_daddy,
d.domr,
d.minimum_offer,
d.buy_it_now_price,
d.way_to_find_leads,
dd.tlds_taken
FROM domains d
LEFT JOIN domains_data dd
ON d.domain_name = dd.domain_name
WHERE d.action = 'all'
AND d.domainer_email = 'abc#gmail.com'
ORDER BY
d.added_date DESC;
And as you have not provided any expected results, I am just guessing that my solution will work.

Here's my suggestion, filter first before joining other tables.
SELECT d.id
,d.domain_name
,d.action
,d.comment
,d.agent_email
,d.assigned_date
,d.added_date
,dd.registered_on
,dd.expiry_date
,dd.updated_date
,dd.acquire_price
,dd.acquire_date
,dd.email
,dd.effective_price
,dd.registrar
,dd.status
,dd.servers
,t1.cnt
,d.domainer_email
,d.current_status
,d.undeveloped
,d.sedo
,d.afternic
,d.flippa
,d.uniregistry
,d.go_daddy
,d.domr
,d.minimum_offer
,d.buy_it_now_price
,d.way_to_find_leads
,dd.tlds_taken
FROM domains d
inner join
(select domain_name, count(1) as cnt
from domain
where
action='all' and domainer_email='abc#gmail.com'
group by domain_name
) as t1 on t1.domain_name = d.domain_name
right join domains_data dd on d.domain_name=dd.domain_name
left outer join lead_domains l on d.domain_name=l.domain_name and d.domainer_email=l.domainer_email
order by d.added_date desc;
