I have 3 tables :
table1 : "vw_dimserver" :[ServerKey,ServerNm,ServerCurrentAssignedToNm] for example : [1234,hasgapp0108,Aya]
table2 "vw_DimWorker" : [WorkerEmailNm, WorkerIdsid] . for example : [Aya, akhate] , [Genna,gshysh] , [mish,mishka] (it's like name and username)
table3 "vw_FactHardwareAssetContact" : [ServerKey,HardwareAssetWorkerKey, HardwareAssetContactTypeNm]. for example : [1234,Aya,support]
[1234,Genna,Customer]
[1234,Mish,patch] ( it's server key and the name of the contact and the contact type, if it's support or customer or patch)
I need the output to be in one row:
[ServerNm,WorkerIdsid of the ServerCurrentAssignedToNm, WorkerIdsid of the Customer, WorkerIdsid of the support]
[hasgapp0108,akhate,gshysh,mishka]
Now I need joins with the usernames table to get the username of each user.
I did it with Full outer join.
the code is :
SELECT
vw_dimserver.ServerNm as hostname ,
(vw_DimWorker1.WorkerIdsid) as username,
(vw_DimWorker2.WorkerIdsid) as [Primary Support Contact],
(vw_DimWorker3.WorkerIdsid) as [Primary Customer Contact]
from vw_dimserver
inner join vw_FactHardwareAssetContact on vw_dimserver.ServerKey = vw_FactHardwareAssetContact.HardwareAssetKey
inner join vw_DimWorker as vw_DimWorker1 on vw_DimWorker1.WorkerEmailNm = vw_dimserver.ServerCurrentAssignedToNm
full outer join vw_DimWorker as vw_DimWorker2 on CONVERT(varchar(11),vw_FactHardwareAssetContact.HardwareAssetWorkerKey ) = vw_DimWorker2.workerWWID and vw_FactHardwareAssetContact.HardwareAssetContactTypeNm = 'Support' and vw_FactHardwareAssetContact.HardwareAssetPrimaryInd = '1' and( vw_FactHardwareAssetContact.HardwareAssetWorkerKey is not NULL)
full outer join vw_DimWorker as vw_DimWorker3 on CONVERT(varchar(11),vw_FactHardwareAssetContact.HardwareAssetWorkerKey ) = vw_DimWorker3.workerWWID and vw_FactHardwareAssetContact.HardwareAssetContactTypeNm = 'Customer' and vw_FactHardwareAssetContact.HardwareAssetPrimaryInd = '1' and( vw_FactHardwareAssetContact.HardwareAssetWorkerKey is not NULL)
where vw_dimserver.ServerNm ='hasgapp0108' and (vw_DimWorker2.workerWWID is not null or vw_DimWorker3.workerWWID is not null ) and ( ServerCurrentSubStatusCd != 'duplicate_error' or ServerCurrentSubStatusCd is NULL )
The output is two rows:
[hostname username Support Customer ]
[hasgapp0108 akhate NULL gshysh],
[hasgapp0108 akhate akhate NULL]
and I need it to be one row :
[hostname username Support Customer]
[hasgapp0108 akhate akhate gshysh]
My manager didn't accept the solutaion :
select max(username1),max(username2)...
I need to do it with joins.
Try this with inner join and group_concat:
SELECT vw_dimserver.ServerNm as hostname , group_concat(vw_DimWorker1.WorkerIdsid) as username, group_concat(vw_DimWorker2.WorkerIdsid) as [Primary Support Contact], group_concat(vw_DimWorker3.WorkerIdsid) as [Primary Customer Contact]
from vw_dimserver
inner join vw_FactHardwareAssetContact on vw_dimserver.ServerKey = vw_FactHardwareAssetContact.HardwareAssetKey
inner join vw_DimWorker as vw_DimWorker1 on vw_DimWorker1.WorkerEmailNm = vw_dimserver.ServerCurrentAssignedToNm
full outer join vw_DimWorker as vw_DimWorker2 on CONVERT(varchar(11),vw_FactHardwareAssetContact.HardwareAssetWorkerKey ) = vw_DimWorker2.workerWWID and vw_FactHardwareAssetContact.HardwareAssetContactTypeNm = 'Support' and vw_FactHardwareAssetContact.HardwareAssetPrimaryInd = '1' and( vw_FactHardwareAssetContact.HardwareAssetWorkerKey is not NULL)
full outer join vw_DimWorker as vw_DimWorker3 on CONVERT(varchar(11),vw_FactHardwareAssetContact.HardwareAssetWorkerKey ) = vw_DimWorker3.workerWWID and vw_FactHardwareAssetContact.HardwareAssetContactTypeNm = 'Customer' and vw_FactHardwareAssetContact.HardwareAssetPrimaryInd = '1' and( vw_FactHardwareAssetContact.HardwareAssetWorkerKey is not NULL)
where vw_dimserver.ServerNm ='hasgapp0108' and (vw_DimWorker2.workerWWID is not null or vw_DimWorker3.worker
group by vw_dimserver.ServerNm
You could use an inner join if you need only matching result
SELECT
s.ServerKey,
s.ServerNm,
group_concat(w.WorkerIdsid)
FROM vw_dimserver s
INNER JOIN vw_FactHardwareAssetContact c
ON s.ServerKey = c.ServerKey
INNER JOIN vw_DimWorker w
ON c.HardwareAssetWorkerKey = w.WorkerEmailNm
GROUP BY s.ServerKey,
s.ServerNm
OR You could use left join if there are not all matching
SELECT
s.ServerKey,
s.ServerNm,
group_concat(w.WorkerIdsid)
FROM vw_dimserver s
LEFT JOIN vw_FactHardwareAssetContact c
ON s.ServerKey = c.ServerKey
LEFT JOIN vw_DimWorker w
ON c.HardwareAssetWorkerKey = w.WorkerEmailNm
GROUP BY s.ServerKey,
s.ServerNm
SELECT vw_dimserver.ServerNm as hostname , (vw_DimWorker1.WorkerIdsid) as username, (vw_DimWorker2.WorkerIdsid) as [Primary Support Contact], (vw_DimWorker3.WorkerIdsid) as [Primary Customer Contact]
from vw_dimserver
full outer join vw_FactHardwareAssetContact as vw_FactHardwareAssetContact1
on (vw_dimserver.ServerKey = vw_FactHardwareAssetContact1.HardwareAssetKey and vw_FactHardwareAssetContact1.HardwareAssetContactTypeNm = 'Support' and vw_FactHardwareAssetContact1.HardwareAssetPrimaryInd = '1' )
full outer join vw_DimWorker as vw_DimWorker1 on CONVERT(varchar(11),vw_FactHardwareAssetContact1.HardwareAssetWorkerKey ) = vw_DimWorker1.workerWWID
full outer join vw_DimWorker as assings on assings.WorkerEmailNm = vw_dimserver.ServerCurrentAssignedToNm
full outer join vw_FactHardwareAssetContact as vw_FactHardwareAssetContact2 on (vw_dimserver.ServerKey = vw_FactHardwareAssetContact2.HardwareAssetKey and vw_FactHardwareAssetContact2.HardwareAssetContactTypeNm = 'Customer' and vw_FactHardwareAssetContact2.HardwareAssetPrimaryInd = '1' )
full outer join vw_DimWorker as vw_DimWorker2 on CONVERT(varchar(11),vw_FactHardwareAssetContact2.HardwareAssetWorkerKey ) = vw_DimWorker2.workerWWID
full OUTER join vw_FactHardwareAssetContact as vw_FactHardwareAssetContact11 on (vw_dimserver.ServerKey = vw_FactHardwareAssetContact11.HardwareAssetKey and vw_FactHardwareAssetContact11.HardwareAssetContactTypeNm = 'Support' and vw_FactHardwareAssetContact11.HardwareAssetPrimaryInd = '0' )
full outer join vw_DimWorker as vw_DimWorker11 on CONVERT(varchar(11),vw_FactHardwareAssetContact11.HardwareAssetWorkerKey ) = vw_DimWorker11.workerWWID

Someone please explain the difference between parent query and sub query? How do I understand?
e.g:

I'm currently stuck here and don't know what to do next since I can't use the tv_main alias into the 2 level deep subquery. Here's my code (I commented the part that have a problem). Any help will be appreciated. Thanks.

tv_main.vesselName,

GROUP BY tc_stat.personnel_id

I finally solve it. I didn't know that mysql only allow correlation of 1 deep level.

I have a principal requet with 2 requets in. I have a problem in my second nested query, I have a condition on id and if I made my request id = 10 takes a long time to execute, so if I replace it by id LIKE 10 my request execute in one second.
Here the request:
SELECT SQL_NO_CACHE contact_groupe.id_contact_groupe
FROM toto.contact_groupe
LEFT JOIN toto.`contact` AS `contact`
ON ((toto.contact_groupe.id_contact_groupe = toto.contact.id_contact_groupe))

the line is the following problem toto.project.id_project = '10' and I don't understand why the time to execute request is so different between = and LIKE
Let's start with your subquery. Those 17 lines that you've written are functionally identical to this, so why not use this instead?
SELECT DISTINCT g.id_contact_groupe
FROM contact_groupe g
JOIN project p
ON p.id_contact_groupe = g.id_contact_groupe
WHERE g.en_attente = 0
AND p.id_project = 10
AND g.id_entreprise = 2
It shouldn't join on tbi2 if tbi1 finds a result, but it retrieving results from both tables.
The idea of this is to join on the item table but if there isn't an exact match, fallback to joining on '*'
(This is the same SQL statement as a previous question, but a different attempt... again.)

The problem is with the second SELECT (the column - HandlingStatus).
I don't understand but when the column has results (tested as a stand alone query) - I get an empty result set, and when there are no results - I get a result.
Why?
