I have a tricky query. I need to select all recent versions of 2 types of members of administrator groups. Here is the query:
SELECT refGroup.*
FROM tblSystemAdministratorGroups refGroup
JOIN tblGroup refMem ON refGroup.AttributeValue = refMem.ObjectUID
This query will return all the administrator groups. The next step will be getting the members of these groups. Since I have 2 types of memberships (Explicit, Computed), I will have to use a LEFT JOIN to make sure that I am not excluding any rows.
SELECT refGroup.*
FROM tblSystemAdministratorGroups refGroup
-- The JOIN bellow can be excluded but it is here just to clarify the architecture
JOIN tblGroup refMem ON refGroup.AttributeValue = refMem.ObjectUID
LEFT JOIN tblGroup_ComputedMember cm ON refMem.ObjectUID = cm.GroupObjectID
LEFT JOIN tblGroup_ExplicitMember em ON refMem.ObjectUID = em.GroupObjectID
The last piece in the puzzle is to get the latest version of each member. For that I will have to use JOIN to exclude older versions:
JOIN (
SELECT MAX([ID]) MaxId
FROM [OmadaReporting].[dbo].tblGroup_ComputedMember
GROUP BY ObjectID
) MostRecentCM ON MostRecentCM.MaxId = cm.Id
and
JOIN (
SELECT MAX([ID]) MaxId
FROM [OmadaReporting].[dbo].tblGroup_ExplicitMember
GROUP BY ObjectID
) MostRecentEM ON MostRecentEM.MaxId = em.Id
The full query will be:
SELECT refGroup.*
FROM tblSystemAdministratorGroups refGroup
JOIN tblGroup refMem ON refGroup.AttributeValue = refMem.ObjectUID
LEFT JOIN tblGroup_ComputedMember cm ON refMem.ObjectUID = cm.GroupObjectID
JOIN (
SELECT MAX([ID]) MaxId
FROM [OmadaReporting].[dbo].tblGroup_ComputedMember
GROUP BY ObjectID
) MostRecentCM ON MostRecentCM.MaxId = cm.Id
LEFT JOIN tblGroup_ExplicitMember em ON refMem.ObjectUID = em.GroupObjectID
JOIN (
SELECT MAX([ID]) MaxId
FROM [OmadaReporting].[dbo].tblGroup_ExplicitMember
GROUP BY ObjectID
) MostRecentEM ON MostRecentEM.MaxId = em.Id
The issue is clear: The 2 JOIN to exclude old versions are also applied to the select statement and clearly no rows are returned. What would be the best solution to escape such situation and to return the intended values?
SELECT refGroup.*
FROM tblSystemAdministratorGroups refGroup
JOIN tblGroup refMem ON refGroup.AttributeValue = refMem.ObjectUID
LEFT JOIN (
select GroupObjectID, ID, max(ID) over (partition by ObjectID) as maxID
from tblGroup_ComputedMember
) cm ON refMem.ObjectUID = cm.GroupObjectID and cm.ID = cm.maxID
LEFT JOIN (
select GroupObjectID, ID, max(ID) over (partition by ObjectID) as maxID
from tblGroup_ExplicitMember
) em ON refMem.ObjectUID = em.GroupObjectID and em.ID = em.maxID
where cm.ID = cm.MaxID
What about using LEFT join in your last two joins?
LEFT JOIN (
SELECT MAX([ID]) MaxId
FROM [OmadaReporting].[dbo].tblGroup_ComputedMember
GROUP BY ObjectID
) MostRecentCM ON MostRecentCM.MaxId = cm.Id
And then in Where clause filter values as:
WHERE MostRecentCM.MaxId IS NOT NULL
OR
MostRecentEM.MaxId IS NOT NULL

I am trying to create one single query that will give me a distinct count for both the ActivityID and the CommentID. My query in MS Access looks like this:
SELECT
tbl_Category.Category, Count(tbl_Activity.ActivityID) AS CountOfActivityID,
Count(tbl_Comments.CommentID) AS CountOfCommentID
FROM tbl_Category LEFT JOIN
(tbl_Activity LEFT JOIN tbl_Comments ON
tbl_Activity.ActivityID = tbl_Comments.ActivityID) ON
tbl_Category.CategoryID = tbl_Activity.CategoryID
WHERE
(((tbl_Activity.UnitID)=5) AND ((tbl_Comments.PeriodID)=1))
GROUP BY
tbl_Category.Category;
I know the answer must somehow include SELECT DISTINCT but am not able to get it to work. Do I need to create multiple subqueries?
This is really painful in MS Access. I think the following does what you want to do:
SELECT ac.Category, ac.num_activities, aco.num_comments
FROM (SELECT ca.category, COUNT(*) as num_activities
FROM (SELECT DISTINCT c.Category, a.ActivityID
FROM (tbl_Category as c INNER JOIN
tbl_Activity as a
ON c.CategoryID = a.CategoryID
) INNER JOIN
tbl_Comments as co
ON a.ActivityID = co.ActivityID
WHERE a.UnitID = 5 AND co.PeriodID = 1
) as caa
GROUP BY ca.category
) as ca LEFT JOIN
(SELECT c.Category, COUNT(*) as num_comments
FROM (SELECT DISTINCT c.Category, co.CommentId
FROM (tbl_Category as c INNER JOIN
tbl_Activity as a
ON c.CategoryID = a.CategoryID
) INNER JOIN
tbl_Comments as co
ON a.ActivityID = co.ActivityID
WHERE a.UnitID = 5 AND co.PeriodID = 1
) as aco
GROUP BY c.Category
) as aco
ON aco.CommentId = ac.CommentId
Note that your LEFT JOINs are superfluous because the WHERE clause turns them into INNER JOINs. This adjusts the logic for that purpose. The filtering is also very tricky, because it uses both tables, requiring that both subqueries have both JOINs.
You can use DISTINCT:
SELECT
tbl_Category.Category, Count(DISTINCT tbl_Activity.ActivityID) AS CountOfActivityID,
Count(DISTINCT tbl_Comments.CommentID) AS CountOfCommentID
FROM tbl_Category LEFT JOIN
(tbl_Activity LEFT JOIN tbl_Comments ON
tbl_Activity.ActivityID = tbl_Comments.ActivityID) ON
tbl_Category.CategoryID = tbl_Activity.CategoryID
WHERE
(((tbl_Activity.UnitID)=5) AND ((tbl_Comments.PeriodID)=1))
GROUP BY
tbl_Category.Category;
I have two query to combine two results into one. However; my challenge is to get the second query look into the first query if it doesn't exist in the first query.
I changed my post to the actual query
SELECT Name.CO_ID, Name.FULL_NAME, Name.ID, rpt.date AS StartDate,
vw_Coords.TARGET_ID AS CoordID, vw_RegDirs.TARGET_ID AS
RDID
FROM Name INNER JOIN
Tops_Profile ON dbo.Name.ID = Tops_Profile.ID left
outer JOIN
vw_mz_rpt_leader_log rpt ON Name.CO_ID = rpt.ID LEFT
OUTER JOIN
vw_RegDirs ON Name.CO_ID = vw_RegDirs.CHAPTER LEFT
OUTER JOIN
vw_Coords ON Name.CO_ID = vw_Coords.CHAPTER LEFT OUTER
JOIN
Tops_Chapter ON Tops_Chapter.ID = Name.CO_ID
WHERE (Name.MEMBER_TYPE = 'm') AND (Tops_Profile.LDR = '1') and
LOG_TEXT like '%LEADER Change%'
union
SELECT Name.CO_ID, Name.FULL_NAME, Name.ID,
YEAR(dbo.Tops_Chapter.PST_DATE_LEAD) AS StartDate,
vw_Coords.TARGET_ID AS CoordID, vw_RegDirs.TARGET_ID AS
RDID
FROM Name INNER JOIN
Tops_Profile ON Name.ID = Tops_Profile.ID left outer
JOIN
vw_mz_rpt_leader_log rpt ON Name.CO_ID = rpt.ID LEFT
OUTER JOIN
vw_RegDirs ON Name.CO_ID = vw_RegDirs.CHAPTER LEFT
OUTER JOIN
vw_Coords ON Name.CO_ID = vw_Coords.CHAPTER LEFT OUTER
JOIN
Tops_Chapter ON Tops_Chapter.ID = Name.CO_ID
WHERE (Name.MEMBER_TYPE = 'm') AND (Tops_Profile.LDR = '1')
the scope is if the record exists in the first query don't bring it from second query.
Here's a quick and dirty way...
select *
from
(select id, Name, log.Date
from Name
inner join Log on Name.id = log.id
where log.text_log like '%Leader%'
union
select id, Name, Profile.Date
from Name
inner join profile on Name.id = profile.id
where profile.Leader = '1') d
order by row_number() over(partition by x.id order by x.Date asc)
Note, this doesn't care where John came from, it's simply finding the first occurrence based on the date which seems to be what you want.
You have altered your request. Suddenly both queries select from the same tables and a UNION (or UNION ALL for that matter) doesn't seem a good solution anymore.
There are very few differences between the two queries even. And looking at the whole it boils down to: select records for member_type = 'm' and tp.ldr = 1 and then keep only one record per name, preferredly one with log_text like '%LEADER Change%'. This is mere ranking, as already shown in my other answer. You only need one query to select all records in question and use TOP (1) WITH TIES to keep the best matches per name.
select top(1) with ties
n.co_id,
n.full_name,
n.id,
case when log_text like '%LEADER Change%' then rpt.date else year(tc.pst_date_lead) end
as startdate,
c.target_id as coordid,
rd.target_id as rdid
from name n
inner join tops_profile tp on n.id = tp.id
left outer join vw_mz_rpt_leader_log rpt on n.co_id = rpt.id
left outer join vw_regdirs rd on n.co_id = rd.chapter
left outer join vw_coords c on n.co_id = c.chapter
left outer join tops_chapter tc on tc.id = n.co_id
where n.member_type = 'm'
and tp.ldr = 1
order by row_number() over (
partition by n.id
order by case when log_text like '%LEADER Change%' then 1 else 2 end);
As you said you just want only one record per name, I am using ROW_NUMBER. If you want more, use RANK instead.
It's not clear why you are joining the tops_chapter table. Is log_text a column in that table? (You should use a table qualifier for this column in your query.) If it isn't, then the join is superfluous and you can remove it from your query.
Use row_number and select id's with least date
with cte as
(select id, Name, log.Date
from Name
inner join Log on Name.id = log.id
where log.text_log like '%Leader%'
union all
select id, Name, Profile.Date as log.date
from Name
inner join profile on Name.id = profile.id
where profile.Leader = '1'
) , ct1 as (select id,name,log.date, ROW_NUMBER() over (partition by id order by log.date) rn from cte )
select id,name,log.date from ct1 where rn = 1
where profile.Leader = '1'
and id not in ( select Name.id
from Name
inner join Log
on Name.id = log.id
where log.text_log like '%Leader%' )
You can use NOT EXISTS in the second query to filter out already existing Name records:
select id, Name, log.Date
from Name
inner join Log on Name.id = log.id
where log.text_log like '%Leader%'
union
select n1.id, n1.Name, Profile.Date
from Name as n1
inner join profile on n1.id = profile.id
where profile.Leader = '1' and
not exists (select 1
from Name as n2
inner join Log on n2.id = Log.id
where Log.text_log like '%Leader%' and
n2.id = n1.id and n2.name = n1.name)
The query below finds logdate and profiledate for each name. If there is a logdate, the logdate will be diplayed else the profile date will be displayed. If both don't exist the Name won't be displayed.
select id, Name, coalesce(log.Date,profile.date)
from Name
left join Log on Name.id = log.id and log.text_log like '%Leader%'
left join profile on Name.id = profile.id and profile.Leader = '1'
where coalesce(log.Date,profile.date) is not null
You can add a rank to your two queries. Then per ID you keep the record(s) with the better rank (using ORDER BY with TOP (1) WITH TIES).
select top(1) with ties
id, name, date
from
(
select n.id, n.name, log.date, 1 as rnk
from name n
inner join log on name.id = log.id
where log.text_log like '%Leader%'
union all
select n.id, n.name, profile.date, 2 as rnk
from name n
inner join profile on name.id = profile.id
where profile.leader = '1'
) data
order by rank() over (partition by id order by rnk);
I have my initial statement which is :
SELECT TEAM.ID PKEY_SRC_OBJECT,
TEAM.MODF_DAT UPDATE_DATE,
TEAM.MODF_USR UPDATED_BY,
PERSO.FIRST_NAM FISRT_NAME
FROM TEAM
LEFT OUTER JOIN PERSO ON (TEAM.ID=PERSO.TEAM_ID)
I want to calculate some "flags" and return them in my initial statement.
There are 3 flags which can be calculated like this :
1) Flag ISMASTER:
SELECT Count(*)
FROM TEAM_TEAM_REL A, TEAM B
WHERE B.PARTY_PTY_ID = A.RLTD_TEAM_ID
AND CODE = 'Double';
2) Flag ISAGENT:
SELECT Count(*)
FROM TEAM_ROL_REL A, TEAM B
WHERE B.PARTY_PTY_ID = A.TEAM_ID;
3) Flag NUMPACTS:
SELECT Count(*)
FROM TEAM_ROL_REL A,
TEAM_ROL_POL_REL B,
PERSO_POL_STA_REL C,
TEAM D
WHERE A.ROL_CD IN ('1','2')
AND A.T_ROL_REL_ID = B.P_ROL_REL_ID
AND B.P_POL_ID = C.P_POL_ID
AND C.STA_CD = 'A'
AND D.PARTY_PTY_ID = A.TEAM_ID;
To try to achieve this, I've updated my initial statement like this :
WITH ABC AS (
SELECT TEAM.ID PKEY_SRC_OBJECT,
TEAM.MODF_DAT UPDATE_DATE,
TEAM.MODF_USR UPDATED_BY,
PERSO.FIRST_NAM FISRT_NAME
FROM TEAM
LEFT OUTER JOIN PERSO ON (TEAM.ID=PERSO.TEAM_ID)
)
SELECT ABC.*, MAST.ISMASTER, AGENT.ISAGENT, PACTS.NUMPACTS FROM ABC
LEFT OUTER JOIN (
select
RLTD_TEAM_ID,
Count(RLTD_TEAM_ID) OVER (PARTITION BY RLTD_TEAM_ID) as ISMASTER
FROM TEAM_TEAM_REL
WHERE CODE = 'Double'
) MAST
ON ABC.PKEY_SRC_OBJECT = MAST.RLTD_TEAM_ID
LEFT OUTER JOIN (
select
TEAM_ID,
Count(TEAM_ID) OVER (PARTITION BY TEAM_ID) as ISAGENT
FROM TEAM_ROL_REL
) AGENT
ON ABC.PKEY_SRC_OBJECT = AGENT.TEAM_ID
LEFT OUTER JOIN (
select
TEAM_ID,
Count(TEAM_ID) OVER (PARTITION BY TEAM_ID) as NUMPACTS
FROM TEAM_ROL_REL, TEAM_ROL_POL_REL, PERSO_POL_STA_REL
WHERE TEAM_ROL_REL.ROL_CD IN ('1','2')
AND TEAM_ROL_REL.T_ROL_REL_ID = TEAM_ROL_POL_REL.P_ROL_REL_ID
AND TEAM_ROL_POL_REL.P_POL_ID = PERSO_POL_STA_REL.P_POL_ID
AND PERSO_POL_STA_REL.STA_CD = 'A'
) PACTS
ON ABC.PKEY_SRC_OBJECT = PACTS.TEAM_ID;
For the two first flags (ISMASTER and ISAGENT) I get the result in less than 1min, but for the last flag (NUMPACTS) it runs few minutes without provide any result.
I think my statement is too heavy, maybe I should do it in a totally different way.
I think you have perhaps over complicated things.
You could do this (assuming I have understood your requirements correctly) like so:
WITH ttr AS (SELECT rltd_team_id,
COUNT(*) is_master
FROM team_team_rel
AND CODE = 'Double'
GROUP BY rltd_team_id),
trr AS (SELECT team_id,
COUNT(*) is_agent
FROM team_rol_rel
GROUP BY team_id)
pacts AS (SELECT trr1.team_id,
COUNT(*) num_pacts
FROM team_rol_rel trr1
INNER JOIN team_rol_pol_rel trpr ON (trr1.t_rol_rel_id = trpr.p_rol_rel_id)
INNER JOIN perso_pol_sta_rel ppsr ON (trpr.p_pol_id = ppsr.p_pol_id
WHERE trr1.rol_cd IN ('1', '2')
AND ppsr.st_cd = 'A'
GROUP BY trr1.team_id)
SELECT t.id pkey_src_object,
t.modf_dat update_date,
t.modf_usr updated_by,
p.first_nam first_name,
ttr.is_master,
trr.is_agent,
pacts.num_pacts
FROM team t
LEFT OUTER JOIN perso p ON t.id = p.team_id
LEFT OUTER JOIN ttr ON t.party_pty_id = ttr.rltd_team_id
LEFT OUTER JOIN trr ON t.party_pty_id = trr.team_id
LEFT OUTER JOIN pacts ON t.pkey_src_object = pacts.team_id;
N.B. untested, since you didn't provide any test data.
The Query below produces a record for each Entry in the SP_ScheduleEvent Table.
SELECT m.MaterialId, m.MaterialTitle, se.EventDateTime, c.ChannelName
FROM GB_Material m
LEFT OUTER JOIN SP_ScheduleEvent se on se.MaterialName = m.MaterialName
INNER JOIN SP_Schedule s on s.ScheduleID = se.ScheduleID
INNER JOIN GB_Channel c on c.ChannelID = s.ChannelID
WHERE LOWER(m.MaterialName) like '%foo%' OR LOWER(m.MaterialTitle) like '%foo%'
I want to limit the result set by the nearest future EventDateTime.
So per material name i would like to see one EventDateTime, which should be the nearest future date to the current time.
And lastly, a record may not exist in the SP_ScheduleEvent table for a particular materialname, in which case there should be null returned for the EventDateTime column
SQLFiddle
How would i go about doing this?
First, your LEFT JOIN is immaterial, because the subsequent joins make it an INNER JOIN. Either use LEFT JOIN throughout the FROM statement or switch to INNER JOIN.
I think you can use ROW_NUMBER():
SELECT t.*
FROM (SELECT m.MaterialId, m.MaterialName, m.MaterialTitle, se.EventDateTime,
ROW_NUMBER() over (PARTITION BY m.MaterialId OVER se.EventDateTime DESC) as seqnum
FROM GB_Material m INNER JOIN
SP_ScheduleEvent se
on se.MaterialName = m.MaterialName INNER JOIN
SP_Schedule s
on s.ScheduleID = se.ScheduleID INNER JOIN
GB_Channel c
on c.ChannelID = s.ChannelID
WHERE se.EventDateTime > getdate() AND
(LOWER(m.MaterialName) like '%foo%' OR LOWER(m.MaterialTitle) like '%foo%')
) t
WHERE seqnum = 1
ORDER BY se.EventDateTime;
Use the ROW_NUMBER() function:
WITH cte AS (
SELECT m.MaterialId, m.MaterialTitle, se.EventDateTime, c.ChannelName,
ROW_NUMBER() OVER (PARTITION BY m.MaterialId ORDER BY EventDateTime ASC) AS rn
FROM GB_Material m
LEFT OUTER JOIN SP_ScheduleEvent se on se.MaterialName = m.MaterialName
LEFT OUTER JOIN SP_Schedule s on s.ScheduleID = se.ScheduleID
LEFT OUTER JOIN GB_Channel c on c.ChannelID = s.ChannelID
WHERE LOWER(m.MaterialName) like '%foo%' OR LOWER(m.MaterialTitle) like '%foo%'
AND se.EventDateTime > GETDATE()
)
SELECT * FROM cte
WHERE rn=1
I have this query which returns qty in each of my branch. now the branch has two WH_subType as you see in the attached diagram i have attached. I want to sum the 2 subtype and show its available qty. how can i do it.
my select query is like this
SELECT
dbo.WarehouseType.name AS Section,
dbo.WarehouseSubType.name AS WH_Type,
dbo.WarehouseSubType1.name AS WH_SubType,
dbo.Branch.name AS Branch,

dbo.Supplier
ON
(
dbo.FinishProduct.supplierId = dbo.Supplier.tafsilId)
WHERE
WarehouseSubType1.warehouseSubTypeId IN (1,4)
group by dbo.WarehouseProductQuantity.tafsilId
Have you tried a group by
SELECT SubType, SUM(qty) AS QtySum
GROUP BY SubType
Every grouped by column should be in your select. Note: for every column you group by it further sub divides the data
Update based on OP comment:
If you want other columns you need to do something like
SELECT s.WH_SubType,s.AvailQty, t.other_cols
from
(SELECT
dbo.WarehouseSubType1.name AS WH_SubType,
sum(dbo.WarehouseProductQuantity.actualQuantity - dbo.WarehouseProductQuantity.reservedQuantity) AS AvailQty
FROM
table
GROUP BY
dbo.WarehouseSubType1.name) s
left join table t on t.dbo.WarehouseSubType1.name = s.WH_SubType;
For reference see this question: How do I use "group by" with three columns of data?
UPDATE 2:
SELECT
dbo.WarehouseType.name AS Section,
dbo.WarehouseSubType.name AS WH_Type,
dbo.WarehouseSubType1.name AS WH_SubType,
dbo.Branch.name AS Branch,
SumTable.AvailQty,
SumTable.Tafsil,
dbo.Tafsil.description AS Product_Name
FROM
dbo.WarehouseSubType
INNER JOIN
dbo.WarehouseType
ON
(
dbo.WarehouseSubType.warehouseTypeId = dbo.WarehouseType.id)
INNER JOIN

dbo.WarehouseSubType.id = dbo.WarehouseSubType1.warehouseSubTypeId)
INNER JOIN

FROM
dbo.WarehouseProductQuantity
group by dbo.WarehouseProductQuantity.tafsilId) SumTable on dbo.Tafsil.id = SumTable.Tafsil
WHERE

You need to do something like
SELECT SUM(AvailQty), ... FROM ... WHERE ... GROUP BY WH_SubType
