I want to get all data from 2 table based on userID=user1
from parent and child table as i shown in below image
I think this should work:
SELECT parent.CommentID as CommentID,
parent.userID as userID,
parent.Message as Message,
parent.Date as date,
NULL as ParentCommentID
FROM #ParentComment parent
WHERE UserID = 'user1'
UNION
SELECT child.c_commentID as CommentID,
child.c_userID as userID,
child.c_message as Message,
child.c_Date as date,
child.c_parentcommentID as ParentCommentID
FROM #ChildComment child
WHERE child.c_userID = 'user1'
Here's an SQL fiddle : http://sqlfiddle.com/#!9/3bb46/2
Hope this helps!!!
Use Join
Inner join if the id always match
select
a.CommentID as CommentI
,a.userID, as userID
, a.Message as Message
, a.Date as date
, b.c_commentID as parent__comment_id
from parent_comment as a
inner join child_comment as b on a.commentID = b.c_commentID
left join if not always match
select
a.CommentID as CommentI
,a.userID, as userID
, a.Message as Message
, a.Date as date
, b.c_commentID as parent__comment_id
from parent_comment as a
left join child_comment as b on a.commentID = b.c_commentID
Just use Left join with union like this example
Select TP.*
FROM ParentTable as TP LEFT JOIN ChildTable as TC
ON TC.c_ParentcommentID = TP.commentID AND TC.c_ParentcommentID = null
WHERE TP.userID='user1'
UNION ALL
Select TC.c_CommnetID as CommentID , TC.c_userID as userID , TC.c_Message as Message , TC.Date as 'Date'
FROM ChildTable as TC inner join ParentTable as TP
ON TC.c_ParentcommentID = TP.commentID
WHERE TC.userID='user1'

I am trying to add a temp table to my query so that I can query that temp table, I have searched the internet but I couldn't get a solution.
this is my query
;WITH cte AS (
SELECT ID, g.Name
FROM game.Game g WITH(NOLOCK
WHERE ID IN (SELECT Data FROM system.Split(1, ','))
UNION ALL
SELECT g.ID, g.Name
FROM game.Game g WITH(NOLOCK)
JOIN cte ON g.ParentID = cte.ID
)
SELECT c.ID,
c.Name
FROM cte c
INNER JOIN list.Type gt WITH(NOLOCK) ON c.TypeId = gt.TypeID
WHERE c.ID NOT IN (SELECT Data FROM system.Split(1, ','))
AND c.ID IN (SELECT ID FROM game.code WITH(NOLOCK)
WHERE ID = c.ID
AND StatusCode IN ('OP', 'CL', 'SU')
AND isDisplay = 'True'
AND GETDATE() BETWEEN DisplayStart AND DisplayEnd
AND GETDATE() < ISNULL(ResultDateTime, ResultExpected)
)
which gives me the following when I run it
ID | Name
1111 | BaseBall
2222 |BasketBall
45896 |Relay
now I tried to create a temp table as follows
Create Table #temp(
ID int,
Name varchar
)
;WITH cte AS (
SELECT ID, g.Name
FROM game.Game g WITH(NOLOCK)
WHERE ID IN (SELECT Data FROM system.Split(1, ','))
UNION ALL
SELECT g.ID, g.Name
FROM game.Game g WITH(NOLOCK)
JOIN cte ON g.ParentID = cte.ID
)
insert into #temp // i wanted to set these values in the temp table
SELECT c.ID,
c.Name
FROM cte c
INNER JOIN list.Type gt WITH(NOLOCK) ON c.TypeId = gt.TypeID
WHERE c.ID NOT IN (SELECT Data FROM system.Split(1, ','))
AND c.ID IN (SELECT ID FROM game.code WITH(NOLOCK)
WHERE ID = c.ID
AND StatusCode IN ('OP', 'CL', 'SU')
AND isDisplay = 'True'
AND GETDATE() BETWEEN DisplayStart AND DisplayEnd
AND GETDATE() < ISNULL(ResultDateTime, ResultExpected)
)
every time I try to store this information in the temp table it gives me an error 'Column name or number of supplied values does not match table definition.' But I only have two values in. What am I doing wrong that I cant see?
First, why not just use select into?
IF OBJECT_ID('TempDB..#temp') IS NOT NULL
BEGIN
DROP TABLE #temp
END
select c.ID, c.Name
into #temp
from . . .
Then you don't need to define #temp as a table.
Next, your definition is bad, because Name has only one character. This would be fixed with select into.
However, I don't know why you are getting the particular error you are getting. The numbers of columns appears to match.
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 am working with the below query
SELECT * FROM
(SELECT DISTINCT
a.Number
,a.Description
,ISNULL(temp.Quantity,0) Quantity
,LastReceived
,LastIssued
FROM Article a
LEFT JOIN (
select ss.ArticleId
, ss.Quantity
, max(lastreceiveddate) as LastReceived
, max(lastissueddate) as LastIssued
from StockSummary ss
where ss.UnitId = 8
group by ss.ArticleId, ss.StockQuantity
having (MAX(ss.LastReceivedDate) < '2014-09-01' or MAX(ss.LastReceivedDate) is NULL)
AND (MAX(ss.LastIssuedDate) < '2014-09-01' or MAX(ss.LastIssuedDate) is NULL)
) temp on a.Id = temp.ArticleId
WHERE a.UnitId = 8
) main
ORDER BY main.Number
What i want to achieve is to select the articles only with the MAX(ss.LastReceivedDate) and MAX(ss.LastIssuedDate) condition in the Left join query and then do the Quantity Select in the main query.
Note: the quantity column can be 0 or NULL.
Kindly help
I Have a table which holds date but I need to know the latest date where a condition is true per location, only issue is once I add a column called 'notes' it breaks the query and returns too many rows, current query is ...
SELECT
Location,
MAX(date) AS date,
type,
notes
FROM NotesTable a
INNER JOIN Location b on a.LocationID = b.LocationID
INNER JOIN Type c on a.typeid = c.typeid
WHERE typeid <> 8
GROUP BY Location, type, notes
If I comment out the notes column then it works fine but as soon as I add that to the grouping it then returns more rows than required.
Have tried using a subquery but still cant get it working, subquery below
SELECT
r.location,
r.date,
r.type,
t.notes
FROM (SELECT Location, MAX(date), type
FROM NotesTable a INNER JOIN Location b on a.LocationID = b.LocationID
INNER JOIN Type c on a.typeid = c.typeid
WHERE typeid <> 8
GROUP BY location,type
) r
INNER JOIN NotesTable t ON t.date = r.date
Anyone got any other suggestions?
select * from
(
SELECT Location,Date, Type, Notes, Row_Number() Over (Partition By Location, Type order by date desc) RN
FROM
NotesTable a
INNER JOIN Location b on a.LocationID = b.LocationID
INNER JOIN Type c on a.typeid = c.typeid
WHERE typeid <> 8
) v
WHERE rn = 1
Your query is almost correct, you need to add this additional condition in ON clause
AND
t.location = r.location AND
t.type = r.type
full query,
SELECT r.location
, r.DATE
, r.type
, t.notes
FROM (
SELECT Location
, MAX(DATE) maxDate
, type
FROM NotesTable a
INNER JOIN Location b
ON a.LocationID = b.LocationID
INNER JOIN Type c
ON a.typeid = c.typeid
WHERE typeid <> 8
GROUP BY location
, type
) r
INNER JOIN NotesTable t
ON t.DATE = r.maxDate AND
t.location = r.location AND
t.type = r.type
I have tried a lot to figure how to get the count from two tables with respect to master table
I have three tables
Using these table values I need to get this output..
Tried but could get the desired result

You have to first GROUP BY in subqueries, then JOIN to the main table:
SELECT
a.AttributeId
, COALECSE(cntE, 0) AS cntE
, COALECSE(cntM, 0) AS cntM
FROM
AttributeMaster AS a
LEFT JOIN
( SELECT
AttributeId
, COUNT(*) AS cntE
FROM
EmployeeMaster
GROUP BY
AttributeId
) em
ON em.AttributeId = a.AttributeId
LEFT JOIN
( SELECT
AttributeId
, COUNT(*) AS cntM
FROM
MonthlyDerivedMaster
GROUP BY
AttributeId
) mdm
ON mdm.AttributeId = a.AttributeId
SELECT AttributeId,
(SELECT COUNT(Eid) FROM EmployeeMaster WHERE AttributeMaster.AttributeId = EmployeeMaster.AttributeId) as master_eid,
(SELECT COUNT(Eid) FROM MonthnlyDerivedMaster WHERE AttributeMaster.AttributeId = MonthnlyDerivedMaster.AttributeId) as monthly_eid
FROM AttributeMaster
