I am using left join as a result everything should come from my left table but only matching data coming. I am not able to understand what is wrong in my query or what is missing in it. so please have a look at sample code where anyone can run and reproduce the issue.

Please guide me which area i should rectify to get the desired output.
Solved this way comment this line /WHERE AA.Ticker = 'ADS'/
Now right data is coming.

I'm trying to populate a column in a table with a string of concatenated values from a column in another table. There are numerous solutions suggested, such as How to concatenate text from multiple rows into a single text string in SQL Server, which has 47 answers, but none of them are working for me.
Table #tbl1:
DECLARE #tbl1 TABLE ([Id] INT, [Value] VARCHAR(10))
INSERT INTO #tbl1 ([Id]) VALUES (1),(2),(3)
[Id] [Value]
1 NULL
2 NULL
3 NULL
Table #tbl2:
DECLARE #tbl2 TABLE ([Id] INT, [Value] VARCHAR(10))
INSERT INTO #tbl2 ([Id],[Value]) VALUES (1,'A'),(3,'B'),(1,'C'),(2,'D'),(2,'E'),(3,'F'),(1,'G')
[Id] [Value]
1 A
3 B
1 C
2 D
2 E
3 F
1 G
I'm seeking the syntax to update the records in table #tbl1 to this:
[Id] [Value]
1 ACG
2 DE
3 BF
This doesn't work:
UPDATE [t1]
SET [t1].[Value] = COALESCE([t1].[Value],'') + [t2].[Value]
FROM #tbl1 AS [t1]
LEFT JOIN #tbl2 AS [t2] ON [t1].[Id] = [t2].[Id]
Result:
[Id] [Value]
1 A
2 D
3 B
This syntax produces the same result:
UPDATE [t1]
SET [t1].[Value] = [t2].[Val]
FROM #tbl1 AS [t1]
OUTER APPLY (
SELECT COALESCE([tb2].[Value],[t1].[Value]) AS [Val]
FROM #tbl2 AS [tb2]
WHERE [tb2].[Id] = [t1].[Id]
) AS [t2]
Changing SET to SELECT (below), as in most of the accepted answers, results in the error messages Invalid object name 't1' and Incorrect syntax near 'SELECT'. Expecting SET.
UPDATE [t1]
SELECT [t1].[Value] = COALESCE([t1].[Value],'') + [t2].[Value]
FROM #tbl1 AS [t1]
LEFT JOIN #tbl2 AS [t2] ON [t1].[Id] = [t2].[Id]
My experiments with XML PATH, based upon other Stack Overflow responses (How to concatenate text from multiple rows into a single text string in SQL Server), also produce syntax errors or incorrect results.
Can someone offer the correct syntax?
You have to group the rows, use string_agg to get the values together, and then run the update:
select ##version;DECLARE #tbl1 TABLE ([Id] INT, [Value] VARCHAR(10))
INSERT INTO #tbl1 ([Id]) VALUES (1),(2),(3)
DECLARE #tbl2 TABLE ([Id] INT, [Value] VARCHAR(10))
INSERT INTO #tbl2 ([Id],[Value]) VALUES (1,'A'),(3,'B'),(1,'C'),(2,'D'),(2,'E'),(3,'F'),(1,'G')
;with grouped_data as (
select tbl1.Id, STRING_AGG(tbl2.[Value], '') as value_aggregated
from #tbl1 tbl1
inner join #tbl2 tbl2 on tbl1.Id=tbl2.Id
group by tbl1.id
)
update tbl1 set [Value]=value_aggregated
from #tbl1 tbl1
inner join grouped_data gd on gd.Id=tbl1.id
select * from #tbl1
You can check it running on this DB Fiddle
I have a scenario where almost all of the tables have issues with the PK value as follows. This results is a database error or the violation of the PK insert.
When using the DBCC CheckIdent it displays an inconsistency between the next value and the current one.
Can anyone have a reason for the mismatch happening on several tables?
Since this database is then replicate, I'm afraid this error will propagate across the environment.
I adapted this script to fix it, but really trying to figure out the root of the problem.

As simple as this:

I need to get a tree of related nodes given a certain node, but not necessary top node. I've got a solution using two CTEs, since I am struggling to squeeze it all into one CTE :). Might somebody have a sleek solution to avoid using two CTEs? Here is some code that I was playing with:
DECLARE #temp AS TABLE (ID INT, ParentID INT)
INSERT INTO #temp
SELECT 1 ID, NULL AS ParentID
UNION ALL
SELECT 2, 1
UNION ALL
SELECT 3, 2
UNION ALL
SELECT 4, 3
UNION ALL
SELECT 5, 4
UNION ALL
SELECT 6, NULL
UNION ALL
SELECT 7, 6
UNION ALL
SELECT 8, 7
DECLARE #startNode INT = 4
;WITH TheTree (ID,ParentID)
AS (
SELECT ID, ParentID
FROM #temp
WHERE ID = #startNode
UNION ALL
SELECT t.id, t.ParentID
FROM #temp t
JOIN TheTree tr ON t.ParentID = tr.ID
)
SELECT * FROM TheTree
;WITH Up(ID,ParentID)
AS (
SELECT t.id, t.ParentID
FROM #temp t
WHERE t.ID = #startNode
UNION ALL
SELECT t.id, t.ParentID
FROM #temp t
JOIN Up c ON t.id = c.ParentID
)
--SELECT * FROM Up
,TheTree (ID,ParentID)
AS (
SELECT ID, ParentID
FROM Up
WHERE ParentID is null
UNION ALL
SELECT t.id, t.ParentID
FROM #temp t
JOIN TheTree tr ON t.ParentID = tr.ID
)
SELECT * FROM TheTree
thanks
Meh. This avoids using two CTEs, but the result is a brute force kludge that hardly qualifies as "sleek" as it won’t be efficient if your table is at all sizeable. It will:
Recursively build all possible hierarchies
As you build them, flag the target NodeId as you find it
Return only the targeted tree
I threw in column “TreeNumber” on the off-chance the TargetId appears in multiple hierarchies, or if you’d ever have multiple values to check in one pass. “Depth” was added to make the output a bit more legible.
A more complex solution like #John’s might do, and more and subtler tricks could be done with more detailed table sturctures.
DECLARE #startNode INT = 4
;WITH cteAllTrees (TreeNumber, Depth, ID, ParentID, ContainsTarget)
AS (
SELECT
row_number() over (order by ID) TreeNumber
,1
,ID
,ParentID
,case
when ID = #startNode then 1
else 0
end ContainsTarget
FROM #temp
WHERE ParentId is null
UNION ALL
SELECT
tr.TreeNumber
,tr.Depth + 1
,t.id
,t.ParentID
,case
when tr.ContainsTarget = 1 then 1
when t.ID = #startNode then 1
else 0
end ContainsTarget
FROM #temp t
INNER JOIN cteAllTrees tr
ON t.ParentID = tr.ID
)
SELECT
TreeNumber
,Depth
,ID
,ParentId
from cteAllTrees
where TreeNumber in (select TreeNumber from cteAllTrees where ContainsTarget = 1)
order by
TreeNumber
,Depth
,ID
Here is a technique where you can select the entire hierarchy, a specific node with all its children, and even a filtered list and how they roll.
Note: See the comments next to the DECLAREs

Declare #Top int = null --<< Sets top of Hier Try 2
Declare #Nest varchar(25) = '|-----' --<< Optional: Added for readability
Declare #Filter varchar(25) = '' --<< Empty for All or try 4,6

Compare rows within same table in SQL Server 2012.
Given a table (see script below), what would be the best way to compare rows (individual columns) within the same table?
Example
We are importing data from a client and this can be done many times and we should be able to detect the difference in column's values.
So each time we get the data and we import it we increment our "DataCut" column and then I should be able to compare the difference between datacuts.
If you notice in my sample data in datacutId 3 the Name-Postcode-Homephone have changed.
How would I report on these differences? Any snippet sql or line of thoughts?
Many thanks

This is my T-SQL
select Id,Profile,Type ,
case Profile
when 'Soft' then 'SID'
when 'Hard' then 'HID'
end as [Profile]
from ProductDetail p1
inner join [tableA or tableB] on xxxxxxxx
I want join tableA when Profile = Soft and join tableB when Profile = Hard, how can I do just only using T-SQL in one batch?
Thanks
You can't directly do it, but could achieve the same effect with outer joins
select Id,Profile,Type ,
case Profile
when 'Soft' then 'SID'
when 'Hard' then 'HID'
end as [Profile]
from ProductDetail p1
left outer join tableA ON tableA.x = p1.x AND p1.Profile = 'Soft'
left outer join tableB ON tableB.x = p1.x AND p1.Profile = 'Hard'
where
where
(tableA.x IS NOT NULL and p1.Profile = 'Soft')
or (tableB.x IS NOT NULL and p1.Profile = 'Hard')
Of course, you can choose different tables for inner join operation, but it must be based on some condition or variable.
For Example:
select Id,Profile,Type ,
case Profile
when 'Soft' then 'SID'
when 'Hard' then 'HID'
end as [Profile]
from ProductDetail p1
inner join tableA A
on Profile='Soft'
AND <any other Condition>
UNION
select Id,Profile,Type ,
case Profile
when 'Soft' then 'SID'
when 'Hard' then 'HID'
end as [Profile]
from ProductDetail p1
inner join tableB B
on Profile='Hard'
AND <any other Condition>
You can do this in a single statement with the same or similar case statement in your join. Below is sample code using temp tables that joins to 2 different reference tables merged into a single result set using a UNION
DECLARE #ProductDetail TABLE (Id INT, sProfile VARCHAR(100), StID INT, HdID INT)
DECLARE #TableA TABLE (StId INT, Field1 VARCHAR(100))
DECLARE #TableB TABLE (HdId INT, Field1 VARCHAR(100))
INSERT INTO #ProductDetail (Id, sProfile, StID , HdID ) VALUES (1,'Soft',1,1)
INSERT INTO #ProductDetail (Id, sProfile, StID , HdID ) VALUES (2,'Hard',2,2)
INSERT INTO #TableA (StId,Field1) VALUES (1,'Soft 1')
INSERT INTO #TableA (StId,Field1) VALUES (2,'Soft 2')
INSERT INTO #TableB (HdId,Field1) VALUES (1,'Hard 1')
INSERT INTO #TableB (HdId,Field1) VALUES (2,'Hard 2')
SELECT
p1.Id,p1.sProfile,
CASE
WHEN p1.sProfile = 'Soft' THEN StID
WHEN p1.sProfile = 'Hard' THEN HdId
END AS [Profile]
,ReferenceTable.FieldName
FROM
#ProductDetail p1
INNER JOIN
(
SELECT StID AS id, 'Soft' AS sProfile, Field1 AS FieldName
FROM #TableA AS tableA
UNION ALL
SELECT HdID AS id, 'Hard' AS sProfile, Field1 AS FieldName
FROM #TableB AS tableB
)
AS ReferenceTable
ON
CASE
WHEN p1.sProfile = 'Soft' THEN StID
WHEN p1.sProfile = 'Hard' THEN HdID
END = ReferenceTable.Id
AND p1.sProfile = ReferenceTable.sProfile
This will return the following result set:
Id sProfile Profile FieldName
1 Soft 1 Soft 1
2 Hard 2 Hard 2
