I have created a CTE (common table Expression) as follows:
DECLARE #N VARCHAR(100)
WITH CAT_NAM AS (
SELECT ID, NAME
FROM TABLE1
WHERE YEAR(DATE) = YEAR(GETDATE())
)
SELECT #N = STUFF((
SELECT ','''+ NAME+''''
FROM CAT_NAM
WHERE ID IN (20,23,25,30,37)
FOR XML PATH ('')
),1,1,'')
The result of above CTE is 'A','B','C','D','F'
Now I need to check 4 different columns CAT_NAM_1,CAT_NAM_2,CAT_NAM_3,CAT_NAM_4 in the result of CTE and form it as one column like follow:
Select
case when CAT_NAM_1 in (#N) then CAT_NAM_1
when CAT_NAM_2 in (#N) then CAT_NAM_2
when CAT_NAM_3 in (#N) then CAT_NAM_3
when CAT_NAM_4 in (#N) then CAT_NAM_4
end as CAT
from table2
When I'm trying to do the above getting error please help me to do.
If my approach is wrong help me with right one.
I am not exactly sure what you are trying to do, but if I understand the following script shows one possible technique. I have created some table variables to mimic the data you presented and then wrote a SELECT statement to do what I think you asked (but I am not sure).
DECLARE #TABLE1 AS TABLE (
ID INT NOT NULL,
[NAME] VARCHAR(10) NOT NULL,
[DATE] DATE NOT NULL
);
INSERT INTO #TABLE1(ID,[NAME],[DATE])
VALUES (20, 'A', '2021-01-01'), (23, 'B', '2021-02-01'),
(25, 'C', '2021-03-01'),(30, 'D', '2021-04-01'),
(37, 'E', '2021-05-01'),(40, 'F', '2021-06-01');
DECLARE #TABLE2 AS TABLE (
ID INT NOT NULL,
CAT_NAM_1 VARCHAR(10) NULL,
CAT_NAM_2 VARCHAR(10) NULL,
CAT_NAM_3 VARCHAR(10) NULL,
CAT_NAM_4 VARCHAR(10) NULL
);
INSERT INTO #TABLE2(ID,CAT_NAM_1,CAT_NAM_2,CAT_NAM_3,CAT_NAM_4)
VALUES (1,'A',NULL,NULL,NULL),(2,NULL,'B',NULL,NULL);
;WITH CAT_NAM AS (
SELECT ID, [NAME]
FROM #TABLE1
WHERE YEAR([DATE]) = YEAR(GETDATE())
AND ID IN (20,23,25,30,37,40)
)
SELECT CASE
WHEN EXISTS(SELECT 1 FROM CAT_NAM WHERE CAT_NAM.[NAME] = CAT_NAM_1) THEN CAT_NAM_1
WHEN EXISTS(SELECT 1 FROM CAT_NAM WHERE CAT_NAM.[NAME] = CAT_NAM_2) THEN CAT_NAM_2
WHEN EXISTS(SELECT 1 FROM CAT_NAM WHERE CAT_NAM.[NAME] = CAT_NAM_3) THEN CAT_NAM_3
WHEN EXISTS(SELECT 1 FROM CAT_NAM WHERE CAT_NAM.[NAME] = CAT_NAM_4) THEN CAT_NAM_4
ELSE '?' -- not sure what you want if there is no match
END AS CAT
FROM #TABLE2;
You can do a bit of set-based logic for this
SELECT
ct.NAME
FROM table2 t2
CROSS APPLY (
SELECT v.NAME
FROM (VALUES
(t2.CAT_NAM_1),
(t2.CAT_NAM_2),
(t2.CAT_NAM_3),
(t2.CAT_NAM_4)
) v(NAME)
INTERSECT
SELECT ct.NAM
FROM CAT_NAM ct
WHERE ct.ID IN (20,23,25,30,37)
) ct;

hello I would like to find a solution to solve my problem in a single request if possible.
For the moment I take all the records then I go through the lines one by one to eliminate what I don't want.
I have 2 tables : first table with links
the second with the prefered label for the url
the second table must be consulted keeping only the row with maximum priority
priority rules are
the current user then
the user group and finally
everyone.
if the hidden column is true, exclude any reference to the url
here is the expected result.
Unfortunately, I don't see any other solution than to multiply the conditions on several selects and unions.
if you have a idea to solve my problem, thank you in advance for your help
It appears as though you can rely on pref_id for the preference ordering, correct? If so, you could try:
SELECT *
FROM table2
INNER JOIN table1 ON table2.url_id = table1.url_id
QUALIFY ROW_NUMBER() OVER (
PARTITION BY table1.url
ORDER BY pref_id ASC
) = 1
This will partition by the url and then provide only the one with lowest pref_id.
I didn't test this SQL as I wasn't sure which RDBMS you're running on, but I used Rasgo to translate the SQL.
maybe of interest in this tricky query:
select so.*, table1.url from
(select distinct t.url_id,
(select pref_id from table2 s where s.url_id = t.url_id order by "user" is null, "group" is null limit 1) pref_id
from table2 t
where not exists(select 1 from table2 s where s.hide and s.url_id = t.url_id)
) ids
join table2 so on so.pref_id = ids.pref_id
join table1 ON table1.url_id = ids.url_id
order by so.url_id;
here is my solution but i think there is better to do.
in the condition's select, I built a column which gives a level note according to the priorities
DECLARE #CUR_USER VARCHAR(10) = 'ROBERT'
DECLARE #CUR_GROUP VARCHAR(10) = 'DEV'
DECLARE #TABLE1 TABLE (

Simply use an ORDER BY clause that puts the preferred row first. You can use this in the window function ROW_NUMBER and work with this or use a lateral top(1) join with CROSS APPLY.
select *
from urls
cross apply
(
select top(1) *
from labels
where labels.url_id = urls.url_id
where [Group] is not null or [user] is not null or hide is not null
order by
case when [Group] is null then 2 else 1 end,
case when [user] is null then 2 else 1 end,
case when hide is null then 2 else 1 end
) top_labels
order by urls.url_id;
Note : i need the record like this
Scode value
BR 10
DL 7
One method is union all:
select 'br', br from t union all
select 'dl', dl from t union all
select 'AP', ap from t;
In a database that supports lateral joins, I would recommend something like this:
select v.*
from t cross apply
(values ('br', br), ('dl', dl), ('AP', ap)
) v(col, val);
use this query, it is dynamic and working.
CREATE TABLE [dbo].[temp](
[br] [int] NULL,
[dl] [int] NULL,
[ap] [int] NULL,
[hp] int null,
[kl] int null,
[mh] int null,
[py] int null
)
insert into temp values(10,7,7,7,8,8,0)
--Drop Table if exists #temp2
--drop table if exists #temp
create table #temp2(id int identity primary key,Scode varchar(10),value int)
declare #col varchar(max),#count int,#intcount int=1,#strquery varchar(max),#id int
select ROW_NUMBER() over (order by column_id) as RN,name into #temp from sys.columns where object_id=OBJECT_ID('temp')
select #count=count(1) from #temp
while(#intcount<=#count)
begin
set #strquery=''
set #col=''
set #id=0
select #col=name from #temp where RN=#intcount
set #strquery='select '+#col+' from temp'
insert into #temp2(value)
exec(#strquery)
select #id=SCOPE_IDENTITY()
update #temp2 set [Scode]=#col where id=#id
set #intcount=#intcount+1
end
select * from temp
select Scode,value from #temp2

You could also use CROSS APPLY with UNION ALL to convert the columns:
select id, br,
dl,
ap
from yourtable
cross apply
(
select 'br', Indicator1 union all
select 'dl', Indicator2 union all
select 'ap', Indicator3
) c (indicatorname, indicatorvalue);
My database has a column named Group.
This Group can be one of two values:
Group101 = Main group
Group101D1 = Subgroup
Every group has two options like this.
But I have some situations where Group101D1 exists but Group101 does not.
Now I want to create an insert where I search for groups with D1 that doesn't have a main group. for example I have Group105D1 but don't have Group105. I want an insert to create a row with Group105.
This is as far as I have come:
INSERT INTO (Group)
SELECT [Table1].[Group], [Table2].[Group]
FROM [Table] Table1
INNER JOIN [Table] Table2 ON [table1].[Group] = [Table2].[Group]
-- WHERE [Table2].[Group] LIKE '%D1'
-- AND [Table1].[Group] NOT LIKE '%D1'
Can some of you please help, I don't know how to finish this.
I know I probably need to use inner join, replace and a where not clause.
You will need replace Also query should exclude rows already exists
Sample data:
DECLARE #groups TABLE ([Group] VARCHAR(100), description VARCHAR(100))
INSERT #groups ([Group], description)
SELECT 'Group101', 'Something1'
UNION ALL
SELECT 'Group101d1', 'Something1'
UNION ALL
SELECT 'Group105d1', 'description_Bleh'
UNION ALL
SELECT 'Group2054', 'desc_2054'
UNION ALL
SELECT 'Group2054d1', 'desc_2054'
Use replace function and exclude Maingroup if it exists
SELECT Replace([group], 'd1', '') [Group], description
FROM #groups
WHERE [Group] NOT IN (
SELECT p.[Group]
FROM #groups g
INNER JOIN #groups p
ON g.[Group] = replace(p.[Group], 'd1', '')
)
Result:
Group description
Group105 description_Bleh
If all subgroups ends with "D1" you can use below query to insert missing main groups.
INSERT INTO (Group)
SELECT
left(subtable.Group,(len(subtable.Group)-len('D1')))
FROM
[Table1].[Group] subtable
where
charindex ( 'D1', subtable.Group) > 0 -- if it is sub-record
and
not exists --check if main group exists
(SELECT
1
FROM
[Table1].[Group] main
where (charindex ( main.Group+'D1', subtable.Group) != 0)
)
Stuff you have already just packaged with data
DECLARE #groups TABLE (grp VARCHAR(100), description VARCHAR(100));
INSERT #groups (grp, description) values
('Group101', 'Something1')
, ('Group101d1', 'Something1')
, ('Group105d1', 'description_Bleh')
, ('Group106d1', 'description_Bleh6')
, ('Group2054', 'desc_2054')
, ('Group2054d1', 'desc_2054');
select * from #groups order by grp;
insert into #groups
select replace(g1.grp, 'd1', ''), g1.description
from #groups g1
where g1.grp like '%d1'
and not exists ( select 1
from #groups g2
where g2.Grp = replace(g1.grp, 'd1', '')
);
select * from #groups order by grp;
You can use NOT EXISTS and REPLACE to get the desired results like below :
INSERT INTO Table2(Group)
select replace([Group], 'd1', '') from Table1 a
where [Group] like '%d1' and
not exists(
select 1 from Table1 where [group] = replace(a.[Group], 'd1', '')
)
I did it this way in the end!
insert into Table (Group, Description)
select replace(Group,'D1','') , description from Table
where Group like '%D1'
and replace(Group,'D1','') not in (
select Group from Table
where Group like 'Group%' and Group not like '%D1')
I would like to get the desired output marked in green
the data points for each id get put into a single cell
Basically take all the events that have happened with A and attach it in the same order
Use Stuff Function:
DECLARE #tblTest AS Table(
ID INT,
EVENT VARCHAR(5)
)
INSERT INTO #tblTest VALUES
(1,'A'),
(1,'A'),
(1,'C'),
(2,'A'),
(2,'B'),
(2,'C')
SELECT DISTINCT
T1.ID,
STUFF
(
(SELECT '' + convert(varchar(10), T2.EVENT, 120)
FROM #tblTest T2
where T1.ID = T2.ID
FOR XML PATH (''))
, 1, 0, '') AS EVENT
FROM #tblTest T1
You can use FOR XML:
SELECT DISTINCT
ID,
(SELECT [EVENT] +''
FROM YourTable
WHERE ID = y.ID
FOR XML PATH('')
) as [EVENT]
FROM YourTable y
Output:
ID EVENT
1 AABCD
2 AABBCC
You can use UDF to do so as follows:
CREATE TABLE t(
id INT,
col CHAR(1)
);
INSERT INTO t VALUES (1,'a');
INSERT INTO t VALUES (1,'b');
INSERT INTO t VALUES (1,'c');
INSERT INTO t VALUES (1,'d');
INSERT INTO t VALUES (2,'e');
INSERT INTO t VALUES (2,'f');
INSERT INTO t VALUES (3,'g');
INSERT INTO t VALUES (4,'h');
The UDF (User defined function) -
USE [t]
GO
CREATE FUNCTION dbo.ConcatenateCols(#Id INT)
RETURNS VARCHAR(MAX)
AS
BEGIN
DECLARE #RtnStr VARCHAR(MAX)
SELECT #RtnStr = COALESCE(#RtnStr + '','') + col
FROM dbo.t
WHERE id = #Id AND col > ''
RETURN #RtnStr
END
GO
Finally the query and result:
SELECT id, dbo.ConcatenateCols(id) AS Cols -- UDF - ConcatenateCols(id)
FROM t GROUP BY Id
CREATE TABLE #temp(Id INt,Event Nvarchar(25))
INSERT INTO #temp
SELECT 1,
'A'
UNION ALL
SELECT 1,
'A'
UNION ALL
SELECT 1,
'B'
UNION ALL
SELECT 1,
'C'
UNION ALL
SELECT 1,
'D'
UNION ALL
SELECT 2,
'A'
UNION ALL
SELECT 2,
'A'
UNION ALL
SELECT 2,
'B'
UNION ALL
SELECT 2,
'B'
UNION ALL
SELECT 2,
'C'
UNION ALL
SELECT 2,
'C'
SELECT DISTINCT ID,
(SELECT [EVENT] +''
FROM #temp
WHERE ID = y.ID
FOR XML PATH('') ) AS [EVENT]
FROM #temp y
I have an issue I just can't get my head around. I know what I want, just simply can't get it out on the screen.
What I have is a table looking like this:
Id, PK UniqueIdentifier, NotNull
Name, nvarchar(255), NotNull
ParentId, UniqueIdentifier, Null
ParentId have a FK to Id.
What I want to accomplish is to get a flat list of all the id's below the Id I pass in.
example:
1 TestName1 NULL
2 TestName2 1
3 TestName3 2
4 TestName4 NULL
5 TestName5 1
The tree would look like this:
-1
-> -2
-> -3
-> -5
-4
If I now ask for 4, I would only get 4 back, but if I ask for 1 I would get 1, 2, 3 and 5.
If I ask for 2, I would get 2 and 3 and so on.
Is there anyone who can point me in the right direction. My brain is fried so I appreciate all help I can get.
declare #T table(
Id int primary key,
Name nvarchar(255) not null,
ParentId int)
insert into #T values
(1, 'TestName1', NULL),
(2, 'TestName2', 1),
(3, 'TestName3', 2),
(4, 'TestName4', NULL),
(5, 'TestName5', 1)
declare #Id int = 1
;with cte as
(
select T.*
from #T as T
where T.Id = #Id
union all
select T.*
from #T as T
inner join cte as C
on T.ParentId = C.Id
)
select *
from cte
Result
Id Name ParentId
----------- -------------------- -----------
1 TestName1 NULL
2 TestName2 1
5 TestName5 1
3 TestName3 2
Here's a working example:
declare #t table (id int, name nvarchar(255), ParentID int)
insert #t values
(1, 'TestName1', NULL),
(2, 'TestName2', 1 ),
(3, 'TestName3', 2 ),
(4, 'TestName4', NULL),
(5, 'TestName5', 1 );
; with rec as
(
select t.name
, t.id as baseid
, t.id
, t.parentid
from #t t
union all
select t.name
, r.baseid
, t.id
, t.parentid
from rec r
join #t t
on t.ParentID = r.id
)
select *
from rec
where baseid = 1
You can filter on baseid, which contains the start of the tree you're querying for.
Try this:
WITH RecQry AS
(
SELECT *
FROM MyTable
UNION ALL
SELECT a.*
FROM MyTable a INNER JOIN RecQry b
ON a.ParentID = b.Id
)
SELECT *
FROM RecQry
Here is a good article about Hierarchy ID models. It goes right from the start of the data right through to the query designs.
Also, you could use a Recursive Query using a Common Table Expression.
I'm guessing that the easiest way to accomplish what you're looking for would be to write a recursive query using a Common Table Expression:
