I want to concatenate comma-separated string. I have a query where I am using the function to get the staff.
Currently, I am using [dbo].fn_fullname(A.REFNO) as Staff to get the staff but I want to include some conditions if the count of cast(S.SCH_NO as varchar) as ReferenceIdentifier is greater than 1 then concatenate the value. But not sure how it can be achieved inside the view itself.
Here I am trying to use STUFF to concatenate.
Here is the query:
Alter View vw_TestDB
AS
select
NEWID() as UniqueKey,
P.ID as Number,
cast(S.SCH_NO as varchar) as ReferenceIdentifier,
cast(S.START_D as datetime2) as StartDateTime,
staff = STUFF((
SELECT ',' + [dbo].fn_fullname(A.REFNO)
FROM [dbo].[vw_TESTDB]
FOR XML PATH('')
), 1, 1, '')
FROM [dbo].[vw_TestDB]
group by ReferenceIdentifier
having count(ReferenceIdentifier)>1,
[dbo].fn_fullname(A.REFNO) as Staff,
from [dbo].V_SCHEDULES S WITH (NOLOCK)
inner join [dbo].V_PAT P WITH (NOLOCK) on P.PAT_REFNO = S.PAT_REFNO
Here the function:
ALTER FUNCTION [dbo].[fn_fullname]
(
#refno as numeric(10, 0)
)
RETURNS varchar(100)
AS
BEGIN
DECLARE #name as varchar(100)
SELECT #name = Stuff(Coalesce(' ' +
CASE
WHEN proca.TITLE_REFNO = 3104
THEN NULL
ELSE
NullIf(dbo.fn_rfval(proca.TITLE_REFNO), '')
END,
'') +
Coalesce(' ' + proca.forename, '') +
Coalesce(' ' + proca.surname, ''),
1,
1,
'')
FROM dbo.v_carers_active proca (nolock)
WHERE refno = #refno
return #name
END
GO
Here are sample data

Number
ReferenceIdentifier
StartDateTime

Not quite understand what you wanted. Based on the sample data and expected output, it seems like you wanted
SELECT t.[Number], t.[ReferenceIdentifier], t.[StartDatetime],
STUFF (
(SELECT ',' + [dbo].fn_fullname(x.REFNO)
FROM yourtable AS x
WHERE x.[Number] = t.[Number]
AND x.[ReferenceIdentifier] = t.[ReferenceIdentifier]
AND x.[StartDatetime] = t.[StartDatetime]
FOR XML PATH('')),
1, 1, '') AS Staff
FROM yourtable t
GROUP BY t.[Number], t.[ReferenceIdentifier], t.[StartDatetime]
HAVING COUNT(*) > 1

I am get data from a third party database to generate certain reports. The issue is that it keeps on generating a new table every month to insert the same record in same columns in the following manner:
For December table : Data_12_2019
For January table : Data_1_2020
For February table : Data_2_2020
For March table : Data_3_2020 and so on
and table data is as following:
UserId DLogId LogDate
1461 1799 2020-01-06 09:07:51.000

I want to get data placed in above tables and tables that will be generated in future also.
I am seeking a help about how to do it.
You can achieve this using dynamic query. If your table structure is same, you can try like following.
DECLARE #query AS NVARCHAR(max) = Stuff((SELECT DISTINCT ' ' + 'SELECT * FROM ' + Quotename(name) + ' UNION'
FROM
(
SELECT
[name]
FROM
sys.sysobjects
WHERE
[xtype] = 'U'
and NAME LIKE 'Data_[0-9][0-9]_[0-9][0-9][0-9][0-9]'
)t
FOR xml path(''), type).value('.', 'NVARCHAR(MAX)'), 1, 1, '');
SET #query= substring(#query,0,len(#query)-5)
exec(#query)
Note: Better replace * with the column names you want.
To get all the tables you can use sysobject and filter out based on table names like
SELECT [name]
FROM sys.sysobjects
WHERE [xtype] = 'U'
AND NAME LIKE 'Data_[0-9][0-9]_[0-9][0-9][0-9][0-9]'
And build a dynamic query using UNION.
PREPARE stmt1 FROM ' SELECT GROUP_CONCAT('SELECT * FROM ',TABLE_NAME,' UNION ')
FROM information_schema.tables
WHERE table_schema =? AND table_name LIKE 'Data_%'';
SET #a = 'MyDb';
EXECUTE stmt1 USING #a;
In SQL 2016, I need to create a list using financial periods but only have the from/to available - it's formatted similar to dates but are 0mmyyyy, so the first 3 numbers are the month/period and the last 4 digits the year.
e.g. period_from is '0102017' and period_to '0032018', but trying to bring back a list that includes the ones in between as well?
0102017,
0112017,
0122017,
0012018,
0022018
Also, the first three characters can go to 012 or 013, so need to be able to easily alter the code for other databases.
I am not entirely sure what you are wanting to use this list for, but you can get all your period values with the help of a tally table and some common table expressions.
-- Test data
declare #p table(PeriodFrom nvarchar(10),PeriodTo nvarchar(10));
insert into #p values('0102017','0032018'),('0052018','0112018');
-- Specify the additional periods you want to include, use 31st December for correct sorting
declare #e table(ExtraPeriodDate date
,ExtraPeriodText nvarchar(10)
);
insert into #e values('20171231','0132017');
-- Convert start and end of periods to dates
with m as (select cast(min(right(PeriodFrom,4) + substring(PeriodFrom,2,2)) + '01' as date) as MinPeriod
,cast(max(right(PeriodTo,4) + substring(PeriodTo,2,2)) + '01' as date) as MaxPeriod
from #p
) -- Built a tally table of dates to join from
,t(t) as (select 1 union all select 1 union all select 1 union all select 1 union all select 1 union all select 1 union all select 1 union all select 1 union all select 1 union all select 1)
,d(d) as (select top (select datediff(month,MinPeriod,MaxPeriod)+1 from m) dateadd(m,row_number() over (order by (select null))-1,m.MinPeriod) from m, t t1, t t2, t t3, t t4, t t5)
-- Use the tally table to convert back to your date period text format
,p as (select d.d as PeriodDate
,'0' + right('00' + cast(month(d) as nvarchar(2)),2) + cast(year(d) as nvarchar(4)) as PeriodText
from d
union all -- and add in any of the addition '13th' month periods you specified previously
select ExtraPeriodDate
,ExtraPeriodText
from #e
)
select PeriodText
from p
order by PeriodDate;
Output:
+------------+
| PeriodText |
+------------+
| 0102017 |
| 0112017 |
| 0122017 |
| 0132017 |
| 0012018 |
| 0022018 |
| 0032018 |
| 0042018 |
| 0052018 |
| 0062018 |
| 0072018 |
| 0082018 |
| 0092018 |
| 0102018 |
| 0112018 |
+------------+
If this isn't what you require exactly it should put you on the right path to generating these values either as the result of a function or concatenated together into a list as per your comment by using for xml on the result by changing the final select statement to:
select stuff((select ', ' + PeriodText
from p
order by PeriodDate
for xml path('')
)
,1,2,'') as PeriodTexts;
Which outputs:
+---------------------------------------------------------------------------------------------------------------------------------------+
| PeriodTexts |
+---------------------------------------------------------------------------------------------------------------------------------------+
| 0102017, 0112017, 0122017, 0132017, 0012018, 0022018, 0032018, 0042018, 0052018, 0062018, 0072018, 0082018, 0092018, 0102018, 0112018 |

This is going to be a little complicated. To start, I have a user defined table value function that outputs a calendar table based on a start and end date. You'll want to create that first...
CREATE FUNCTION dbo.udf_calendar (#datestart smalldatetime, #dateend smalldatetime)
RETURNS #calendar TABLE (
[day] int,
[date] smalldatetime
)
AS
BEGIN
DECLARE #rows int
DECLARE #i int = 1
SELECT
#rows = DATEDIFF(DAY, #datestart, #dateend)
WHILE (#i <= #rows)
BEGIN
INSERT INTO #calendar ([day])
VALUES (#i)
SET #i = #i + 1
END
UPDATE a
SET [date] = DATEADD(DAY, [day] - 1, #datestart)
--select *, DATEADD(day,id-1,#datestart)
FROM #calendar a
RETURN
END
Then, the following will give you the output that I THINK you are looking for. I've commented to try and explain how I got there, but it still might be a bit difficult to follow...
--Create temp table example with your period from and to.
IF (SELECT
OBJECT_ID('tempdb..#example'))
IS NOT NULL
DROP TABLE #example
SELECT
'0102017' periodfrom,
'0032018' periodto INTO #example
/*
This is the difficult part. Basically you're inner joining the calendar
to the temp table where the dates are between the manipulated period from and to.
I've added an extra column formatted to allow ordering correctly by period.
*/
SELECT DISTINCT
periodfrom,
periodto,
RIGHT('00' + CAST(DATEPART(MONTH, [date]) AS varchar(50)), 3) + CAST(DATEPART(YEAR, [date]) AS varchar(50)) datefill,
CAST(DATEPART(YEAR, [date]) AS varchar(50)) + RIGHT('00' + CAST(DATEPART(MONTH, [date]) AS varchar(50)), 3) datefill2
FROM dbo.udf_calendar('2015-01-01', '2018-12-31') a
INNER JOIN #example b
ON a.[date] BETWEEN SUBSTRING(periodfrom, 2, 2) + '-01-' + SUBSTRING(periodfrom, 4, 4) AND SUBSTRING(periodto, 2, 2) + '-01-' + SUBSTRING(periodto, 4, 4)
ORDER BY datefill2
I used the below query to convert and replace at the same time.
SELECT Isnull(MAX(CONVERT(INT, REPLACE(REPLACE(mycolum,'234 hyd'+' ', ''), 'c', ''))), 0) + 1
FROM mytable
Ans like :---234 hyd c1, 234 hyd c2, 234 hyd c3 ......
Try this query below. It selects the number from the centername and after that it adds the villigename and the prefix.
SELECT CASE WHEN #maxcount IS NULL
THEN CONCAT(MAX(CAST(CenternameA AS INT)) +1, #villagename, ' ', #prefix)
FROM(
SELECT (SUBSTRING(centername, PATINDEX('%[0-9.-]%', centername), 8000),
PATINDEX('%[^0-9.-]%', SUBSTRING(centername, PATINDEX('%[0-9.-]%', centername), 8000) AS CenternameA
FROM centermastertable
WHERE villageid = #villageid
)
Please note it only works in sql server 2012 or higher.
The code to select the number can be found here
I have a PIVOT situation.
Source table columns:
Title Description Datetime RecordsCount
A California 2015-07-08 10:44:39.040 5
A California 2015-07-08 12:44:39.040 6
A California 2015-05-08 15:44:39.040 3
B Florida 2015-07-08 16:44:39.040 2
B Florida 2015-05-08 19:44:39.040 4
Now I need this pivoted as
2015-07-08 2015-05-08
Title Description
A California 11 3
B Florida 2 4
if we have two record counts on same dates (no matter of time) then sum them, else display in different column.
Trying to write something like this, but it throws errors.
Select * from #DataQualTest
PIVOT (SUM(RecordCount) FOR DateTime IN (Select Datetime from #DataQualTest) )
AS Pivot_Table
Please help me out with this.
Thanks
Not exactly the word for word solution but this should give you a direction.
create table #tmp
(
country varchar(max)
, date1 datetime
, record int
)
insert into #tmp values ('California', '2010-01-01', 2)
insert into #tmp values ('California', '2010-01-01', 5)
insert into #tmp values ('California', '2012-01-01', 1)
insert into #tmp values ('Florida', '2010-01-01', 3)
insert into #tmp values ('Florida', '2010-01-01', 5)
select * from #tmp
pivot (sum(record) for date1 in ([2010-01-01], [2012-01-01])) as avg
output
country 2010-01-01 2012-01-01
California 7 1
Florida 8 NULL
If you want to be more flexible, you need some pre-processing to get from full timestamps to days (in order for later on the PIVOT's grouping to actually have the anticipated effect):
CREATE VIEW DataQualTestView AS
SELECT
title
, description
, DATEFROMPARTS (DATEPART(yyyy, date_time),
DATEPART(mm, date_time),
DATEPART(dd, date_time)) AS day_from_date_time
, recordsCount
FROM DataQualTest
;
From there you could continue:
DECLARE #query AS NVARCHAR(MAX)
DECLARE #columns AS NVARCHAR(MAX)
SELECT #columns = ISNULL(#columns + ',' , '')
+ QUOTENAME(day_from_date_time)
FROM (SELECT DISTINCT
day_from_date_time
FROM DataQualTestView) AS TheDays
SET #query =
N'SELECT
title
, description
, ' + #columns + '
FROM DataQualTestView
PIVOT(SUM(recordsCount)
FOR day_from_date_time IN (' + #columns + ')) AS Pivoted'
EXEC SP_EXECUTESQL #query
GO
... and would get:
| title | description | 2015-05-08 | 2015-07-08 |
|-------|-------------|------------|------------|
| A | California | 3 | 11 |
| B | Florida | 4 | 2 |

Please comment, if and as this requires adjustment / further detail.
I'm trying to create a query with dynamic columns, based on data from three tables.
This is the database structure:
STUDENT
studentID int,
studentNumber int,
studentName nvarchar(100).
EXAM:
examID int,
examName varchar(100),
examenDate datetime,
EXAM_REGISTRATION:
studentID int,
examID int,
A record is added to the EXAM_REGISTRATION table when a student has registered for an exam.
What I'm trying to get is a list of all the exams and all the students in a pivot table to see which students have registered for which exams, like this:
Quite frankly I don't know where to start.
I can query everything individually and put it all together but how can I combine it into one query?
I've been researching pivot tables, but every example seems to query only from one table and uses numbers and functions like MIN, AVG etc.
Can someone help me along?
ok lets go
some data to play with
create table #student
(studentID int, studentNumber int, studentName nvarchar(100))
create table #exam
(examID int, examName nvarchar(100), examDate datetime)
create table #examReg
(studentID int, examID int)
insert into #student
values (1, 787878, 'pierwszy')
,(2, 89898, 'drugi')
,(3, 343434, 'trzeci')
,(4, 121212, 'czwarty')
insert into #exam
values (1, 'exPierwszy', GETDATE())
,(2, 'exDrugi', GETDATE())
,(3, 'exTrzeci', GETDATE())
insert into #examReg
values (1,2),(1,3)
, (2,2),(2,3)
,(3,1),(3,2)
,(4,1),(4,2),(4,3)
and now the main part, and explanation
first of all you have to get pivot query
select examName, examDate , min([1]) , min([2]), min([3]) ,min([4])--studentID as studentID, examDate --,studentNumber
from
(select a.studentID , studentNumber, examDate, examName
from #student a
join #examReg b on a.studentID = b.studentID
join #exam c on c.examID = b.examID ) as m
pivot
(min(studentNumber) FOR studentID in ([1],[2],[3],[4])) as t
group by examName, examDate
as you have it , just change it select statement and studentID list in pivot declaration, you have to generate those parts dynamicly , so we just copy previously written query and replace columns with our token
declare #sqlTemplate nvarchar(max) =
'select examName, examDate ##sqlColumnList##
from
(select a.studentID , studentNumber, examDate, examName
from #student a
join #examReg b on a.studentID = b.studentID
join #exam c on c.examID = b.examID ) as m
pivot
(min(studentNumber) FOR studentID in (##sqlStudentIDList##)) as t
group by examName, examDate
'
after that you generate column list and studentID list by concatenting strings in tsql
declare #sqlColumnList nvarchar(max) = ''
select #sqlColumnList += ',min([' + cast(studentID as nvarchar(10)) + ']) as [' + studentName +'(' + cast(studentNumber as nvarchar(10)) + ')]'
from #student
declare #sqlStudentIDList nvarchar(max) = ''
select #sqlStudentIDList += '[' + CAST(studentID as nvarchar(10)) + '],'
from #student
set #sqlStudentIDList = SUBSTRING(#sqlStudentIDList, 0, LEN(#sqlStudentIDList))
select #sqlStudentIDList
once you have it , all you have to do is to replace tokens in previous template
set #sqlTemplate = REPLACE(#sqlTemplate, '##sqlColumnList##', #sqlColumnList)
set #sqlTemplate = REPLACE(#sqlTemplate, '##sqlStudentIDList##', #sqlStudentIDList)
select #sqlTemplate
exec sp_executesql #sqlTemplate
and thats it
if you want to read more about pivot go for msdn
if you want to read about dynamic go for this link
edit: to adjust the query for the question from comment you would have to change #sqlColumnList like that
select #sqlColumnList += ',min(' + QUOTENAME(studentID) + ') as Student' + CAST(studentID as nvarchar(10)) + '_REG,
'''+ studentName + ''' as Student' + cast(studentID as nvarchar(10)) + '_NAME,
'+ cast(studentID as nvarchar(10)) + ' as Student' + cast(studentID as nvarchar(10)) + '_ID'
from #student
This is a pivot of the data. I would perform this slightly different than the other answer. If you know all of the values, then you can hard-code the values.
A static version will be:
select examname,
examendate,
IsNull([Smith, John (14323)], 'false') [Smith, John (14323)],
IsNull([Craft, Peter (14334)], 'false') [Craft, Peter (14334)],
IsNull([Davis, Alan (13432)], 'false') [Davis, Alan (13432)],
IsNull([Newman, Ted (133123)], 'false') [Newman, Ted (133123)]
from
(
select e.examname,
e.examenDate,
s.studentName + ' ('+cast(s.studentnumber as varchar(50))+')' studentNameNum,
'true ' as Flag
from exam e
left join exam_registration er
on e.examid = er.examid
right join student s
on er.studentid = s.studentid
) src
pivot
(
max(flag)
for studentNameNum in ([Smith, John (14323)], [Craft, Peter (14334)],
[Davis, Alan (13432)], [Newman, Ted (133123)])
) piv
See SQL Fiddle with Demo
If your values are unknown then the query will be:
DECLARE #cols AS NVARCHAR(MAX),
#colsNull AS NVARCHAR(MAX),
#query AS NVARCHAR(MAX)
select #cols = STUFF((SELECT distinct ',' + QUOTENAME(s.studentName + ' ('+cast(s.studentnumber as varchar(50))+')')
from student s
FOR XML PATH(''), TYPE
).value('.', 'NVARCHAR(MAX)')
,1,1,'')
select #colsNull = STUFF((SELECT distinct ',IsNull(' + QUOTENAME(s.studentName + ' ('+cast(s.studentnumber as varchar(50))+')')+', ''false'')'+' as '+QUOTENAME(s.studentName+' ('+cast(s.studentnumber as varchar(50))+')')
from student s
FOR XML PATH(''), TYPE
).value('.', 'NVARCHAR(MAX)')
,1,1,'')
set #query = 'SELECT examname,
examenDate,' + #colsNull + ' from
(
select e.examname,
e.examenDate,
s.studentName + '' (''+cast(s.studentnumber as varchar(50))+'')'' studentNameNum,
''true '' as Flag
from exam e
left join exam_registration er
on e.examid = er.examid
right join student s
on er.studentid = s.studentid
) x
pivot
(
max(flag)
for studentNameNum in (' + #cols + ')
) p '
execute(#query)
See SQL Fiddle with Demo
The result will be:
| EXAMNAME | EXAMENDATE | CRAFT, PETER (14334) | DAVIS, ALAN (13432) | NEWMAN, TED (133123) | SMITH, JOHN (14323) |
----------------------------------------------------------------------------------------------------------------------------
