With the below function I getting the result as 00:09:10 however I want the result to be as 01:00:10.
So hours is considered as considered as 1 day.
Example if hours is 30 then it will be 03:03:00 and so on

I want to insert a dynamic number of rows into a table, based on information in that table.
I can do it using the code below, but I'm wondering if there's a way to avoid the loop.
The commented out section was my best attempt at what I was trying to do, but it gave me an error of:
"The reference to column "iCount" is not allowed in an argument to a TOP, OFFSET, or FETCH clause. Only references to columns at an outer scope or standalone expressions and subqueries are allowed here."

In response to your comment, here is how you would use another cte to generate the full list of dates that you would need, if you havn't got a Dates reference table already (These are tremendously useful):
declare #MinDate date = (select min(TDate) from #TableX);
declare #MaxDate date = (select max(TDate) from #TableX);
with Dates as
(
select #MinDate as DateValue
union all
select dateadd(d,1,DateValue)
from Dates
where DateValue < #MaxDate
)
select DateValue
from Dates
option (maxrecursion 0);
Disclaimer: I'm dealing with a rather old legacy system so any comments telling me about poor design are redundant, although I do genuinely appreciate any such sentiment. There is a new version that solves most legacy problems but we still have to maintain the old system, so basically, we have to manage for now.
I have a table that looks like this (yes, that is a single column, I know):
And I need a view (for reporting purposes) that will dynamically process the data in said table and return this:
The values are \n-delimited (shudder) and you can assume there will always be the same number of values in each cell (9 in the example, although other databases could have 4 or 12 or any number), although I suppose having NULL-insertion in the event of missing values couldn't hurt. They will also always be in a matching order (as in the example, 'AUD', 'Australian Dollar', and '$' are all the first values in their respective cells, and so on).
I've found various approaches to splitting a single cell out into a view, but nothing that covers merging data in such a way as I require. Sitting at home with a cold has not helped my research capabilities. Help me StackOverflow, you're my only hope!
Bonus points for tidy, relatively readable SQL examples, although I'm anticipating messiness as a natural by-product of the hackish nature of my required solution.
Something like this. I didn't take the time to build out the tables, but it should be fairly obvious where you can replace my variables with your rows. You will also want to do a replace char(10) where I have used commas. You could package it up in a table valued function and then call as a view.

You can run this as a single script in SSMS for verification that it works. No schema necessary.

cross apply dbo.DelimitedSplit8K(data.Currencies,char(10)) c

pivot (max(Item) for Col in (Code,Name,Symbol)) pvt
group by ItemNumber
to give us:

Let us say I have some data I would like to repeat N times. A naive approach would be this:
IF OBJECT_ID('dbo.Data', 'U') IS NOT NULL
DROP TABLE dbo.Data
CREATE TABLE Data
(
DataId INT NOT NULL PRIMARY KEY,
DataValue NVARCHAR(MAX) NOT NULL
)
INSERT INTO Data (DataId, DataValue)
SELECT 1, 'Value1' UNION ALL
SELECT 2, 'Value2' UNION ALL
SELECT 3, 'Value3' UNION ALL
SELECT 4, 'Value4' UNION ALL
SELECT 5, 'Value5'
DECLARE #RowsRequired INT
DECLARE #Counter INT
DECLARE #NumberOfRows INT
SET #RowsRequired = 22
IF OBJECT_ID('tempdb..#TempData') IS NOT NULL DROP TABLE #TempData
CREATE TABLE #TempData
(
Id INT IDENTITY(1,1),
DataValue NVARCHAR(MAX)
)
SELECT #NumberOfRows = COUNT(*) FROM Data
SET #Counter = 1
WHILE #RowsRequired > 0
BEGIN
INSERT INTO #TempData
SELECT DataValue FROM Data WHERE DataId = #Counter
SET #Counter = #Counter + 1
SET #RowsRequired = #RowsRequired - 1
IF(#Counter > #NumberOfRows)
BEGIN
SET #Counter = 1
END
END
SELECT * FROM #TempData
Here #RowsRequired determines how many rows are required. Could this be rephrased in a set based form? Thanks.
Here is a SQLFiddle with the code.
Try this instead:
DECLARE #RowsRequired INT = 22
;WITH CTE AS
(
SELECT DataId, DataValue, ROW_NUMBER() over (PARTITION BY DataId ORDER BY DataId) sort
FROM DATA
CROSS JOIN
(
SELECT TOP (#RowsRequired) 0 d
FROM master..spt_values
) d
)
SELECT TOP (#RowsRequired) ROW_NUMBER() over (order by sort), DataValue
FROM CTE
ORDER BY sort, 1
I tried this and worked for me.
declare #requiredrows int
set #requiredrows = 22;
declare #foreachrow int
select #foreachrow = #requiredrows / Count(*) from Data;
select top (#requiredrows) * from
(
select *, ROW_NUMBER() over(partition by dataId order by number) rno
from Data
Cross Join master..spt_values
) A
where rno <= #foreachrow + 1
Hope it will help.
I have problems with a cursur that’s ends randomly. I want to produce a row for each element , so for every element there is a row for every month in 2012. If there is a row missing for a specific month, it should create that as well.
Now, it’s producing a row for the last element in every month until year 2057.
Now, I have a row for each element until in every month until year 2057 and only for one element in my table.
My table design:
create table tblDataUpdateTest
(
slno int identity(1,1),
cName varchar(50),
cRemarks varchar(50),
[Date] date,
)
insert into tblDataUpdateTest (cName, cRemarks,[Date]) values ('name1','Text1','2012-01-01'),
('name2','Text2','2012-01-01')
My code:
declare #y as int
declare #d as int
SET #y = 2012
SET #d = 1
Declare ##counter int
Declare ##month int
set ##counter=0
Declare ##slno int
Declare ##cRemarks varchar(100)
Declare ##cName varchar(50)
Declare ##Date date
set ##month = 1
Declare tmepTbl cursor
For
Select slno,cName,cRemarks,date from tblDataUpdateTest
Open tmepTbl /* Opening the cursor */
fetch next from tmepTbl
into ##slno,##cName,##cRemarks,##Date
while ##fetch_Status=-1
begin
if not exists (select cRemarks from tblDataUpdateTest where MONTH(Date) = ##month AND YEAR(Date) = 2012)
begin
insert into tblDataUpdateTest (cName, cRemarks,[Date]) values (##cName,'s',(DateAdd(yy, 2012-1900,DateAdd(m, ##month - 1, 01 - 1))))
end
fetch next from tmepTbl
into ##slno,##cName,##cRemarks,##Date
set ##month=##month+1
end
close tmepTbl
Deallocate tmepTbl
My table now
cName cRemarks Date
name1 Text1 2012-01-01
name2 Text2 2012-01-01
I want follwing to happen:
cName cRemarks Date
name1 Text1 2012-01-01

Wouldn't be better to use a recursive CTE, instead of a cursor?
Here is an example:
DECLARE #y INT
DECLARE #m INT
DECLARE #n INT
SET #y = 2012
SET #m = 1
SET #n = 3
;WITH dates(d, m) AS(
SELECT CONVERT(DATE, CONVERT(VARCHAR(4), #y) + '-01-01'), 1
UNION ALL
SELECT CONVERT(DATE, CONVERT(VARCHAR(4), #y) + '-' + CASE WHEN m + 1 < 10 THEN '0' ELSE '' END + CONVERT(VARCHAR(2), m + 1) + '-01')
, m + 1
FROM dates
WHERE m < #n
)
INSERT INTO tblDataUpdateTest(cName, cRemarks,[Date])
SELECT cName, cRemarks, [date] FROM (
SELECT cName, cRemarks, dates.d AS [date]
FROM tblDataUpdateTest
CROSS JOIN dates) t
WHERE NOT(EXISTS(SELECT * FROM tblDataUpdateTest WHERE cName = t.cName AND [date] = t.[date]))
OPTION(MAXRECURSION 11)
SELECT * FROM tblDataUpdateTest ORDER BY cName
