I have mart table where i have gaps in rows.I tried using loop condition but I'm unable to proceed
CREATE TABLE Mart
(martID int, mart int)
;
INSERT INTO Mart
(martID, mart)
VALUES
(1, 10),
(4, 12),
(6, 20)
;
OutPut
martID mart
1 10
2 0
3 0
4 12
5 0
6 20
My code so far
select max(martId) as nr
from Mart
union all
select nr - 1
from numbers
where nr > 1
You can use the code below if you just want to display the data:
SELECT
n.MartId,
ISNULL(m.mart, 0)
FROM
numbers n
LEFT JOIN Mart m ON n.MartId = m.martID
ORDER BY
n.MartId
Hope you have Number table contains series of Numbers without gaps. Try this
SELECT nr,
COALESCE(mart, 0) AS mart
FROM numbers n
LEFT OUTER JOIN mart m
ON m.martid = n.nr
WHERE n.nr BETWEEN (SELECT Min(martid)
FROM mart) AND (SELECT Max(martid)
FROM mart)
In case you don't have numbers table then refer this link to generate sequence of values in SQL Server. I will prefer STACKED CTE method
;WITH e1(n) 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
), -- 10
e2(n) AS (SELECT 1 FROM e1 CROSS JOIN e1 AS b), -- 10*10
e3(n) AS (SELECT 1 FROM e1 CROSS JOIN e2) -- 10*100
SELECT n = ROW_NUMBER() OVER (ORDER BY n) FROM e3 ORDER BY n;
may be this works
declare #Mart TABLE

)
select Num,

Try using recursive cte,

I already asked for help on a part of my problem here.
I used to get 10 rows no matter if there are filled or not. But now I'm facing something else where I need to do it multiple times in the same query result.
WITH NUMBERS AS
(
SELECT 1 rowNumber
UNION ALL
SELECT 2
UNION ALL
SELECT 3
UNION ALL
SELECT 4
UNION ALL
SELECT 5
UNION ALL
SELECT 6
UNION ALL
SELECT 7
UNION ALL
SELECT 8
UNION ALL
SELECT 9
UNION ALL
SELECT 10
)
SELECT DISTINCT sp.SLC_ID, c.rowNumber, c.PCE_ID
FROM SELECT_PART sp
LEFT JOIN (
SELECT b.*
FROM NUMBERS
LEFT OUTER JOIN (
SELECT a.*
FROM (
SELECT SELECT_PART.SLC_ID, ROW_NUMBER() OVER (ORDER BY SELECT_PART.SLC_ID) as
rowNumber, SELECT_PART.PCE_ID
FROM SELECT_PART
WHERE SELECT_PART.SLC_ID = (must be the same as sp.SLC_ID and can''t hardcode it)
) a
) b
ON b.rowNumber = NUMBERS.rowNumber
) c ON c.SLC_ID = sp.SLC_ID
ORDER BY sp.SLC_ID, c.rowNumber
It works fine for the first 10 lines, but next SLC_ID only got 1 empty line
I need it to be like that
SLC_ID rowNumer PCE_ID
1 1 0001
1 2 0002
1 3 NULL
1 ... ...
1 10 NULL
2 1 0011
2 2 0012
2 3 0013
2 ... ...
2 10 0020
3 1 0021
3 ... ...
Really need it that way to build a report.
Instead of manually building a query-specific number list where you have to include every possible number you need (1 through 10 in this case), create a numbers table.
DECLARE #UpperBound INT = 1000000;
;WITH cteN(Number) AS
(
SELECT ROW_NUMBER() OVER (ORDER BY s1.[object_id]) - 1
FROM sys.all_columns AS s1
CROSS JOIN sys.all_columns AS s2
)
SELECT [Number] INTO dbo.Numbers
FROM cteN WHERE [Number] <= #UpperBound;
CREATE UNIQUE CLUSTERED INDEX CIX_Number ON dbo.Numbers([Number])
WITH
(
FILLFACTOR = 100, -- in the event server default has been changed
DATA_COMPRESSION = ROW -- if Enterprise & table large enough to matter
);

Alternatively, since you can't add data, use a table that already exists in SQL Server.
WITH NUMBERS AS
(
SELECT DISTINCT Number as rowNumber FROM master..spt_values where type = 'P'
)
SELECT DISTINCT sp.SLC_ID, c.rowNumber, c.PCE_ID
FROM SELECT_PART sp
LEFT JOIN (
SELECT b.*
FROM NUMBERS
LEFT OUTER JOIN (
SELECT a.*
FROM(
SELECT SELECT_PART.SLC_ID, ROW_NUMBER() OVER (ORDER BY SELECT_PART.SLC_ID) as
rowNumber, SELECT_PART.PCE_ID
FROM SELECT_PART
WHERE SELECT_PART.SLC_ID = (must be the same as sp.SLC_ID and can''t hardcode it)
) a
) b
ON b.rowNumber = NUMBERS.rowNumber
) c ON c.SLC_ID = sp.SLC_ID
ORDER BY sp.SLC_ID, c.rowNumber

I have a table called recipes with following data.
page_no title
-----------------
1 pancake
2 pizza
3 pasta
5 cookie
page_no 0 is always blank, and missing page_no are blank, I want output as below, for the blank page NULL values in the result.
left_title right_title
------------------------
NULL pancake
Pizza pasta
NULL cookie
I have tried this SQL statement, but it's not returning the desired output:
SELECT
CASE WHEN id % 2 = 0
THEN title
END AS left_title,
CASE WHEN id %2 != 0
THEN title
END AS right_title
FROM
recipes
You are quite close. You just need aggregation:
select max(case when id % 2 = 0 then title end) as left_title,
max(case when id % 2 = 1 then title end) as right_title
from recipes
group by id / 2
order by min(id);
SQL Server does integer division, so id / 2 is always an integer.
Using CTE.. this should be give you a good CTE overview
DECLARE #table TABLE (
pageno int,
title varchar(30)
)
INSERT INTO #table
VALUES (1, 'pancake')
, (2, 'pizza')

I need to write a stored procedure or table function to return a new data table as a new data source.
I wish to loop through the original table for every 5 rows base on the invoice ID column (it's possible not start from 1), the first 5 rows add to the left of the new table and the second 5 rows add to the right of the new table, the third 5 rows to the left and so on.
For example, Here is the original table:
Here is the expect table:
Thanks in advance!
declare #rowCount int = 5;
with cte as (
select *,( (IN_InvoiceID-1) / #rowCount ) % 2 group1

select * from cte
select T1.INID,T1.IN_InvoiceID,T1.IN_InvoiceAmount,T2.INID,T2.IN_InvoiceID,T2.IN_InvoiceAmount
from CTE T1
left join CTE T2 on T2.group1 = 1 and T1.group2 = T2.group2-1 and T1.group3 = T2.group3
where T1.group1 = 0

Could you please check article Display Data in Multiple Columns using SQL showing with example case how a database developer can show the list of data rows in a columnar mode using Row_Number() function and mode arithmetic expression
You need to add additional columns from the same row that is different in the sample
Seems as if you want to split the table into 2 tables with alternating 5 rows. An easy way to do this would be:
Take data into a temp table having an extra column (lets say
grouping_id)
Update the grouping id so that each 5 rows have the same id. You can
use in_invoiceId % 5 (the nod function). After this step the first 5
rows will have grouping_id 0, next 5 will have 1, next will have 2
(assuming your invoice id is incremented +1 for all rows).
You can just do a normal select with where clause for odd and even grouping_id
Ideally, you can manage with the 2 tables Master and detail table.
But due to my curiosity, I am able to solve and give the answer as
Declare #table table(id int identity, invoice_id int)
; WITH Numbers AS
(
SELECT n = 1
UNION ALL
SELECT n + 1
FROM Numbers
WHERE n+1 <= 50
)
insert into #table SELECT n
FROM Numbers
Select (a.id )%5 ,* from #table a join #table b on a.id+5 = b.id and a.id != b.id
;WITH Numbers AS
(
SELECT n = 1, o = 5
UNION ALL
SELECT n + 10, o = o+10
FROM Numbers
WHERE n+1 <= 50
)
select a.id ParentId,a.invoice_id ParentInvoiceId, --b.n, b.o,
c.invoice_id childInvoiceID from #table a
join Numbers b on a.id between b.n and b.o
left join #table c on a.id + 5 = c.id
Here is my solution
First i create grps based on whether the in_invoiceid is divisible by 5 or not.(Ignore the remainders)
After that i create a category to indicate between alternative groups(ie by checking if the remainder is 0 or otherise)
Then its a matter of dense_ranking the records on the basis of the category field ordered by in_invoiceid
Lastly a join with category=1 rows with same dense_rank as those records in category=0
create table Invoicetable(IN_ID varchar(100), IN_InvoiceID int)
INSERT INTO Invoicetable (IN_ID, IN_InvoiceID)
VALUES
('2345-BCDE-6645-1DDF', 1),
('2345-BCDE-6645-3DDF', 2),

You may try with the following approach. Dividing the table is done with (((ROW_NUMBER() OVER (ORDER BY IN_InvoiceID) - 1) / 5) % 2 = 0) which groups records in left and right groups.
CREATE TABLE #InvoiceTable(
IN_ID varchar(24),
IN_InvoiceID int
)
INSERT INTO #InvoiceTable (IN_ID, IN_InvoiceID)
VALUES
('2345-BCDE-6645-1DDF', 1),
('2345-BCDE-6645-3DDF', 2),
('2345-BCDE-6645-4DDF', 3),
('2345-BCDE-6645-5DDF', 4),
('2345-BCDE-6645-6DDF', 5),
('2345-BCDE-6645-7DDF', 6),
('2345-BCDE-6645-aDDF', 7),
('2345-BCDE-6645-sDDF', 8),

('2345-BCDE-6645-dDDF', 11),
('2345-BCDE-6645-dDDF', 12);
WITH cte AS (
SELECT
IN_ID,
IN_InvoiceID,
CASE
WHEN (((ROW_NUMBER() OVER (ORDER BY IN_InvoiceID) - 1) / 5) % 2 = 0) THEN 'L'
ELSE 'R'
END AS IN_Position
FROM #InvoiceTable
),
cteL AS (
SELECT IN_ID, IN_InvoiceID, ROW_NUMBER() OVER (ORDER BY IN_InvoiceID) AS IN_RowNumber
FROM cte
WHERE IN_Position = 'L'
),
cteR AS (
SELECT IN_ID, IN_InvoiceID, ROW_NUMBER() OVER (ORDER BY IN_InvoiceID) AS IN_RowNumber
FROM cte
WHERE IN_Position = 'R'
)
SELECT cteL.IN_ID, cteL.IN_InvoiceID, cteR.IN_ID, cteR.IN_InvoiceID
FROM cteL
LEFT JOIN cteR ON (cteL.IN_RowNumber = cteR.IN_RowNumber)

Suppose I have a list of values, such as 1, 2, 3, 4, 5 and a table where some of those values exist in some column. Here is an example:
id name
1 Alice
3 Cindy
5 Elmore
6 Felix
I want to create a SELECT statement that will include all of the values from my list as well as the information from those rows that match the values, i.e., perform a LEFT OUTER JOIN between my list and the table, so the result would be like follows:
id name
1 Alice
2 (null)
3 Cindy
4 (null)
5 Elmore
How do I do that without creating a temp table or using multiple UNION operators?
If in Microsoft SQL Server 2008 or later, then you can use Table Value Constructor
Select v.valueId, m.name
From (values (1), (2), (3), (4), (5)) v(valueId)
left Join otherTable m
on m.id = v.valueId
Postgres also has this construction VALUES Lists:
SELECT * FROM (VALUES (1, 'one'), (2, 'two'), (3, 'three')) AS t (num,letter)
Also note the possible Common Table Expression syntax which can be handy to make joins:
WITH my_values(num, str) AS (
VALUES (1, 'one'), (2, 'two'), (3, 'three')
)
SELECT num, txt FROM my_values
With Oracle it's possible, though heavier From ASK TOM:
with id_list as (
select 10 id from dual union all
select 20 id from dual union all
select 25 id from dual union all
select 70 id from dual union all
select 90 id from dual
)
select * from id_list;
the following solution for oracle is adopted from this source. the basic idea is to exploit oracle's hierarchical queries. you have to specify a maximum length of the list (100 in the sample query below).
select d.lstid
, t.name
from (
select substr(
csv
, instr(csv,',',1,lev) + 1
, instr(csv,',',1,lev+1 )-instr(csv,',',1,lev)-1
) lstid
from (select ','||'1,2,3,4,5'||',' csv from dual)
, (select level lev from dual connect by level <= 100)
where lev <= length(csv)-length(replace(csv,','))-1
) d
left join test t on ( d.lstid = t.id )
;
check out this sql fiddle to see it work.
Bit late on this, but for Oracle you could do something like this to get a table of values:
SELECT rownum + 5 /*start*/ - 1 as myval
FROM dual
CONNECT BY LEVEL <= 100 /*end*/ - 5 /*start*/ + 1
... And then join that to your table:
SELECT *
FROM
(SELECT rownum + 1 /*start*/ - 1 myval
FROM dual
CONNECT BY LEVEL <= 5 /*end*/ - 1 /*start*/ + 1) mypseudotable
left outer join myothertable
on mypseudotable.myval = myothertable.correspondingval
Assuming myTable is the name of your table, following code should work.
;with x as
(
select top (select max(id) from [myTable]) number from [master]..spt_values
),
y as
(select row_number() over (order by x.number) as id
from x)
select y.id, t.name
from y left join myTable as t
on y.id = t.id;
Caution: This is SQL Server implementation.

can anybody help me?
If you can do it, I'd advise you to renumber the values so that the 'logical' order sticks to the alphabetical order. F-1 will then be updated to F-01, or F-001.
If you cannot do it, add a field that will be populated with the 'ordered' form of your code. You 'll then be able to order by the F-001 column and still display the F-1 value
Otherwise ordering your records will rapidly become your nightmare.
Using Patindex to find the first numeric expression as first sort field, then extracting the numeric part as integer as second sortfield and using the whole string as third sort field you might get the desired result.
