I want to create a procedure in which the following details should be displayed:-
I have created this query but I am not getting the right results. I have attached the table schema.
TABLES WE ARE USING:- InvoiceData, CustomerDetails and InvoiceItems
Table Schema ->
1. InvoiceItems TABLE1
2. CustomerDetails Table2
3. InvoiceDetails enter image description here
There are 2 sections for invoice:-
In the first section of the Invoice, Below details should be displayed.
Invoice Information section
In the second section of the invoice, the below details should be displayed:-
Invoice Items description section
I am attaching the query below:-
alter Procedure SaveInvoiceDetails
(
#CustomerId varchar(50),
#InvoiceNumber varchar(50),
#InvoiceDate date,
#InvoiceMonth int,
#FromDate date,
#ToDate date,
#Rate int,
#Quantity int,

#ZoneId int
)
as
set nocount on;
begin
Declare #TotalRows int
Declare #NumPages int
set #TotalRows = 0
Select ROW_NUMBER() over (order by C.CustomerId) as InvoiceRow,
C.CustomerId, I.InvoiceNumber, I.InvoiceDate, I.FromDate, I.ToDate,

End
End
SELECT * FROM #tempInvoice ORDER BY InvoiceRow asc
return
So I am expecting that you got all the records in your #tempInvoice from your procedure. And face problem in only generating invoice number with the format you provided.
For each region you already have a specific code generated at your end ( I am guessing).
#regioncode ---- this table contain record of zoneid and zoneocde for each area
If you don't have any table for region then prepare one before going forward as this needs you everywhere in your code section.
At the end pf your procedure need to update this to return your required result.
; with cte as (
select row_number() over (partition by ZoneId order by InvoiceDate) as Slno, * from #tempInvoice as t inner join #regioncode as r on t.zoneid=r.zoneid
)
select zonecode + '_' + cast(slno as varchar(10)) as Uniquecode, * from cte

I have a customers table and an orders table. I want to display the customer and all of his/her order dates on one row, rather than multiple rows. Here is what I have and what I'm looking for:
Basic code to get results:
select customerid, name, orderdate
from customer_table c inner join
order_table o
on c.customerid = o.customerid
this will work at the most you cant show it on different columns having nulls:
select customer_id,name,LISTAGG(orderdate, ', ') WITHIN GROUP (ORDER BY orderdate)
from(select customerid, name, orderdate
from customer_table c inner join
order_table o
on c.customerid = o.customerid );
You can use the following because you're bound by the 12 order limit. If you expand to an unknown number of orders with no upper limit, then you would need to use dynamic SQL and even then it would be tricky, because you would also need to dynamically create unique column names.
This query batches by customer and sets the order values. They will be in dated order and set as NULL if there's no more orders. It kinda assumes that at least one customer has 12 orders. You'll get a column of all NULLS if that's not the case
IF OBJECT_ID('tempdb..#Results') IS NOT NULL DROP TABLE #Results
IF OBJECT_ID('tempdb..#sortedRows') IS NOT NULL DROP TABLE #SortedRows
DECLARE #CustomerList TABLE(CustomerID INT, RowNo INT);
INSERT INTO #CustomerList SELECT DISTINCT CustomerID, ROW_NUMBER() OVER(ORDER BY CustomerID) RowNo FROM Customer_Table (NOLOCK)

Try this if you use MS SQL Server:
-- 1st, get the number of columns
declare #columnnumber int = 1
select #columnnumber = max(a.count)
from (
select c.cid,c.name, count(o.orderdate) as count
from
customer_table c
join order_table o
on c.cid = o.cid
group by c.cid,c.name)a
print #columnnumber
-- Compose the column names for Pivot
declare #columnname varchar(max) = ''
declare #int int = 1
while #int <= #columnnumber
begin
set #columnname = #columnname + '[date' + cast(#int as varchar(10))+ '],'
set #int = #int + 1
end
set #columnname = '('+left(#columnname,len(#columnname)-1)+')'
print #columnname
--Pivot !!! + Dynamic SQL
declare #str varchar(max)
set #str =
'SELECT *
FROM
(SELECT c.cid,c.name, o.orderdate,concat(''date'',row_number() over (partition by c.cid,c.name order by o.orderdate)) rnk
FROM customer_table c
join order_table o
on c.cid = o.cid) AS s
PIVOT
(
min(s.orderdate)

print #str
execute (#str)
Please change the column name. I used cid as your customerid.
Output:

Like others said, it's in principle impossible (in pure SQL) to generate this not knowing how many orders you have for a single customer.
I like #nikhil-sugandh's answer, it works great if you are OK with having all orders comma-separated in a single column.
If you insist on having multiple columns, you can build on that answer, by replacing LISTAGG with ARRAY_AGG and postprocessing it. It will be MUCH more efficient than e.g. the proposed solution with multiple joins. You can also use ARRAY_SLICE to handle cases when there are more orders than you are prepared for.
Example (note, I added an extra order to demonstrate handling more-than-expected orders
create or replace table customer_table(customerId int, name varchar)
as select * from values
(12,'John'),(4,'Nancy');
create or replace table order_table(orderId int, customerId int, orderDate date)
as select * from values
(1,12,'3/4/2017'),(2,12,'5/26/2017'),(3,12,'12/1/2017'),(4,4,'2/1/2017'),(5,12,'1/1/2019');
with subq as (
select c.customerid, name,
array_agg(orderdate) within group (order by orderdate) as orders
from customer_table c
inner join order_table o on c.customerid = o.customerid
group by c.customerid, c.name
)
select customerid, name,
orders[0]::date AS order1, orders[1]::date AS order2,
array_to_string(array_slice(orders, 2, 999), ' , ') AS overflow
from subq;
------------+-------+------------+------------+-------------------------+
CUSTOMERID | NAME | ORDER1 | ORDER2 | OVERFLOW |
------------+-------+------------+------------+-------------------------+
4 | Nancy | 2017-02-01 | [NULL] | |
12 | John | 2017-03-04 | 2017-05-26 | 2017-12-01 , 2019-01-01 |
------------+-------+------------+------------+-------------------------+
first create a view like this:
create view order_view as
select
count(*) over (partition by customerId order by orderDate) as ord,
CustomerId,
orderdate
from order_table
then you can use this query:
select c.customerid,
o1.orderdate,
o2.orderdate
o3.orderdate
.
.
.
o12.orderdate
from customer_table c
left join order_view o1
on c.customerid = o1.customerid and ord = 1
left join order_view o2
on c.customerid = o2.customerid and ord = 2
left join order_view o3
on c.customerid = o3.customerid and ord = 3
.
.
.
left join order_view o12
on c.customerid = o12.customerid and ord = 12

You're only fetching from the cursor once and your while loop is checking the status of that fetch. Since it presumably succeeded, that condition is always evaluated as true.
For what it's worth, here's the template that I use for my cursors:
declare cursorName cursor fast_forward local for
-- your select goes here
OPEN cursorName
WHILE (1=1)
BEGIN
FETCH NEXT FROM cursorName INTO --variable list here
if (##FETCH_STATUS <> 0)
BREAK;
-- do stuff here
END
CLOSE cursorName
DEALLOCATE cursorName
Good day all,
I have the following cursor query and would like to replace it with a set based query to address performance issues.
DECLARE #EmpIDM CHAR(21);
DECLARE #EmpName CHAR(21);
DECLARE #EMPCatID INT;
DECLARE Assign_Emp SCROLL CURSOR
FOR
SELECT DISTINCT EMP
, EMPNAME
FROM HR_EMPLOYEES
SET NOCOUNT ON
OPEN Assign_Emp;
FETCH NEXT
FROM Assign_Emp
INTO #EmpIDM
, #EmpName
WHILE ##FETCH_STATUS = 0
BEGIN
SET #EMPCatID = (
SELECT TOP 1 CategoryID
FROM Categories
)
UPDATE Categories
SET CategoryID = (CategoryID + 1) /*Increment Category ID for next Insert*/
INSERT INTO Table1 (
EmpNumber
, EmployeeName
, EmployeeCategoryID
)
VALUES (
#EmpIDM
, #EmpName
, #EMPCatID
)
FETCH NEXT
FROM Assign_Emp
INTO #EmpIDM
, #EmpName
END
CLOSE Assign_Emp;
CLOSE Assign_Emp;
SET NOCOUNT OFF
My challenge is adapting the following code segment into a set based operation
SET #EMPCatID = (
SELECT TOP 1 CategoryID
FROM Categories
)
UPDATE Categories
SET CategoryID = (CategoryID + 1) /*Increment Category ID for next Insert*/
I humbly appreciate any insight on how I can achieve this.
Many Thanks,
Re-write using temp. table with identity column:
declare #offset int
select #offset = isnull(max(CategoryID),0) from Categories
create table #data (
EmpNumber CHAR(21),
EmployeeName CHAR(21),
EmployeeCategoryID int identity
)
INSERT INTO #data (
EmpNumber
, EmployeeName)
SELECT DISTINCT EmpIDM
, EmpName
FROM HR_EMPLOYEES
insert into Table1 (
EmpNumber

EmpNumber
, EmployeeName
, EmployeeCategoryID + #offset
from #data
update Categories
set CategoryID = (select max(EmployeeCategoryID) from #data) + #offset
I working on FIFO implementation in sql.
I have Batch number concept in my application.
If suppose I am selling on inventory then my application should tell me that which inventory is the first come.
Lets. Say I purchased Inventory 'A' on 4th-Aug, 5th-Aug & 6th-Aug
On 4th Aug - A Inventory has batch number BT002 - 10 (Qty)
On 5th Aug - A's Inventory has batch number BT003 - 15 (Qty)
On 6th Aug - A's Inventory has batch number BT001 - 10 (Qty)
So, Now I am having stock Now in my hand as following :
A Inventory
BT002 - 10 - 4-Aug
BT003 - 15 - 5-Aug
BT001 - 10 - 6-Aug
Now If I want to sell that Inventory to anybody then my application should tell me that I should sell
BT002 (Batch number) inventory first beacause it came first.
That was the concept I am using in my application.
Now I want to sell 15 Qty from 'A' (Inventory).
Then O/p Should be like this :
BT002 - 10
BT003 - 5
Here's My Query :
SELECT ISNULL(SUM(qty),0) AS Qty,batch_no,accept_date FROM RS_GIN_Master
GROUP BY batch_no,accept_date
HAVING ISNULL(SUM(qty),0) <= 15
ORDER BY accept_date asc
O/p Of Given Query :
How can I get O/P like this :
BT002 - 10
BT003 - 5
Any Help will be appreciated.
Thank you in Advance.
This should work for you:

Just make sure to replace the marked part of the function with your query...
You need to create a stored procedure in your database and taking the quantity from your stock table. And you should also have the id of each record to update that records from where u have taken that qty.
Alter PROCEDURE sp_UpdateStockForSale
#batchNO varchar(10),
#qty decimal(9,3)
AS
BEGIN
Create Table #tmpOutput(ID int identity(1,1), StockID int, batchNo varchar(10), qty decimal(9,3));
SET NOCOUNT ON;
DECLARE #ID int;
DECLARE #Stock Decimal(9,3);
DECLARE #TEMPID int;
Select #TEMPID=(Max(ID)+1) From RS_GIN_Master Where qty > 0 And batch_no = #batchNO;
While (#qty > 0) BEGIN
Select #ID=ID, #Stock=qty From RS_GIN_Master Where qty > 0 And batch_no = #batchNO AND ID < #TEMPID Order By accept_date Desc;
--If Outward Qty is more than Stock
IF (#Stock < #qty) BEGIN
SET #qty = #qty - #Stock;
SET #Stock = 0;
END
--If Outward Qty is less than Stock
ELSE BEGIN
SET #Stock = #Stock - #qty;
SET #qty = 0;
END
Insert Into #tmpOutput(StockID,batchNo,qty)Values(#ID,#batchNO,#Stock);
SET #TEMPID = #ID;
--This will update that record don't need it now.
--Update RS_GIN_Master Set qty = #Stock Where ID=#ID
END
Select StockID, batchNo, qty From #tmpOutput;
END
GO
The above example is not compiled but, you can get the logic how you can retrieve the records from your stock table according to FIFO method. You can use accept_date instead of ID in RS_GIN_Master table. but, i would prefer to make it unique so, if i want to get a specific record then it can be possible.
One query .. like this
This should be tweaked for you case as you have groups and other stuff, is only for example purposes.
;with qty as (
select 15 as value
)
,l as (
select
ROW_NUMBER () over (order by accept_date desc) rn
,*
from xxx
)
,q as (
select
batch_no
,accept_date
,case when value>qty then value-qty else 0 end as remainder
,case when value>qty then qty else value end as used
,rn
from l
cross join qty
where rn=1
union all
select
r.batch_no
,r.accept_date
,case when q.remainder>r.qty then q.remainder-r.qty else 0 end as remainder
,case when q.remainder>r.qty then r.qty else q.remainder end as used
,r.rn
from q
join l r
on q.rn+1 = r.rn
where q.remainder!=0
)
select *
from q
where used != 0
and the fiffle for it http://sqlfiddle.com/#!6/9b063/34/0
Below should work for you
Create table RS_GIN_Master
(id int,
qty int,
batch_no varchar(5),
accept_date Datetime
)
GO
Insert into RS_GIN_Master (id, qty, batch_no, accept_date)
values(1,10,'BT001','2018-04-06')
Insert into RS_GIN_Master (id, qty, batch_no, accept_date)
values(2,10,'BT002','2018-04-04')
Insert into RS_GIN_Master (id, qty, batch_no, accept_date)
values(3,15,'BT003','2018-05-06')
GO
----------------------------
CREATE PROC FIFO
#TakenQty int
AS
BEGIN
WITH cte AS (SELECT *, SUM(qty) OVER (ORDER BY accept_date, id ASC) as CumQty FROM RS_GIN_Master WHERE qty>0)
SELECT TOP ((SELECT COUNT(*) FROM cte WHERE CumQty <#TakenQty)+1) batch_no, accept_date,
CASE
WHEN CumQty<#TakenQty THEN qty
ELSE #TakenQty -(CumQty-Qty)
END AS TakenOut
FROM cte
END
Result
| batch_no | accept_date | TakenOut |

I am completely new to stored procedure. This time, I need to create a stored procedure in MS SQL.
Let's say I have the following table.
Table name: ListOfProducts
--------------------------
SomeID, ProductID
34, 4
35, 8
35, 11
How do I pass in a SomeID. Use this SomeID to select a recordset from table, ListOfProducts. Then loop through this record set.
Let's say I pass in SomeID = 35.
So, the record set will return 2 records with SomeID 35. In the loop, I will get ProductID 8 and 11, which will be used to do another select from another table.
The stored procedure should return the results from the 2nd select.
How can I do this in MS SQL stored procedure?
Sorry, for this newbie question. Thanks for any help.
If you want looping through the records. You can do like:
--Container to Insert Id which are to be iterated
Declare #temp1 Table
(
tempId int
)
--Container to Insert records in the inner select for final output
Declare #FinalTable Table
(
Id int,
ProductId int
)
Insert into #temp1
Select Distinct SomeId From YourTable
-- Keep track of #temp1 record processing
Declare #Id int
While((Select Count(*) From #temp1)>0)
Begin
Set #Id=(Select Top 1 tempId From #temp1)
Insert Into #FinalTable
Select SomeId,ProductId From ListOfProducts Where Id=#Id
Delete #temp1 Where tempId=#Id
End

There is probably no point in writing an explicit loop if you don't need to preform some action on the products that can't be done on the whole set. SQL Server can handle stuff like this much better on its own. I don't know what your tables look like, but you should try something that looks more like this.
CREATE PROC dbo.yourProcName
#SomeID int
AS
BEGIN
SELECT
P.ProductId,
P.ProductName
FROM
Product P
JOIN
ListOfProducts LOP
ON LOP.ProductId = P.ProductId
WHERE
LOP.SomeId = #SomeID
END
I had to do something similar in order to extract hours from a select resultset start/end times and then create a new table iterating each hour.
DECLARE #tCalendar TABLE
(
RequestedFor VARCHAR(50),
MeetingType VARCHAR(50),
RoomName VARCHAR(MAX),
StartTime DATETIME,
EndTime DATETIME
)
INSERT INTO #tCalendar(RequestedFor,MeetingType,RoomName,StartTime,EndTime)
SELECT req as requestedfor
,meet as meetingtype
,room as rooms
,start as starttime
,end as endtime
--,u.datetime2 as endtime
FROM mytable
DECLARE #tCalendarHours TABLE
(
RequestedFor VARCHAR(50),
MeetingType VARCHAR(50),
RoomName VARCHAR(50),
Hour INT
)
DECLARE #StartHour INT,#EndHour INT, #StartTime DATETIME, #EndTime DATETIME
WHILE ((SELECT COUNT(*) FROM #tCalendar) > 0)
BEGIN
SET #StartTime = (SELECT TOP 1 StartTime FROM #tCalendar)
SET #EndTime = (SELECT TOP 1 EndTime FROM #tCalendar)
SET #StartHour = (SELECT TOP 1 DATEPART(HOUR,DATEADD(HOUR,0,StartTime)) FROM #tCalendar)
SET #EndHour = (SELECT TOP 1 DATEPART(HOUR,DATEADD(HOUR,0,EndTime)) FROM #tCalendar)
WHILE #StartHour <= #EndHour
BEGIN
INSERT INTO #tCalendarHours
SELECT RequestedFor,MeetingType,RoomName,#StartHour FROM #tCalendar WHERE StartTime = #StartTime AND EndTime = #EndTime
SET #StartHour = #StartHour + 1
END
DELETE #tCalendar WHERE StartTime = #StartTime AND EndTime = #EndTime
END
Do something like this:
Declare #ID int
SET #ID = 35
SELECT
p.SomeID
,p.ProductID
FROM ListOfProducts p
WHERE p.SomeID = #ID
-----------------------
--Or if you have to join to get it
Declare #ID int
SET #ID = 35
SELECT
c.SomeID
,p.ProductID
,p.ProductName
FROM ListOfProducts p
INNER JOIN categories c on p.ProductID = c.SomeID
WHERE p.SomeID = #ID
You can use option with WHILE loop and BREAK/CONTINUE keywords
CREATE PROC dbo.yourProcName
#SomeID int
AS
BEGIN
IF OBJECT_ID('tempdb.dbo.#resultTable') IS NOT NULL DROP TABLE dbo.#resultTable
CREATE TABLE dbo.#resultTable
(Col1 int, Col2 int)
DECLARE #ProductID int = 0
WHILE(1=1)
BEGIN
SELECT #ProductID = MIN(ProductID)
FROM ListOfProducts
WHERE SomeID = #SomeID AND ProductID > #ProductID
IF #ProductID IS NULL
BREAK
ELSE
INSERT dbo.#resultTable
SELECT Col1, Col2
FROM dbo.yourSearchTable
WHERE ProductID = #ProductID
CONTINUE
END
SELECT *
FROM dbo.#resultTable
END
