Just a day ago, I received interesting question on this blog. Read original question here. This is very good question and after reading this question I quickly wrote small script as answer. Let us see the question and answer together.
Q. How can we generate incremented linear number in sql server as in oracle we generate in via sequence?
A. Run following script which will generate output in sequence, which will generate output as you requested.
DECLARE @idt INT SET @idt = 0 WHILE (@idt < 100) BEGIN SELECT @idt = @idt + 1 PRINT @idt END

Can anyone please help me on generating a range from the following data.
I have a table that contains following values
I want them as:
Thanks in advance.
In MS Sql i need a SP to generate a sequence number starting from 1 till the End of the day 23:59:59 and when the clock starts 24:00:00(next day) it should again start with 1 and repeat.
You can also check this article that discusses how to generate unique numbers at:

one of these work in a recursive CTE Query. I desperately need to sequentially number a recursive query. Any reasonably fast method will do.
i want to change a column value in sql table after date has been changed.
ID Date DueDays

any suggestions ?
I was doing exactly this today and I thought of another great way to do this using the simplest possible recursive CTE.
;WITH Num_Cons AS
SELECT 1 AS Num
SELECT Num + 1 AS Num
WHERE Num < 100
SELECT * FROM Num_Cons
option (MAXRECURSION 0)
One advantage of this is that you will not need to use a loop which can become costly when your dataset becomes large, I processed 1 million consecutive numbers this way in 8 seconds versus 18 seconds the loop way.
Another advantage is that you have all the results in a tabular format which saves having to create a table and insert them.
I want to create a procedure which would create a serial number using a stored procedure.
I have three tables:
create table ItemTypes
ItemTypeID int not null primary key,
create table ItemBatchNumber
ItemBatchNumberID int not null primary key,
create table ItemMfg
ManufactureID int not null primary key,
ItemBatchNumberID int foreign key references ItemBatchNumber(ItemBatchNumberID),
For each Item Type there are several Item batch number.
Now, first 3 digit of serial no is xyz. 4 digit of serial no should be Item Type(e.g if Item type is ‘b’ then serial no should be xyzb).
5 digit of serial no should be like this:
In a day, for first Item batch number of a Item type, 5th digit should be 1 and it will remain 1 for that day.For the next different Item batch number it should be 2 and it will remain 2 for that day.
Same rule applied for next day and other item type.
e.g suppose ‘b’ Item Type has 3 Item batch number WB101,WB110,WB231. If today someone select WB110(Item batch number) of ‘b’ Item Type first then Serial No should be xyzb1 and it will remain xyzb1 for today for WB110. Now if someone select WR101 next then Serial No should be xyzb2 for today. Tomorrow which Item batch number of ‘b’ Item type will be selected first, for that batch number and that type serial no should be xyzb1. Same rule applied for other item type.
I have tried till now:
Create Procedure SerialNumber
‘serial No is: xyz’+” + @ItemType + ” +
(Select cast(Row_Number() over (order by ItemBatchNumber) as varchar(5))
where ItemBatchNumber = @ItemBatchNumber
and ItemType = @ItemType
ItemTypes.ItemType = @ItemType
I am new to SQL. 4rth digit of SN is generated correctly from my code.Please give me some idea on generating 5th digit and let me know if you have any doubt. Thanks in advance.
