Inserting values in atable based on values in another table

Question

Hi,
We receive data from our customers as follows AB784589456. This is the starting value for an serial number of a product. We also receive a quantity. I need to be able to populate rows in another table to start with AB784589456 and then add an additional
row to the value of the quantity. So the first row in the second table would be AB784589456, the second AB784589457, AB784589458, etc until the number has been incremented to the value of the quantity.
Order Number     SerialNo
234                     AB784589456
234                     AB784589457
234                     AB784589458
The datatype of the SerialNo is Varchar(14)
Any help would be appreciated
Thanks

Assuming the serial value format is consistent ie alphabet followed by numeric you can use this
DECLARE @Serial varchar(14) = 'AB784589456', @Quantity int = 15
;With N1
AS
SELECT 1 N UNION ALL SELECT 1 UNION ALL SELECT 1
),N2
AS
SELECT 1 N FROM N1 t1 CROSS JOIN N1 t2
),N3
AS
SELECT 1 N FROM N2 t1 CROSS JOIN N2 t2 CROSS JOIN N2 t3
),N4
AS
(SELECT ROW_NUMBER() OVER (ORDER BY (SELECT 1)) AS Seq
FROM N3
INSERT INTO YourTable (OrderNumber,SerialNo)
SELECT OrderNumber,LEFT(@Serial,PATINDEX('%[0-9]%',@Serial)-1) + CAST(STUFF(@Serial,1,PATINDEX('%[0-9]%',@Serial)-1,'') + Seq -1 AS varchar(11))
FROM Table1 t
CROSS JOIN N4 n
WHERE n.Seq BETWEEN 1 AND @Quantity
