I have a table with 170,597 rows in it.
I need to Select the first 60,000 then the second 60,000, etc..
But I have no Identity column I can use for a count.
How else can I do this?  thanks   SQL Server 2005

SELECT Customer.Email, Customer.LName ......
FROM  Customer
where ???
order by Customer.LName

One possibility is using EXCEPT

declare @endrow int
declare @startrow int
set @endrow = 120000
set @startrow = 60001

select * from (select top(@endrow) * from Customer order by LName) t1
except
select * from (select top@(startrow) * from Customer order by LName) t2

no problem:

select * from (
SELECT rowno = (row_number() over(order by Customer.Email)%60000) + 1, Customer.Email, Customer.LName ......
FROM  Customer
)
where rowno = 1

Use row_number like chapmandew's, but don't use %, use / in the same place. Rowno 1 gives first 60k, 2 is next etc

yep, thats why I did it.  could partition it into "pages" so you don't have to go through and do the math each time for it.

1 = first 60K pages
2 = 60001 - 120000

I added :
where Customer.CustomerID between 1088 and 61088

Actually the above line should not have been there when I first posted
and tried the query, . . I was just trying something else at the time . .

They already told you
where rowno = 2 will get second batch
If you are still interested you can also take a look at my approach and compare the speed.

Hi all,

Just quick correction.. again :)
Added a -1 so that the first batch returns 60000, not 59999
select * from (
SELECT rowno = (row_number() over(order by Customer.LName)-1)/60000 + 1, Customer.Email, Customer.LName as 'LastName', Customer.FName as 'First Name',
Customer.Address1 as 'Address', Customer.City,
Customer.Region, Customer.PostalCode, Customer.Country, Product.Name as 'Product Name', Orders.OrderID
FROM Customer INNER JOIN
Orders ON Customer.CustomerID = Orders.CustomerID INNER JOIN
OrderDetail ON Orders.OrderID = OrderDetail.OrderID INNER JOIN
Product ON OrderDetail.ProductID = Product.ProductId
--where CustomerID between 1088 and 61088

) a
where rowno = 1
order by a.LastName
