extracting the specified record no of records from database table

hi all,

I need to select the no of records on the basis of specified range of records.

In oracle i found rownum, i could not find it in sqlserver. how the data are extracted from the huge records..

I have used temporary table,map the table primary key to the next table with identity

but i dont find it good. I need to ignore the insert the data in next table or craeting new table having the rowid ...

Is there some other best way to extract the specified data

here is the type of query.

select * from customers where rownum between 1000 and 10000

this is in oracle

i am in need to do this in the sql server

waiting for the response...............................

There is no such thing like row number in MS SQL. You will need to create an identity column in your table, or maintain the number column manually.|||

If you are using SQL Server 2005 then you can use the ROW_NUMBER() function instead:

select *

from (select *, row_number() over(order by CustomerId) as rownum

from customers

) as c

where c.rownum between 1000 and 10000;

If you are using SQL Server 2000 then the identity column approach using temporary table is the best way to go (I guess you are doing this now based on the information in your post).

Also, it seems like you are trying to batch some DML operation. If so you can use SET ROWCOUNT or TOP clause in DML (SQL Server 2005). See below for example:

declare @.n int

set @.n = 1000 -- set number of rows you want to insert at a time

set rowcount @.n

while(1=1)

begin

insert into MasterCustomers

select ...

from Customers as c1

where not exists(

select * from MasterCustomers as c2

where c2.CustomerName = c1.CustomerName)

if @.@.rowcount = 0 break

end

set rowcount 0

-- using TOP

declare @.n int

set @.n = 1000 -- set number of rows you want to insert at a time

while(1=1)

begin

insert top(@.n) into MasterCustomers

select ...

from Customers as c1

where not exists(

select * from MasterCustomers as c2

where c2.CustomerName = c1.CustomerName)

if @.@.rowcount = 0 break

end

|||SQL 2000 does not have the limit keyord. You can use double TOP instead of, but you must have a primary key on that table
select * from
(select top 1000 * from (
select top 11000 *
from customers
order by customer_id asc
) as tmp1
order by cutomer_id desc
) as tmp2
order by ...

for extract customers betweeen 10000 and 11000 based on customer_id

if you use sql2005

you also can use the function ROW_NUMBER() to

select rownum between 1000 and 10000 like oracle

example:

with customers _temp as

(SELECT ROW_NUMBER() OVER (order by customer) as RowNumber,*
from customers)
select *
from customers _temp
where RowNumber between 1000 and 10000
