return duplicate records

Hello experts,

I'm trying the run the following query with specific intentions.

I would like the query to return 5 results; i.e., 4 distinct and one
duplicate. I am only getting, however, 4 distinct records. I would
like the results from the '007' id to spit out twice.

I'm not using 'distinct,' and I've tried 'all.' I realize that I
could put my 5 employee id's in a table and do a left or right join; I
would like to avoid that, however. Any thoughts?

Select
Employee_last_name,
Employee_first_name

alexAlex,

There are a few solutions. Two are (might have typos, but you should be
able to get the idea):

select Employee_last_name, Employee_first_name
from tbl_employee
join (
select '009' as id union all
select '008' as id union all
select '007' as id union all
select '007' as id union all
select '006' as id
) as IDs
on IDs.id = tbl_employee.employee_id

or to make the specification of ids simpler:

declare @.ids varchar(1000)
set @.ids = '009008007007006'
declare @.idlength int
set @.idlength = 3

select Employee_last_name, Employee_first_name
from tbl_employee
join a_permanent_table_of_integers_from_0_to_whatever as Nums
on employee_id = substring(@.ids,@.idlength*n+1,@.idlength)
and n < len(@.ids)/@.idlength
-- [n] is the column name for the permanent table and should
-- be that tables primary key

The easy way is a UNION, based on a guess about the DDL you did bother
to post and the uniquness of emp_id:

SELECT last_name, first_name
FROM Personnel
WHERE emp_id IN ('009', '008', '007', '006')
UNION
SELECT last_name, first_name
FROM Personnel
WHERE emp_id = '007'|||--CELKO-- (jcelko212@.earthlink.net) writes:

Joe, I thought you knew SQL? This query will not return the results
that Alex was asking for.

Why is left as an exercise to the reader.

retrieving specific page(number of rows) form table

hi,

i need SP that receive 2 integers ,@.NUM_ROWS and @.PAGE_NUMBER,
and return the rows in that page.
for example:

SP(4,2) will return 4 rows in page number 2 .

So if i have table with 9 rows i will get rows 5-8,
the first page is rows 1-4 the second page is 5-8 and the 3 page is row 9.

i have to assume that rows can be deleted form that table.
thanksYou have to have a (preferably unique) column or set of columns to order the data consistently each call. Do you have an incrementing identity field or datetime stamp?|||i have the PK of the table, but i have to assume some records have been deleted.
so i can not assume i have perfectly order column|||Not necessary.
declare @.NUM_ROWS int
declare @.PAGE_NUMBER int

select [YourTable].*
from [YourTable]
inner join --PageRows
(select [PKey],
count(*) as RowNum
from [YourTable]
inner join [YourTable] Ordinal on [YourTable].[PKey] >= Ordinal.[PKey]
having count(*) between (@.PAGE_NUMBER * @.NUM_ROWS) + 1 and (@.PAGE_NUMBER + 1) * @.NUM_ROWS) PageRows
on [YourTable].[Pkey] = PageRows.Pkey
