sql server (alternate): Hi Friends,

How can we insert records in sorted order

like consider a table

No Name Phone
1 test1 12345
1 test1 23455
2 test2 68638
3 test3 67684
4 test4 54808
4 test4 74594


if i add a new record like this

2 test2 34454

it should go in specific order. so that the final table should look
something like this

No Name Phone
1 test1 12345
1 test1 23455
2 test2 34454
2 test2 68638
3 test3 67684
4 test4 54808
4 test4 74594

Tables don't store data in a logical order. They store data in a
physical order. If you want to see data in an ordered fashion then
create a view to do that. Also, Name is a reserved word, don't use
it...

SELECT
No,
NameField,
Phone
FROM
yourTable
ORDER BY
No, NameField, Phone

But actually i want to do further processing with that sorted table.
Thats why i am in need of such structure

Thanks

What exactly do you want to do? Maybe there is a better way of doing
it that you haven't come across.

Give a little more detail and more help can be given.

More specifically, it sounds like he (like many others) is stuck on
procedural rather than functional thinking. Beware the frumious CURSOR!

Actually i will combine the multiple numbers into one single record

the temporary table structure would be like this

No Name Phone FinalPhone
1 test1 12345 12345
1 test1 23455 12345<br> 23455
2 test2 68638 68638
2 test2 34454 68638<br> 34454<br>
2 test2 45445 68638<br> 34454<br> 45445
3 test3 67684 67684
4 test4 54808 54808
4 test4 74594 54808<br> 74594


and by using GROUP BY clause i would select single record having all
the
information


No Name FinalPhone
1 test1 12345<br> 23455
2 test2 68638<br> 34454<br> 45445
3 test3 67684
4 test4 54808<br> 74594

this view would be sent to UI for display...

Thanks

Add a DateInserted column, and use it in sorting.

If you delete the row with Phone = 34454, do you want to have to also
update the row with 45445 so that FinalPhone = 68638<br>45445? Of
course not - that would be a maintenance nightmare. Move FinalPhone

I created two tables and a trigger and I have all the functionality
that you wanted, without having to create a cursor. The key is to let
the database do the work and this way, any record that validly gets
inserted into the phone_numbers table automatically gets put into the
phone_output list.

If you expect to be deleting or modifying records from the
phone_numbers table then you will need to add update and delete
triggers. (Note: for delete, use the replace function)

If you need more help, just post back.

Try this:

-- Begin SQL
CREATE TABLE [dbo].[phone_numbers](
[num] [int] NOT NULL,
[phone_name] [varchar](50) NOT NULL,
[phone] [varchar](50) NOT NULL
) ON [PRIMARY]
GO

CREATE UNIQUE NONCLUSTERED INDEX [nat_key] ON [dbo].[phone_numbers]
(
[num] ASC,
[phone] ASC
) ON [PRIMARY]
GO

CREATE TABLE [dbo].[phone_output](
[num] [int] NOT NULL,
[phone_name] [nvarchar](50) NOT NULL,
[final_phone] [varchar](max) NULL
) ON [PRIMARY]
GO

CREATE TRIGGER [dbo].[update_final_phone]
ON dbo.phone_numbers
AFTER INSERT
AS
BEGIN
insert into
phone_output(num, phone_name)
select distinct
i.num,
i.phone_name
from

left outer join phone_output p
on i.num = p.num
where
p.num is null

update
phone_output
set
final_phone = coalesce(final_phone + '<br>','') + phone
from

where
phone_output.num = i.num
END
GO

insert into phone_numbers (num,phone_name,phone) values

select * from phone_numbers
select * from phone_output
-- End SQL

GROUP BY is not your guy, in this case. See this link for some ideas on
to produce concatenated lists:
