If all the id’s are integers, then you could possible use the Convert or Cast.
http://blog.sqlauthority.com/2007/07/07/sql-server-convert-text-to-numbers-integer-cast-and-convert/

But yes, that is why order id column is not sequentially ordered. So if the id has a space before or after number, the order is treated differently as a true integer datatype.

Hi Carl thank you so much 4 your help, actually i’m a jr programer so i’m working in a database who other guys did and they decided to set varchar the type of the product id.

i guess this is why it orders 1,10,100 not sequentially, but exist one way to order the ids in sequentially way? or because they’re numbers and are set like char it cannot do??

thnks alot!

Why are you using a varchar for ID field?

By: Tomoyo

Tomoyo — Mon, 24 Oct 2011 17:33:52 +0000

thank you Carl for your time, the data type of the ID is varchar but actually we are using correlatives to introduce de ids.
and i use “select * ” because i need all the info not only the ID

thanks again =)

Carl — Mon, 24 Oct 2011 16:58:35 +0000

First you should never use “Select * “. What is the datatype of the column used in the order by clause?

By: Tomoyo

Tomoyo — Mon, 24 Oct 2011 16:38:30 +0000

Hello to all i’m usin this code

select * from ARTICULOS
order by CD_ARTICULO asc

but the result that i have is 1,10,100,125 when the select result must be 1,2,3…10….100,etc why the clause is listing the ids not secuencialy 1,23??
it would be so much apreciated your help.
Thank to you very much =)

rave: Keep it simple; if your users do not request a multi-column order by then I would not use the above solution. Another way would be to use Data binding throught Linq to SQL.

@Carl : How does this affect my performance than an ordinary ORDER BY clause?
Is there any other way to achive this?

Hi Pinal,

I want to execute a set of sql statements depending on the category selected
to achieve this i am using case statement

following are the statements in the stored procedure –

case @cat
when ‘sports’ then
select * from news where type = @cat
when ‘tech’ then
select * from news where type = @cat
end

pls note – i dont want to use dynamic query

the above query not works
i have observed that we can’t use select clause in case statement
whereas we can use case in select statement.

Please clarify me on this

Kind Regards,
D.Mahesh

ORDER BY
CASE –- VARCHAR types ascending
WHEN @OrderBy = ‘ProductNameAsc’ THEN ProductName
END ASC,
CASE –- VARCHAR types descending
WHEN @OrderBy = ‘ProductNameDesc’ THEN ProductName
END DESC,
CASE — INT types ascending
WHEN @OrderBy = ‘QuantityAsc’ THEN Quantity
END ASC,
CASE — INT types descending
WHEN @OrderBy = ‘QuantityDesc’ THEN Quantity
END DESC,
CASE — MONEY types ascending
WHEN @OrderBy = ‘PriceAsc’ THEN Price
END ASC,
CASE — MONEY types descending
WHEN @OrderBy = ‘PriceDesc’ THEN Price
END DESC,
CASE — Default order by
WHEN 1 = 1 THEN ProductName
END ASC

ORDER BY
CASE
WHEN @col=”name” AND @sort=”asc” THEN (RANK() OVER (ORDER BY Name, Status))
WHEN @col=”name” AND @sort=”desc” THEN (RANK() OVER (ORDER BY Name DESC, Status))
WHEN @col=”status” AND @sort=”asc” THEN (RANK() OVER (ORDER BY Status, Name))
WHEN @col=”status” AND @sort=”desc” THEN (RANK() OVER (ORDER BY Status DESC, Name))
WHEN @col=”” THEN (RANK() OVER (ORDER BY Name, Status))
END

Try this…

ORDER BY
CASE WHEN @OrderBy = ‘Option1′
THEN ORDER BY Field1 ASC END, Field 3 ASC
CASE WHEN @OrderBy = ‘Option2′
THEN ORDER BY Field1 DESC, Field 2 DESC END,

Cool idea. This solved my problem.

I was about to give up and code it in the application.

Hey,

I was just wondering if its possible to set value of two variables based on the case ??

For e.g.

WHEN ’00′ THEN @Channel=’ABC’,@Status=’XYZ’

I am a newbee to SQL and I am not getting how to achieve this.
Please let me know the way t do it.
Any help is appreciated.

Thanks,
Mishri
