Count Item function

Question

Hi,

I need to count the number of rows in my Item table. The following statement gives me the number i.e. 200.

Select Count(*) As Counter
From Item
Group By Id

How can I number each individual row so that the row will have a number next to it i.e.

Select Count(*) As Counter,[Count Statement] as Number of the Row
From Item
Group By Id

Thanks

 

Answer 1

Is this what you want?

SELECT Row_NUMBER() OVER(Order by a.id) as series_No, a.id, b.myCount

FROM items a

LEFT JOIN (SELECT COUNT(*) as myCount, id

FROM items

group by id) b ON a.id=b.id

Answer 2

I am not sure, I get the following error.

Server: Msg 195, Level 15, State 10, Line 1
'Row_NUMBER' is not a recognized function name.
Server: Msg 170, Level 15, State 1, Line 9
Line 9: Incorrect syntax near 'b'.

Answer 3

Row_Number() is a new function in SQL Server 2005.

Try this one:

SELECT (select count(*) from items as t2

where t2.items <= t1.items )+1 as series_No, t1.id

FROM items t1

ORDER BY t1.items

Thanks, that helped.

You should actually do this on the client-side where it is easier and it will perform better. Simply return the rows in a sorted manner and then number them on the client side.
