Trying to calculate cummulative sum in tsql - sql

Question

What am I doing wrong here?
The result is an error, saying:
Msg 102, Level 15, State 1, Line 3 Incorrect syntax near 'order'.
Msg 156, Level 15, State 1, Line 25 Incorrect syntax near the keyword
'as'.
select *
, Antal + Normtid as Flextid
, SUM(antal) OVER (PARTITION BY transdate ORDER BY tekst)
, x = row_number() over (partition by åruge order by tekst)
from
(
select *
,
(
select b.antal
from bi.dbo.Table_pg_FlextidsopgørelseGlUdgave b
where b.tekst = bi.dbo.Table_pg_FlextidsopgørelseGlUdgave.tekst
and b.transdate = bi.dbo.Table_pg_FlextidsopgørelseGlUdgave.transdate
and b.åruge = bi.dbo.Table_pg_FlextidsopgørelseGlUdgave.åruge
and b.type = 'Normtid'
) as Normtid
from
bi.dbo.Table_pg_FlextidsopgørelseGlUdgave
where type = 'afholdt'
and tekst = 'fs'
--and åruge = '201501'
) as data
order by tekst, transdate

Answer 1

It is obvious that you have inappropriate version of Sql Server. Cumulative sums with order by clause like:
SUM(antal) OVER (PARTITION BY transdate ORDER BY tekst)
are only available from Sql Server 2012+.
Actually I can reproduce those errors on Sql Server 2008:
This is on Sql Server 2012:
Notice how the error message changes.

Answer 2

The way you are getting data from derived table is not correct..
EX:
create table
sales
(
id int
)
insert into sales
values
(1),
(2),
(3)
derived table should always have table alias and parent table should refer using from
----this is valid
select
* from
(
select id+1 as id1
from sales
) b
--this is not valid
select
*
(select
id from sales
)b
--Above is valid when you have a subquery say
select
id,(select t1.name from table t1 where t1.id=t2.id)as custname
from table t2
coming to your question..this is not valid.I see both table types are same
select *
,
(
select b.antal
from bi.dbo.Table_pg_FlextidsopgørelseGlUdgave b
where b.tekst = bi.dbo.Table_pg_FlextidsopgørelseGlUdgave.tekst
and b.transdate = bi.dbo.Table_pg_FlextidsopgørelseGlUdgave.transdate
and b.åruge = bi.dbo.Table_pg_FlextidsopgørelseGlUdgave.åruge
and b.type = 'Normtid'
) as Normtid
from
bi.dbo.Table_pg_FlextidsopgørelseGlUdgave
where type = 'afholdt'
and tekst = 'fs'
--and åruge = '201501'
So you can write something like below
select *
, Antal + Normtid as Flextid
, SUM(antal) OVER (PARTITION BY transdate ORDER BY tekst)
, x = row_number() over (partition by åruge order by tekst)
from
(
select * from
(
select b.antal
from bi.dbo.Table_pg_FlextidsopgørelseGlUdgave b
where b.tekst = bi.dbo.Table_pg_FlextidsopgørelseGlUdgave.tekst
and b.transdate = bi.dbo.Table_pg_FlextidsopgørelseGlUdgave.transdate
and b.åruge = bi.dbo.Table_pg_FlextidsopgørelseGlUdgave.åruge
and b.type = 'Normtid'
and b.type='afholdt'
and b.tekst = 'fs'
) as Normtid
order by tekst, transdate
