Exclude nulls from pivoted table - sql-server

Question

I have developed stored procedure as below. I would like to exclude the rows where in each inputdate colum value is null (if there is one input date which is not null, the row should stay). I have no idea how to do that. I serched the web but without any result. Appreciate Your help. Thanks.
create procedure [dbo].[sp_select_staff_time_inputs]
#startDate date,
#enddate date,
#teamid int,
#functionid int,
#servicefunctionid int
as
-- create variables, #columns = inputdates (columns of pivoted table)
DECLARE #columns NVARCHAR(2000)
declare #query nvarchar(4000)
select distinct inputdate into #temp_table_input_dates
from timeinputs
where inputdate >= #startDate and inputdate <= #enddate
order by inputdate
--select * from #temp_table_input_dates
select #columns = isnull(#columns + ',', '') + '[' + convert(varchar,convert(date,inputdate)) + ']' FROM #temp_table_input_dates
--select #columns
create table #temp_table_joins (
soeid varchar(7),
firstname varchar(50),
lastname varchar(50),
teamid int,
team varchar(50),
functionid int,
function varchar(50),
inputdate date,
noofhours float,
servicefunctionid int,
servicefunction varchar(50),
servicephaseid int,
servicephase varchar(50)
)
insert into #temp_table_joins
--select * into #temp_table_joins from
SELECT
u.SOEID, u.Firstname, u.Lastname, u.teamid,
t.team, t.functionid,
f.function,
ti.inputdate, ti.noofhours, ti.servicefunctionid,
sf.servicefunction, sf.servicephaseid,
sp. servicephase
from users u
inner join teams t on u.teamid = t.teamid
inner join functions f on t.functionid = f.functionid
inner join timeinputs ti on u.userid = ti.userid
inner join servicefunctions sf on ti.servicefunctionid = sf.servicefunctionid
inner join servicephases sp on sf.servicephaseid = sp.servicephaseid
--select * from #temp_table_joins
set #query = 'select soeid, firstname, lastname, teamid, team, functionid,
function, servicefunctionid, servicefunction, servicephaseid,
servicephase' + #columns + ' from
(select * from #temp_table_joins

pivot (sum (noofhours) for inputdate in (' + #columns + ')) as asd'
--select #query
--select *, noofhours, userid from timeinputs

I'm not sure, but
DECLARE #columnscondition NVARCHAR(2000)
...
SELECT #columnscondition = isnull(#columns + ' AND ', ' WHERE ') + convert(varchar,convert(date,inputdate)) + ' IS NOT NULL ' FROM #temp_table_input_dates
...
set #query = 'select soeid, firstname, lastname, teamid, team, functionid,
function, servicefunctionid, servicefunction, servicephaseid,
servicephase' + #columns + ' from
(select * from #temp_table_joins
) p'
+ #columnscondition +
'pivot (sum (noofhours) for inputdate in (' + #columns + ')) as asd'
Perhaps, parentheses are missing in the dynamic part.

Thank You valiik.
Your solltion doesn't wok to me as expected but You inspired me to create my own.
Please see below code:
create procedure [dbo].[sp_select_staff_time_inputs]
#startDate date,
#enddate date,
#gvoteamid int,
#gvofunctionid int,
#servicefunctionid int
as
-- create variables, #columns = inputdates (columns of pivoted table)
DECLARE #columns NVARCHAR(2000)
declare #query nvarchar(4000)
DECLARE #columnscondition NVARCHAR(2000)
select distinct inputdate into #temp_table_input_dates
from timeinputs
where inputdate >= #startDate and inputdate <= #enddate
order by inputdate
--select * from #temp_table_input_dates
select #columns = isnull(#columns + ',', '') + '[' + convert(varchar,convert(date,inputdate)) + ']' FROM #temp_table_input_dates
select #columnscondition = isnull(#columnscondition + ' and ', '') + '[' + convert(varchar,convert(date,inputdate)) + '] is not null' FROM #temp_table_input_dates
--SELECT #columnscondition
--select #columns
create table #temp_table_joins (
soeid varchar(7),
firstname varchar(50),
lastname varchar(50),
gvoteamid int,
gvoteam varchar(50),
gvofunctionid int,
gvofunction varchar(50),
inputdate date,
noofhours float,
servicefunctionid int,
servicefunction varchar(50),
servicephaseid int,
servicephase varchar(50)
)
insert into #temp_table_joins
--select * into #temp_table_joins from
SELECT
u.SOEID, u.Firstname, u.Lastname, u.gvoteamid,
t.gvoteam, t.gvofunctionid,
f.gvofunction,
ti.inputdate, ti.noofhours, ti.servicefunctionid,
sf.servicefunction, sf.servicephaseid,
sp. servicephase
from users u
inner join gvoteams t on u.gvoteamid = t.gvoteamid
inner join gvofunctions f on t.gvofunctionid = f.gvofunctionid
inner join timeinputs ti on u.userid = ti.userid
inner join servicefunctions sf on ti.servicefunctionid = sf.servicefunctionid
inner join servicephases sp on sf.servicephaseid = sp.servicephaseid
--select * from #temp_table_joins
set #query = 'select soeid, firstname, lastname, gvoteamid, gvoteam, gvofunctionid,
gvofunction, servicefunctionid, servicefunction, servicephaseid,
servicephase, ' + #columns + ' from
(select * from #temp_table_joins where noofhours is not null
) p
pivot (sum (noofhours) for inputdate in (' + #columns + ')) as asd
where (' + #columnscondition +')'
--select #query
--select #query
--select *, noofhours, userid from timeinputs
execute(#query)
drop table #temp_table_joins
drop table #temp_table_input_dates
