Hi,

a.
 I have a drop down multivalued parameter. the items in this parameter must be hard coded and not coming from a dataabase.
 e.g.:  
All
CurrentFriday
 NextFriday

how can this be done?

b.
 I want to hide the 'Select All' which is placed by default when you select multivalued parameter. How can this be done?

c.
when I send it to stored procedure, I need to check an Enddate column.
if enddate is less than today then set columnX to 'currentFriday' otherwise to next friday.
I need to do it within the query.

Thanks in advance

a: I usually hardcode this in a query then configure the report parameter based on the dataset, easier for maintenance:

select 'Current Friday' as Label, 'CF' as Code
union all
select 'Next Friday', 'NF'

b: you can't, it comes for free when you check the multi-value checkbox.  Why would that be an issue? (this only has effect on the user interface)

c: check this

SET DATEFIRST 7;    
declare @enddate date = '2014-01-01';
declare @currentdate date = getdate();

select case when @enddate < getdate() then dateadd(dd,6-datepart(dw,@currentdate)-7,@currentdate) 
	else dateadd(dd,6-datepart(dw,@currentdate),@currentdate) end CF_or_NF
	, dateadd(dd,6-datepart(dw,@currentdate),@currentdate) as NextFriday
	, dateadd(dd,6-datepart(dw,@currentdate)-7,@currentdate) as CurrentFriday

Thank but I don't need to do date calculations.

I have 2 issues:

I have a column of type udt_fuzzydate(char 8)

I have to do conversion before comparing, here is actual code but it doesn't work:
(Error: conversion of varchar datatype to a datetime data type resulted in an out of range value)
Select x
, y
, z
, (Select case when
( isdate(end date)= 1 and convert(datetime, enddate) > getdate()) or
(isdate(end date)= 1 and convert(datetime, enddate) = null)
Then 'current'
Else 'next'
End) as type
,.....
From tble1,.....

Other issue is that I pass the type (current, next or all) from report parameter to query and now I need to check which record in above conversion and comparison matches the selected parameter in the report???

"Thank but I don't need to do date calculations."

Erm...

"if enddate is less than today"

That IS a date calculation...

I understand that the data type of enddate is udt_fuzzydate(char 8)?  What does such a value look like?

PS: I recommend you to focus on one issue per question.  In this one I see at least three...

Thanks for your a and b.

c. this is how I solved it:

(select case when isdate(ENDDATE)=1 then (case when convert(datetime, ENDDATE) > getdate()
                                                                              then 1
                                                                              else 2
                                                                                end)
                                                              else 1  
                                                              end) as X
