Multiple Choice and Hidden Reports - sql

Question

I have specified the Values in the Which Report Parameter
Label Value
Occupancy Occupancy
Pitch Nights Sold PitchNightsSold
Capacity Capacity
Pitch Nights Sold And Capacity PitchNightsSoldAndCapacity
Pitch Nights Sold And Occupancy PitchNightsSoldAndOccupancy
Pitch Nights Sold Capacity And Occupancy PitchNightsSoldCapacityAndOccupancy
Main Dataset:
SELECT
OccupancyDetail.CalendarYear,
OccupancyDetail.CalendarMonth,
SUM(OccupancyDetail.No_of_Nights) AS No_of_Nights,
SUM(OccupancyDetail.Capacity) AS Capacity
FROM
OccupancyDetail INNER JOIN
Site ON OccupancyDetail.Site_Skey = Site.Site_Skey
WHERE (OccupancyDetail.ReferenceDate = convert(Date,getdate()))
AND CASE WHEN #Time = 'YEAR' THEN CAST(CalendarYear as varchar(4)) else CalendarMonth + ' ' + CAST(CalendarYear as varchar(4)) end in (#Dates)
AND ((#ReportingLevel = 'BDM' AND Site.BDM in(#BDM_Region_Site))
OR (#ReportingLevel = 'Region' AND Site.Region in (#BDM_Region_Site))
OR (#ReportingLevel = 'SiteName' AND Site.SiteName in (#BDM_Region_Site)))
GROUP BY OccupancyDetail.ReferenceDate,OccupancyDetail.CalendarYear, OccupancyDetail.CalendarMonth
Time Dataset:
select
DateChoice
FROM
(
select distinct
CalendarYear,
1 as MonthNumber,
CAST(CalendarYear as varchar(4)) as DateChoice
from Time
where #Time = 'YEAR'
union all
select Distinct
CalendarYear,
MonthNumber,
CalendarMonth + ' ' + CAST(CalendarYear as varchar(4)) as DateChoice
from Time
where #Time = 'MONTH'
) as QRYDATA
ORDER BY CalendarYear,MonthNumber
Site Dataset:
SELECT DISTINCT BDM AS SiteInfo FROM Site
WHERE #ReportingLevel = 'BDM'
UNION ALL
SELECT DISTINCT Region FROM Site
WHERE #ReportingLevel = 'Region'
UNION ALL
SELECT DISTINCT SiteName FROM Site
WHERE #ReportingLevel = 'SiteName'
On Report Builder 3.0 I have created 6 reports that are hidden unless it is selected in a parameter:
Report Code Visibility string:
=iif(Parameters!WhichReport.Value(0) = "Occupancy", False, True)
But what I want to do is make the Parameter a multiple select parameter so someone can choose two charts instead of 1 or choose all 6 etc but whatever selection is made all other reports need to stay hidden. Can this be done and if so how?
Thanks

Answer 1

You can modify the Hidden expression to achieve this:
Turn all the selected reports into a string using Join, then check if the relevant report name is in the string, something like:
=IIf(
InStr(Join(Parameters!WhichReport.Value, ","), "Occupancy Report") > 0
, False
, True
)
Or, for a different item:
=IIf(
InStr(Join(Parameters!WhichReport.Value, ","), "Capacity Report") > 0
, False
, True
)
Edit after comment:
I guess you're getting mismatches as values like PitchNightsSold and PitchNightsSoldAndCapacity will confuse the expression as written.
I would use a Dataset similar to the following to control item visibility:
Label Value
----- -----
Occupancy Chart1
Pitch Nights Sold Chart2
Capacity Chart3
Pitch Nights Sold And Capacity Chart4
Pitch Nights Sold And Occupancy Chart5
Pitch Nights Sold Capacity And Occupancy Chart6
Then expressions like:
=IIf(
InStr(Join(Parameters!WhichReport.Value, ","), "Chart1") > 0
, False
, True
)
Will only ever apply to one item.
Since these are your own internal constant values, you can call them whatever you want; just make them distinct and unambiguous. The label will remain unchanged so users will be unaffected when running the report.
Edit after comment:
In a comment #glh offers a good solution to similar Value values:
...if you wrap you join in commas and search for them this will remove
the partial finds.
So something like:
=IIf(
InStr("," + Join(Parameters!WhichReport.Value, ",") + ",", ",PitchNightsSold,") > 0
, False
, True
)
Would work very well, too; credit to him for the suggestion.
