SSRS 2008: How to create parameter based on another parameter - tsql

Question

I know others have asked similar questions, but I have tried their solutions and it still is not working for me.
I have one parameter called "Region" which uses the "region" dataset and another report parameter called "Office" which uses the "office" dataset.
Now I want "Office" list of values to filter based on "Region" selection. Here is what I did so far. For the region dataset, it returns "regions_id" and "region_description". Then for "Region" report parameter, I selected "Text" datatype and allow Null values. This may be a mistake to select "text" since this is a uniqueidentifier value. For available values, I selected the region dataset and regions_id for value, region_description for label. I went to Advanced tab and selected "Always refresh". And on Default tab, I entered "(Null)", for when they want to see all regions.
NExt, I created a report parameter called "regions_id2", allow null values, and I set available values = region dataset. For values and label both, I specified the regions_id. For default value, I again entered "(Null)". And I again selected "Always refresh".
Finally, I added this "regions_id2" parameter to the "office" dataset. And then the office report parameter uses the "office" dataset with available values. Value field = "group_profile_id" and label field = "name_and_license". Default values = "(Null)". Advanced "Always refresh".
And I ordered these report parameters in this same order: Regions, regions_id2, and Office. But now when I run this report I get no errors, however, the list of offices includes all of the offices regardless of what I choose for regions. Here is my T-SQL for these datasets:
CREATE Procedure [dbo].[rpt_rd_Lookup_Regions]
(
#IncludeAllOption bit = 0,
)
As
SET NOCOUNT ON
If #IncludeAllOption = 1
BEGIN
Select Distinct
NULL AS [regions_id],
'-All-' AS [region_description]
UNION ALL
SELECT Distinct
[regions_id],
[region_description]
FROM [evolv_cs].[dbo].[regions]
Where [region_description] not in ('NA','N/A')
Order By [region_description]
END
Else
BEGIN
SELECT Distinct
[regions_id],
[region_description]
FROM [evolv_cs].[dbo].[regions]
Where [region_description] not in ('NA','N/A')
Order By [region_description]
END
CREATE Procedure [dbo].[rpt_rd_Lookup_Facilities]
(
#IncludeAllOption bit = 0,
#regions_id uniqueidentifier = NULL
)
As
SET NOCOUNT ON
If #IncludeAllOption = 1
BEGIN
Select
Null As [group_profile_id],
Null As [profile_name],
Null As [license_number],
Null As [other_id],
--Null As [Regions_id],
'-All-' As [name_and_license]
UNION ALL
SELECT
[group_profile_id],
[profile_name],
[license_number],
[other_id],
--[regions_id],
[profile_name] + ' (' + LTRIM(RTRIM([license_number])) + ')' As [name_and_license]
FROM [evolv_cs].[dbo].[facility_view] With (NoLock)
Where [is_active] = 1 and (#regions_id is NULL or #regions_id = [regions_id])
Order By [profile_name]
END
Else
BEGIN
SELECT
[group_profile_id],
[profile_name],
[license_number],
[other_id],
[regions_id],
[profile_name] + ' (' + LTRIM(RTRIM([license_number])) + ')' As [name_and_license]
FROM [evolv_cs].[dbo].[facility_view] With (NoLock)
Where [is_active] = 1 and (#regions_id is NULL or #regions_id = [regions_id])
Order By [profile_name]
END
What could I possibly be doing wrong?

Answer 1

I fixed this by selecting the region parameter value from region dataset for the office dataset
