Report Builder 3.0 Forward Dependency Report Parameter - mysql

I have a report that I am working on that will do the following:
Return results based first on the community selected by the user.
Filter to find alike addresses within the community, based on the number of square feet at each address.
Set the end date (a column within the data table) to a user defined parameter for use in a WHERE at the end of the query.
The relevant information is stored in the following places:
Community: ub_subdivision.descr
Address: ub_serv_loc_addr.location_addr
SqFt: arp_ops.dbo.vw_ub_serv_loc_classifications.SqFt
I have setup the query with 3 parameters:
#Community
#Months
#Address
When the user is running the report, the following should happen (in this order):
The community parameter should populate the values stored in ub_subdivision.descr and allow the user to select the community they want from that list.
The address parameter should populate the values within the selected community from step 1, and allow the user to select the address they want from that list.
Based on the selected address, the query should store the value of the SqFt related to this address and use that in the WHERE statement as follows: WHERE (arp_ops.dbo.vw_ub_serv_loc_classifications.SqFt = #Address)
The months parameter should allow for user input to define how many months of data they want. This parameter is called in the query in the WHERE statement: WHERE (ub_bill_run.def_end_dt > DATEADD(m, -#Months, GETDATE())).
If I save the dataset and create a "table report" in Report Builder 3.0 it does the job of recognizing the various parameters and loading them into the Parameters folder and into the Datasets' parameters.
The problem I have is that I am not able to change the parameter properties to display Available Values and select "get from a query". If I go this route, and try to run the query I get an error that I am using "forward dependencies".
I need the #Address parameter to display the address field as the label, but store the sqft field as the value. This is the way I know how to do this and, unfortunately, it doesn't seem to work.
I would appreciate any insight anyone may have.
Thanks!

There is one way to solve this make sure the order should be in the order of
#Community
#Months
#Address
change order to:
#Community
#Address
#Months
just delete existing #month and again add it manually and save it.
i hope it will work for you.

You cannot have parameters based on your main data set.
The forward dependency error is caused because your data set is to be filtered by your parameter, yet it is depending on the same data set to find its' set of values. This is a sort of paradox.
When using queries to define the set of values for your parameters, make sure you create a new data set for each parameter.
Next, make sure the parameters are listed in the order you want them to run. Within the data sets for your parameters, you may use where clauses to make them dependent on one another in the order that they run.
In this example:
Parameter data set for Community:
SELECT DISTINCT ub_subdivision.descr
FROM [YOUR JOINED TABLES]
Parameter data set for addresses:
SELECT DISTINCT ub_serv_loc_addr.location_addr
FROM [YOUR JOINED TABLES]
WHERE ub_subdivision.descr IN (#Community)
Parameter data set for SqFt:
SELECT DISTINCT SqFt
FROM [YOUR JOINED TABLES]
WHERE ub_subdivision.descr IN (#Community)
AND ub_serv_loc_addr.location_addr IN (#Address)
You should also make a month data set for your #month parameter, however it is not dependent on the other parameters so I will leave that to you.
Hope this helps!

Searching a database in Report Builder 3.0

I am not sure if this is possible in Report Builder or not. I want to put a text box in a Report Builder report and then search the database for a specific person and display that in a subreport. Is this possible and, if so, how would you suggest I do it? I have tried researching it online without success.
This part will produce a parameter into which your user can type whatever they want
You need to set up your report to use parameters. You can set these parameters up to require user input either from manual entry or by picking from a pre-defined list.
Assuming you are returning your data using a SQL query, you can then reference these parameters in your dataset script. If for example you had a parameter called FirstName and another called Surname, and you only wanted to return values in your data set that matched both exactly, you would reference these parameters like so:
select PersonID
,FirstName
,Surname
,OtherDetails
from PersonTable
where FirstName = #FirstName
and Surname = #Surname
If you would rather have more of a 'search' type function, you can use the SQL like operator and wildcards, though bear in mind this will have a potentially very detrimental effect on your query performance:
select PersonID
,FirstName
,Surname
,OtherDetails
from PersonTable
where FirstName like '%'+#FirstName+'%'
and Surname like '%'+#Surname+'%'
This part shows you how to change that parameter so it provides a drop down menu. This part is optional.
If you want to provide a list of available options to select from, you can create a parameter that has a list of 'Available Values'. These can either be manually typed in by yourself - hard coding them in to the report design - or you can make them data driven by basing the parameter on a second dataset.
To get that list of people, you would want to return the ID of the person you are looking for as well as the details that are end-user friendly to be visible in the report:
-- select distinct so we have no duplicates
select distinct PersonID as Value -- Value is what is used to the query. This ideally will be a uniquye identifier
,FirstName
+ ' '
+ Surname as Label -- Label is what the user sees. This can be a bit more verbose and detailed
from PersonTable
order by Surname -- Specify how you want the options ordered
,FirstName
If you set this dataset as the source by selecting Get Values From A Query in the parameter options, you will see the drop down list appear when you run the report. Users can then select one, click Run Report and have their selection impact the data that is returned.

Filter data set by month

I'm using an embedded data source of type SharePoint List.
I use a parameter that a user can modify that will filter the data set by the month. I've seen a few examples but they all either use a SQL query or only filters on the exact day rather than the month.
I added a parameter ParamMonth and gave it the data type of Date/Time. I can see this adds a drop down box to my report which is exactly what I want. Ideally, I would like to add the name of all 12 months or something similar, but I don't know how that will work out when the data exceeds a single year. Now, that I've got my Report Parameter added, I need to add it to my dataset to filter on. This is where I'm stuck.
An easy way could be creating a parameter type Integer and set all months in Available Values tab as follows (I just set five months for example).
Then go to the DataSet Properties / Filter tab and use the below settings.
For expression use:
=MONTH(Fields!Date.Value)
Where Date is the field that you will use to filter by month. In Value you have to use:
=Parameters!Month.Value
UPDATE: Provide year selection.
The best approach for this is getting the available values from a DataSet, in this case your SP list.
Just create a calculated field in your dataset with available years (it can be a copy of the SP list dataset), call it calculatedYear and use:
=YEAR(Fields!Date.Value)
Now create a Year parameter of Intenger data type, and set this settings:
Where DataSet15 is the DataSet name that feeds your parameter with the available years.
Then just add another filter in your dataset:
Note you will need two datasets one to get the available years and
other the dataset you need to filter.
Let me know if this helps.

Dynamically change column names as week number on every weekly run

I want to build a SSRS report that has column as week numbers - 8 weeks for 8 columns starting with current. This report is run every week and current week number is set then. So both column names and their values should change .Is it possible to build something like this in SSRS?
I tried doing this with a dynamic SQL based stored proc in dataset. However for every run I don't even see the columns values updating dynamically
Here's an example :
Also I am trying to avoid these week numbers as row values and then using matrices
My stored proc looks something like this
declare #n tinyint = datepart(wk, getdate())
declare #n1 tinyint = (#n+1), #n2 tinyint =(#n+2), #n3 tinyint =(#n+3), #n4 tinyint =(#n+4), #n5 tinyint =(#n+5), #n6 tinyint =(#n+6)
exec ('Select b.sku, b.['+#n+'], b.['+#n1+'], b.['+#n2+'], b.['+#n3+'], b.['+#n4+'], b.['+#n5+']...
Will appreciate any help in this direction.. many thanks!
When working with SSRS it's generally best to avoid dynamic SQL and pivoting the data in the SQL. Use the SQL to get the raw data you need and then let SSRS do the pivoting and aggregation. This way you take advantage of what they each do best. I know you said you want to avoid matrices, but it is the best way to make the report dynamic.
So you should either return all the data in one dataset and use filters on your matrices OR write two queries and have each one populate a matrix. BTW a matrix is just a table with a column group added, so don't be intimidated by them.
There are 2 ways to do this with a standard tablix.
Calculate the column headers as expressions using concatenation of Wk and some date math to find the correct week number and return the same sort of thing from your query (e.g. columns are current_week, week_minus_1, week_minus_2...)
Return the column headers as additional columns in your query that are the same value for every row (e.g. ColHeader0, ColHeader1...). Your data columns would still be relative weeks (e.g. ValueWeek0, ValueWeek1...). In your report the column header would have an expression like =First(Fields!ColHeader0.Value). This is a more flexible approach since it lets you pick 8 historical weeks instead of only the last 8 weeks if you add a parameter.
EDIT - Clarifications
The reason that you get the blank column Wk48 is approximately that you have created your report looking for that column that won't be there the next time. SSRS looks for exact columns. You should you use relative column names for either of the options I have specified:
exec ('Select b.sku, b.['+#n+'] as Wk0, b.['+#n1+'] as Wk1, b.['+#n2+'] as Wk2, b.['+#n3+'] as Wk3, b.['+#n4+'] as Wk4, b.['+#n5+'] as Wk5...
This will allow you to populate the aliased Wk0 column with the appropriate current week data and still make sure that it can be consistently referenced as the base week by SSRS.
To change the column headers you can:
Independently calculate the week numbers in SSRS in the column header expressions: ="Wk" + CStr(<correct week calculation>).
Return the column headers in the result set and access them in the column header expression:
exec ('Select b.sku, b.['+#n+'] as Wk0, b.['+#n1+'] as Wk1, b.['+#n2+'] as Wk2, b.['+#n3+'] as Wk3, b.['+#n4+'] as Wk4, b.['+#n5+'] as Wk5..., ''Wk'''+#n+' as ColHeader0, ''Wk'''+#n1+' as ColHeader1...
and reference the returned column headers from the SSRS column header expression as =First(Fields!ColHeader0.Value).
Here's a solution that worked for me:
Create parameters (say CurrWk, CurrWk1) ,set as hidden and store 'Default value' and 'Available value' equals to current week number (datepart(wk, now()) and any subsequent week by doing a +1, +2, +3.. etc.
Write a query expression . Click onto fx beside dataset query space and write the select query for your program embedding parameter values in the expression window. For eg ="Select SKU, [" & Parameter!CurrWk.Value & "] as Wk1,
[" & Parameter!CurrWk.Value & "] as Wk1 from Sales_Table"
Before passing this query as a 'command text expression' please ensure this query is working in sql ssms.
Save the expression. Now find 'Fields' tab on the left hand side panel.You need to map the fields manually from the query here. If this is not done, there is a very high chance you seean empty field list and wont be able to access them at all. This may be because ssrs do not store query metadata directly from expressions.
You can avoid part of the issue by having atleast the static fields , for example here SKU listed in the 'Fields' list by first running a sql query with static field(select SKU from Sales_Table ). You can then go back to update dataset- change query to expression and embed the parameterized field names.
Map field names. In this example I chose 'Query Type' fields and set Field names as SKU, CurrentWeek, NextWeek and mapped to source SKU, Wk and Wk1 respectively.
Click on 'Refresh Fields' at the bottom. Now you have a dataset with the complete field list. Use these in charts, tables . Run it every week and note the numbers changing as expected.
In case you are using this dataset in a table, make sure you set headers with Labels of Parameters (for eg here I did =Parameters!CurrWk.Label for col with current week data)
That's it!

Passing multiple values using URL to a drop down parameter in SSRS

I am trying to pass multiple values for a parameter in ssrs which is delimited by ','.Limiting the result data set using where condition using split function in stored proc, this gives me results of my report data set
WHERE YEAR(a.month_start_date)IN (SELECT Value FROM dbo.FnSplit(#year,','))
--AND datename(month,month_start_date) IN (SELECT Value FROM dbo.FnSplit(#month,','))
AND b1.branch_cd IN (SELECT Value FROM dbo.FnSplit(#branch,','))
I created a data set to get available values for year filter
Configured the parameter to get available values from my filter data set and also checked option to "Allow multiple values"
Select distinct year(month_start_date) as Year
From [DB].[dbo].[table]
Then I also limited my report data set to accept parameters with following condition.I configured parameter to accept the following value
=Join(Parameters!year.Value,",")
I pass in values in url
http://<servername>/ReportServer/Pages/ReportViewer.aspx?<reportname>rs:Command=Render&year=2012,2013,2014
My filter does not select the values passed thru the url. The report only shows me the list of values in drop down but does not select the values parsed thru url
I am not sure if I am missing anything else. Please suggest.
Thanks!
The issue here is that your URL is constructed incorrectly. You are trying to pass througth the years as a single parameter and that isn't how it works. Pass it through as a whole heap of parameters and then let the reporting server put it together and put it into the SQL.
Your URL should look like this (I changed the : to %3a and broke up the year parameter)
http://<servername>/ReportServer/Pages/ReportViewer.aspx?<reportname>rs%3aCommand=Render&year=2012&year=2013&year=2014
I hope this helps someone out.

Fields cannot be used in report parameter expression

I have to set the start_date of my report depending of a report parameter. The time stamps are calculated in a database query.
My expression looks like this:
=SWITCH (
Parameters!report_type.Value = 1,First(Fields!daily_start.Value, "Timestamps")
,Parameters!report_type.Value = 2,First(Fields!weekly_start.Value, "Timestamps")
,Parameters!report_type.Value = 3,First(Fields!monthly_start.Value, "Timestamps")
)
Unfortunately I get the error message:
A value expression used for the report parameter 'time_from' refers to a field. Fields cannot be used in report parameter expression
I know, that this is not allowed because SSRS cannot be sure in which order datasets are called. But I think this is not dangerous.
All time stamps are received by query without parameter. The parameter report_type is selected by a user before the report will be generated.
Can someone give me a hint for a workaround?
Here's the workaround - get the value using SQL.
Create a new Dataset called StartDates:
SELECT CASE
WHEN #report_type = 1 THEN daily_start
WHEN #report_type = 2 THEN weekly_start
WHEN #report_type = 3 THEN monthly_start
END AS StartDate
FROM MyTable
You already have the #report_type and #time_from parameters. With the #time_from parameter, set its Default Values to Get values from a query using the StartDates dataset and the Value field StartDate.
Now, you'd think this might be enough to make it work - you're referencing this query as the default value and as you change the #report_type parameter the other parameters refresh, but the first date in the #time_from parameter never changes. That's because the refresh happens on the Available Values query, not on the Default Values query.
So you also need to wire up the Available Values query to the StartDates query. Now your query will fire on the change of #report_type and the default value will be set to the appropriate date for your selection.
I switched from a query to Stored Procedure and was getting this error. Things I tried:
Ensured I had sufficient permission on the database (you need EXEC rights or DBO to run teh sproc)
Delete the existing parameters (and then use refresh fields to refresh/get the correctly named ones back)
Remove the square brackets around the stored procedure if you've specified that
Sometimes, Expressions can get a bit verbose. I have created a Report Code Function and then used that as the Parameter Value.
For example, I created a Code function called "CalculateDateSet" and then set the Report Parameter to this expression:
"=Code.CalculateDateSet(Parameters!Month.Value, Parameters!Year.Value"
