Parameter Value to select project number range - reporting-services

I have a parameter asking the user if they would like to "only" include project numbers below 5000.
If they say yes, then I need the parameter to adjust the project field to be <=5000. If they say No, then the project number field should be <=99999999.
I am not sure how to accomplish this, right now I have a dataset where project number = #projnum, and I have #projnum parameter with two values of Yes and No.
I attempted to put an expression on the dataset properties under that specific parameter as:
=iif(Parameters!projnum.Value=1, <9999, <9999999999)
but I get a syntax error when using the < sign. It will work with just a number.
Sorry, new to SSRS and cannot figure this one out.

Why not change your dataset query to use <=:
SELECT *
FROM YourTable
WHERE ProjectNumber <= #projnum
Then adjust your parameter values to the range values:

Filtering out results based on length of reference number

I have a report, in report builder, where I am getting duplicate rows based on the reference number.
In the below example, is there anyway that I can remove any reference number that is longer than 9 digits using an expression, I've looked into using LEN but cant seem to make it work for me! I am very new to SQL and report builder.
You can use a Filter on either the Dataset or the object (table, chart...).
The Filter Expression would be the LEN of you field - =LEN(Fields!HB-RENT-REF.Value)
The Type would be Integer.
The Operator would be <=.
And the Value would be 9.
This would only allow records with a HB-RENT-REF field length of 9 or less.
MS Docs: Dataset Filter
If you're using SQL scripts or procs to build your report, then you could simply include a WHERE clause that checks for if the length of your column, using the LEN() method, is less than or equal to your condition. So something along these lines:
SELECT *
FROM YourTable AS yt
WHERE LEN(yt.YourColumn) <= 9;
You will want to replace the * with the specific columns you want and use the appropriate tables too of course. But that's the general idea of checking for length in a WHERE.

Filter Multivalue Parameter on Dataset

So I have a multiple value parameter than contains 3 options. >250K, <250K, >2M.
I also have a table that consists of multiple columns.
. Because the parameter is a multivalue, i am having difficulties filtering the dataset.
I need to filter the dataset by checking, (if > 250K is selected, filter the dataset accordingly), (if < 250K is selected, filter the dataset accordingly) and (if > 2M is selected, filter the dataset accordingly).
I was told to use a join and split on the parameter within the (>250K condition, then do a contains to see if it contains any of the parameter values) but I am not as advanced in my knowledge of coding to be able to do that.
Any Suggestion? Thanks in Advance
I previously tried the method below but then i came to realise that it wont work because the parameter is a multi value.
I know its been a while since you raised this, you were on the right track but all you should need to do is add a filter to the Tablix on the field you will be filtering, use the 'in' operator and in the Value type [#Yourparametername] the square brackets and case sensitivity are important. Also ensure the expression type is correct, in your case it looks like you are using Integer. The image should help.
If you want to use multi-parameters, In the dataset, you can read parameter value using JOIN.
Example:
If you want to read multiple values for #MyParamter in a dataset given in the following example:
Dataset Parameters
you need to use =JOIN(Parameters!myMultiParamter.Value,",") as an expression to read all selected values in CSV form.
Expression
Now the #ParameterValues param has all selected values as comma separated values and you can use them in your dataset code as per design requirements.
Note: It's not necessary to use a comma but u can use anything you want to separate values.
Your sql query where should look like
Where
(
(0 IN (#Parameter) AND ValueColumn<250000)
OR
(1 IN (#Parameter) AND ValueColumn>=250000)
OR
(2 IN (#Parameter) AND ValueColumn>=2000000)
)
One parameter
Two parameters
All parameters
Once you return the value you can also use charindex or patindex* and look for where the value in your where clause is a pattern where the index number is > 0 . For instance if the returned string from SSRS is '01,02,03' and then your where clause has something like this right(field, 2) which would result in value '03'. you change your where clause to be where patindex('%' + right(field, 2) + '%', #returnedstring) > 0 which will give you results. The keeps you from having to parse apart the #returnedstring parameter in your sql code.

Report Builder 3.0 Forward Dependency Report Parameter

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!

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"

SSRS: Get values from a particular row of DataSet?

My dataset currently has 12 rows of data. Each representing data for a month. I would like to have variance of a column between to rows, the rows being last & last but one i.e., latest month and previous month's data.
It could have been simple if I were to work on tablix but thats not the case. I want those values for a textbox.
Any ideas on it anyone?
I hope you are using SSRS 2008R2:
R2 introduced the Lookup function that is perfect for this scenario.
=Lookup( Fields!ProductUID.Value ,Fields!ProductID.Value,Fields!Price.Value,"PriceDataSet")
The Lookup function above will evaluate the first parameter ("Fields!ProductUID.Value") in the current dataset, then look for a matching value in the field specified in the second parameter ("Fields!ProductID.Value") in the dataset specified in the fourth parameter. The value of the third parameter is then evaluated in that row of the dataset and returned.
A little convoluted, but very helpful.
In your case, you can use this in a textbox with a calculated a static number:
=Lookup(
Month(DateAdd(DateInterval.Month, -1, GetDate())),
Fields!MonthID.Value,
Fields!Name.Value,
"DataSet1")
This should calculate a number for last month, then look for a match in DataSet1.
In this example I have a tablix with Statecode and name as below
enter image description here
Suppose you want to display the name of state of CA, write an expression as -
=Lookup(
"CA" ,
Fields!StateCode.Value,
Fields!StateName.Value,
"ReportData"
)
This will return 'California' in the text box
I ran across this post while trying to solve a similar problem but with columns of double data type. Not sure why but SSRS did not want to return my first row using LOOKUP in combination with ROW_NUMBER in SQL(If someone can solve that all the better). I ended up using a SUM(IIF) instead. Hopefully, this is useful for someone else.
=Sum(IIF(Fields!RowNum.Value=1,CDBL(Fields!MyNumericColumn.Value),CDBL(0)))
Note: If SSRS complains about data types, just cast both parts of the IIF to the desired data type.
