Report Builder 3.0 optional parameter - sql-server

is there a chance to use optional parameters in report builder?
for example: i have a query with 3 parameters
#Pa1 date
#Pa2 date
#Pa3 varchar(3)
if i run View report without inform one of then i got the message:
Select a value for the parameter #Pa3 (for example)
is it possible?
I tried to use a empty field but i got no data
select a.legajo,c.nombres,e.Descripcion,CONVERT (char(10), a.fecha, 103) as Fecha,a.hora as ENTRADA,
b.hora as SALIDA,
DATEDIFF(HOUR,a.hora,b.hora) as Horas_trabajadas,
c.hor_x_jor Horas_jornada,
DATEDIFF(HOUR,a.hora,b.hora) -hor_x_jor as Diferencia
from fichadas_in a, fichadas_out b, empleados c,sucursales d,Clasificacion e
where a.Legajo=b.Legajo
and a.fecha=b.fecha
and a.fecha between #fecha1 and #fecha2
and d.codigo=#sucursal
and a.legajo=c.legajo
and c.CCO=d.Codigo
and e.Codigo=c.Clasif
Order by a.fecha,legajo

Allow Null Values or Blank values for your parameter.

As already mentioned you need to select ALLOW BLANK VALUES, and ALLOW NULL VALUE.. But you also have to ensure your SQL knows what to do with those VALUES in your WHERE clause.
AND (
((#Pa3 IS NOT NULL AND #Pa3 != '') AND d.codigo = #Pa3)
OR
((#Pa3 IS NULL OR #Pa3 = '') AND d.codigo LIKE '%'))
)
There are other ways to do this, but make sure you account for those values/lack of values.
For the date range, I would recommend declaring another variable that calculates what the date value is before running the SELECT statement.. Create a variable that is calculates what the value is if the value is blank, null, or entered.
The variable may go in to #Pa1 but then calculates into #fecha1, then in the WHERE clause you us #fecha1.

Snowflake Numeric value '' is not recognized

Please help me with error 'Numeric value '' is not recognized'.
In Snowflake i am having a variable day_minus which holds a number, using this i want to return date value of current_date minus the value given in the variable.
If there is Null or empty passed in the variable i want to get current date minus 1.
For this i have written a code like below. But it throws me an error Numeric value '' is not recognized
But it throws an
set day_minus=7;
SELECT DATEADD(DAY, concat('-',nvl(nullif(try_to_number($day_minus) ,''),1)),current_date() );
Can you please correct me where i am doing mistake
you can use case statement
SELECT DATEADD(DAY, concat('-',nvl(case when $Units ='' then 1 else $Units end ,1)),current_date() );
If you use concat then the result is always going to be a string. If you want to set the "default" value to -1 then just put -1 in your code.
The try_to_* functions take a string as their input so you'd need to make your variable a string to make this work e.g.
set day_minus='7';
You don't need nullif at all. So the final version would be something like:
set day_minus='7';
DATEADD(DAY, nvl(try_to_number($day_minus),-1),current_date() );

Issue with dataset Creation

I am new to ssrs and having difficulty defining parameters. I am trying to develop a code which will determine the parameters based on report type value 1 or 2.
I tried defining the parameters at run time using variables but no luck
SELECT A.PRV_TIN_NO,
B.CLM_PD_DT,
A.CLM_FROM_DOS_DT,
a.CLM_THRU_DOS_DT,
A.GRP_NO
FROM CBDW.CBDW_CLM_MEDCL_HDR A
INNER JOIN CBDW.CBDW_CLM_MEDCL_HDRLN B
ON A.GRP_NO = B.GRP_NO
WHERE (
(#reporttype=1
AND A.GRP_NO = #grpNo
AND b.CLM_PD_DT >= #PaidfromDate
AND b.CLM_PD_DT <=#PaidToDate
)
OR
(#Reporttype=2
AND A.GRP_NO = #grpNo
AND a.CLM_FROM_DOS_DT>=#fromDate
AND a.CLM_THRU_DOS_DT <=#ToDate
AND b.CLM_PD_DT <=#PaidToDate
)
)
I am expecting to ssrs to prompt report type and when I select 1 parameters should be groupnumber and claim paid start date and end date while in option 2 I should also have service date parameter/

Filter SQL datatable according to different parameters, without a WHERE clause

I'm building an application that needs to allow the user to filter a data table according to different filters. So, the user will have three different filter posibilites but he might use only one, or two or the three of them at the same tame.
So, let's say I have the following columns on the table:
ID (int) PK
Sede (int)
Programa (int)
Estado (int)
All of those columns will store numbers, integers. The "ID" column is the primary key, "Sede" stores 1 or 2, "Programa" is any number between 1 and 15, and "Estado" will store numbers between 1 and 13.
The user may filter the data stored in the table using any of those filters (Sede, Programa or Estado). But the might, as well, use two filters, or the three of them at the same time.
The idea is that this application works like the data filters on Excel. I created a simulated table on excel to show what I want to achieve:
This first image shows the whole table, without applying any filter.
Here, the user selected a filter for "Sede" and "Programa" but leaved the "Estado" filter empty. So the query returns the values that are equal to the filter, but leaves the "Estado" filter open, and brings all the records, filering only by "Sede" (1) and "Programa" (6).
In this image, the user only selected the "Estado" filter (5), so it brings all the records that match this criteria, it doesn't matter if "Sede" or "Programa" are empty.
If I use a SELECT clasuse with a WHERE on it, it will work, but only if the three filters have a value:
DECLARE #sede int
DECLARE #programa int
DECLARE #estado int
SET #sede = '1'
SET #programa = '5'
SET #estado = '12'
SELECT * FROM [dbo].[Inscripciones]
WHERE
([dbo].[Inscripciones].[Sede] = #sede)
AND
([dbo].[Inscripciones].[Programa] = #programa)
AND
([dbo].[Inscripciones].[Estado] = #estado)
I also tryed changing the "AND" for a "OR", but I can't get the desired result.
Any help will be highly appreciated!! Thanks!
common problem: try using coalesce on the variable and for the 2nd value use the field name you're comparing to. Be careful though; Ensure it's NULL and not empty string being passed!
What this does is take the first non-null value of the variable passed in or the value you're comparing to.. Thus if the value passed in is null the comparison will always return true.
WHERE
[dbo].[Inscripciones].[Sede] = coalesce(#sede, [dbo].[Inscripciones].[Sede])
AND
[dbo].[Inscripciones].[Programa] = coalesce(#programa, [dbo].[Inscripciones].[Programa])
AND
[dbo].[Inscripciones].[Estado] = coalesce(#estado, [dbo].[Inscripciones].[Estado])
If sede is null and programa and estado are populated the compare would look like...
?=? (or 1=1)
?=programa variable passed in
?=Estado variable passed in
Boa Sorte!
Thank you all for your anwers. After reading the article posted in the comments by #SeanLange I was finally able to achieve what was needed. Using a CASE clause in the WHERE statement solves the deal. Here's the code:
SELECT
*
FROM [dbo].[Inscripciones]
WHERE
([dbo].[Inscripciones].[Sede] = (CASE WHEN #sede = '' THEN [dbo].[Inscripciones].[Sede] ELSE #sede END))
AND
([dbo].[Inscripciones].[Programa] = (CASE WHEN #programa = '' THEN [dbo].[Inscripciones].[Programa] ELSE #programa END))
AND
([dbo].[Inscripciones].[Estado] = (CASE WHEN #estado = '' THEN [dbo].[Inscripciones].[Estado] ELSE #estado END))
AND
([dbo].[Inscripciones].[TipoIngreso] = (CASE WHEN #tipoingreso = '' THEN [dbo].[Inscripciones].[TipoIngreso] ELSE #tipoingreso END))
Thanks again!!

Update query failed '0' rows affected

I am trying to run this query but the query keeps giving up on me:
Update StockInvoiceInfo set Quantity = Quantity - 2 where p_id = 5 AND ProductDate = convert(Cast('31-5-2015' as datetime)) ;
After Running this code it returns an error below:
Incorrect syntax near '31-5-2015'
The datatype of the ProductDate column isDate. I am using Sql Server 2012.
You have used Convert functions but didn't supplied it with parameters. Also there is no need for this function here. Also take care of date format. I have changed it to standard format:
Update StockInvoiceInfo set Quantity = Quantity - 2
where p_id = 5 AND ProductDate = Cast('2015-05-31' as datetime)
If all you are trying to do is compare a Sql Date, then just use an agnostic format like '20150531' or easier to read '2015-05-31'. No need for casts or convert at all, i.e.
WHERE ... AND ProductDate = '2015-05-31'
However, if ProductDate isn't a date, but one of the *DATETIME* data types, and you are looking to update any time on the same day, then I believe you are looking for something like:
Update StockInvoiceInfo
set Quantity = Quantity - 2
where
p_id = 5
AND CAST(ProductDate AS DATE) = '2015-05-31';
However, the performance will be lousy as the clause isn't likely to be SARGable. You're better off simply doing:
AND ProductDate >= '2015-05-31' AND ProductDate < '2015-06-01';
(Resist the temptation to use between, or hacks like ':23:59:59' as there will be data corner cases which will bite you)
use CAST('5-31-2015' as DATETIME)
with the above update statement you started convert but with incomplete syntax
here the convert syntax
Update StockInvoiceInfo
set Quantity = Quantity - 2
where p_id = 5
AND ProductDate = convert(datetime,Cast('31-5-2015' as varchar),103) ;

convert string date to date type in sql server 2012

In a school website, I want to enable the admin to filter students based on date range when they were born. Dates in my tblStudent are stored as strings, so I cannot use:
SELECT ts.Name from tblStudent ts WHERE ts.BirthDay>'1367/01/31' AND ts.BirthDay<'1377/01/31'
I have saved dates (Jalali Format) in database table tblStudent. I need to do comparison based on dates. So I need to convert date strings to date type in sql server. To this purpose I used:
SELECT convert(date,tblStudent.BirthDay) from tblStudent
However,It stops after 27 results with the following error
Msg 241, Level 16, State 1, Line 1
Conversion failed when converting date and/or time from character string.
I have the following date strings in my tblStudent table.

Is there a way to convert these string dates to date type and then compare them with some query? For example, such a query can be:
SELECT ts.Name from tblStudent ts where ts.BirthDay>'1375/05/31'
I think you can make them ints and compare them:
SELECT ts.Name
FROM tblStudent ts
WHERE CONVERT(INT,REPLACE(ts.BirthDay,'/','') > 13670131
AND CONVERT(INT,REPLACE(ts.BirthDay,'/','') < 13770131
Or for your second example:
SELECT ts.Name
FROM tblStudent ts
WHERE CONVERT(INT,REPLACE(ts.BirthDay,'/','') > 13750531
This would work because having the order Year-Month-Day will ensure that the int representation of a later time will be greater than the int representation of an earlier time.
I really do not know if this is the best idea, but it is an idea of how to do it. After all you would be using a conversion.
From C# you have a few options:
If your input is string:
var dateInt = Int32.Parse(dateString.Replace("/",""));
If your input is Date then:
var dateInt = Int32.Parse(dateValue.ToString("yyyyMMdd"));
You could also pass the string itself in the db and let the db do the work for you :
DECLARE #Date AS VARCHAR(10)
SET #Date = ...--This will be filled with the inputed string
DECLARE #DateINT AS INT
SET #DateINT = CONVERT(INT,REPLACE(#Date,"/",""))
