I am using SQL, IBM Data Studio, db2-400. I need help writing a case statement that looks for the length of a field and returns a blank if it is not equal to 14, I have tried many ways without success, below is my latest attempt.
CASE
WHEN LENGTH(TRIM(FFIUPCN) <> '14'
THEN ''
ELSE
FFIUPCN
END AS "UPC (if applicable)"
The error I get is that the token "<>" is not valid.
Main issue is that you are missing a )
CASE
WHEN LENGTH(TRIM(FFIUPCN)) <> 14
THEN ''
ELSE
FFIUPCN
END AS "UPC (if applicable)"
but you shouldn't be comparing a numeric, returned by length(), to a sring '14'. But Db2 is implicitly converting it.
For multiple conditions you can nest your case statements
Select
case when FIUPCN+FFIUPCN2 = 0
then case when FIUPCN >= value then FIUPCN + 1
else FIUPCN + 2 end
else
case when FIUPCN >= value
then case when FIUPCN <> ''
then FIUPCN + 3
else prvca1 end
else
case
when FIUPCN >= FIUPCN2 and FIUPCN3 <> 0 then FIUPCN + 4
when FIUPCN >= FIUPCNX and FIUPCNY <> 0 then FIUPCN + 5
else prvca1 end
end
end

It's giving me the error
001044 (42P13): SQL compilation error: error line 9 at position 9
At WHEN is_Double(Replace(VALUE,'"','')) = 1
The case statement is saying "when it can be parsed as a double/numeric do so, else use NULL"
Thus is snowflake this section:
,CASE
WHEN is_Double(Replace(VALUE,'"','')) = 1
THEN CAST(Replace(VALUE,'"','') AS NUMBER)
ELSE NULL
END AS VALUE
can use TRY_TO_DOUBLE which if it fails to parse as a float, will return null.
thus:
,TRY_TO_DOUBLE(Replace(VALUE,'"','')) as value
I have a parameter #Destinataire in SSRS that has a list of values plus an empty string
I've created a query that I set as available values, which gives me the drop down list
SELECT code_name FROM tableA UNION ALL SELECT ''
When running the reports with the empty string, I have no results
I tried to set the parameter as text box and it does not do anything too
Yet when running the sql query I'm using to run this report, things are fine as I have all my rows retrieved (see query below)

First question would be to know if there is way to setup the parameter without using my stupid trick.
Second question is why the query with parameter with an empty string does the trick and once you use SSRS, nothing.
Thanks in advance for your help
Update I tried to set the WHEN LEN(#Destinataire) > 0 with the #Destinataire = '' but no luck on that one.
Update 2 My aim now is to have a solution that will retrieve all the datas, in case the #Destinataire is equal to '' or NULL. However, thinking about it, this solution is equivalent to having all the values populated in #Destinataire. So one way or another, I would say.
Final update I've recreated everything from scratch and oh! magic, the grouping or the everything option worked as wish. I still don't know what was wrong but I'm fine with the results. Many thanks for your help and support.
looking at your query and where you pass #Destinataire you should be able to pass a null value according to the where clause and get the same effect as passing ''
CASE --WHEN CFE_EDI.CODE_INSEE IS NOT NULL AND CFE_EDI.CODE_INSEE !=''
--THEN CASE
WHEN #Destinataire != '' AND (#Destinataire) IS NOT NULL
THEN CASE WHEN CFE_EDI.CODE_INSEE = #Destinataire THEN 1 ELSE 0 END
ELSE CASE WHEN CFE_EDI.CODE_INSEE = PARTENAIRES.CODE_INSEE
AND cfe_edi.dathrmaj > #DateCmt AND cfe_edi.dathrmaj < #DateFin
AND CFE_EDI.GESTDEL = '1' THEN 1 ELSE 0 END
END = 1
I would try to just set that particular paramter to allow nulls in the ssrs report which can be found as a checkbox in your parameter settings window.
There is a hybrid option, where you can keep your visible parameter just as you have it, but then use a hidden cascaded parameter to reference in the query. So if you really are having trouble with formulating your query with blank or null values as a parameter, this will work around that. Here are the steps:
Create a new dataset.
A slight catch, you do need to make sure that the changing the selection always adds a new value to force a refresh of the cascaded parameter, but that's easy to do:
SELECT code_name FROM tableA WHERE #Destinataire='' OR #Destinataire=code_name
--Dummy value needed to force update of parameter value in some cases:
UNION SELECT 'zz' + #Destinataire AS code_name
Set up a new parameter, #MultiDestataire. Allow it to accept multiple values and use the new dataset as its available and default values. Set its visibility to Hidden.
Running the report before hiding the new parameter shows how it works:
Edit the query to use the new multivalue parameter in its WHERE clause.
From here on, this is just altering the query to use the IN statement, which should look like this:
CFE_EDI.CODE_INSEE IS NOT NULL AND CFE_EDI.CODE_INSEE != ''
AND CFE_EDI.CODE_INSEE IN (#MultiDestinataire)
...
Attempting this may end up being an intermediary step if you've got some other issue in the query that's responsible for unexpected results, as you should be able to test for an empty value there.
This is just my two cents, basically you have two options here.
Multivalue parameter Option
Define your parameter to allow multivalues, use the same dataset in Available values and Default values properties. So when your user doesn't select any value the parameter will be populated with all values. Otherwise your parameter will be populated only with values your users select.
In this case you will have to use IN operator since your parameter represent multiple values seleted or not by your user.
...
WHERE CFE_EDI.CODE_INSEE IN (#Destinataire)
...
When you use Default values property all drop down list values are selected by default and your report run without any filter being applied (at least if your user doesn't select any value or values).
Additional, I'd avoid use '' (blank), it is uninformative and your user might think it is some kind of error or your parameter was not populated properly.
Why use a single value parameters when you want to show data from more than one value (in your case all)?
Single value Option (No sense IMO)
In order to this works you have to set your parameter to Allow blank value ("") and Allow null value. Your query should look like this:
WHERE
CASE WHEN #Destinataire = '' OR #Destinataire is null THEN 1 ELSE 0 END = 1
OR
CFE_EDI.CODE_INSEE = #Destinataire
In your query I think it could be something like this:
WHERE CASE
WHEN #Restriction = 1 THEN
CASE
WHEN cfe_edi.etat IN( 'ENV', 'OUV' ) THEN 1
ELSE 0
END
WHEN #Restriction = 0 THEN
CASE
WHEN cfe_edi.etat NOT IN( 'ENV', 'OUV' ) THEN 1
ELSE 0
END
ELSE
CASE
WHEN cfe_edi.etat <> '' THEN 1
ELSE 0
END
END = 1
AND cfe_edi.code_insee IS NOT NULL
AND cfe_edi.code_insee != ''
AND ( CASE
--WHEN CFE_EDI.CODE_INSEE IS NOT NULL AND CFE_EDI.CODE_INSEE !=''
--THEN CASE
WHEN ( #Destinataire = ''
OR #Destinataire IS NULL )
AND cfe_edi.code_insee = partenaires.code_insee
AND cfe_edi.dathrmaj > #DateCmt
AND cfe_edi.dathrmaj < #DateFin
AND cfe_edi.gestdel = '1' THEN 1
ELSE 0
END = 1
OR cfe_edi.code_insee = #Destinataire )
Also consider this evaluation AND cfe_edi.code_insee = partenaires.code_insee, is it necessary even if your JOIN operator is forcing to meet the condition? INNER JOIN dbo.CFE_EDI ON PARTENAIRES.CODE_INSEE = CFE_EDI.CODE_INSEE
A third option could be use a hidden parameter to clean the null and '' option of the user to produce a parameter populated with all values. Try the options above before get involved with hidden/internal parameter approach.
Let me know if this helps.
I'm trying to do the following which involves a complex query;
1. First I try to select the column based on some logic
2. then based on the value of the selected column a value is selected
3. finally based on the previous value a logic is applied to get the final value
How can I have the result from 2 in the ELSE of the 3rd Case..Then statement ?

CASE
WHEN MDC.Network ='I' THEN INNBenefitID ELSE OONBenefitID
END
WHEN 'INNDWO' THEN CASE WHEN DWO.Description IS NOT NULL THEN DWO.Description ELSE MDC.CostShareValue END
WHEN 'OONDWO' THEN CASE WHEN DWO.Description IS NOT NULL THEN DWO.Description ELSE MDC.CostShareValue END
ELSE isnull(dbo.fn_FormatText(MDC.CostShareValue, CostShareType),'''')
END
WHEN '0%' THEN 'Covered 100%'
WHEN '$0' THEN 'Covered 100%'
ELSE ????
END
Are you looking for something like that? :
declare #value varchar(255) = (
CASE
WHEN MDC.Network ='I' THEN INNBenefitID ELSE OONBenefitID
WHEN 'INNDWO' THEN CASE WHEN DWO.Description IS NOT NULL THEN DWO.Description ELSE MDC.CostShareValue
WHEN 'OONDWO' THEN CASE WHEN DWO.Description IS NOT NULL THEN DWO.Description ELSE MDC.CostShareValue
ELSE isnull(dbo.fn_FormatText(MDC.CostShareValue, CostShareType),'''')
END
)
CASE
WHEN '0%' THEN 'Covered 100%'
WHEN '$0' THEN 'Covered 100%'
ELSE #value
END
Really, really hard to do this right without a schema or sample data. In the future consider creating a SqlFiddle for us. But one approach you might consider is using a Common Table Expression (CTE) to define an intermediary structure which you then query.
;WITH theCTE AS (SELECT
CASE
CASE
WHEN MDC.Network ='I' THEN INNBenefitID ELSE OONBenefitID
END
WHEN 'INNDWO' THEN COALESCE(DWO.Description, MDC.CostShareValue)
WHEN 'OONDWO' THEN COALESCE(DWO.Description, MDC.CostShareValue)
ELSE COALESCE(dbo.fn_FormatText(MDC.CostShareValue, CostShareType), '')
END AS foo
FROM
bar
)
SELECT
CASE
WHEN foo IN ('0%', '$0') THEN 'Covered 100%'
ELSE '' -- Do something with foo --
END AS finalColumn
FROM
theCTE
Case stud.Status
when 'N'then 'NA'
end
How to add following condition before when statement above
IF #ID is not equal to 2. That is I want to assign 'NA' only when also the id <> 2 plus the above condition.
EDIT: Full Query
Case Stud.Status
when #ID = 2 AND Stud.Status = 'N' then 'To Be Submitted'
when 'N'then 'N/A'
else isnull(Stud.Status, '')
end
Like this:
CASE
WHEN #ID <> 2 AND stud.Status ='N' THEN 'NA'
END
This is the other form of the CASE expression.
Note that: The CASE expression has two forms:
The simple CASE expression compares an expression to a set of simple expressions to determine the result.
The searched CASE expression evaluates a set of Boolean expressions to determine the result.
Update: Try this instead:
'StudStatus' =
CASE
WHEN #ID = 5 AND Stud.Status = 'N' THEN 'To Be Submitted'
WHEN Stud.Status = 'N' THEN 'N/A'
ELSE ISNULL(Stud.Status, '')
END
try this
Case stud.Status
when 'N' and #id<>2 then 'NA'
end
if #ID <> 2
begin
Case stud.Status
when 'N'then 'NA'
end
end
I have the following:
set #SomeVariable = #AnotherVariable/isnull(#VariableEqualToZero,1) - 1
If #VariableEqualToZero is null it substitutes the 1. I need it to substitute 1 if #VariableEqualToZero = 0 as well. How do I do this?
If you're using SQL Server, you can probably use a NULLIF statement?
i.e. set the value to NULL if it's 0 then set it to 1 if it's NULL - should catch for both 0's and NULLs:
SET #SomeVariable = #AnotherVariable/ISNULL(NULLIF(#VariableEqualToZero,0),1) - 1
SET #SomeVariable = #AnotherVariable / COALESCE(
CASE
WHEN #VariableEqualToZero = 0 THEN 1
ELSE #VariableEqualToZero
END, 1) - 1
set #SomeVariable = #AnotherVariable /
(case when isnull(#VariableEqualToZero, 0) = 0 then 1 else
#VariableEqualToZero end) - 1
You use CASE
instead of
ISNULL(#VariableEqualToZero,1)
use
CASE WHEN #VariableEqualToZero IS NULL OR #VariableEqualToZero = 0 THEN 1 ELSE #VariableEqualToZero END
COALESCE and ISNULL are essentially just shortcuts for a CASE statement.
You can consult the help for the syntax of CASE.
