Can someone please advise on the below? I have a number of fields which I would like to use and combine these to get the data in one column. I am using the following case statement but am not getting the results I expect.
CASE
WHEN m.u_hearing = 1 THEN 'Hearing'
WHEN m.u_learning_reading_diff = 1 THEN 'Learning or reading Difficulty'
WHEN m.u_long_term_ill = 1 THEN 'Long Term Illness'
WHEN m.u_mental_illness = 1 THEN 'Mental Illness'
WHEN m.u_mobility = 1 THEN 'Mobility'
WHEN m.u_physical_coordination = 1 THEN 'Physical Co-ordination'
WHEN m.u_physical_dis = 1 THEN 'Physical Disability'
WHEN m.u_red_physical_cap = 1 THEN 'Reduced_physical_capacity'
WHEN m.u_speech = 1 THEN 'Speech'
WHEN m.u_vision = 1 THEN 'Vision'
WHEN m.u_other_dis = 1 THEN 'Other_Disability'
WHEN (m.u_hearing = 1 AND (m.u_learning_reading_diff = 1 OR (m.u_speech = 1))) THEN 'Multiple'
It is the last statement that is not giving the result I would like as if there are multiple fields with Yes then I would like multiple returned but it seems it is picking the first case.
Put the "hardest" condition first
case WHEN m.u_hearing = 1 AND (m.u_learning_reading_diff = 1 OR m.u_speech = 1) THEN 'Multiple'
WHEN m.u_hearing = 1 THEN 'Hearing' ...
Because a case stops at the first condition that is true
When using CASE statements, they will function in the order you have specified.
So if m.u_Hearing = 1 then it will stop at the first line and not reach the bottom one.
This will work for what you require, however list it in the order you prefer.
CASE
WHEN (m.u_hearing = 1 AND (m.u_learning_reading_diff = 1 OR (m.u_speech = 1))) THEN 'Multiple'
WHEN m.u_hearing = 1 THEN 'Hearing'
WHEN m.u_learning_reading_diff = 1 THEN 'Learning or reading Difficulty'
WHEN m.u_long_term_ill = 1 THEN 'Long Term Illness'
WHEN m.u_mental_illness = 1 THEN 'Mental Illness'
WHEN m.u_mobility = 1 THEN 'Mobility'
WHEN m.u_physical_coordination = 1 THEN 'Physical Co-ordination'
WHEN m.u_physical_dis = 1 THEN 'Physical Disability'
WHEN m.u_red_physical_cap = 1 THEN 'Reduced_physical_capacity'
WHEN m.u_speech = 1 THEN 'Speech'
WHEN m.u_vision = 1 THEN 'Vision'
WHEN m.u_other_dis = 1 THEN 'Other_Disability'
From what I know you cannot use your first statement again in another "when" like your
WHEN m.u_hearing = 1 THEN 'Hearing'
Above condition try to use else if it is working and feasible for you in end.
Else 'Multiple'

SELECT TOP 1
CostValue
FROM
[~client_table~].[dbo].[CostRules] AS CostRule
WHERE
(CASE
WHEN DATALENGTH(CostRule.ModelName) = 0
THEN
CostRule.Type = 1
AND CostRule.Manufacturer = Printer.ManufacturerId
AND CostRule.ColorType = 1
ELSE
CostRule.Type = 2
AND CostRule.ModelName = Printer.ModelName
AND CostRule.ColorType = 1
END
)
) AS MonoCost
I want to define my where statement depending on the datalength of CostRule.ModelName. But i got an error: Incorrect syntax near '='. in CostRule.Type = 1 and i got a error in the ELSE statement.
Must be like this:
...
WHERE
(DATALENGTH(CostRule.ModelName) = 0
AND CostRule.Type = 1
AND CostRule.Manufacturer = Printer.ManufacturerId
AND CostRule.ColorType = 1)
OR
(DATALENGTH(CostRule.ModelName) != 0
AND CostRule.Type = 2
AND CostRule.ModelName = Printer.ModelName
AND CostRule.ColorType = 1)
The CASE-style from your query cannot work.
you can change your statement like this:
SELECT TOP 1
CostValue
FROM
[~client_table~].[dbo].[CostRules] AS CostRule
WHERE CostRule.ColorType=1
AND CostRule.Type=CASE WHEN DATALENGTH(CostRule.ModelName) = 0 THEN 1 ELSE 2 END
AND CostRule.Manufacturer=CASE WHEN DATALENGTH(CostRule.ModelName) = 0 THEN Printer.ManufacturerId ELSE Printer.ModelName END
You can't use a CASE statement to define where conditions like that. It will be easier to just use some boolean logic
SELECT *
FROM your_table
WHERE (DATALENGTH(CostRule.ModelName) = 0
AND CostRule.Type = 1
AND CostRule.Manufacturer = Printer.ManufacturerId
AND CostRule.ColorType = 1)
OR (DATALENGTH(CostRule.ModelName) != 0
AND CostRule.Type = 2
AND CostRule.ModelName = Printer.ModelName
AND CostRule.ColorType = 1)
There are some other things that could be removed (like CostRule.ColorType = 1 since it is the same in both branches) but I've left them in here to illustrate how to transform your CASE statement into a boolean logic set.
It looks like you would just need to change the WHERE statement:
It looks like you will just need to change your WHERE statement to use OR and remove the CASE Statement.
(SELECT TOP 1
CostValue
FROM
[~client_table~].[dbo].[CostRules] AS CostRule
WHERE
DATALENGTH(CostRule.ModelName) = 0
CostRule.Type = 1
AND CostRule.Manufacturer = Printer.ManufacturerId
AND CostRule.ColorType = 1
OR
DATALENGTH(CostRule.ModelName) <> 0
AND CostRule.Type = 2
AND CostRule.ModelName = Printer.ModelName
AND CostRule.ColorType = 1

I have this Where clause
Select * From Student_Info si
Inner Join Certifications cc
Inner Join Cert_Earned ce
Where si.grad_date = #grad_date
AND cc.org_no = #org_no
but I need an additional AND that should be ignored if it turns out the value is false, I will want ALL certificates
AND cc.industrial = CASE WHEN #industrial = 0 THEN Do Nothing
Else #industrial
This would normally be expressed as:
AND (#industrial = 0 OR ccc.industrial = #industrial)
It sounds like you just want to add a predicate that does an OR between two different conditions
AND (#industrial = 0 or ccc.industrial = #industrial)
You can do something like this with CASE functions:
AND 1 = (CASE WHEN #industrial = 0 THEN 1
ELSE CASE WHEN cc.industrial = #industrial THEN 1 END
END)
or if cc.industrial is not nullable, then maybe:
AND cc.industrial = CASE WHEN #industrial = 0 THEN cc.industrial
Else #industrial END
I get this error:
Incorrect syntax near '='.
Code:
WHERE
T.[ID] = -9769
AND TNS.Active = 1
AND CASE
WHEN T.[StatusID] IN (1,6)
THEN (T.[AuditUser_ID] = 2 AND TNX.Actor = 2)
END
WHERE
T.[ID] = -9769
AND TNS.Active = 1
AND 1 = CASE
WHEN T.[StatusID] IN (1,6)
and (T.[AuditUser_ID] = 2 AND TNX.Actor = 2) then 1 else 0
END
I have these two case statements and can not for the life of me figure out how to combine them to show in a MSSQL view. Any help would be great.
CASE WHEN [ordertype] = '2' THEN [CommissionAmt1] * - 1 ELSE [CommissionAmt1] END
and
CASE WHEN (is_member('Buyer') = 1 OR is_member('CustomerService') = 1) THEN 0 ELSE CommissionAmt1 END
Just adding the first case to wherever the CommissionAmt1 is referenced in the second statement.
CASE WHEN (is_member('Buyer') = 1 OR is_member('CustomerService') = 1) THEN
0
ELSE
CASE WHEN [ordertype] = '2' THEN
[CommissionAmt1] * - 1
ELSE
[CommissionAmt1]
END
END
Or going the other way. It was hard to understand which way the calculation needs to be performed. The only hint was []
CASE WHEN [ordertype] = '2' THEN
(
CASE WHEN (is_member('Buyer') = 1 OR is_member('CustomerService') = 1) THEN
0
ELSE
CommissionAmt1
END
) * - 1
ELSE
CASE WHEN (is_member('Buyer') = 1 OR is_member('CustomerService') = 1) THEN
0
ELSE
CommissionAmt1
END
END
Either way, you would be able to save some calculations by sub querying the dependent value.
SELECT
*,
ValueWithDependant=CASE WHEN (Dependant>0) THEN (SomeValue / Dependant) ELSE NULL END
FROM
(
SELECT
X,Y,Z,
Dependant=CASE WHEN SomeValue=1 THEN 1 ELSE 0 END
FROM

I've got this code here and you can see from my Pseudocode what I'm trying to accomplish
select *
from dbo.BenefitsForms
inner join Dependents on BenefitsForms.UserId = Dependents.BenefitsForm_UserId
inner join CoverageLevels on BenefitsForms.MedicalId = CoverageLevels.Id
where (BenefitsForms.MedicalId > 0 AND BenefitsForms.MedicalId < 13)
AND Dependents.IsSpouse = CASE when CoverageLevels.[Level] = 2 then 1
when CoverageLevels.[Level] = 3 then 0 end
when CoverageLevels.[Level] = 4 then [any, it doesnt matter] <--- my desire but it doesn't work.
What can I do to get the effect I desire in the brackets? If Coverage Level = 4 then I don't care what Dependents.IsSpouse is, I don't even need to sort by it anymore.
Assuming that isSpouse can only be 0 or 1... if CoverageLevels.Level is 4, then compare isSpouse to itself, which will always result in true:
AND Dependents.IsSpouse = CASE
when CoverageLevels.[Level] = 2 then 1
when CoverageLevels.[Level] = 3 then 0
when CoverageLevels.[Level] = 4 then Dependents.IsSpouse
END
Alternately, this can also be expressed without the CASE:
WHERE
BenefitsForms.MedicalId > 0
AND BenefitsForms.MedicalId < 13
AND (
(Dependents.IsSpouse = 1 AND CoverageLevels.[Level] = 2)
OR (Dependents.IsSpouse = 0 AND CoverageLevels.[Level] = 3)
OR CoverageLevels.[Level] = 4
)
