I want to CONCAT between this on my SELECT statement in SQL Server.
All the columns are booleans.
The output will be like this if all of columns that are true
GGPNES
I tried to use this and it doesn't work
DECLARE #concat VARCHAR(40) ='';
SELECT
Smoke, Invoice,
Party, Summary,
MySelf, Export,
CASE
WHEN MyTable.Smoke = 1 OR MyTable.Invoice = 1
THEN #concat + 'GG'
WHEN MyTable.Party = 1
THEN #concat + 'P'
WHEN MyTable.Summary = 1
THEN #concat + 'N'
WHEN MyTable.MySelf = 1
THEN #concat + 'E'
WHEN MyTable.Export = 1
THEN #concat + 'S'
END
FROM
MyTable
I think that you want a concatenation of CASE expressions:
CASE WHEN Smoke = 1 OR Invoice = 1 THEN 'GG' ELSE '' END +
CASE WHEN Party = 1 THEN 'P' ELSE '' END +
CASE WHEN Summary = 1 THEN 'N' ELSE '' END +
CASE WHEN MySelf = 1 THEN 'E' ELSE '' END +
CASE WHEN Export = 1 THEN 'S' ELSE '' END

if i have a column in which ten digit values occurs like Column A = 11111000 so how to show this value in sql like (List,Add,Edit,Delete,Export) in sql.
there is a condition means if first position have 1 then it show List, If second Position have 1 it show Add, third position have 1 then Edit, fourth position have 1 then Delete, fifth position have 1 then Export.
If the value is a string, you can do:
select stuff( ((case when substring(a, 1, 1) = 1 then ',List' else '' end) +
(case when substring(a, 2, 1) = 1 then ',Add' else '' end) +
. . .
), 1, 1, '')
The logic is similar for bitwise operators:
select stuff( ((case when a & 2^9 then ',List' else '' end) +
(case when 2 & 2^8 then ',Add' else '' end) +
. . .
), 1, 1, '')
Maybe Substring function can help you to identify these values
select
id, ColumnA,
case when substring(ColumnA,1,1) = '1' then 'X' end as List,
case when substring(ColumnA,2,1) = '1' then 'X' end as [Add],
case when substring(ColumnA,3,1) = '1' then 'X' end as Edit,
case when substring(ColumnA,4,1) = '1' then 'X' end as [Delete],
case when substring(ColumnA,5,1) = '1' then 'X' end as [Export]
from Table1
I update the query according to comment
select
id, ColumnA,
stuff(
case when substring(ColumnA,1,1) = '1' then ',List' else '' end +
case when substring(ColumnA,2,1) = '1' then ',Add' else '' end +
case when substring(ColumnA,3,1) = '1' then ',Edit' else '' end +
case when substring(ColumnA,4,1) = '1' then ',Delete' else '' end +
case when substring(ColumnA,5,1) = '1' then ',Export' else '' end
,1,1,''
)
from Table1
When I execute this SQL code:
select id, opis, vidrabota, tipprov, hitnost, valuta, drzava, zbirnaprov, tip_zbirprov, kanal
from dev_1450autoebanktip
where opis is null or Opis like case when isnull('','') = '' then Opis else '%' + '' + '%' end
and VidRabota = case when isnull('','') = '' then VidRabota else '' end
and TipProv = case when isnull(0,0) = 0 then TipProv else 0 end
and Valuta = case when isnull('','') = '' then Valuta else '' end
and drzava is null or Drzava = case when isnull('','') = '' then Drzava else '' end
I get this set of results:
But when I add one more condition (last row):
select id, opis, vidrabota, tipprov, hitnost, valuta, drzava, zbirnaprov, tip_zbirprov, kanal
from dev_1450autoebanktip
where opis is null or Opis like case when isnull('','') = '' then Opis else '%' + '' + '%' end
and VidRabota = case when isnull('','') = '' then VidRabota else '' end
and TipProv = case when isnull(0,0) = 0 then TipProv else 0 end
and Valuta = case when isnull('','') = '' then Valuta else '' end
and drzava is null or Drzava = case when isnull('','') = '' then Drzava else '' end
and KANAL = case when isnull(0,0) = 0 then KANAL else 0 end
I am losing one row in the result. What is causing this change?
Kanal is NULL in the last row.
and KANAL = case when isnull(0,0) = 0 then KANAL else 0 end
boils down to
and KANAL = KANAL
But this is not true for NULL, because NULL is the unknown value. When comparing null with null the result is neither true nor false, but unknown. Thus the added criteria dismisses the last record.
There is one thing I'd like to add: Use parentheses when mixing AND and OR. For instance
a = b or a = c and d = e
means
a = b or (a = c and d = e)
because AND has precedence over OR and you may want the expression to mean
(a = b or a = c) and d = e
Use parentheses in order to avoid any mistakes.
I am working on this stored proc which check to see which BIT fields are true and depending on it assigns a text to it using alias name. I want to be able to combine these alias values (string) and have it comma delimited to I can display it on my SSRS report.
Below is part of my stored proc.
,CASE
WHEN sr.[ReservationAlreadySentAttached] = 1 THEN 'Reservation Already Sent'
END AS ReservationAttached
,CASE
WHEN sr.[HPOfficeAttached] = 1 THEN 'H&P Office'
END AS HPOfficeAttached
WHEN sr.[NotesAttached] = 1 THEN 'Notes'
END AS NotesAttached
,CASE
WHEN sr.[OpPermitAttached] = 1 THEN 'Op Permit'
END AS OpPermitAttached
,CASE
WHEN sr.[TestResultsAttached] = 1 THEN 'Test Results'
END AS TestResultsAttached
,CASE
WHEN sr.[ConsultationReportsAttached] = 1 THEN 'Consultation Reports'
END AS ConsultationReportsAttached
,CASE
WHEN sr.[OtherAttached] = 1 THEN 'Other'
END AS OtherAttached
so lets say in case where only NotesAttached and ReservationAlreadySentAttached were only true ones then I want the end result to come out as Notes, Reservation Already Sent.
How do i concatenate these aliases ?
Another option is to build your string and then just remove the leading comma with STUFF()
Example (abbreviated)
Declare #YourTable table (ReservationAlreadySentAttached bit,HPOfficeAttached bit,NotesAttached bit)
Insert Into #YourTable values
(1,0,1)
Select NewValue = stuff(
case when ReservationAlreadySentAttached = 1 then ', Reservation Already Sent' else '' end
+case when HPOfficeAttached = 1 then ', H&P Office' else '' end
+case when NotesAttached = 1 then ', Notes' else '' end
,1,2,'')
From #YourTable
Returns
NewValue
Reservation Already Sent, Notes
EDIT - Just the Expression
NewValue = stuff(
case when sr.[ReservationAlreadySentAttached] = 1 then ', Reservation Already Sent' else '' end
+case when sr.[HPOfficeAttached] = 1 then ', H&P Office' else '' end
+case when sr.[NotesAttached] = 1 then ', Notes' else '' end
,1,2,'')
Not the prettiest solution...
RIGHT((CASE
WHEN sr.[ReservationAlreadySentAttached] = 1
THEN ',Reservation Already Sent'
END + CASE
WHEN sr.[HPOfficeAttached] = 1
THEN ',H&P Office'
END + CASE
WHEN sr.[NotesAttached] = 1
THEN ',Notes'
END + CASE
WHEN sr.[OpPermitAttached] = 1
THEN ',Op Permit'
END + CASE
WHEN sr.[TestResultsAttached] = 1
THEN ',Test Results'
END + CASE
WHEN sr.[ConsultationReportsAttached] = 1
THEN ',Consultation Reports'
END + CASE
WHEN sr.[OtherAttached] = 1
THEN ',Other'
END)
,LEN(CASE
WHEN sr.[ReservationAlreadySentAttached] = 1
THEN ',Reservation Already Sent'
END + CASE
WHEN sr.[HPOfficeAttached] = 1
THEN ',H&P Office'
END + CASE
WHEN sr.[NotesAttached] = 1
THEN ',Notes'
END + CASE
WHEN sr.[OpPermitAttached] = 1
THEN ',Op Permit'
END + CASE
WHEN sr.[TestResultsAttached] = 1
THEN ',Test Results'
END + CASE
WHEN sr.[ConsultationReportsAttached] = 1
THEN ',Consultation Reports'
END + CASE
WHEN sr.[OtherAttached] = 1
THEN ',Other'
END) - 1 )
Edit: You may have to take into consideration when NONE of them are 1 so you don't get Invalid length parameter passed to the right function.
CASE
WHEN sr.[ReservationAlreadySentAttached] = 1 THEN ', Reservation Already Sent' ELSE ''
END
+ CASE
WHEN sr.[HPOfficeAttached] = 1 THEN ', H&P Office' ELSE ''
END
+ CASE etc...
And wrap this in some function to remove the first comma + space.
I have a table with the 'ContentSubCategory' name.its fields are like below:
Id int
FaName nvarchar(50)
IsSpecial bit
IsPerishable bit
IsDanger bit
now I Want a query that shows list of content names and the attributes that are set to True.
for example:
Row ContentInfo
------------------------------------
1 animal - IsSpecial
2 Human Body - IsSpecial,IsPerishable
3 Danger Goods - IsSpecial,IsDanger
how can I do that?
select cast(FaName as varchar)+' - '+cast(
case when IsSpecial = 1 then 'IsSpecial,' else '' as varchar)+cast(
case when IsPerishable = 1 then 'IsPerishable,' else '' as varchar)+cast(
case when IsDanger = 1 then 'IsDanger' else '' as varchar)
from your_table
Try this and adjust to your own like.
You can also use STUFF():
SELECT
FaName
,ISNULL(
NULLIF(
STUFF(
CASE WHEN IsSpecial = 1 THEN ', IsSpecial' ELSE '' END
+ CASE WHEN IsPerishable =1 THEN ', IsPerishable' ELSE '' END
+ CASE WHEN IsDanger = 1 THEN ', IsDanger' ELSE '' END
, 1, 2, '')
,'')
, 'Unknown')
As Class
FROM TableName
After some previous help on how to approach a problem I am having with some legacy code, it seems like the best approach for my issue is to concatenate case statements to return a value I can parse out in PHP.

Well, this is embarrassing.
When I was making my changes to the stored procedure, I had inadvertently placed a call to the same procedure at the bottom. So I was recursively calling the same procedure over and over again. DOH.
