I am having problem in part of my code anyway to do this
Only one expression can be specified in the select list when the subquery is not introduced with EXISTS. The update part is working but how to use insert into to calculate if a condition is not meant it will insert.
IF
/* CHECKLIST TO UPDATE*/
(NOT EXISTS
(SELECT *
FROM ENERGY.D_ENERGY_REFERENCE D_ENERGY_REFERENCE
,ENERGY.D_CHECK_LIST D_CHECK_LIST
WHERE D_ENERGY_REFERENCE.ID = D_CHECK_LIST.ID
AND D_ENERGY_REFERENCE.REFERENCE = 19051
)
)
BEGIN
INSERT INTO DB.D_ENERGY_REFERENCE(ID, REFERENCE_NO, REFERENCE,VALUE_INTEGER)
(SELECT ID,
(SELECT ISNULL(MAX(REFERENCE_NO), 0) + 1 FROM DB.D_ENERGY_REFERENCE),
19051, (SELECT D_CHECK_LIST.ID,
CASE
WHEN CAST(COUNT(CASE WHEN D_CHECK_LIST.EVALUATION NOT IN (0,1) THEN EVALUATION ELSE NULL END) AS FLOAT) = 0 THEN NULL
ELSE
(
CAST(COUNT(CASE WHEN D_CHECK_LIST.EVALUATION IN (2, 3, 50001, 50003, 50004, 50005, 50006, 50020, 50027, 50028) THEN EVALUATION ELSE NULL END) AS FLOAT)
/
CAST(COUNT(CASE WHEN D_CHECK_LIST.EVALUATION NOT IN (0,1) THEN EVALUATION ELSE NULL END) AS FLOAT)
) * 100
END FROM DB.D_CHECK_LIST
GROUP BY D_CHECK_LIST.ID)
FROM DB.D_ENERGY_REFERENCE D_ENERGY_REFERENCE
WHERE D_ENERGY_REFERENCE.ID = ID AND D_ENERGY_REFERENCE.REFERENCE = 19051
GROUP BY D_ENERGY_REFERENCE.ID
)
END
Can you please check this following part in the sub query of your script-
.......
19051,
(
SELECT
D_CHECK_LIST.ID, -- This is the column 1
CASE
WHEN -- Here you are generating column 2 in the sub query
......
)
Here you are selecting 2 column - one is "D_CHECK_LIST.ID" and other one is generation through CASE WHEN statement. I think you should SELECT any 1 column from those 2 column. If both are required, you can use separate Sub query for that.
The ERROR code "Only one expression can be specified in the select list when the subquery is not introduced with EXISTS" is self explanatory that you can not implement a Sub Query with more than 1 column selected unless the Sub Query is using inside EXISTS method.

I have a table named Bank that contains a Bank_Values column. I need a calculated Bank_Value_Unique column to shows whether each Bank_Value exists somewhere else in the table (i.e. whether its count is greater than 1).
I prepared this query, but it does not work. Could anyone help me with this and/or modify this query?
SELECT
CASE
WHEN NULLIF(LTRIM(RTRIM(Bank_Value)), '') =
(SELECT Bank_Value
FROM [Bank]
GROUP BY Bank_Value
HAVING COUNT(*) = 1)
THEN '0' ELSE '1'
END AS Bank_Key_Unique
FROM [Bank]
A windowed count should work:
SELECT
*,
CASE
COUNT(*) OVER (PARTITION BY Bank_Value)
WHEN 1 THEN 1 ELSE 0
END AS Bank_Value_Unique
FROM
Bank
;
It works also, but I found solution also:
select CASE WHEN NULLIF(LTRIM(RTRIM(Bank_Value)),'') =
(select Bank_Value
from Bank
group by Bank_Value
having (count(distinct Bank_Value) > 2 )) THEN '1' ELSE '0' END AS
Bank_Value_Uniquness
from Bank
It was missing "distinct" in having part.
I have a table with columns Recordnumber, Test, Value, Date and Complement. Recordnumber and test are the primary key.
I need compare values from TW01SS and TW01D1+TW01D2 with the same Recordnumber and depending on which value is bigger add it to Complement column. Any ideas?
Thank you
You can create two CTE's, one to get the SS count and the other the D1+D2 count then UPDATE the Complement column by the Recordnumber.
See WITH common_table_expression (Transact-SQL)
Specifies a temporary named result set, known as a common table
expression (CTE). This is derived from a simple query and defined
within the execution scope of a single SELECT, INSERT, UPDATE, DELETE
or MERGE statement. This clause can also be used in a CREATE VIEW
statement as part of its defining SELECT statement. A common table
expression can include references to itself. This is referred to as a
recursive common table expression.
;WITH
D1D2_Count
AS
-- Define D1+D2 Count CTE Query.
(
SELECT RecordNumber AS D1D2_ID,
SUM(Value) OVER(PARTITION BY RecordNumber) AS D1D2_Total
FROM TestA
WHERE Test LIKE '%D1' OR Test LIKE '%D2'
),
SS_Count
AS
-- Define SS Count CTE Query.
(
SELECT RecordNumber AS SS_ID,
SUM(Value) OVER(PARTITION BY RecordNumber) AS SS_Total
FROM TestA
WHERE Test LIKE '%SS'
)
UPDATE A
SET Complement =
CASE WHEN D1D2_Total > SS_Total
THEN D1D2_Total
ELSE SS_Total
END
FROM TestA AS A
LEFT JOIN D1D2_Count ON RecordNumber = D1D2_ID
LEFT JOIN SS_Count ON RecordNumber = SS_ID
See Fiddle.
Optionally, you can add a WHERE clause to the end of the UPDATE statement so that it'll only update the Complement that has the greater total
If D1+D2 > SS, UPDATE Only the D1+D2 rows
Otherwise, UPDATE Only the SS rows.
Like this:
WHERE Test LIKE
CASE WHEN D1D2_Total > SS_Total
THEN '%D1'
ELSE '%SS'
END
OR Test LIKE
CASE WHEN D1D2_Total > SS_Total
THEN '%D2'
ELSE '%SS'
END
select *, case when SS >= DX then SS else DX end
from T cross apply (values (
sum(case when Test = 'TW01SS1' then Value end)
over (partition by RecordNumber),
sum(case when Test like 'TW01D[12]' then Value end)
over (partition by RecordNumber))
) s(SS, DX);
You can use else coalesce(DX, SS) if null/missing tests are at play.
As an update:
update T
set Complement = (
select case when SS >= DX then SS else DX end
from T t2 cross apply (values (
sum(case when Test = 'TW01SS1' then Value end),
sum(case when Test like 'TW01D[12]' then Value end)
) s(SS, DX)
where t2.RecordNumber = T.RecordNumber
);
I want to add some calculation inside my case statement to dynamically create the contents of a new column but I get the error:
Column 'Test1.qrank' is invalid in the select list because it is not contained in either an aggregate function or the GROUP BY clause.
This is the code I'm working on
case
when test1.TotalType = 'Average' then Test2.avgscore
when test1.TotalType = 'PercentOfTot' then (cnt/SUM(test1.qrank))
else cnt
end as displayscore
I did try to group but it didn't work.
Any hints?
The error you posted can happen when you're using a clause in the GROUP BY statement without including it in the select.
Example
This one works!
SELECT t.device,
SUM(case when transits.direction = 1 then 1 else 0 end) ,
SUM(case when transits.direction = 0 then 1 else 0 end) from t1 t
where t.device in ('A','B') group by t.device
This one not (omitted t.device from the select)
SELECT
SUM(case when transits.direction = 1 then 1 else 0 end) ,
SUM(case when transits.direction = 0 then 1 else 0 end) from t1 t
where t.device in ('A','B') group by t.device
This will produce your error complaining that I'm grouping for something that is not included in the select
Please, provide all the query to get more support.
You could use a Common Table Expression to create the SUM first, join it to the table, and then use the WHEN to to get the value from the CTE or the original table as necessary.
WITH PercentageOfTotal (Id, Percentage)
AS
(
SELECT Id, (cnt / SUM(AreaId)) FROM dbo.MyTable GROUP BY Id
)
SELECT
CASE
WHEN o.TotalType = 'Average' THEN r.avgscore
WHEN o.TotalType = 'PercentOfTot' THEN pt.Percentage
ELSE o.cnt
END AS [displayscore]
FROM PercentageOfTotal pt
JOIN dbo.MyTable t ON pt.Id = t.Id
If you're using SQL Server 2005 or above, you can use the windowing function SUM() OVER ().
case
when test1.TotalType = 'Average' then Test2.avgscore
when test1.TotalType = 'PercentOfTot' then (cnt/SUM(test1.qrank) over ())
else cnt
end as displayscore
But it'll be better if you show your full query to get context of what you actually need.
HI Gurus,
I'm looking to replace an IN clause with exists, but despite reading other similar cases on here I've not been able to apply them to my dataset.
I am looking to add in a column to my main query which tells me if a fund is found within a separate list, and if it does then label it 'emergency' and if not then 'non-emergency'
The list is defined like so:
select
f.id
FROM _audit a
INNER JOIN _fund f ON a.article_id = f.id
WHERE a.entity_name = 'Fund'
AND a.Changes LIKE
'%finance_code2%OldValue>3%'
)
UNION
(
select
id AS fund_reference
FROM _fund
WHERE (finance_code2 LIKE '3%'
OR finance_code2 LIKE '9%')
AND finance_code2 IS NOT NULL
And so what I am looking for is essentially something like:
SELECT
...Main query here...
,CASE WHEN fund_id IN (list_details) THEN 'emergency' else 'non-emergency' end
I know that it would be more efficient to do something like
SELECT
...Main query here...
,SELECT CASE WHEN EXISTS
(SELECT fund_id FROM list_details WHERE fund_id IS NOT NULL) THEN 'emergency' else 'non-emergency' END
But every time I try it keeps returning false values (saying that funds are contained within the list when they are not)
In case it helps I'm using sql server 2005 and the main query is listed below, where the list_details result (id) is joined onto donation_fund_allocation on list_details.id = donation_fund_allocation.fund_id
As always any clue would be massively appreciated :)
Thanks!
Main query
SELECT
don.supporter_id AS contact_id
,don.id AS gift_id
,YEAR(don.date_received) AS calendar_year
,YEAR(don.date_received) - CASE WHEN MONTH(don.date_received) < 4 THEN 1 ELSE 0 END AS financial_year
,don.date_received AS date_received
,don.event_id AS event_id
,SUM(CASE WHEN don.gift_aid_status <> 4 THEN don.value_gross * ((dfa.percentage) / 100)
WHEN don.gift_aid_status = 4 AND don.value_net > don.value_gross
AND don.value_net <> 0 THEN don.value_net * ((dfa.percentage) / 100)
ELSE don.value_gross * ((dfa.percentage) / 100)
END
) AS donation_value
--**List details query to go in here**
FROM donation don WITH (nolock)
INNER JOIN donation_fund_allocation dfa WITH (nolock) ON dfa.donation_id = don.id
WHERE don.supporter_id IS NOT NULL
AND don.status = 4
AND don.value_gross <> 0
GROUP BY don.supporter_id
,don.id
,don.date_received
,don.event_id
You need to correlate the exists call with the outer query. As written you are just asking if there exist any rows in list_details where fund_id isn't null
So, what you actually want is
SELECT
...Main query here...
,SELECT CASE WHEN EXISTS
(SELECT 1 FROM list_details WHERE fund_id = outer.fund_id) THEN 'emergency' else 'non-emergency' END
Where outer is the table alias for where fund_id can be found in your main select
You could write a function which takes the fund_id and returns an appropriate string value of "emergency" or "non-emergency".
I have a sub query that returns one column, showing as GroupType, I then want to do a CASE function on this result within the main query, however I get an invalid column name when using the CASE statement.
Can i do this in SQL to do I have to refer to it by a different name
SELECT CASE
WHEN
(
SELECT column
FROM othertable
) = 1
THEN '1'
ELSE '2'
END
FROM mytable
To reuse the subquery result:
SELECT subvalue, CASE subvalue WHEN 1 THEN 1 ELSE 2 END
FROM (
SELECT (
SELECT column
FROM othertable
) AS subvalue
FROM mytable
) q
