I wanted to update a column for multiple rows based on the below condition -
I want to update column AUUSRTX of file abhipsha/AUDUSERF only for those rows
WHERE AUDUSERF.AUUSRTP <> 'USR' and AUDUSERF.AUUSRTP <> 'usr'
and the value that needs to be updated have to come from usrprffil.uptext from usrprffil of the matching user id . User ids of both tables are as follows
usrprffil.upuprf = auduserf.auusrid
Can someone please help with a correct query for this requirement.
I wrote the below 3 queries but i am getting error as -"Result of SELECT more than one row" for 1st and 2nd query
query 1 -
update abhipsha/auduserf
set AUUSRTX = (
SELECT usrprffil.uptext
from usrprffil inner join
abhipsha/auduserf
on upuprf =auusrid WHERE AUDUSERF.AUUSRTP <> 'USR'
and auduserf.auusrtp <> 'usr' and auusrid = usrprffil.upuprf)
query 2 -
update abhipsha/auduserf set AUUSRTX =
(SELECT uptext fROM usrprffil inner
join abhipsha/auduserf
on usrprffil.UPUPRF = auduserf.AUUSRID
WHERE
usrprffil.UPUPRF in (
SELECT AUUSRID FROM abhipsha/auduserf
WHERE
AUUSRTP <> 'USR' and AUUSRTP <> 'usr'
)
)
for the 3rd query i am getting - null value error
query 3 -
update abhipsha/auduserf
set auduserf.AUUSRTX = (
select UPTEXT
from usrprffil
WHERE usrprffil.UPUPRF = auduserf.AUUSRID
and usrprffil.UPUPRF in
(SELECT AUUSRID FROM abhipsha/auduserf
WHERE AUUSRTP <> 'USR' and AUUSRTP <> 'usr')
and uptext <> ' ' and
uptext is not null )
Null values not allowed in column or variable AUUSRTX.
Try this:
update abhipsha/auduserf a
set AUUSRTX =
COALESCE
(
(
SELECT min(u.uptext)
from usrprffil u
WHERE a.auusrid = u.upuprf
)
, AUUSRTX
)
WHERE a.AUUSRTP NOT IN ('USR', 'usr')
Notes:
The min function is used to not return multiple rows from the sub-select.
If the sub-select returns no rows, the AUUSRTX column value remains as is.
You may adjust the logic above according to your needs, of course.
I need a query based on an exclusive Or statement for this I try using the case but I won't get a result in case of Null...
...
and b.[U_Periode] = CASE
when (b.U_Periode= #period) then #period
when (b.U_Periode is NULL ) then null
end
...
The Case that won't be catched is... if B.U_Status is null and b.U_Periode is null.
If the var Periode match the Value and the U_Status = 0 or 1
the only way getting this working for me was this:
...
and
ISNULL( b.[U_Status],'0') = CASE
when (b.U_Status= '1') then '1'
when (isnull( b.U_Status,'0')= '0') then '0'
end
and
ISNULL (b.[U_Periode],'01.01.1901') = CASE
when (b.U_Periode= #period) then #period
when (ISNULL (b.U_Periode,'01.01.1901') = '01.01.1901' ) then '01.01.1901'
end
are there any other better solutions for this?

Okay... here is my Problem
Table1
InsID ContractID
1 1
2 1
Table2
ID insid Period Status Count
1 1 null null 100
2 1 30.09.2015 1 500
3 2 null null 100
4 2 30.09.2015 1 500
Case '31.08.2015'
in total Value should be 200
in case of '30.09.2015'
the Value should be 1.000
XOR /OR will do the same in this case.
Value case '31.08.2015' = 200
value Case ' 30.09.2015 = 2200
So this is somesing like a subquery
left join (
[dbo].[Table2]b
inner join [dbo].[Table 3]K on k.DocEntry = b.DocEntry and CAST( k.U_CSetID as int) >0
)
on b.[U_InsID] in(select... but here I should have an if statement...
If there are results matching the Date join this
If not than join the result NULL is matching to periode...
Okay.. here is the complete query
the Table2 with the Date of 31.08.2015 should have one Record that include
B_STATUS = Null and B.Preiode = null and there is no available record with the U_Periode '31.08.2015' and a Staus ...
with a date of 30.09.2015
there is a Record matching U_Period = '30.09.2015' in this case the Record with U_Period=null should not effect the result...
Declare #period as varchar(20)= '31-08-2015 00:00:00'
declare #Customer as Varchar(15)='12345'
declare #Contract as varchar(30) = '123'
declare #test as varchar(1) = null
select SUM(cast(K.U_Count as decimal))as counter, K.U_CounterTyp
from [dbo].[Table1] a
left join (
[dbo].[Table2]b
inner join [dbo].[Table 3]K on k.DocEntry = b.DocEntry and CAST( k.U_CSetID as int) >0
)
on b.[U_InsID]=a.[insID] and b.[U_ObjectType]in ('5','1') and
ISNULL( b.[U_Status],'0') = CASE
when (b.U_Status= '1') then '1'
when (isnull( b.U_Status,'0')= '0') then '0'
end
and
ISNULL (b.[U_Periode],'01.01.1901') = CASE
when (b.U_Periode= #period) then #period
when (ISNULL (b.U_Periode,'01.01.1901') = '01.01.1901' ) then '01.01.1901'
end
where a.[customer] =#Customer and a.[Status]='A' and a.[U_ContrCount]='1'
and a.[manufSN] in(
select c.[ManufSN] from [dbo].[Table4] c
inner join [dbo].[OCTR]d on d.[ContractID] = c.[ContractID]
where c.[ManufSN]=a.[manufSN]
and d.[CstmrCode] = a.[customer] and d.[ContractID]=#Contract
)
group by K.U_CounterTyp
you must use the "^" operand, this is XOR operand in TSQL
expression ^ expression
the expression must return or 0 or 1...
stupid example:
WHERE (name like "stackoverflow") ^ (age > 10)
font: https://msdn.microsoft.com/en-us/library/ms190277(v=sql.105).aspx
Update for your check
WHERE (CONVERT(VARCHAR(10), a.[U_Periode], 104) = '30.08.2015') != (a.U_Periode IS NULL)
Olay here is my funktion that chek either a Date Result is there or not.
The only thing is, that the performance is not the best if I run hundreths of sentences ... foreach record (up to app. 1000) I need to query each subtable... and there are many many records in...
Anyway this is the function
CREATE FUNCTION fn_GetInsCounters(#InsId as Varchar(30), #Date as datetime)
returns datetime
as
begin
declare #count as int = 0
declare #Retruns as Datetime
set #count =
(
select count( b.Docentry)
from [dbo].[Table2]b
where b.U_Insid =#InsID
and b.U_Status <> '2'
and b.[U_ObjectType]in ('5','1')
and b.U_Periode=#Date
)
if(#count>0)
begin
set #Retruns = #date
end
else
begin
set #Retruns = '01.01.1901'
end
return #Retruns
end
if anyone gets a better idea???

I'm writing a query with some CASE expressions and it outputs helper-data columns which help me determine whether or not a specific action is required. I would like to know if I can somehow use the result of a subquery as the output without having to perform the same query twice (between WHEN (subquery) THEN and as the result after THEN)
The dummy code below describes what I'm after. Can this be done? I'm querying a MS2005 SQL database.
SELECT 'Hello StackOverflow'
,'Thanks for reading this question'
,CASE
WHEN
(
SELECT count(*)
FROM sometable
WHERE condition = 1
AND somethingelse = 'value'
) > 0 THEN
-- run the query again to get the number of rows
(
SELECT count(*)
FROM sometable
WHERE condition = 1
AND somethingelse = 'value'
)
ELSE 0
END
SELECT 'Hello StackOverflow'
,'Thanks for reading this question'
,CASE
WHEN
(
SELECT count(*)
FROM sometable
WHERE condition = 1
AND somethingelse = 'value'
) AS subqry_count > 0 THEN
-- use the subqry_count, which fails... "Incorrect syntax near the keyword 'AS'"
subqry_count
ELSE 0
END
Just use the subquery as the source you are selecting from:
SELECT 'Hello StackOverflow'
,'Thanks for reading this question'
,CASE subqry_count.Cnt
WHEN 0 THEN 0
ELSE subqry_count.Cnt
END
FROM ( SELECT count(*) AS Cnt
FROM sometable
WHERE condition = 1
AND somethingelse = 'value'
) subqry_count
As an aside, if you are just going to return 0 if the output from COUNT is 0, then you don't even need to use a CASE statement.
Can I do this:
With ZipCodeCTE as
{
select nvl(HH.GeoUSZip5 , **ZipCodeKeyLookUp**(HH.[CityName],HH.[StateName])) as TotalZipCode
from ODSDataArchive.archive.HHJob_Data_201202 HH
}
/* This Is a SELECT INTO statement that inserts
data into [Jobs].[dbo].[FactRPP]*/
SELECT [dbo].[FactJobsDaily].jobdid,
[dbo].[FactJobsDaily].DateKey,
[dbo].[FactJobsDaily].YearMonth,
[dbo].[FactJobsDaily].AccountKey,
[dbo].[FactJobsDaily].BridgeSocKey,
[dbo].[FactJobsDaily].HostSiteKey,
[dbo].[FactJobsDaily].JobClickedCount,
[dbo].[FactJobsDaily].JobResultsPageCount,
(select DZ.ZipCodeKey
from dimensions.dbo.DimZipCode DZ
where DZ.ZipCodeKey IN
(Select CAST(TotalZipCode AS INT)
from ZipCodeCTE))
INTO [Jobs].[dbo].[FactRPP]
from dbo.FactJobsDaily
inner join ODSDataArchive.archive.HHJob_Data_201202
on dbo.FactJobsDaily.JobDID = ODSDataArchive.archive.HHJob_Data_201202.DID
and dbo.FactJobsDaily.datekey = ODSDataArchive.archive.HHJob_Data_201202.datekey
inner join dimensions.dbo.Dimzipcode dzc
on ODSDataArchive.archive.HHJob_Data_201202.geoUSZip5 = dimensions.dbo.Dimzipcode.ZipCode
where [dbo].[FactJobsDaily].yearmonth= 201202
and [dbo].[FactJobsDaily].isactivekey = 1
-- and ODSDataArchive.archive.HHJob_Data_201202.geoUSZip5 <> ''
-- and ODSDataArchive.archive.HHJob_Data_201202.geoUSZip5 IS NOT NULL
and ODSDataArchive.archive.HHJob_Data_201202.status = 0
and ODSDataArchive.archive.HHJob_Data_201202.CountryName = 'US'
order by [dbo].[FactJobsDaily].jobdid;
Because the CTE translates into a regular query the short answer is yes.
I have two variables, one is called PaidThisMonth, and the other is called OwedPast. They are both results of some subqueries in SQL. How can I select the smaller of the two and return it as a value titled PaidForPast?
The MIN function works on columns, not variables.
SQL Server 2012 and 2014 supports IIF(cont,true,false) function. Thus for minimal selection you can use it like
SELECT IIF(first>second, second, first) the_minimal FROM table
While IIF is just a shorthand for writing CASE...WHEN...ELSE, it's easier to write.
The solutions using CASE, IIF, and UDF are adequate, but impractical when extending the problem to the general case using more than 2 comparison values. The generalized
solution in SQL Server 2008+ utilizes a strange application of the VALUES clause:
SELECT
PaidForPast=(SELECT MIN(x) FROM (VALUES (PaidThisMonth),(OwedPast)) AS value(x))

http://sqlblog.com/blogs/jamie_thomson/archive/2012/01/20/use-values-clause-to-get-the-maximum-value-from-some-columns-sql-server-t-sql.aspx
Use Case:
Select Case When #PaidThisMonth < #OwedPast
Then #PaidThisMonth Else #OwedPast End PaidForPast
As Inline table valued UDF
CREATE FUNCTION Minimum
(#Param1 Integer, #Param2 Integer)
Returns Table As
Return(Select Case When #Param1 < #Param2
Then #Param1 Else #Param2 End MinValue)
Usage:
Select MinValue as PaidforPast
From dbo.Minimum(#PaidThisMonth, #OwedPast)
ADDENDUM:
This is probably best for when addressing only two possible values, if there are more than two, consider Craig's answer using Values clause.
For SQL Server 2022+ (or MySQL or PostgreSQL 9.3+), a better way is to use the LEAST and GREATEST functions.
SELECT GREATEST(A.date0, B.date0) AS date0,
LEAST(A.date1, B.date1, B.date2) AS date1
FROM A, B
WHERE B.x = A.x
With:
GREATEST(value [, ...]) : Returns the largest (maximum-valued) argument from values provided
LEAST(value [, ...]) Returns the smallest (minimum-valued) argument from values provided

I just had a situation where I had to find the max of 4 complex selects within an update.
With this approach you can have as many as you like!
You can also replace the numbers with aditional selects
select max(x)
from (
select 1 as 'x' union
select 4 as 'x' union
select 3 as 'x' union
select 2 as 'x'
) a
More complex usage
#answer = select Max(x)
from (
select #NumberA as 'x' union
select #NumberB as 'x' union
select #NumberC as 'x' union
select (
Select Max(score) from TopScores
) as 'x'
) a
I'm sure a UDF has better performance.
Here is a trick if you want to calculate maximum(field, 0):
SELECT (ABS(field) + field)/2 FROM Table
returns 0 if field is negative, else, return field.
Use a CASE statement.
Example B in this page should be close to what you're trying to do:
http://msdn.microsoft.com/en-us/library/ms181765.aspx
Here's the code from the page:
USE AdventureWorks;
GO
SELECT ProductNumber, Name, 'Price Range' =
CASE
WHEN ListPrice = 0 THEN 'Mfg item - not for resale'
WHEN ListPrice < 50 THEN 'Under $50'
WHEN ListPrice >= 50 and ListPrice < 250 THEN 'Under $250'
WHEN ListPrice >= 250 and ListPrice < 1000 THEN 'Under $1000'
ELSE 'Over $1000'
END
FROM Production.Product
ORDER BY ProductNumber ;
GO
This works for up to 5 dates and handles nulls. Just couldn't get it to work as an Inline function.
CREATE FUNCTION dbo.MinDate(#Date1 datetime = Null,
#Date2 datetime = Null,
#Date3 datetime = Null,
#Date4 datetime = Null,
#Date5 datetime = Null)
RETURNS Datetime AS
BEGIN
--USAGE select dbo.MinDate('20120405',null,null,'20110305',null)
DECLARE #Output datetime;
WITH Datelist_CTE(DT)
AS (
SELECT #Date1 AS DT WHERE #Date1 is not NULL UNION
SELECT #Date2 AS DT WHERE #Date2 is not NULL UNION
SELECT #Date3 AS DT WHERE #Date3 is not NULL UNION
SELECT #Date4 AS DT WHERE #Date4 is not NULL UNION
SELECT #Date5 AS DT WHERE #Date5 is not NULL
)
Select #Output=Min(DT) FROM Datelist_CTE;
RETURN #Output;
END;
Building on the brilliant logic / code from mathematix and scottyc, I submit:
DECLARE #a INT, #b INT, #c INT = 0;
WHILE #c < 100
BEGIN
SET #c += 1;
SET #a = ROUND(RAND()*100,0)-50;
SET #b = ROUND(RAND()*100,0)-50;
SELECT #a AS a, #b AS b,
#a - ( ABS(#a-#b) + (#a-#b) ) / 2 AS MINab,
#a + ( ABS(#b-#a) + (#b-#a) ) / 2 AS MAXab,
CASE WHEN (#a <= #b AND #a = #a - ( ABS(#a-#b) + (#a-#b) ) / 2)
OR (#a >= #b AND #a = #a + ( ABS(#b-#a) + (#b-#a) ) / 2)
THEN 'Success' ELSE 'Failure' END AS Status;
END;
Although the jump from scottyc's MIN function to the MAX function should have been obvious to me, it wasn't, so I've solved for it and included it here: SELECT #a + ( ABS(#b-#a) + (#b-#a) ) / 2. The randomly generated numbers, while not proof, should at least convince skeptics that both formulae are correct.
Use a temp table to insert the range of values, then select the min/max of the temp table from within a stored procedure or UDF. This is a basic construct, so feel free to revise as needed.
For example:
CREATE PROCEDURE GetMinSpeed() AS
BEGIN
CREATE TABLE #speed (Driver NVARCHAR(10), SPEED INT);
'
' Insert any number of data you need to sort and pull from
'
INSERT INTO #speed (N'Petty', 165)
INSERT INTO #speed (N'Earnhardt', 172)
INSERT INTO #speed (N'Patrick', 174)
SELECT MIN(SPEED) FROM #speed
DROP TABLE #speed
END
Select MIN(T.V) FROM (Select 1 as V UNION Select 2 as V) T
SELECT (WHEN first > second THEN second ELSE first END) the_minimal FROM table
