Good day.. Im having a hard time in converting from ms access sql to sql server 2005 sql query.. and here's my code :
UPDATE Data SET
Data.Mean =([std1]+[std2]+[std3]/
IIf((3+(([std1]=0)+([std2]=0)+([std3]=0)))>0,
(3+(([std1]=0)+([std2]=0)+([std3]=0))),1)
WHERE Data.ID=125
I think the best way to convert this is by using CASE WHEN STATEMENT or any suggestions/alternatives you already know?
Thank you in advance!
Try this
UPDATE Data SET
Mean =([std1]+[std2]+[std3])/
case when abs([std1])+abs([std2])+abs([std3])=0 then 1 else
3 + case [std1] when 0 then -1 else 0 end
+ case [std2] when 0 then -1 else 0 end
+ case [std3] when 0 then -1 else 0 end
end
WHERE ID=125
UPDATE Data SET
Data.Mean =([std1]+[std2]+[std3]/
(CASE WHEN (3+(([std1]=0)+([std2]=0)+([std3]=0)))>0
THEN (3+(([std1]=0)+([std2]=0)+([std3]=0)))
ELSE 1
END))
WHERE Data.ID=125

I have a condition (in Business objects ) as below
=If([Actual ]=0;Sum([Applied] In ([Project];[ Name];[Number];[Sub ])))
which I need to convert it to CASE statement for my OBIEE
Below is the query I had tried but it doesn't work:
SELECT
CASE
WHEN F.ACTUAL_EQP_COST = 0
THEN SUM((F.HRS_APPLIED) IN(F.PROJECT,F.NAME,F.NUMBER,F.SUB))
ELSE 0
END
FROM F
Probably
select SUM(F.HRS_APPLIED)
from DTS_OSC_WIP_REP_CST_ANALYSIS_A F
where F.ACTUAL_EQP_COST = 0
group by F.PROJECT,F.WIP_ENTITY_NAME,F.OPERATION_NUMBER,F.OPERATION_SUB_SEQ
You can't use "in" inside a "then" statement.
I couldn't understand exactly but something in this direction might help:
select
CASE WHEN F.ACTUAL_EQP_COST = 0
THEN (SELECT SUM(F1.HRS_APPLIED)
FROM DTS_OSC_WIP_REP_CST_ANALYSIS_A F1
WHERE F1.column_name IN (F.PROJECT,F.WIP_ENTITY_NAME,F.OPERATION_NUMBER,F.OPERATION_SUB_SEQ))
ELSE 0 END
from DTS_OSC_WIP_REP_CST_ANALYSIS_A F
I tried searching around but couldn't find anything that would help me out.
I'm trying to do this in SQL:
DECLARE #onlyMM INT
SET #onlyMM = 1
SELECT *
FROM cdn.magnag
WHERE CASE #onlyMM
WHEN 1
THEN man_zrdtyp NOT IN (
1616
,2001
)
ELSE - 1
END
I have a problem with:
where case #onlyMM when 1 then man_zrdtyp not in (1616,2001) else -1 end
how to properly make a case for the operator not in?
I think you need to formulate the WHERE clause in a different way. You could use OR instead of case statement. Like this:
WHERE
(#onlyMM=1 AND man_zrdtyp not in (1616,2001))
OR #onlyMM<>1
You don't want to do this?
where (case when #onlyMM = 1 then man_zrdtyp else -1 end) not in (1616,2001)
I want to use case after where clause in SQL Server 2008; how can I use it like
select *
from MPR
where
case when #min >= 0
then MainComponent_Id = #mainc and SubComponent_Id = #subcomp
else MainComponent_Id = #mainc and SubComponent_Id = #subcomp and MinorComponent_Id = #minorc
end
end
I am using a stored procedure, and in my stored procedure if minorcomponent_id value is 0 then it will add 1 one else 2 one will work.
I had tried hard but its giving error in near case.
How to resolve it?
Thanks
You don't need to use a CASE statement. You can simplify logic as follows:
select
*
from
MPR
where
MainComponent_Id = #mainc AND SubComponent_Id = #subcomp
AND (#min >= 0 OR MinorComponent_Id = #minorc)
I am using Visual Studio 2008 and am in a report trying to create a query that has a WHERE statement that will return all records, if the #parameter = 0, otherwise I want the query to return only records that have the #paramete.
Here is the statement I envision, but can't seem to get correct:
WHERE (ADVISOR.staffPersonID = CASE WHEN #advisor = 0 THEN **'Do NOT
filter by staffpersonID'** ELSE #advisor END)
I have tried the following code which doesn't work:
CASE WHEN #advisor = 0 THEN ADVISOR.staffPersonID ELSE #advisor END
ADVISOR.staffPersonID is the field I would filter on, if the #parameter had a value other than 0. From what I've researched online, using the field itself as the THEN in the statement should work. It does, unless the table (advisor) has no records that match in it at all.
WHERE
(#advisor <> 0 AND ADVISOR.staffPersonID = #advisor)
OR
(#advisor = 0 )
try this:
WHERE ADVISOR.staffPersonID = #advisor OR #advisor = 0
WHERE ((ADVISOR.staffPersonID IS NULL AND #advisor = 0)
OR (ADVISOR.staffPersonID = CASE WHEN #advisor = 0 THEN
ADVISOR.staffPersonID
ELSE
#advisor END
))
I got the following SQL code (part of a select Statement):
Case
When HilfsTab2.Gruppe = 'HST' And Basis.Breite_FLA = Basis.Breite Then 0
Else Case When HilfsTab2.Gruppe = 'SA' Or HilfsTab2.Gruppe = 'HO / TB' Or
HilfsTab2.Gruppe = 'PR' Then 0 Else Case
When HilfsTab2.Gruppe Is Null Then -1 Else 1 End End
End As IsHST_Fluegel
Now, I run this over a table of several million entries. From my understanding, SQL checks the first case when for all rows, then the second for all entries and so on. This takes ages. Now I was thinking, there needs to be an easier way to do this.
I was thinking of a stored procedure / custom function that basically outputs -1, 0 or 1 depending on the entry.
Thanks in advance
For a possible speed improvement, do the NULL check first, the column comparison last and refactor to remove the nested CASE:
CASE WHEN HilfsTab2.Gruppe IS NULL
THEN -1
WHEN HilfsTab2.Gruppe IN ('SA', 'HO / TB', 'PR')
OR (HilfsTab2.Gruppe = 'HST' AND Basis.Breite_FLA = Basis.Breite)
THEN 0
ELSE 1
END AS IsHST_Fluegel
Your case could be simplified as:
Case
When HilfsTab2.Gruppe = 'HST' And Basis.Breite_FLA = Basis.Breite Then 0
When HilfsTab2.Gruppe in ('SA', 'HO / TB', 'PR') Then 0
When HilfsTab2.Gruppe Is Null Then -1
Else 1
End As IsHST_Fluegel
But this will not speed up your query. If you want to select millions of rows, it would take time anyway.
