Using IF statement in Oracle SQL - oracle

I'm trying to use an IF ELSE statement in a sql query because I want to sum the units per district based on their package size per each PLN #. Can I do this? Here is my attempt, which does not work:
SELECT district_nbr,PLN_NBR, SUM(A.LO_IOH_UNITS) AS TOTAL_UNITS, SUM (A.LO_IOH_EXT_COST_DLRS) AS TOTAL_DOLLARS
FROM FCT_LOIOH_DAY_STR_PLN A, DIM_PROD_PLN B, DIM_LOCATION C
WHERE B.PLN_NBR IN(40000683181, 40000418723, 40000335776)
AND A.PROD_ID = B.PROD_ID
AND A.LOC_ID = C.LOC_ID
if PLN_NBR = '40000683181' then SUM(A.LO_IOH_UNITS)/25
else SUM(A.LO_IOH_UNITS)/60
GROUP BY district_nbr,PLN_NBR

SELECT district_nbr, PLN_NBR,
SUM(A.LO_IOH_UNITS) / (case when PLN_NBR = 40000683181 then 25 else 60 end) AS TOTAL_UNITS,
SUM (A.LO_IOH_EXT_COST_DLRS) AS TOTAL_DOLLARS
FROM FCT_LOIOH_DAY_STR_PLN A,
DIM_PROD_PLN B,
DIM_LOCATION C
WHERE B.PLN_NBR IN (40000683181, 40000418723, 40000335776)
AND A.PROD_ID = B.PROD_ID
AND A.LOC_ID = C.LOC_ID
GROUP BY district_nbr, PLN_NBR;

In Oracle SQL, you can use CASE WHEN ... ELSE for conditionals:
CASE WHEN PLN_NBR = '40000683181' THEN SUM(A.LO_IOH_UNITS) / 25
ELSE SUM)A.LO_IOH_UNITS) / 60
END
Such CASE WHEN ... statements go to the part where the other selected columns go:
SELECT
foo,
bar,
CASE ....
FROM
...

Using CASE in WHERE clause in Oracle 12c

I have a select statement like below :
SELECT * FROM
(SELECT d.value, d.line, d.language, l.pos_id, l.vehicle_id,l.vehicle_given
FROM Vehicle_value d,
vehicle_document l
WHERE d.gen_id = l.gen_id
AND d.pos_id = l.pos_id
AND d.gen_id = 1255) d1
LEFT OUTER JOIN
(SELECT d.value, d.line, d.language, l.pos_id, l.vehicle_id,l.vehicle_given
FROM TBB_GEN_Daten d,
TBB_GEN_Lesehilfe l
FROM Vehicle_value d,
vehicle_document l,
WHERE d.gen_id = l.gen_id
AND d.pos_id = l.pos_id
AND d.gen_id = 1254) d2
ON d1.value = d2.value
AND d1.pos_id = d2.pos_id
AND case when d1.vehicle_given = 'YES' then (d1.vehicle_id = d2.vehicle_id)
else end
AND d1.value is not null;
So I wanted to compare the d1.vehicle_id to d2.vehicle_id only when the d1.vehicle_given value is 'YES'. But the case statement i have used here is wrong and hence it doesnt work. is there any other to do this comparision ?
Bunch of typos in your code, but - when fixed, and with CASE being rewritten - query looks like this:
SELECT *
FROM (SELECT d.VALUE,
d.line,
d.language,
l.pos_id,
l.vehicle_id,
l.vehicle_given
FROM Vehicle_value d, vehicle_document l
WHERE d.gen_id = l.gen_id
AND d.pos_id = l.pos_id
AND d.gen_id = 1255) d1
LEFT OUTER JOIN (SELECT d.VALUE,
d.line,
d.language,
l.pos_id,
l.vehicle_id,
l.vehicle_given
FROM TBB_GEN_Daten d,
TBB_GEN_Lesehilfe l,
Vehicle_value d,
vehicle_document l
WHERE d.gen_id = l.gen_id
AND d.pos_id = l.pos_id
AND d.gen_id = 1254) d2
ON d1.VALUE = d2.VALUE
AND d1.pos_id = d2.pos_id
AND d1.vehicle_id =
CASE
WHEN d1.vehicle_given = 'YES' THEN d2.vehicle_id
ELSE d1.vehicle_id
END
AND d1.VALUE IS NOT NULL;
Use brackets and an OR condition for either the matching condition or when it is not YES:
AND ( d1.vehicle_given <> 'YES'
OR d1.vehicle_given IS NULL
OR d1.vehicle_id = d2.vehicle_id )
If you use a CASE expression such as:
AND d1.vehicle_id = CASE
WHEN d1.vehicle_given = 'YES'
THEN d2.vehicle_id
ELSE d1.vehicle_id
END
Then when the ELSE condition is matched you will effectively end up with AND d1.vehicle_id = d1.vehicle_id. This, naively, looks like it should be fine but if d1.vehicle_id is NULL then you will end up comparing NULL = NULL and the result is not truthy and the row will be excluded and that is not what you want.

GORM hangs with parameter

The below queries hangs exactly after 5 calls every time,

Can anyone help here

ORA-00904: "S"."AIR_TIME": invalid identifier

Why does this code show invalid identifier when sum is used in distance and air_time column?
When sum is not used this statement process successfully but using sum I get error? I need to use sum for this statement.

Query Optimization - Suggestions?

I am hoping someone can help me understand this XML Showplan for a long running query. This query comes from a Crystal Report developed by the software vendor that is very slow running, and I'm trying to convert it to an SSRS report while speeding the query up.

Thanks!
I removed the functions for returnDateTime and used the following instead:
-- In the FROM statement
Join Hemasphere_Dev.[dbo].CriticalDriveChanges Changes on (Changes.SourceDriveID = DM.DriveID And Changes.SourceShiftID = DSD.ShiftID And Changes.ChangeWhen Between '01/01/2015' And '01/15/2015')
--Hemasphere_Dev.[dbo].returnDateTime(year(Changes.ChangeWhen),month(Changes.ChangeWhen),day(Changes.ChangeWhen)) between '01/01/2015' And '01/15/2015')
-- In the WHERE statement
DM.FromDateTime Between '01/01/2015' And '01/15/2015'
Or Changes.PreviousDriveDate Between '01/01/2015' and '01/15/2015'
--(dbo.returnDateTime(year(DM.FromDateTime),month(DM.FromDateTime),day(DM.FromDateTime)) Between '01/01/2015' And '01/15/2015')
--Or (dbo.returnDateTime(year(Changes.previousdrivedate),month(Changes.previousdrivedate),day(Changes.previousdrivedate)) Between '01/01/2015' And '01/15/2015')
The query actually ran slower this way.

Problem in oracle query

Hai guys,
I've a query in which i need to interchange the values of two fields.
The query is as follows:
SELECT TO_DATE(A.G_LEDGER_DATE,'dd/mm/YYY')as G_LEDGER_DATE,C.ACC_MASTER_NAME,
A.G_LEDGER_REF_NO ,
NVL(CASE WHEN B.G_LEDGER_SECTION = 1 THEN
CASE WHEN
(SELECT COUNT(*)FROM SOSTRANS.ACC_GEN_LEDGER WHERE G_LEDGER_SECTION = B.G_LEDGER_SECTION AND G_LEDGER_ID = B.G_LEDGER_ID)> 1 THEN
B.G_LEDGER_VALUE ELSE A.G_LEDGER_VALUE END END,0) AS G_LEDGER_DR_VALUE,
NVL(CASE WHEN B.G_LEDGER_SECTION = -1 THEN
CASE WHEN
(SELECT COUNT(*) FROM SOSTRANS.ACC_GEN_LEDGER WHERE G_LEDGER_SECTION = B.G_LEDGER_SECTION AND G_LEDGER_ID = B.G_LEDGER_ID)> 1 THEN
B.G_LEDGER_VALUE ELSE A.G_LEDGER_VALUE END END,0) AS G_LEDGER_CR_VALUE,
B.G_LEDGER_SECTION,C.ACC_MASTER_ID,SUBSTR(A.G_LEDGER_REF_NO,0,3) AS Types,'Z' as OrderChar ,
CASE WHEN A.G_LEDGER_REMARK IS NULL THEN B.G_LEDGER_REMARK ELSE A.G_LEDGER_REMARK END AS Narration
FROM SOSTRANS.ACC_GEN_LEDGER A
LEFT OUTER JOIN SOSTRANS.ACC_GEN_LEDGER B ON A.G_LEDGER_ID = B.G_LEDGER_ID
LEFT OUTER JOIN SOSMASTER.ACC_ACCOUNT_MASTER C ON A.ACC_MASTER_ID = C.ACC_MASTER_ID WHERE A.G_LEDGER_CANCEL='N' AND
B.ACC_MASTER_ID = 'MSOS000001' AND
A.ACC_MASTER_ID <> 'MSOS000001' AND
A.G_LEDGER_SECTION <> B.G_LEDGER_SECTION AND
A.G_LEDGER_DATE >= '25/sep/2009' AND
A.G_LEDGER_DATE<='26/sep/2009'
ORDER BY OrderChar,G_LEDGER_DATE
Now i get the output as
... G_LEDGER_DR_VALUE G_LEDGER_CR_VALUE .....
... 2000 0 .....
... 3000 0 .....
... -1000 0 .....
I need to get the negetive value of the G_LEDGER_DR_VALUE side in G_LEDGER_CR_VALUE and if negetive value exists in G_LEDGER_CR_VALUE then it should be in the G_LEDGER_DR_VALUE field
Can anyone help me to solve this?
If I understood your question well, you select a value (that I will call g_ledger_value) that you want to appear in a different column depending on its sign.
This is how I would do it :
SELECT
CASE WHEN t.g_ledger_value>0 THEN t.g_ledger_value ELSE 0 END AS g_ledger_dr_value,
CASE WHEN t.g_ledger_value<0 THEN t.g_ledger_value ELSE 0 END AS g_ledger_cr_value
FROM
(SELECT g_ledger_value FROM mytable) t;
It sounds like a combination of SIGN() and CASE is what you need ...
CASE WHEN SIGN(G_LEDGER_DR_VALUE) = -1 then ...
ELSE ...
END
etc
SELECT G_LEDGER_DR_VALUE,
CASE WHEN G_LEDGER_DR_VALUE < 0
THEN G_LEDGER_CR_VALUE
ELSE G_LEDGER_DR_VALUE
END
FROM (...)
Is it that you mean? I suggest calculate values of CR___VALUE and DR_VALUE in subquery, and then in wrapping query make CASE which returns you correct value.
