Case Statement with Group By

Hello,
I am trying to build a query that returns the 3 months of a quarter. Below are the two case statements that I am trying to use. I am getting a "Not a group by expression" in the first case statement, and a "nota a single-group group function in the second. Any help with this would be appreciated.
Thanks, sck10

You are getting the "Not a group by expression" error because you are not using in aggregate functions in your select statement. (You are using the aggregate function SUM in the second query)
The "not a a single-group group function" means you are returning multiple rows of a data when it only expects one.

/If the condition involves a query, then you may have to select the results into a variable first, and then use the variable in the CASE statement.

Case function with group by

Hi,
I am having a scenario like :
Column 1: BrokerList(dimension1)
Column 2 : Broker(dimension2)
Column 3 : Metric value(measure)
so i am having a case when (dimension 3) Custodian = 'ss' then sum(metirc) group by dimension1,dimension2 but the result value is not matching
BrokerList
Broker
Metric
a1
a
10
b
20
c
30
a1 :total
60
a2
a
50
c
60
d
10
a2:total
120
Grand total
180
Here the metric is based on other case condition.. so the total value is not matching.. Is there any other way to do a case function with group by funtions. Please advise.
regards,
Guru

Use filter on metric by ss value and then go for group by from Criteria
something like
sum(FILTER(metric USING (Custodian = 'ss')) by dimension1,dimension2)

Case statement with having null gives default result

Hello,
When we write a case statement with a not equal condition <> on a column and if that columns has null value the it gives the else value.
eg
Select Column_Name, Case when Column_Name <>Condition then 0 else 1 end as case_test from Table_Name.
Ideally null is not equal to the condition so the case should return 0 but it returns 1. Can anyone tell me why?

In addition to the other posts:
NULL is an unknown value, when you say
col <> 1
and col is NULL, we don't know whether col is 1 or something else. Thus the condition evaluates to UNKNOWN. How UNKNOWN is handled depends on the context. In WHEN clauses as well as the IF statments, the effect that the code bracketed by IF/WHEN is not
entered. That is, UNKNOWN and FALSE yields the same result. In CHECK constraints, it's the other way round. If you have
CHECK (WHEN col <> 0)
rows where col is NULL are accepted.
When you work with SQL, no matter the database product, it's imperative to master three-valued logic, because it comes up all the time.
As I said, NULL is the unknown value. In practice, NULL has a distinct interpreation depending on the database column. For instance, NULL in a column called EndDate, usually means that the period (or whatever it is) is still open. So often when you work
with NULL values you use isnull to replace it with some value that fits the context, and finding that value takes some consideration. Blindly doing isnull(col, '') can lead to serious bugs, particularly if col is not a string column.

Hi,
So, you don't want to ignore the whole row when stat != 'E' (that would ignore the only row with id='3'). Putting the condition 'stat = 'E' in the WHERE clause sill ignore the row, so that's not what you want.
You just want to ignore the term column. Put the same condition in a CASE expression that only contols that column.
Here's one way:
SELECT       id
,       MIN ( CASE
                 WHEN stat = 'E'
              THEN     term
             END
           )          AS min_e_term
FROM      dan_gr2
GROUP BY id
ORDER BY id

Case Statement and Group By issues

Hi this is my initial query which works perfectly:

You would need DECLINE in the group by clause of your inner query.
Additionally you would need to change TOTAL_COST to SUM(TOTAL_COST) in where case statement.
But then you would retrieve one row for each value of DECLINE in this query.
You also could use this:
(I don't know if it will meet your requirements)
SELECT ff.cla_case_no,
                 cost_before_decision,
                 cost_of_claim,
                 ff.decline,
                 decline_description
FROM fraud_nov_14_final ff,
                 (SELECT   cla_case_no,
                           SUM (decode(decline,1,total_cost_adj_old+decline_estimate,
                                               2,total_cost_adj_old+decline_estimate,
                                               total_cost)) cost_before_decision
                                FROM reporting.ci_final@test
                  GROUP BY cla_case_no) z
WHERE ff.cla_case_no = z.cla_case_no;(untested code, because I don't have your tables)

Help With A Case Statement With Multiple Variables

I apologize if this is the incorrect Forum for this type of question, but it was the closest one that I could find. I'm pretty new with SQL and am stuck on this issue. I have roughly 26 dates that I need to compare to one another. Each date is tied to a step code. I also have a Stop value that is tied directly to the "max date" of the step codes. So, I need to compare 30 dates against one another to 1st - ID the max date; 2nd - ID if the Stop value is correct; 3rd - if the stop value is incorrect, identify what the correct value would be.
At first, this seemed like it wouldn't be that hard. I wrote a query that found the max date for each step code. Then I realized that multiple step codes could have the same date. So, I tried using this case statement, but I did not get the expected results. Is there a more efficient way of getting what I need? This code seems like it's not necessary and probably the source of my issue.

ELSE 'UH OH'
END AS "CHANGE FC STOP TO"
Any assistance is appreciated!

I think Igor pointed out a working solution before.
Applying it at your examples (you missed the operator after STOP_CODE, I assume it =):
CASE
WHEN FS25 = GREATEST(FS25, FS24, FS23) AND STOP_CODE = '9' THEN '9'
ELSE 'UH OH'
END AS 'CHANGE STOP CODE TO'
{code}
Be careful at the second example. You are checking:
{code:sql}
FS25 > FS24 OR FS25 IS NOT NULL AND FS24 IS NULL AND FS25 > FS23
OR
FS25 IS NOT NULL AND FS23 IS NULL AND STOP_CODE = '9'
{code}
Remember that AND has higher priority among operators than OR so if FS25 is greater than FS24 and FS23 the condition will be true even if STOP_CODE is not equal 9.

Expected Outcome:
Bill_date PlanLvl2 PhonenoCount
'01/01/2014' 'SpecialPack1' 1
'01/01/2014' 'SpecialPack2' 3
'01/01/2014' 'Casual1' 1
'01/01/2014' 'Casual2' 1
'01/01/2014' 'PlanA' 1
'01/01/2014' 'PlanB' 1
Basically I have to count all the phone nos grouped by plans in a certain way:
If PlanLvl1 = Bundle, then I have to look at planLvl2 and see if that phone no has ' SpecialPack%' ,and also another plan,them 'Special pack' gets the priority and the phone no gets counted in the special pack.
In case when PlanLvl1 = Bundle and a phone no has both 'Special Packs' as their plans, then the phone no will be counted under the 'Special Pack' with higher Revenue.
In case where PalnLvl is 'Bundle' and a phone no has multiple 'Special Packs' and a non special, that ph no will only be counted once under 'Special Pack; of higher rev as compared to the special pack of lower rev.
Now there are also PlanLvl1 which are 'Non_Bundles' which means they do not have any 'SpecialPacks' but if a ph no with 'NonBundle' plan has 2 different plans under planLvl2, we need to count that ph no for eack planLvl2..
Then there is a scenario where a ph no can have bundles as well as non bundles and in that case we just have to count that ph no in bundles and not in non-bundles.
As I mentioned , 'SpecialPack2' will get a preference over special pack 1 if a phone no has got both of these
Hope this helps

I;m not sure exactly what your rules are since you specify both "In case when PlanLvl1 = Bundle and a phone no has both 'Special Packs' as their plans, then the phone no will be counted under the 'Special Pack' with higher Revenue" and "As I mentioned ,
'SpecialPack2' will get a preference over special pack 1 if a phone no has got both of these". I went with the rule "As I mentioned , 'SpecialPack2' will get a preference over special pack 1 if a phone no has got both of these" since that seemed to match
the result you say you want. I also changed the datatypes to valid SQL Server datatypes.

I`m trying to derived Quarters in my query by using case expression. The Qtr logic is When Servdate and Paid date
are '9/1/2014 and 11/30/2014 then its FiscalYear2015 Q1,
When
Servdate and Paid date
are '12/1/2014 and 02/28/2015 then its FiscalYear2015 Q2,
When
Servdate and Paid date
are '3/1/2015 and 05/31/2015 then its FiscalYear2015 Q3,
When
Servdate and Paid date
are '6/1/2015 and 08/31/2015 then its FiscalYear2015 Q4,
With the above code snippet I`m using I think its working for all quarters except Q2 with above dates I get in my resultset
" Q2NQ " .. Do i need to use a OR predicate am i missing something?

CASE statement with Oacle 8i

I have a problem. I have this SQL :
select SLA_MET_TAB.SLA_MET_COL, count(*),((count(*)/Total)*100), Total
from
(select (case
when (completion_date - approval_date) -
                              (case
                         when to_char(approval_date,'D') < 5 then 0
     when to_char(approval_date,'D') = 5 then 3
                    when to_char(approval_date,'D') = 6 then 2
                         when to_char(approval_date,'D') = 7 then 1
               end -
                    case
                              when to_char(approval_date,'hh24') > 15 then 1
               when to_char(approval_date,'MI') > 0 and to_char(approval_date,'hh24') = 15 then 1
                         else 0
               end -
               case
                         when completion_date in (select holiday from csacweb_owner.holiday) then 1
                    else 0
                         end)< 1.375 then 0
               else 1
          end) SLA_MET_COL
from csacweb.orders
where community_id = 166 and completion_date is not null and approval_date is not null) SLA_MET_TAB,
(select count(*) Total from csacweb.orders where community_id = 166)
group by SLA_MET_TAB.SLA_MET_COL, Total;
Then problem is that when I'm trying to execute, I always have an error message that says : not a GROUP BY expression ... anyone can help me ?

Which version of the database are you running? This simplification of your query runs on my 9.2.0.6 install...

Update Statement with group by query

I need to an update statement that updates the records return from this query:
SELECT
GROUP,
SECTION,
MAX(ASSIGNED_DATE)
FROM
ASSIGNMENTS
GROUP BY GROUP, SECTION
I need to update all those records and set HISTORY = 1
I'm not sure how to form the update statement.
UPDATE ASSIGNMENTS SET HISTORY = 1 WHERE (SELECT
GROUP,
SECTION,
MAX(ASSIGNED_DATE)
FROM
ASSIGNMENTS
GROUP BY GROUP, SECTION) ?

Just doing a select query: (these are the records that were updated when I ran the update statement you posted)
SELECT * FROM ASSIGNMENS WHERE (GROUP, SECTION, ASSIGNED_DATE) IN (SELECT GROUP,
SECTION, MAX(ASSIGNED_DATE)FROM ASSIGNMENTS GROUP BY GROUP, SECTION)
Records:
GROUP SECTION    ASSIGNED_DATE
0010        050098       20011108
0334    000003       19980116
0505        320000       20000712
0676        380000       19980914
0676        067931       20011221
0801        600500       19910409
0801    601701       20090903These are the records I want updated:
Which I would get using:
SELECT GROUP, SECTION, MAX(ASSIGNED_DATE)FROM ASSIGNMENTS GROUP BY GROUP, SECTION
GROUP SECTION ASSIGNED_DATE
0002                  20100519
0003                  20090724
0005
0007       360000
0007                  20040913
0009                  19970814
0010       050098     20011108
0010                  20000926
0011          I'm assuming it skips over null values?
