View with case expression in where statement

Hello,
I want to create a view like:
create or replace view oferte_la_culegere_vw(pcod_lucrare varchar2, pcod_tipprodso varchar2) is
select ol.cod_oferta from oferte_lucrare ol
    join oferte o on o.cod_oferta = ol.cod_oferta
   where ol.cod_tip_lucrare = pcod_lucrare
     and (ol.activ = 'D' or
case when ol.activ = 'I' then
    if os_util.are_atributie(o.atributie_exceptie) then ... -- add condition or ol.activ = 'N' to the query
intersect
select t.cod_oferta from tipinstprodso_oferta
   where t.cod_tipprodso = pcod_tipprodso
order by 1;
show errors view oferte_la_culegere_vw;So in the 1st select i have to filter only for ol.activ = 'D', but i can select records with ol.activ = 'N', only if that condition matches (os_util.are_atributie...).
How can i specify this in a view?
Thanks

Dear,
If I have clearly undestood your requirement you could do this
    select ol.cod_oferta from oferte_lucrare ol
    join oferte o on o.cod_oferta = ol.cod_oferta
   where ol.cod_tip_lucrare = pcod_lucrare
     and (ol.activ = 'D'
       OR(ol.activ = 'N'
          AND CASE WHEN ol.activ = 'I'
              THEN os_util.are_atributie(o.atributie_exceptie
              ELSE
              END = 'xxxx'
                          Best Regards

Error creating view with CASE -- WHEN statement in SQL*Plus

I am using Oracle 8i 8.1.7
I have an Oracle view which uses CASE...WHEN statements.
The view compiles fine in DBA studio.
Using TOAD I saved the view as an *.sql file.
However, when I try to create the view in SQL*Plus I get the following error:
SP2-0734: unknown command beginning "CASE WHEN ..." - rest of line ignored.
According to the documentation CASE -- WHEN has been implemented since since Oracle 8i rel. 2 (8.1.6)

Well I'm using 8.1.6.3 and CASE and DECODE both work for me:
SQL> create or replace view v_accs as select account_name, txn,
2 decode(credit, 0, 'DB', 'CR') t_type

How to use the CASE Expression in Where Cluase?

Hi All,
I'm trying to use the CASE Expression in the Where Clause at some trigger on the Form?
I've tried this Code:
Declare
N Number;
begin
SELECT COUNT(E.EMP_SID)
     INTO N
     FROM EMPLOYEES E, RANKS R
     WHERE CASE WHEN R.qualification_sid = 1104 AND E.rank_sid = 8 THEN
     (TO_DATE(E.RANK_DATE, 'DD-MM-RR')+(365*M.spe_per)+1)
     ELSE
     (TO_DATE(E.RANK_DATE, 'DD-MM-RR')+(365*M.mili_yea_per)+1)
     END
     BETWEEN TO_DATE('01-07-2011', 'DD-MM-RR') AND TO_DATE('31-07-2011', 'DD-MM-RR');
END;
When I run this code as a normal query at any SQL editor it works successfully, But When I Compile it at some trigger on the Form it gives me this error:
Encountered the symbol "CASE" when expecting one of the following:
( - + mod ......
Heeey how to specify the previous code to be shown as code in the thread?
Note: I'm using Forms 6i

OK I tried it and worked but for one condition:
WHERE DECODE (E.qualification_sid, 1104,
     (TO_DATE(E.RANK_DATE, 'DD-MM-RR')+(365*M.spe_per)+1),
     (TO_DATE(E.RANK_DATE, 'DD-MM-RR')+(365*M.mili_yea_per)+1))
     BETWEEN TO_DATE('01-07-2011', 'DD-MM-RR') AND TO_DATE('31-07-2011', 'DD-MM-RR')
But how to put two conditions for the same Expression:
WHERE DECODE ((E.qualification_sid, 1104) AND (E.RANK_SID, 8),
     (TO_DATE(E.RANK_DATE, 'DD-MM-RR')+(365*M.spe_per)+1),
     (TO_DATE(E.RANK_DATE, 'DD-MM-RR')+(365*M.mili_yea_per)+1))
     BETWEEN TO_DATE('01-07-2011', 'DD-MM-RR') AND TO_DATE('31-07-2011', 'DD-MM-RR')
The previous code gives me this error: missing right parenthesis

Cube or Group By columns with Case Expressions with a total row (SQL Server 2008)

I am trying to create a summary tabe of some data. I think that I can use Cube(my heart is not set on it though), but I cant figure a way to define new columns via a case expression and sum the new column. Lastly, I need to create a total row at the
bottom and I have no idea of how to do that except percent run the query and then run it again without the travel_city and union all the two tables
group by travaled_city, [COL1] =sum(expense) when dept = 1, [COL2]=sum(expense) when dept = 2, [COL3] = sum(expense) when group = 3, =[COL4]=sum(expense) when group = 1 and expense code = 0100,[COL5]= sum(expense) when group = 2 and expense code
= 0100, [COL6]sum(expense) when group = 3 and expense code = 0100, [COL7]=sum(expense) when (exp_paid)<30, [COL8] = sum(expense) when dept in ('4','5','6')
and have a grand total of each column
any help is greatly appreciated

Would this work?
select travaled_city,
sum(case dept when 1 then expense else 0 end) as [COL1],
sum(case dept when 2 then expense else 0 end) as [COL2], ...

Case expression in where clause

I have requirement to select a columns based on condition Datacode should (when the column id=1 THEN 'GILL' ELSE WHEN ID=11 THEN IT Should be 'HEL'
how can i write in case statment
AND DATA_CD =CASE WHEN ID=1 THEN 'GIL'
WHEN ID=11 THEN 'HEL'

what happens to the ELSE PART?It is for you to tell what happens to the ELSE part.
If the ID is not 1 or 11, then your AND condition fails and probably your query will not retrieve any records for you (Assuming this query is not a part of OR condition, because there is no query provided.).
Because, without ELSE, the default shall be set to NULL and since you used "DATA_CD =", NULL shall not equate with it resulting in failure of condition. Hence, I would suggest you to add some default value in the ELSE part.

What exactly are your expecting the below given segment to display? Two different columns? (That's not the way to get it done)
        CASE when p.ASSIGNED is null then
            SUM (
                CASE WHEN P.STATUS = 'waiting' AND P.TYPE_ID=1 and trunc(P.INSERT_DATE)= trunc(Sysdate)
                and p.INITIATED_BY = 51 and p.IS_DELETE='No' THEN 1 ELSE 0 END
            SUM (
                CASE WHEN P.STATUS = 'waiting' AND P.TYPE_ID=1
                and p.INITIATED_BY = 51 and p.IS_DELETE='No' THEN 1 ELSE 0 END
        )also you cannot alias a column within case..end.

Hierarchy on HANA Calculation View with Optional Input Parameters Fails

Hi,
Has anyone succeeded in building a hierarchy on top of a calculation view with optional input parameters, where an input parameter is not filled?
The original requirement came from the wish to create a parent child hierarchy on a calculation view that was copied into the customer space from a HANA Live Financial Statement query view, but I have found the following when creating a simple level hierarchy on a calculation view that consumes one table. The Calculation View has one Input Parameter where the 'mandatory' box is unchecked.
Calculation view reads ECC table FAGLFLEXT
Simple level based hierarchy on fields PRCTR, RACCT and SEGMENT
Input parameter is used as a filter for PRCTR with logic ("EMPTY" = '$$P_PROFITCTR$$' or "PRCTR" = '$$P_PROFITCTR$$')
When I run the view I see the following behaviour in HANA Studio and Analysis for Excel
Before building the hierarchy I could run the view with or without the Input Parameter
After building the hierarchy I can run the view with the Input Parameter filled, but it fails when the Input Parameter is not filled.
Error message is "error: search table error: [2426] missing placeholder; missing value for mandatory parameter P_PROFITCTR"
P_PROFITCTR is not a mandatory parameter, but the selection for the hierarchy view thinks it should be. I don't find any notes around this issue, so I don't think it's version related, however the version I have used for this test is 1.00.70.
It's a shame we can't currently build the hierarchy as the parent child relationship is provided in HANA Live view NewGLFinancialStatementQuery.
Thanks,
Ken

Hi Ken,
We have been facing similar issue. We have even tried to set default value and as optional parameter. View still fails to create hierarchy (we are not using HANA live). As mentioned on page 97 of HANA modelling guide input parameter is mandatory from engine point of view. Hierarchy is generated as column view during the initial activation of calculation view and therefore expect a value by caller.
This seems to be a product error. Some one from HANA development team should explain this issue in detail. I would expect someone like Thomas Jung reply to us.
At the moment, we cant use input parameter for date prompt which gives us calendar popup feature for date selection. Hierarchies just don't work with input parameter. We are missing something.

Case expression doubt

hi all,
which is better to use in below two query's.
select empno from emp where deptno=10
union all
select empno from emp where deprno=20
or
select
case when deptno=10 then empno end case ,
case when deptno=20 then empno end case
from
emp
which is better?
will case expression in select statement will effect the performance?

hi thanks for reply ,
now consider these two Please try the queries yourself before posting them. Ask specific questions, such as "Why does the first query produce ...?" or "I though the second query would produce ... using the standard scott.emp table. Why doesn't it?"
select empno,null from emp where deptno=10
union all
select null,empno from emp where deptno=20The query above will only produce results for rows where deptno=10 or 20 (a total of 8 rows in the standard scott.emp table).
and
select case when deptno=10 then empno else null end case ,
case when deptno=20 then empno else null end case from emp order by 1,2This second query will produce one output row for every row in the table (14 rows in the standatd scott.emp table. 8 of those rows will be the same as returned by the first query, and the other 6 will have NULL in both columns.) Also, both columns have the same alias, CASE. (The keyword to end a CASE expression is just END. If you say END CASE, then CASE is taken to be a column alais.)
The following gets the same results as your first query:
select case
         when deptno=10 then empno
                       else null
     end                    AS empno_10
,     case
         when deptno=20 then empno
                       else null
     end                    AS empno_20
from      emp
WHERE     deptno     IN (10, 20)
;This will be more efficient than a UNION, because it only has to make one pass through the table.

Detail view with bind variable. TreeTable not showing all detail result.

I’m having trouble with treeTable using detail view with bind variables and where clause defined in VO definition.
Both, master and detail view objects, base on the same entity and have the same condition in where clause. The view objects also have bind variables, which are set in prepareRowSetForQuery() method.
Again, these are two different views, that get different result, based on value of one of the bind variable.
When I show results in two different tables on jsf page, where master table has "RowSelection" set on "single", all results are displayed in detail table.
But when I use treeTable, only the first result of the detail is shown.

I tested it in applicationModule and it works, but i think that's the same as two tables on a jsf page.
This is the order in which overridden methods are called in ADF BC or two tables on jsf page
when clicking on row in master table.
PrepareRowSetForQueryDetail
executeQueryForCollection_Detail user param: 2
   Object 2: class [Ljava.lang.Object; -> print of the object2[] parameter in executeQueryForCollection
     List 0: Bind_ChildId -> viewLink parameter
     List 1: 400035313 -> viewLink parameter value
getEstimatedRowCount_Detail
count: 2
getEstimatedRowCount_Detail
count: 2 And when i click on "expand node" in tree table:
getEstimatedRowCount_Root
count: 2
PrepareRowSetForQuery_Detail
executeQueryForCollection_Detail user param: 2
   Object 2: class [Ljava.lang.Object;
     List 0: Bind_ChildId -> viewLink parameter
     List 1: 400035321
PrepareRowSetForQueryDetail
executeQueryForCollection_Detail user param: 2
   Object 2: class [Ljava.lang.Object;
     List 0: Bind_ChildId -> viewLink parameter
     List 1: 400035313
getEstimatedRowCount_Root
count: 2
getEstimatedRowCount_Root
count: 2
getEstimatedRowCount_Root
count: 2
PrepareRowSetForQueryDetail
executeQueryForCollection_Detail user param: 2
   Object 2: class [Ljava.lang.Object;
     List 0: Bind_ChildId -> viewLink parameter
     List 1: 400035313
PrepareRowSetForQueryDetail
executeQueryForCollection_Detail user param: 2
   Object 2: class [Ljava.lang.Object;
     List 0: Bind_ChildId -> viewLink parameter
     List 1: 400035321
getEstimatedRowCount_Root
count: 2
getEstimatedRowCount_Root
count: 2Values of user parameters are OK. Is there another method that i should override?
I also noticed, that if detail view doesn't have user bind variables, the tree works fine and is shown even in ADF BC (aplication module).
I guess we loose a tree, when using bind variables in detail view object.
Is there a way around it?

Now I need to fetch the employees whose hire date is between 01-APR-1981 and 31-DEC-1981. If the hire date is null, then confirmation date has to be considered.
For this input the following employees's records should be returned:
7566
7654
7698
7782
7839
7844
7900
7902
I tried with CASE, DECODE in WHERE clause. But I couldn't succeed. Please help.
Thanks in advance.

Using CASE in the join statement in the AND clause. Where's the problem?

All,
I have my code, where based on the case statement, I would like to restrict the number of records in my JOIN condition. It's the CASE statement that I have used, that's giving me the problem. Not sure, what the problem is. The error says (in my case expression):
Msg 102, Level 15, State 1, Line 59
Incorrect syntax near '>'.
Select a.Col1, a.Col2, b.Col1, b.Col2, b.Col3
From Table1 a
Join Table2 b
On a.id = b.id
Join Table3 c
On c.FiltId = a.FiltId
And
Case
When b.Col3 <> 5 --b.Col3 is an INT field
Then (b.OutDate >= DATEADD(DAY, -30, c.InsertDate) And b.OutDate <= DATEADD(DAY, 30, c.InsertDate))
When b.Col3 = 5
Then (b.InDate >= DATEADD(DAY, 5, c.InsertDate))
End
Join Table 4 -- Other Join conditions and where clause conditions

You do not know the CASE is an expression and fields are not columns. This is fundamental and probably means that a lot of your code needs work.
You can probably re-write the query with something like this:
SELECT A.col1, A.col2, B.col1, B.col2, B.col3
FROM Table_1 AS A, Table_2 AS B, Table_3 AS C
WHERE A.generic_id = B.generic_id
AND C.foobar_id = A.foobar_id
AND CASE
WHEN B.col3 <> 5
AND (B.something_out_date
<= DATEADD(DAY, -30, C.something_insertion_date)
THEN 'T'
WHEN B.col3 = 5
AND (B.something_out_date
>= DATEADD(DAY, -30, C.something_insertion_date)
THEN 'T'
ELSE 'F' END = 'T' ;

11g outer join with case statement - strange results.

Hello All,
I am experiencing a strange issues in 11g while using case statement.
I am not able to reproduce this using sample data. Not sure what is wrong.
I am not narrowing it to say the usage of case statemnt is giving wrong results, but that is my observation when I am doing trail and error testing.
Here are the details.

Are there any other viable solutions?
I appreciate the help.
Thanks,

Right, the query transformation is going wrong. Following is from trace,

Writing single query with conflicting WHERE statements

How do I run the following as a single query that will result in a column that pertains to the first block of code and then another column that pertains to the 2nd block of code? The issue is that I need 2 different WHERE statements. So the final output will be patient_id, complete, incomplete.
SELECT patient_id, COUNT(*) AS complete
FROM STATUS
WHERE status = 1
GROUP BY patient_id
ORDER BY patient_id;
SELECT patient_id, COUNT(*) AS incomplete
FROM STATUS
WHERE status = 2
GROUP BY patient_id
ORDER BY patient_id;
Thanks!

Thanks for all of the help.
I would like to add another column with decile and am struggling as to how to do it. Since I can't reference something in a calculation in the same step, I think I will need a 3rd nesting, but what I haven't figured out is how to get the number of subjects whose ratio is less than that subject's ratio. Right: you can't assign an alias (such as complete or ratio) to a calculated column and use that alias in the same sub-query.
If the calculation isn't very complicated, then you might find it simpler just to repeat the calculation. For example, I think this is what you want:
WITH     got_complete     AS
     SELECT    patient_id
     ,        COUNT ( CASE WHEN status = 1 THEN 1 END )     AS complete
     ,       COUNT ( CASE WHEN status = 2 THEN 1 END )      AS incomplete
     FROM        pt_status
     WHERE        status IN (1,2)
     GROUP BY patient_id
SELECT       patient_id, complete, incomplete
,                                complete / (complete + incomplete)     AS Ratio
,       RANK () OVER ( ORDER BY complete / (complete + incomplete) ) - 1
                                                    AS decile
FROM      got_complete
ORDER BY complete
,            incomplete     DESC
;RANK numbers rows 1, 2, 3, ... If I understand your requirements, you want the numbering to start with 0 (meaning "there are 0 other patients with a lower ratio"), so that's why I subtracted 1.
Depending how you want to handle ties, you may need to add some tie-breaker expressions to the analytic ORDER BY clause, and/or use ROW_NUMBER instead of RANK.
Here, I used the calculation "complete / (complete + incomplete)" in the ratio column, then repeated it in the decile column.
I you want, you can add another sub-query, called got_ratio, which would add the ratio column, but do nothing about the decile column. Then, in the main query, you could use RANK as shown above (or, as you suggested, a scalar sub-query referencing got_ratio) to get the number of other pateient_ids with lower ratios.
On the other hand, you could do this whole job without any sub-queries, using AVG as I did earlier, and then repeating that same AVG expression in the ORDER BY clause for RANK. Aggregate functions are computed before analytic fucntions, so the analytic RANK can referenece the aggregate AVG.
I hope this answers your question.
If not, post a little sample data (CREATE TABLE and INSERT statements, relevant columns only), and also post the results you want from that data. Include examples of decile ties (2 or more patients with the same ratio).
Explain, using specific examples, how you get those results from that data.

Update with case statement problem.

Hi,
I have this statement
update tab_tr set col_rate =
case
when col_ern_type in ('031','035','036') then (1.5 * col_rate)
when col_ern_type in ('041','045','046') then (2 * col_rate)
end;this statement updated some 2 million rows in the table tab_tr. But the total count of rows for col_ern_type in ('031','035','036', '041','045','046') yeild only around 222642 rows.
select count(*) from tab_tr where col_ern_type in ('031','035','036', '041','045','046'); --> 222642 rowswhat is the problem with the above update statement.
Thank you,

For example, which rows do you think this should update?
UPDATE tab_tr
SET     col_rate = 100;It would update all rows, of course.
How about this statement?
UPDATE tab_tr
SET     col_rate = column_x;Will it only change the rows where column_x are a certain value, or not NULL, or in any way depend on column_x? No, of course not. It will update all rows.
How about this statement?
UPDATE tab_tr
SET     col_rate = function_y (col_ern_type);Will it only change the rows where the fucntion returns a certain value? Will it depend on the value in col_ern_type? No, of course not. It calls the function for each row, and whatever the function returns (even if the function returns NULL), that's what goes into col_rate on each row.
A CASE expression is just something that you can substitute in place of any other expression, such as the literal 100, or the column column_x, or the function function_y in the statements above. Naturally, the value that gets put into col_rate will depend on what the CASE expression returns, but the behavior of the UPDATE statement as a whole will not.
