ABAP - Case Statement

Hi ABAPers,
I have an ABAP code just like the pseudo code below.
Case Val.
When 'A'.
<Some Conditional Statements>.
When 'B'.
<Some Statements>.
endcase.
A and B values are depend on 'Val'.
My program executes the above code almost everytime. when the conditional statement of Case (A) is successful, then I dont want my program to execute the case(B).
When the conditional statement of case(A) is unsuccessful, then only i want to execute case (B). Can anyone please tell me how to correct my code to suit the above situation.
Thanks,
Creasy Matt

ABAP - CASE STATEMENT - How to get out of WHEN statement??

Hi ABAP experts,
I am implementing an User exit related to inbound Sales order.
All my IDoc contain, E1EDP02 001
                               E1EDP02 002 segments.

lv-tabix = sy-tabix + 1.
Read int_edidd into wa_edidd index lv_tabix.
if wa_edidd-segnam = 'E1EDP05'
if wa-e1edp05-qualf = '002' " Always this is giving the current segment data. when i debug, it is showing QUALF = '001'. What should i do here to get the next segment data.
EXIT.

Can anyone tell me what should i do in the first WHEN statement to check the next segment qualifier.
Thanks and Waiting for your answer.

ur question is not clear...
Case w_e1edp02-qualf.
when '001'
clear lv-tabix.
lv_tabix = lv_tabix + 1.   "seems u want to loop wa_edidd
Read int_edidd into wa_edidd index lv_tabix.
if wa_edidd-segnam = 'E1EDP05'
if wa-e1edp05-qualf = '002' "            "is it the correct work area????
EXIT.
else.
<statements>.
endif.
when '002'.
<statements>.
endcase.
i think u can do like dis...
Case w_e1edp02-qualf.
when '001'
LOOP AT int_edidd into wa_edidd .
if wa_edidd-segnam = 'E1EDP05'
if wa-edidd-qualf = '002'
EXIT.
else.
<statements>.
endif.
ENDLOOP.

SQL Expression in decode function or case statement?

Can I put SQL expressions in decode function or case statement?
For example,
select le.profile, decode( select count(1) from profile_data where NAME= 'XXXX_AFTER' and object_id = le.profile, 0, 'N', 'Y')
from element le;
or
select le.profile, case WHEN ( select count(1) from profile_data where NAME= 'XXXX_AFTER' and object_id = le.profile) = 0 THEN 'N'
ELSE 'Y'
from element le;
None of the above work.
Can anyone tell me how to make it work?
Is there any workaround?
Thanks,
J

You simply needed and END to your CASE statement;
SQL> with profile_data as (
   select 'XXXX_AFTER' name, 1 object_id from dual),
     element as (
   select 1 profile from dual union all
   select 2 from dual)
select le.profile,
   case WHEN ( select count(1) from profile_data where NAME= 'XXXX_AFTER' and object_id = le.profile) = 0
   THEN 'N'
   ELSE 'Y'
   END new_col
from element le
   PROFILE N
         1 Y
         2 N

CASE not found while executing CASE statement on Submit Form

I have several APEX applications and they are all working well, but recently I got one strange exception when I try to submit page:

Page has more than 120 items (most of them are hidden), so my first thought is that page has problem with posting so many items, but APEX error message doesn't hel me at all. Any help would be very appreciated :)
Almir

Hi Almir,
actually it is the 100 page item limit. See (http://download.oracle.com/docs/cd/E17556_01/doc/user.40/e15517/limits.htm)
I also had a look into the source code and the code at the position where the error gets raised only supports 100 page items.
Can you have a look into the generated HTML code and look if you have a page items which is mapped to p_t101 or a higher number ?
I will file a bug to show a better error message.

Case statement

hi.
i have a case statement query. i wonder if in the select statement, can i do computation using different parameter from the main report to subreport?
for example, (qty * parameter)
if parameter = 0, i uses $P{abc} to multiply qty
if parameter > 0, i uses $P{xyz} to multiply qty
in this case, i've writen a sql (as below) but its does not execute.
select ....., (QTY *
case $P{QTY}
when 0 then ' * $P{abc}'
else ' $P{xyz}'
end
from....
hence, what should i do in order to get the right parameter to multiply with? pls guide. thanks.

I'm not sure about these parameter placeholders which are specific to whatever report tool you are using, but the structure would be (assuming the parameter value would never be less than zero):
qty * case when $P{QTY} = 0 then $P{abc} else $P{xyz} end

Case Statement in Answers Filter

Hi,
I'm trying to build a query in Answers that filters the data returned based on the current month number. If the current month is 1 then we want to show all 12 months, otherwise we want to show months less than the current month. If I use the following:
CASE WHEN extract(month from current_date) = 1 THEN "Calculated Values Monthly"."MONTH" >= 1 ELSE "Calculated Values Monthly"."MONTH" < extract (month from current_date) END
I get the error below. All works fine until I add the CASE.

ThxAccording to your requirements, when the month is January, you want all 12 months; any other number and you want months from 1 to "1 less than the current month number." Yes? Okay, here's what to do:
In the filter on your date column, click on the filter button, convert it to SQL and enter this:
MONTH(tablename.date_column) BETWEEN 1 AND CASE WHEN MONTH(CURRENT_DATE) = 1 THEN 12 ELSE MONTH(CURRENT_DATE)-1 END
Here's the logic:
a) When the current month is January, then the case statement will yield 12 and the filter will be:
WHERE MONTH(tablename.date_column) BETWEEN 1 AND 12 ...or all 12 months.
b) When the current month is any other month, say June, then the case statement will yield one less than the what the month number is, or in this case 5.
WHERE MONTH(tablename.date_column BETWEEN 1 AND 5 ...or all the months from 1 to 5 (Jan through May)
This will give you what you want...

Case statement in advanced sql

how to use case statement in advanced sql.Example if quarter=1 i need to select jan,fev,and march months from table

this is the case statement i am using :
case when 1=@{quarter} then substring(cast((etxnmis.month_year) as char) from 5 for 2) IN ('03', '04', '05') else null end
and i get the below error
: HY000. Code: 10058. [NQODBC] [SQL_STATE: HY000] [nQSError: 10058] A general error has occurred. [nQSError: 27002] Near <IN>: Syntax error [nQSError: 26012] . (HY000)

T-sql case statement in a select

When I execute the following t-sql 2012 statement, the "NO Prod' value is not
being displayed from the sql listed below:
SELECT DISTINCT
IsNull(cs.TYPE,'') as type,
CASE IsNull(Course.TYPE,'')
WHEN 'AP' then 'AP Prod'
WHEN 'IB' then 'IB Prod'
WHEN 'HR' then 'HR Prod'
WHEN '' then 'NO Prod'
END AS label
FROM CustSection cs
INNER JOIN dbo.Person p on P.personID = cs.personID
Left join customCustomer cs564 on cs564.personID = p.personID and
cs564.attributeID ='564'
   where ( cs.type is null and cs564.attributeID = null)
     or
    (cs.type IN ('HR','AP') OR
      (cs.type='IB' AND SUBSTRING(cs.code,1,1)='3'))
ORDER BY label
What I want is for 'NO Prod' to be displayed when
cs.type is null and cs564.attributeId is null.
Thus can you tell me how to fix query above so the 'NO Prod' value is displayed in the
select statement listed above?

There is no CASE statement in SQL; we have a CASE expression. We do not use the old 1970's Sybase*- ISNULL(); we have COALESCE().
There is no such thing as a magic generic “type” in RDBMS. There is no such thing as a generic “code” in RDBMS. They have to to be “<something in particular>_type” and “<something in particular>_code” in a valid data model. How about blood_type
and postal_code??
There is no such thing as a generic “person” table in RDBMS. First of all, do you really have only one person, as you said?? But the important point is that these persons play a role in the data model – customers, students, etc. You are doing the wrong thing
and doing it badly. This table should not exist any more than a table of “Things” such exist.
And the reason you are beyond any real help is “attribute_id” which tell us that your schema is a total disaster of data and meta data mixed together in a non-RDBMS written in awful SQL. Based on cleaning up bad SQL for 30 years, it looks like you are an OO
programmer who never unlearned his prior mindset.
Why did you allow an encoding schema with blanks? Why do you have so many NULL-able columns?
SELECT DISTINCT is very rare in a properly designed schema. The DRI references assure that rows cam be matched. To get you started, look at this skeleton:
CREATE TABLE Products
(product_gtin CHAR(15) NOT NULL PRIMARY KEY,
product_type CHAR(2) DEFAULT 'XX' NOT NULL
CHECK (product_type IN ('AP', 'IB', 'HR', 'XX'))
The table name is a plural noun because it models a set (NOT an OO class).
The GTIN is an industry standard identifiers, and not have to invent our own.
The product_type (not blood_type, not automobile_body_type!) has a constraint that assures it is never NULL and never blank; I invented 'XX' as a default.
You need more help than you can get in a forum, but if you will follow Netiquette and post the DDL, we can get you started.

CASE Statement in a SELECt

I want to do something like this in a SELECT where I set the value of one field based on another. Is this possible. If not are there any alternatives? Thanks
CASE WHEN [var_cpnt_brkpt_ct] = '0' THEN [enrc_cpnt_var_price_rt] = '0'

There is no CASE statement in SQL; we are a declarative language. We have a case expression! There is no control flow, like you are trying to write. You do not even know that fields are columns. This is as silly
as asking for the color the feathers on a fish.

CASE Statement in Where Condition with Multi Valued parameter in SSRS

Hi All,
I am little confused while using CASE statement in Where condition in SSRS. Below is my scenario:
SELECT
Logic here
WHERE
Date IN (@Date)AND
(CASE
WHEN NAME LIKE 'ABC%' THEN 'GROUP1'
WHEN ID IN ('123456', '823423','74233784') THEN 'GROUP2'
WHEN ABC_ID IS NULL THEN 'GROUP3'
ELSE 'GROUP4'
END ) IN (@GROUP)
So above query uses WHERE condition with CASE statement from @GROUP parameter. I want to pass this parameter as multi- valued parameter and hence I have used CASE statement IN (@GROUP).
For @Date one dataset will pass the available and default values and
for @GROUP parameters, another dataset will pass the available and default values.
But this is not working as expected. Please suggest me where I am making mistake in the query.

According to your description, I create a sample report in my local environment. It works as I expected. In your scenario, if the selected values from the Date parameter contains some of the Date field values, the selected values from the GROUP parameter
contains some of GROUPS (‘GROUP1’,’GROUP2’,’GROUP3’,’GROUP4’) and the corresponding when statement is executed , then the dataset returns the corresponding values.
In order to trouble shoot this issue, could you tell us what results are you get and what’s your desired results? If possible, you can post the sample data with sample dataset, then we can make further analysis and help you out.
Thanks,

Using null in CASE statements

Hi,
I have query with a case statement as follows:
SELECT * FROM table
WHERE
CASE WHEN :variable like 'A' THEN column END is null
WHEN :variable like 'B' THEN column END is not null;
This works fine when returning "column is null" but not when "column is not null".
Can I use a CASE statement like this?
Thanks
Lucy

My data is too complicated to show, but depending on the value of the bind variable in the statement I want to return all the rows in a query where the data in a particular column is either null or not null.For example, looking at the EMP table, if my bind variable is whether I want to show the top manager or not, if set to 'Yes' I would like to return all rows of the EMP table where mgr is null (i.e. the one row where ename is 'KING'), if it were set to 'No' I would like to return all the rows where mgr is not null (i.e. all the other rows). The difference with my query is that the column contains strings, not numerics.
I've used a CASE statement before where I equate the column to a particular value and that works fine, but I'm not sure how they deal with nulls. I've also tried DECODE and didn't get anywhere with that.
Thanks

How do I use the CASE statement in the where clause?

Hello Everyone,
I have 2 queries that do what I need to do but I am trying to learn how to use the CASE statement.
I have tried to combine these 2 into one query using a case statement but don't get the results I need.
Could use some help on how to use the case syntax to get the results needed.
thanks a lot
select segment_name,
product_type,
count (distinct account_id)
FROM NL_ACCT
where
ind = 'N'
and
EM_ind = 'N'
and product_type in ('TAX','PAY')
and acct_open_dt between (cast('2006-01-17' as date)) and (cast('2006-01-17' as date) + 60)
GROUP BY 1,2
order by product_type
select segment_name,
product_type,
count (distinct account_id)
FROM NL_ACCT
where
ind = 'N'
and
EM_ind = 'N'
and product_type not in ('TAX','PAY')
and acct_open_dt between (cast('2006-01-17' as date)) and (cast('2006-01-17' as date) + 30)
group by 1,2
order by product_type

Something like:
SELECT segment_name, product_type,
       SUM(CASE WHEN account_id IN ('TAX','PAY') and
                     acct_open_dt BETWEEN TO_DATE('2006-01-17', 'yyyy-mm-dd') and
                           TO_DATE('2006-01-17', 'yyyy-mm-dd') + 60 THEN 1
                ELSE 0 END) tax_pay,
       SUM(CASE WHEN account_id NOT IN ('TAX','PAY') and
                     acct_open_dt BETWEEN TO_DATE('2006-01-17', 'yyyy-mm-dd') and
                           TO_DATE('2006-01-17', 'yyyy-mm-dd') + 30 THEN 1
                ELSE 0 END) not_tax_pay
FROM NL_ACCT
WHERE ind = 'N' and
      em_ind = 'N' and
      acct_open_dt BETWEEN TO_DATE('2006-01-17', 'yyyy-mm-dd') and
                           TO_DATE('2006-01-17', 'yyyy-mm-dd') + 60
GROUP BY segment_name, product_type
ORDER BY product_typeNote: You cannor GROUP BY 1,2, you need to explicitly name the columns to group by.
