I have a table named VWDRSSTA and it has the following fields
SYSTEM,
EREIGNIS;
DATUM_ZEIT,
ANTRAGSNUMMER,VORGANGSNUMMER,VERS_NR_INT,
DOK_ART,
DUNKEL
I am looking to create a view of this table with a filter in two fields DOK_ART and DUNKEL using CASE statement. Here is what I tried doing
CREATE VIEW VWDRSSTA_VIEW As
SELECT SYSTEM, EREIGNIS, DATUM_ZEIT, ANTRAGSNUMMER, VORGANGSNUMMER, VERS_NR_INT,
CASE
WHEN EREIGNIS = 'EIN-ES' AND DOK_ART = 'EN' Then 'EN'
ELSE ''
END
CASE
WHEN EREIGNIS = 'POL_AN' AND DUNKEL = 1 Then 1
ELSE ''
END
FROM VWDRSSTA;
Which is going wrong. How can I achieve the above?
Try this:
CREATE OR REPLACE FROCE VIEW VWDRSSTA_VIEW As
SELECT SYSTEM, EREIGNIS, DATUM_ZEIT, ANTRAGSNUMMER, VORGANGSNUMMER, VERS_NR_INT,
CASE
WHEN EREIGNIS = 'EIN-ES' AND DOK_ART = 'EN'
THEN 'EN'
ELSE ''
END AS DOK_ART,
CASE
WHEN EREIGNIS = 'POL_AN' AND DUNKEL = 1
THEN 1
ELSE ''
END AS DUNKEL
FROM
VWDRSSTA;

I have a table with fields man_phone and head_phone, and in the selects there are such cases for obtaining them:
case
when p.dep_code <> 'MM' then
case
when p.man_id = '%%%%%%%' then
'Man Spec-100'
when m.man_l is not null then
m.man_phone
else
case
when m2.man_l is not null then
m2.man_phone
else
m3.man_phone
end
end
else
o.cont_phone
end as man_phone,
case
when p.dep_code <> 'MM' then
case
when p.man_id = '%%%%%%%' then
'Man Spec-100'
when m2.man_l is not null then
m2.man_phone
else
m3.man_phone
end
else
o.head_phone
end as head_phone
I want to add a new field called head_login with a case if man_phone = head_phone, then it will output man_l as head_login and I tried to push these two existing cases into only one case, what would be the right way to do this?
case
case
when p.dep_code <> 'MM' then
case
when p.man_id = '%%%%%%%' then
'Man Spec-100'
when m.man_l is not null then
m.man_phone
else
case
when m2.man_l is not null then
m2.man_phone
else
m3.man_phone
end
end
else
o.cont_phone
end as man_phone,
case
when p.dep_code <> 'MM' then
case
when p.man_id = '%%%%%%%' then
'Man Spec-100'
when m2.man_l is not null then
m2.man_phone
else
m3.man_phone
end
else
o.head_phone
end as head_phone
when p.department_code <> 'MM' then
case
when man_phone = head_phone
m2.man_l
else
m3.man_l
end
end as head_login
I want to add a new field called head_login with a case if man_phone = head_phone, then it will output man_l as head_login and I tried to push these two existing cases into only one case.
Do not try to merge the two cases into a third case. Evaluate them in a sub-query and then put the CASE which compares them into an outer query:
SELECT man_phone,
head_phone,
CASE
WHEN man_phone = head_phone
THEN man_l2
ELSE man_l3
END AS head_login
FROM (
SELECT CASE <your case> END AS man_phone,
CASE <your case> END AS head_phone,
m2.man_l AS man_l2,
m3.man_l AS man_l3
FROM table_name
)
I'm getting multiple results from these statements and want to concatenate these. Please help with syntax and structure
(SELECT NVL (
CASE WHEN (csi.hello = DT.S)
THEN 'Task IS ALREADY DONE'
WHEN VV.Mo LIKE NULL
THEN 'The model is not available'
WHEN (B.tsk = '7')
THEN 'The task status has been Cancelled'
WHEN (B.tski = '14')
THEN 'The task has been Assigned'
WHEN (B.tsko = '11001')
THEN 'The task has been Return Part STATUS'
END, '')RMA_CRITERIA,
Use string concatenation:
SELECT (CASE WHEN csi.hello = DT.S THEN 'Task IS ALREADY DONE;' ELSE '' END ||
CASE WHEN VV.Mo IS NULL THEN 'The model is not available;' ELSE '' END ||
CASE WHEN B.tsk = '7' THEN 'The task status has been Cancelled;' ELSE '' END ||
CASE WHEN B.tski = '14' THEN 'The task has been Assigned;' ELSE '' END ||
CASE WHEN B.tsko = '11001' THEN 'The task has been Return Part STATUS;' ELSE '' END
) as RMA_CRITERIA,
Note that this adds a separator (;), although you do not specify one. Also LIKE NULL always returns the equivalent of false; I assume you intend IS NULL. And the ELSE '' is redundant in Oracle, but it makes the intention clear.
I am trying to Migrate client's data and this error happened during the migration procedure. I have searched around and the possible solution is to trim or use DBMS_LOB.SUBSTR, but i do not know where to put them in. It could be this part (TO_CHAR(AIMSCMDDL_AT.BIOS_SEQ.nextval) but i am still new to SQL and not sure what could be the cause of the problem. Can anyone guide me on how to solve this problem? Thank you!

Most likely it comes from one of these expressions:
CASE
WHEN TO_CHAR(INSTALLER_SIGNATURE) = null
THEN null
ELSE 'NULL'
END
First, they don't work. ... = NULL never yields TRUE. Is IS NULL instead.
There is no need to use TO_CHAR(), IS NULL works for any data type.
And you can write it shorter as
INSTALLER_SIGNATURE = NVL2(INSTALLER_SIGNATURE, 'NULL', NULL)
NB,
REGEXP_LIKE(substr(CUST_DECLARATION_AUTH_ID,1,1),'[A-Za-z]')
and REGEXP_LIKE(substr(CUST_DECLARATION_AUTH_ID,-1,1), '[A-Za-z]')
can be written as
REGEXP_LIKE(CUST_DECLARATION_AUTH_ID,'^[A-Za-z].*[A-Za-z]$')
Hello i have a quation with my stored procedure , i use 2 cases here , the first case it shows me right values and its OK, the second shows me only Null values in the field TirType , i don't understand what is the problem

Don't forget END after CASE. It will return NULL if no ELSE is specified and value is not '714'.

After some previous help on how to approach a problem I am having with some legacy code, it seems like the best approach for my issue is to concatenate case statements to return a value I can parse out in PHP.
I am trying to do something like this, but it is returning many rows, and eventually getting this error:
Maximum stored procedure, function, trigger, or view nesting level
exceeded (limit 32).

Well, this is embarrassing.
When I was making my changes to the stored procedure, I had inadvertently placed a call to the same procedure at the bottom. So I was recursively calling the same procedure over and over again. DOH.
