I need to Create 3 Variables from 1 Variable SQL Oracle SAP - sql

Question

I’m working on creating three variables in the my Universe. The variables are Applications, Operating System, and Physical Location. The problem I’m running into is that all three of these is pulled from the same table and all of them are within the Value.
So the Table BMC_CORE_BMC_BASERELATIONSHIP has the variable Name. I am trying to pull all of the destination instance id's for the operating system when name is equal to SYSTEMOS.
My first guest was to use derived tables having each of the three a separate table with the following coding
“Operating System Relationship” Derive Table
SELECT
BMC_CORE_BMC_BASERELATIONSHIP.DESTINATION_INSTANCEID
FROM
BMC_CORE_BMC_BASERELATIONSHIP
Where
BMC_CORE_BMC_BASERELATIONSHIP.Name = 'SYSTEMOS'
“Physical Location Relationship” Derive Table
SELECT
BMC_CORE_BMC_BASERELATIONSHIP.DESTINATION_INSTANCEID
FROM
BMC_CORE_BMC_BASERELATIONSHIP
Where
BMC_CORE_BMC_BASERELATIONSHIP.Name = 'ELEMENTLOCATION'
“Applications Relationship” Derive Table
SELECT
BMC_CORE_BMC_BASERELATIONSHIP.DESTINATION_INSTANCEID
FROM
BMC_CORE_BMC_BASERELATIONSHIP
Where
BMC_CORE_BMC_BASERELATIONSHIP.Name = 'APPLICATIONSYSTEMCOMPUTER'
However when I try pulling the variable in with the following syntax, only one of the variables will show up in Webi. The others are being nulled I figured out.
App Var
Case
WHEN CI_RELATED_CI.INSTANCEID ="Applications Relationship".DESTINATION_INSTANCEID
Then CI_RELATED_CI.NAME
END
Location Var
CASE
WHEN CI_RELATED_CI.INSTANCEID = "Physical Location Relationship".DESTINATION_INSTANCEID
THEN CI_RELATED_CI.NAME
END
OS Var
Case
WHEN CI_RELATED_CI.INSTANCEID ="Operating System Relationship".DESTINATION_INSTANCEID
Then CI_RELATED_CI.NAME
END
I was trying to think of a way to pull all of these into one derived table as separate variables, but so far I have been unsuccessful. Any thoughts or suggestions would be appreciated. I'm new so let me know if there is anything I can do to make my questions better.

Answer 1

you can use case like below or Decode,
select Case
WHEN BMC_CORE_BMC_BASERELATIONSHIP.Name = 'SYSTEMOS'
Then BMC_CORE_BMC_BASERELATIONSHIP.DESTINATION_INSTANCEID
WHEN BMC_CORE_BMC_BASERELATIONSHIP.Name = 'ELEMENTLOCATION'
Then BMC_CORE_BMC_BASERELATIONSHIP.DESTINATION_INSTANCEID
When BMC_CORE_BMC_BASERELATIONSHIP.Name = 'APPLICATIONSYSTEMCOMPUTER'
Then BMC_CORE_BMC_BASERELATIONSHIP.DESTINATION_INSTANCEID
Else 'Ur Comments'
END
from BMC_CORE_BMC_BASERELATIONSHIP;
or Decode
select Decode( BMC_CORE_BMC_BASERELATIONSHIP.Name,'SYSTEMOS',BMC_CORE_BMC_BASERELATIONSHIP.DESTINATION_INSTANCEID,'ELEMENTLOCATION',BMC_CORE_BMC_BASERELATIONSHIP.DESTINATION_INSTANCEID,'APPLICATIONSYSTEMCOMPUTER',BMC_CORE_BMC_BASERELATIONSHIP.DESTINATION_INSTANCEID,else) from BMC_CORE_BMC_BASERELATIONSHIP;

Answer 2

am able to get the out put
create table BMC_CORE_BMC_BASERELATIONSHIP (name1 varchar2(100),id number);
insert into BMC_CORE_BMC_BASERELATIONSHIP (name1,id) values('SYSTEMOS',1);
insert into BMC_CORE_BMC_BASERELATIONSHIP (name1,id) values('ELEMENTLOCATION',2);
insert into BMC_CORE_BMC_BASERELATIONSHIP (name1,id) values('APPLICATIONSYSTEMCOMPUTER',3);
select Case
WHEN Name1 = 'SYSTEMOS'
Then id
WHEN Name1 = 'ELEMENTLOCATION'
Then id
When Name1 = 'APPLICATIONSYSTEMCOMPUTER'
Then id
Else id
END
from BMC_CORE_BMC_BASERELATIONSHIP ;
o/p #
1
2
3
select Decode(Name1,'SYSTEMOS',id,'ELEMENTLOCATION',id,'APPLICATIONSYSTEMCOMPUTER',id,id)
from BMC_CORE_BMC_BASERELATIONSHIP;
o/p #
1
2
3

Answer 3

Not sure if I understand you correctly and this is what you want... This is Oracle example where each column has own name or label. You can create table as select - just add create table as before the select and your column names will be the label names:
SELECT ename, empno,
(CASE deptno WHEN 10 THEN 'Accounting' END) dept10
, (CASE deptno WHEN 20 THEN 'Research' END) dept20
, (CASE deptno WHEN 30 THEN 'Sales' END) dept30
, (CASE deptno WHEN 40 THEN 'Operations' END) dept40
FROM scott.emp
ORDER BY ename
/
ENAME EMPNO DEPT10 DEPT20 DEPT30 DEPT40
