If Statement in Select (Oracle)

Hi I have simply select and works great:
select 'CARAT Issue Open' issue_comment, i.issue_id, i.issue_status, i.issue_title, i.ISSUE_summary ,i.issue_description, i.severity,
gcrs.Area_name, gcrs.sector_name,
substr(gcrs.stream_name,1,case when instr(gcrs.stream_name,' (')=0 then 100 else instr(gcrs.stream_name,' (')-1 end) ISSUE_DIVISION,
case when gcrs.STREAM_NAME like 'NON-GT%' THEN 'NON-GT' ELSE gcrs.STREAM_NAME END as ISSUE_DIVISION_2
from table(f_carat_issues_as_of('31/MAR/2013')) i
inner join v_gcrs_with_stream gcrs on i.segment_id = gcrs.segment_id
where UPPER(ISSUE_STATUS) like '%OPEN%'
Now I want to call two columns: ISSUE_DIVISION and ISSUE_DIVISION_2
if they are equal in new columns should be value 1 if are not equal should be 0,
how can I do it ?
my full code:
select 'CARAT Issue Open' issue_comment, i.issue_id, i.issue_status, i.issue_title, i.ISSUE_summary ,i.issue_description, i.severity,
gcrs.Area_name, gcrs.sector_name,
substr(gcrs.stream_name,1,case when instr(gcrs.stream_name,' (')=0 then 100 else instr(gcrs.stream_name,' (')-1 end) ISSUE_DIVISION,
case when gcrs.STREAM_NAME like 'NON-GT%' THEN 'NON-GT' ELSE gcrs.STREAM_NAME END as ISSUE_DIVISION_2
from table(f_carat_issues_as_of('31/MAR/2013')) i
inner join v_gcrs_with_stream gcrs on i.segment_id = gcrs.segment_id
where UPPER(ISSUE_STATUS) like '%OPEN%' and
CASE WHEN ISSUE_DIVISION = ISSUE_DIVISION_2 THEN
CASE WHEN ISSUE_DIVISION is null then "Null Value found"
Else 1 End
ELSE 0 END As Issue_Division_Result
but I get error on line: ELSE 0 END As Issue_Division_Result
ORA-00920: invalid relational operator :(

SELECT (CASE WHEN ISSUE_DIVISION = ISSUE_DIVISION_2 THEN 1 ELSE 0 END) AS ISSUES
-- <add any columns to outer select from inner query>
FROM
( -- your query here --
select 'CARAT Issue Open' issue_comment, ...., ...,
substr(gcrs.stream_name,1,case when instr(gcrs.stream_name,' (')=0 then 100 else instr(gcrs.stream_name,' (')-1 end) ISSUE_DIVISION,
case when gcrs.STREAM_NAME like 'NON-GT%' THEN 'NON-GT' ELSE gcrs.STREAM_NAME END as ISSUE_DIVISION_2
from ....
where UPPER(ISSUE_STATUS) like '%OPEN%'
)
WHERE... -- optional --
So simple you can use case statement here.
CASE WHEN ISSUE_DIVISION = ISSUE_DIVISION_2 THEN
CASE WHEN ISSUE_DIVISION is null then "Null Value found" //give your option
Else 1 End
ELSE 0 END As Issue_Division_Result
In one line, answer is as below;
[ CASE WHEN COLUMN_NAME = 'VALUE' THEN 'SHOW_THIS' ELSE 'SHOW_OTHER' END as ALIAS ]
use the variable, Oracle does not support SQL in that context without an INTO. With a properly named variable your code will be more legible anyway.
