getting error while executing case statement - sql

Question

I am trying to execute case statement but i am getting an error. Here is my query
select LOSA_APP.app_ref_no AS "App.Ref.No.", CODE_BRANCH.branch_name AS "BRANCH"
from losa_app LOSA_APP
INNER JOIN
losa_app_z LOSA_APP_Z
ON
losa_app.app_ref_no = losa_app_z.app_ref_no
INNER JOIN
code_branch CODE_BRANCH
ON
LOSA_APP.attend_branch = CODE_BRANCH.branch_id
where
LOSA_APP.app_status='A' -- Application Status in {‘accepted’}
and
trunc(sysdate) between (nvl(LOSA_APP_Z.li_dt, LOSA_APP_Z.li_collect_dt)) AND ((trunc(sysdate))) -- falling under the reporting period
and
(trunc(sysdate) - nvl(losa_app_z.li_dt,losa_app_z.li_collect_dt)) > 90 -- select application cases at any step after entering Documentation flows.
and
losa_app.product_type = 'MG' -- Select records based on input parameter value passed in.
and
case :input1
when 'ABB' Then code_branch.branch_code1 like '%0232%'
when 'AiBB' Then code_branch.branch_code1 like '%0347%'
end
While executing it asks me for input. After that it gives me error that
ORA-00905: missing keyword
00905. 00000 - "missing keyword"
*Cause:
*Action:
Error at Line: 22 Column: 50
Line 22 is when 'ABB' Then code_branch.branch_code1 like '%0232%'
What keyword i am missing?
Thanks

Answer 1

Don't try to return a logical boolean from the CASE statement.
Instead, make the CASE statement part of the logical test. Such as...
code_branch.branch_code1
like
case :input1 when 'ABB' Then '%0232%'
when 'AiBB' Then '%0347%' end

Answer 2

try this one
SELECT ....
FROM...
WHERE ....
AND
(
((:input1 = 'ABB') AND code_branch.branch_code1 like '%0232%') OR
((:input1 = 'AiBB') AND code_branch.branch_code1 like '%0347%')
)
