Case to populate field

Question

looking for little help.
I have a table with a field called open_closed
im inserting data into this table via a procedure from another table.
What im looking to do in the sp is when insert is happening, update this field old_new with the word "closed" if another field in the table has certain data in it.
Trying case like this.
insert into ME.MASTER (request_num,request_url,logged_date,form_status,requestor_business_segment,requestor,requestor_email,d2.open_closed)
SELECT d1.request_num,d1.request_url,d1.logged_date,d1.form_status,d1.requestor_business_segment,d1.requestor,d1.requestor_email
FROM
ME.STG_TABLE d1,
(select CASE WHEN 'current_role'='Approve_NO' THEN 'OPEN_CLOSED'='CLOSED'
          WHEN 'current_role'='Approve_YES' THEN 'OPEN_CLOSED'='CLOSED'
     END
          FROM ME.STG_TABLE
)d2does this look right ?

)d2does this look right ?Try it. Does it do what you want?
If you get an error meesage, post the complete error message, including line number.
If you get the wrong results, point out where the results are wrong, and describe how you would get the right results in thiose places.
In any evert, post CREATE TABLE and INSERT statements, as they exist before the INSERT that you posted, so people can re-create the problem. Post the contents you want to be in the changed table after the problem INSERT is over.
Always say which version of Oracle you're using.
Remember what a CASE expression does: it returns a single value in one of the SQL data types, such as VARCHAR2. That means all the expressions after the THEN keywords have to evaluate to single values in one of the SQL data types. There is no BOOLEAN data type in SQL, so
THEN 'OPEN_CLOSED'='CLOSED'is one obvious problem.
This condition is syntactically correct:
'current_role'='Approve_NO' but it will never be TRUE. the 12-character sting 'current_role' is not the same as the 10-character string 'Approve_NO'. If current_role or approve_no are column names, then they shouldn't be in quotes.
