I have a table \"Patient\" which has 5 fields.
CREATE TABLE PATIENT
(PAT_ID CHAR (4) PRIMARY KEY,
PAT_NAME VARCHAR (7),
ADMITTED DATE,
ROO
It turns out you're actually using Oracle Database. I'm still not sure exactly which fields you're trying to concatenate in which way, but this should be enough to get you rolling:
CREATE VIEW PATIENT_REPORT
AS
SELECT
PATIENT.PAT_ID||' '||PATIENT.PAT_NAME as "patient",
PATIENT.DOCTOR||' '||PATIENT.ROOM||' '||PATIENT.ADMITTED as "details"
FROM PATIENT;
