Hi, I am currently working on joining 2 tables, however those tables have different number of columns thats why I have difficulty on joining them. I tried to use FULL OUTER JOIN, close result but still not my expected output.
You can kindly see my attachment to see the scenario.
Oracle Sql Query:
SELECT a.id, b.firstName, b.lastName, b.midInitial, a.project, a.manager
FROM table1 a
FULL OUTER JOIN
WHERE a.id = b.id
By the way, I'd used this query to that expected scenario and still not getting same on that screenshot. Hoping someone who can guide me to this. Thanks.
SELECT CASE WHEN NVL(a.id, '') = '' THEN b.id ELSE a.id as ID
, NVL(b.firstName, '-') as [First Name]
, NVL(b.lastName, '-') as [Last Name]
, NVL(b.midInitial, '') as [Middle Iniital]
, NVL(a.project, '-') as [Current Project]
, NVL(a.manager, '-') as [Assigned Manager]
FROM table1 a
FULL OUTER JOIN table2 b on a.id = b.id
Finally I made it working and through corrections I made from sandeepmittal11 (many thanks to him)
Here is my final sql that matches on my attached screenshot.
WHEN nvl(t2.userid,'') IS NULL
THEN t1.userid else t2.userid
nvl(t2.first_name,'-') as First_name,
nvl(t2.middle_initial,'-') as Middle_Initial,
nvl(t1.current_project,'-') as Current_Project,
nvl(t1.manager,'-') as Project_Manager
FROM table1 t1
FULL OUTER JOIN table2 t2 ON t1.userid = t2.userid
ORDER BY t1.userid
