Question

I’ve been looking around for a solution, but I can’t find a straightforward answer.

I want my oracle select statement to separate columns based on commas. So, let’s say I have a query like this:

Select * from people

Results:
Name Age 
Bob  4
Sam  5
Joe  7

I want the results to be:

Bob,4
Sam,5
Joe,7

How can I do this?

Answer 1

Use Concatenation ||, and select the values with the comma between them.

SELECT NAME || ',' || AGE
FROM
(
    SELECT 'BOB' NAME, 4 AGE FROM DUAL
    UNION ALL
    SELECT 'SAM' NAME, 5 AGE FROM DUAL
    UNION ALL
    SELECT 'JOE' NAME, 7 AGE FROM DUAL
)
