Hello

I am hoping that there is some way in SQL to combine the values of 2 columns into one in the ResultSet. Can you tell me if this is can be done?

Teachers

teacher       class
-------------------------
Mr Doyle     Math

Supervisors

supervisor     class
---------------------------
Mr Reid          Math


I want to display the following:

class              teachers
--------------------------------
Math              Mr Doyle, Mr Reid


Any suggestions?

On both of those - "ORA-01722 - invalid number".  I am using an oracle db by the way...

What does it mean to be "Always On"?

Is your cloud always on? With an Always On cloud you won't have to worry about downtime for maintenance or software application code updates, ensuring that your bottom line isn't affected.

Don't know oracle, but since the error say's invalid number it probably aspected numbers in the columns. Try to replace the + with &

You can comabine two columns using concatenating operator || (double vertical bars).
So it shou;d be something like this:

SELECT dbo.Supervisors.class, RTRIM(dbo.Teachers.teacher) || ', ' || dbo.Supervisors.supervisor AS Teacher FROM dbo.Supervisors INNER JOIN dbo.Teachers ON dbo.Supervisors.class = dbo.Teachers.class
