There are two columns in a MySQL table: SUBJECT and YEAR.

I want to generate an alphanumeric unique number which holds the concatenated data from SUBJECT and YEAR.

How can I do this? Is it possible to use a simple operator like +?

You can use the following SQL query to concatenate SUBJECT and YEAR columns in a table:

SELECT CONCAT ('SUBJECT', '  ', 'YEAR') as new_column from Table_Name

The second argument is to create space between SUBJECT and YEAR columns after concatenating.

I recommend going through this SQL tutorial to learn more about CONCAT() function.
