Querying MS SQL Server: Using STUFF Function (Trans-SQL)
Write an SQL query that displays book title, ISBN, and authors for each title.
If there are multiple authors, display them all together in one line,
each name separated by a ‘|’ character.
NOTE: This is similar to concatenating strings, but in this context normal concatenation will not work. Instead, we will use STUFF function to get the desired results.
