Have you ever executed a query from the MySQL command line client only to find that the output wrapped and the result is unreadable? In the past you have to run the query again with \G instead of ; or \g to get it to display the output in a vertical mode. My feature in MySQL 6.0.4 fixes that. The auto-vertical-output option tells the command line client to display the results in vertical format if the results are going to be too wide to display horizontally. It does this without re-executing the query because MySQL passes the length of each column in the result set. If the client isn’t able to determine the width of the screen it will default to 80 chars.
