There are many ways to test and edit files. A lot of developers only use their favorite Integrated Developer Environment (IDE) but I find testing script files within the scope of a pipelined set of scripts much faster.

The ability to edit a script from within the MySQL Command-Line Interface (CLI) or MySQL Shell would be nice but unfortunately, doesn’t exist. You can always subshell to edit a file or list files in the present working directory, like:

mysql> \! vi task.sql

I prefer to test at the OS level while leveraging the up-arrow key for command history. Here’s my quick edit and test script technique from your present working directory:

1. Assume you create a task.sql test file, like:

   SELECT user() AS "Current User"\G
   

2. You can edit with vi or emac and test the script interactively from the present working directory.

So your MySQL server has crashed.  What do you do now?  When a server is down, in my opinion, there are two steps that are essential and both are extremely important and neither should be neglected:

1. Save diagnostic information for determining the root cause analysis (RCA).
2. Get the server back up and running.

Too many people rush to Step #2 and lose pertinent diagnostics from Step #1.  Likewise, too many people will spend too much time on Step #1 and delay getting to Step #2 and restoring service.  The goal is to collect diagnostics as quickly as possible for later review while getting service restored as fast as possible.

As a Technical Account Manager (TAM) and assisting on server restoration calls, I have seen both issues at play.  Technical resources have a tendency to get so bogged down in trying to understand the cause of the server outage that they …
