MySQL - Getting the percentage of an occurrence
I'll do my best to explain what I'm trying to accomplish.
I have a table called "Actions" and in Actions I have a column called "Resolution". In resolution some the entries, as an example, are "Fail", "Pending", "Completed" and "Cancelled".
I am trying to write a query that will tell me what percentage of the entries are "Cancelled". I hope I've explained myself. I am fairly new to SQL so please bear with me.
To get the percentage you need to divide the sum of the value, with the total and multiply by 100 to get a percentage.
resolution='Cancelled'is an expression returning 0 for false, or 1 for true.
SELECT SUM(resolution='Cancelled')*100/count(*) FROM table
