Hello Friends,

i have the following list in mySql Database:

name	word		 	hit
		
Bill	performance		2
Anna	performance		5
John	performance		3
Bill	java			0
Anna	java			1
John	java			3
Bill	test			4
Anna	test			5
John	test			1

but i need it to be like that:

name	sum(hit)		words_count
	
Bill	6		performance = 2  java = 0, test = 4
Anna	11		performance = 5  java = 1, test = 5
John	7		performance = 3  java = 3, test = 1

I cant manage to write a sql statement to get the results like that.
Could you guys please give me a hint. i've been trying it all day.

Thanks a lot in advance

What I have tried:

sum(), groupby, subquerys, google

Solution 1

Start here: SQL GROUP BY Statement[^]
You'll probably need to use a couple of those, combined with SQL Joins[^]

Solution 2

I found it out. Thanks anyway.

 SELECT name, sum(hit) as points,
   GROUP_CONCAT(concat(word, '->'), concat(hit, ' ') separator ' ' ) as words
FROM results
GROUP BY name;
