Question

I have a mysql table , which holds data like this.

Name    |how_out    |runs
------------------------------
Robin   |Not out    |45
Robin   |lbw        |25
Robin   |caught     |50
Robin   |caught     |0
Robin   |bowled     |30
Robin   |bowled     |0
.
.
.

I want one SQL query, which returns the following columns

Name , Total_runs , Average

Sounds simple enough, but the only problem for me is that.
In cricket , average is just not Sum( runs)/count(*)
it’s Sum(runs)/Count of number of innings where how_out is not ‘Not out’

Could some one tell me how to write one such query ?

The query that i wrote gave the wrong average for obvious reasons.
The query that i wrote was

Select `Name`,sum(`runs`) as 'Total_runs', Sum(`runs`)/count(*)
From `batsman_stats`
group by `Name`
order by 2 desc

Could sql experts please help me ?

Thanks

Answer 1

Select `Name`,sum(`runs`) as 'Total_runs', Sum(`runs`)/sum(if(how_out <> 'Not out',1,0))
From `batsman_stats`
group by `Name`
order by 2 desc
