Question

There is a table like follow:

Player    Weight    Hight    Agility
____________________________________
ABC        135       70         4
XYZ        155       65         1
PQR        121       69         7
MNO        171       73         5

I need a “Player Score” for each player, which is simply one point for each satisfied condition.

Example Conditions:
Weight < 150
Height > 67
Weight / Height < 1.8
Agility > 4

Thus based on above, the result might be:

Player     Score
________________
ABC          2
XYZ          0
PQR          4
MNO          2

Is it possible to achieve above using MYSQL ?

Answer 1

Look up MySQL flow control and try something like this…

select player, (CASE when Weight < 150 then 1 else 0) + 
               (CASE when Height >  67 then 1 else 0) +
               (CASE when weight <  1.8*height then 1 else 0) +
               (CASE when Agility > 4  then 1 else 0)
