Question

I know mysql has the MIN() function pulls out the smallest value located in a specific column.
I was wondering is there a way to pull out the smallest value for each corresponding id and exclude the values that equal 0?

For example, the 2 ids have multiple prices that were entered. I need to exclude ‘0’, and then pull out the min for 1, and then the same for 2, etc etc.

id     price
=============
1       0
1       33.0
1       21.7
2       0
2       99.22

Answer 1

Should be something like

select id, min(price) from t where price > 0 group by id;
