What is the name of the "quantity" column?

Question

MySQL

Suppose we need to add a `user`column to the table `кол-во групп в которых он участвует`, but what exactly should we call this column?

`groups_amount`
`groups_quantity`
`groups_qty`
`groups_sum`
`groups_count`
`groups_total`
`groups_num`
...

Maybe there is some RFC on this topic? Or something common...

Answer 1

group_count
