回復 四台國際CEO #1 的帖子
"Some" and "All" are keywords in SQL (relational database query language).
"All" means the whole set of items.
"Some" means at least 1 item in the set.
For example, the statement
select * from table_T where attribte_A >some in {A, B, C, D}
The selected tuple from table_T can have attribute_A greater than any one item
in the set {A, B, C, D}.
If attribute_A of the selected tuple is greater than all items in the set is also valid.
But for everyday usage, "Some" does not mean "all".
So I think any value between 1 to 14 can be a valid answer.
