Sql 如何将行中的多个值标记为单个列？

我将多个产品标记为相同的ID，我想在单个列中用“/”分隔产品，显示一次ID

如果123在单独的行中有A和B，那么输出在不同的列中应该是1 A/B

select
d.*, 
case when d.col = 'A' AND d.loan_class = 'B'
then 'A/B'
else 'NA'
end name
From tab D
where id = '1'
Group By ....;

那不是

listag

select id, 
       listagg(product, '/') within group (order by null) list_of_products
from your_table
group by id
