For example I have
例如我有
select * from products where producttype=magazine
select * from products where producttype = book
I have to combine the result of these two queries, and then output it as one single result. I have to do this inside a stored procedure.
我必须将这两个查询的结果结合起来,然后将其作为一个结果输出。我必须在存储过程中执行此操作。
PS These are just examples I provided, i have a complex table structure. The main thing is I cannot join them.

I think that magazin and book are varchar values and not columns in your table
我认为 magazin 和 book 是 varchar 值而不是表中的列
select * from products where producttype in ('magazine', 'book');
