由 扶醉桌前 提交于 2019-12-11 05:35:25
问题 I've been successfully able to use a dense_rank() over (order by...) which AFAIK is a window function - in postgres' row level security policy conditions. However, the documentation states Any SQL conditional expression (returning boolean). The conditional expression cannot contain any aggregate or window functions (emphasis is mine). Can someone explain this restriction and give an example where it applies? Thanks. 回答1: Basically, it tells you that each row is independent in regard of row

问题 I am using prisma and yoga graphql servers with a postgres DB. I want to implement authorization for my graphql queries.

The part I am stuck on is row level security - filtering rows by the data they contain - say I want to allow a logged in user to

问题 I want to implement column level and row level access control on data stored in my MySQL database. I am using NodeJS on my server, what's the way to go for this ? I see SAP Hana allows that but want to keep MySQL. 回答1: There are three approaches you could take: Do it within the app Do it between the app and the db, inside a db proxy Do it inside the database The first option wouldn't really qualify as row-level access control since the application logic is the one responsible for the
