从表中删除行时的权限
我有一个表，其中的行具有重复的 userId。我正在尝试将行删除为
delete from table_name where userId=123
仅当我向数据库授予选择和删除权限时，此查询才有效。是否必须授予选择权限？
I have a table with rows having duplicate userId's. I am trying to delete the row's as
delete from table_name where userId=123
This query works only if I give both select and delete permissions to the database. Is is compulsory to grant the select permission?

目标表需要 DELETE 权限。如果语句包含 WHERE 子句，则还需要 SELECT 权限。这是来自微软的链接，请参阅权限部分

DELETE permissions are required on the target table. SELECT permissions are also required if the statement contains a WHERE clause. Here is link from microsoft, refer permission section
