The Orm,linq of the DotNet system, which is mostly Linq, is very good, eliminating the developer's reliance on SQL. But it ignores the fact that SQL itself is not complex, and that it is difficult for developers to write Linq to generate good performance SQL in complex query scenarios, and I believe that students who have used EF must have this experience: "I think about how SQL writes, and then I write Linq, It's over. You may also want to see what SQL output of Linq is like. " It was a very bad experience. To be absolutely optimized for SQL, developers must have absolute control over SQL. In addition, SQL itself is very simple, why add a layer of translators?
