Gorm How to modify sql before execute it and after build it?

Your Question

I want to modify sql which created by gorm before executed. How can I do?

I tried to create a "before" callback method, but it will be executed before create sql. I can't get sql from "originalSQL := db.Statement.SQL.String()". If you have any idea, please help.

The document you expected this should be explained
