描述

Somewhere in the macro expansion, there is code that imports ops from within diesel. If a column in a database is named ops, this causes conflicts within the macro.

I think that putting a note somewhere that this could happen may be enough; however, prefixing the internal variables or module names to something like _table_ops or something similar would be a more permanent solution.

研究方向
Investigate the `infer schema!` macro implementation in the diesel codebase. The issue arises because the macro imports `ops` from diesel internally, conflicting with a table column named `ops`. A possible fix is to prefix internal variable names like ` table ops` to avoid name conflicts. Key files to look at include the macro definitions in the `diesel` crate.
