"""只读比对脚本：逐列比对 pms_dev(测试) 与 pms(生产) 的**全部**列定义
|
|||
|
|
|
|||
|
|
比对维度：COLUMN_TYPE / IS_NULLABLE / COLUMN_DEFAULT / EXTRA / COLUMN_COMMENT
|
|||
|
|
另外单独统计两库是否还残留 `TIMESTAMP` 列（本项目禁止：sqlx 只能把它解码成 DateTime<Utc>，
|
|||
|
|
而 Rust 侧时间列全是 NaiveDateTime/Option<NaiveDateTime> ⇒ 接口 500）。
|
|||
|
|
|
|||
|
|
用法： python .tmp-schema-align/compare_full.py
|
|||
|
|
只发 SELECT，不做任何写入。
