## sync-diff-inspector 所需的数据库权限

sync-diff-inspector 需要获取表结构信息、查询数据，需要的数据库权限如下：
sync-diff-inspector 需要具备特定的数据库权限以获取表结构信息、查询数据。你需要在上游数据库和下游数据库中授予以下权限：

- 上游数据库
- `SELECT`：用于对比数据。
- `RELOAD`：用于查看表结构。

- SELECT（查数据进行对比）

- SHOW_DATABASES（查看库名）

- RELOAD（查看表结构）

- 下游数据库

- SELECT（查数据进行对比）

- SHOW_DATABASES（查看库名）

- RELOAD（查看表结构）
> **注意：**
>
> - **请勿**在所有数据库 (`*.*`) 上授予 [`SHOW DATABASES`](/sql-statements/sql-statement-show-databases.md) 权限。否则，sync-diff-inspector 会尝试访问无权限的数据库，导致报错。
> - 对于 MySQL 数据源，请确保系统变量 [`skip_show_database`](https://dev.mysql.com/doc/refman/8.4/en/server-system-variables.html#sysvar_skip_show_database) 设置为 `OFF`。如果该变量设置为 `ON`，检查可能会失败。
