先查看该用户是否拥有全局 Insert 权限：

```sql
select Insert from mysql.user where user='test' and host='%';
select Insert_priv from mysql.user where user='test' and host='%';
```

如果没有，再查看该用户是否拥有 `db1` 数据库级别的 Insert权限：

```sql
select Insert from mysql.db where user='test' and host='%';
select Insert_priv from mysql.db where user='test' and host='%';
```

如果仍然没有，则继续判断是否拥有 `db1.t` 这张表的 Insert 权限：

```sql
select tables_priv from mysql.tables_priv where user='test' and host='%' and db='db1';
select table_priv from mysql.tables_priv where user='test' and host='%' and db='db1';
```
