We only recommend using the following two forms of SQL for parameter binding data insertion:
```sql
1. INSERT INTO meters (tbname, ts, current, voltage, phase, location, group_id) VALUES(?, ?, ?, ?, ?, ?, ?)
2. INSERT INTO ? USING meters TAGS (?, ?) VALUES (?, ?, ?, ?)
a. Subtables already exists:
1. INSERT INTO meters (tbname, ts, current, voltage, phase) VALUES(?, ?, ?, ?, ?)
b. Automatic table creation on insert:
1. INSERT INTO meters (tbname, ts, current, voltage, phase, location, group_id) VALUES(?, ?, ?, ?, ?, ?, ?)
2. INSERT INTO ? USING meters TAGS (?, ?) VALUES (?, ?, ?, ?)
```

我们只推荐使用下面两种形式的 SQL 进行参数绑定写入：
```sql
1. INSERT INTO meters (tbname, ts, current, voltage, phase, location, group_id) VALUES(?, ?, ?, ?, ?, ?, ?)
2. INSERT INTO ? USING meters TAGS (?, ?) VALUES (?, ?, ?, ?)
一、确定子表存在：
1. INSERT INTO meters (tbname, ts, current, voltage, phase) VALUES(?, ?, ?, ?, ?)
二、自动建表：
1. INSERT INTO meters (tbname, ts, current, voltage, phase, location, group_id) VALUES(?, ?, ?, ?, ?, ?, ?)
2. INSERT INTO ? USING meters TAGS (?, ?) VALUES (?, ?, ?, ?)
